G'day Jerry, I don't think there's anything wrong with your ARISSatTLM, as I've only been getting KURSK-944s since the 13th. My last 'proper good' experiment frame was: 2011/08/11-08:12:48 Received Kursk frame 2 with MET=650105 len=516. Satellite MET around then was: 2011/08/11-08:12:54 Received telemetry frame with MET=653412 Len=371 I missed the 12th, and on the 13th the telemetry and experiment MET had reset: 2011/08/13-04:34:16 Received telemetry frame with MET=2514 Len=371 ... 2011/08/13-04:34:24 Received Kursk frame 3 with MET=944 len=516. Do we have <C:\Users\Ben\Desktop\ARISSatTLM\Kursk\KURSK-944.3>? 2011/08/13-04:34:24 No. Saving to <C:\Users\Ben\Desktop\ARISSatTLM\Kursk\KURSK-944.3>. And from that point on, I have only received KURSK-944 frames (which are still auto-forwarding). 2011/08/17-05:30:04 Received Kursk frame 5 with MET=944 len=48. Do we have <C:\Users\Ben\Desktop\ARISSatTLM\Kursk\KURSK-944.5>? 2011/08/17-05:30:04 Yes. <C:\Users\Ben\Desktop\ARISSatTLM\Kursk\KURSK-944.5> exists. 73, Ben VK2FBRB On Wed, Aug 17, 2011 at 11:08 PM, <n0jy(a)lavabit.com> wrote: > A question for all, for a few days now my ARISSatTLM has been reporting > the Kursk as being (I believe, I'm not at home to check right now) > something like Kursk-944.x or perhaps it was Kursk-444.x (some real low > perhaps hung up on that and needs a restart?

ARRISSat-1 Heard Passing Over Cuba
by Mike Schaffer 17 Aug '11

17 Aug '11

On Wednesday, August 17 heard a very weak ARISSat-1 on 2M 145.950 FM pass over northeast Camaguey, Cuba for less than thirty seconds in SSTV mode. Minutes later it was tracking northeast towards northern Cat island, The Bahamas at 2242 UTC. Azimuth 139, Elevation +22 according to my satellite tracking program. 73's Mike Schaffer KA3JAW Tampa, Florida EL87

Beaconers
by Kevin Deane 17 Aug '11

17 Aug '11

Bob is absolutely right, the people beaconing on 145.825 are ruining it for others. Which reminds me of the spanking I got for using FM on the SSB birds, I am sure there would be a lot bigger stink if people were affecting those satellites and not just the poor forgotten and obviously abused NO-44, and the countless people trying to talk to beacons on the ISS... I like my call showing up on the ISS/NO-44 page just as much as the next guy, but I do it myself not while I am at work or sleeping. Thanks by the way for the recent fun contacts on the ISS, I am sure the beacon comments were just as well veiwed as the Qso's... Kevin KF7MYK

ARISSAT-1 report

17 Aug '11

Hi All, Just popped outside from the IARU Region 1 Conference meeting to catch an ARISSAT pass. Good signals with an Arrow and a FCD and also using a G0MRF prototype filter amplifier with 5v being supplied by the Dongle. (Thanks David for the loan) Voice telemetry reported MET of 41 mins - which corresponds very well to when it left eclipse over the Pacific. Battery volts 35.74 and current -4ma I just failed to identify a ZS station using the transponder! The signal had no fading but several occasional ~ 100 msec breaks in transmission were noted. best 73 from sunny ZS6 land Graham G3VZV

MARK AUSTIN KB1GRV
by Pete Norris 17 Aug '11

17 Aug '11

Hi all:I received this from Phil, N1EP. I thought there would be a number of you that might like to know.Pete, K1HZU Hello Folks, If you have not heard already, local (Franklin/Ellsworth) ham Mark Austin, KB1GVR, became a silent key on August 8. Graveside services will be this Thursday, Aug 18, at 11AM at Woodbine cemetery in Ellsworth. Mark was very prolific in space communications. In 2002, he told me that he was listening to his scanner, I think in 1997, and heard Russian voices coming over the speaker about every hour and 36 minutes. He discovered the voices were from cosmonauts on board the Mir Space Station. He then started recording their SSTV broadcasts and then went out and bought his first computer so he could see the pictures he had previously recorded from the Soviet slow scan TV transmissions. That inspired him to earn his ham ticket so he could talk to the cosmonauts. And talk, he did. Since then, Mark has become well known aboard the space shuttles and International Space Station by many astronauts and cosmonauts. Not only has Mark talked to them on voice mode, but became extremely proficient at using the space station and satellites to communicate digitally. He even discovered a new way of using one particular satellite to extend communication capability. Mark had the opportunity to meet some of the spacemen he had befriended on-the-air when he made visits to Mission Control in Houston and to Kennedy Space Center, where he also was thrilled to watch a shuttle launch. His enthusiasm with space communications inspired many hams to give it a try, including myself. His advice was spot on so that I twice successfully made voice contacts to the space station. I also had fun with Oscar-14 with Mark's tips. If you operated an APRS station in Maine, you would recognize the KB1GVR call sign, as Mark was also an avid APRS fan. Mark's other pastimes included racing and flying with his brother in his plane where his same determination brought him lots of success, rewards, and joy. The walls of Marks home were decorated with the many ham radio and racing certificates and awards he had earned and his vast collection of space communications QSL cards is amazing, as many EAWA members can attest to as Mark has brought them in for display in the past. Mark was only 50 years old, but in his too-short life, he accomplished a lot. As N1DP said on last night's Washington County ARES Net, Godspeed Mark. We will miss you. 73, Phil Duggan, N1EP

Hi all, We understand that the Edusat spacecraft from Italy has been successfully launched today from Yasny on a DNEPR launcher. It has apparently been granted an experimental licence by the Italian Telecommunications Ministry to transmit on 435.750MHz but this frequency was not submitted for coordination by the the IARU Frequency Coordination Panel. We understand that it may only be transmitting when over Rome and that it will use 9k6 GMSK 73 Graham G3VZV

ARISSat-1 Pass Over DO33 2011-08-17
by B J 16 Aug '11

16 Aug '11

I acquired the FM downlink signal at 0600 UTC and heard part of the diagnostic message and the ID. The signal initially wasn't clear but it improved by 0602 with little noise, strength of at least S8, and no fading. At 0602, the following was transmitted after the ID and greeting: MET = 65 minutes IHU temp. = +41 deg. C Control panel temp. = +56 deg. C Battery voltage = ?? The transmission appeared to stop at that point and nothing further was heard. 73s Bernhard VA6BMJ @ DO33FL

My first try on the arissat-1 transponder.
by Eric Knaps, ON4HF 16 Aug '11

16 Aug '11

Hello, I just had a 17 degree pass of arrissat-1 here. On 145.950 FM I heard sstv and international greetings. When the sat was transmitting on 145.950 the transponder was active and I could here myself but the signal was weak. When I couldn't hear myself anymore I noticed the transmisions on 145.950 has also stopped. When greetings came back, transponder was back also. Setup: Yaesu FT-847 with 50 watts. Antennas: 12 element yagi for uplink and 7 element yagi for downlink, both vertical mounted. I made a recording if anybody is interested to hear it. 73, Eric. -- Amateur Radio Station ON4HF Eric Knaps Satellite manager UBA Tel. +32472985876 (mobile) http://www.on4hf.be

ARISSat-1 Voice Telemetry 03:44z 8/16/2011
by Greg D. 16 Aug '11

16 Aug '11

An annoyingly high pass this evening (79 degrees, on the wrong side of a South-centered rotor)... 03:44z 8/16/2011 MET = 60 min IHU temp = +39c Control panel temp = +29c Battery = 35.58v Charge = -20ma Satellite appeared to switch to low power mode right before this, as there were a couple of voice greetings ("Hi this is ARISSat-1") prior to the telemetry, then 2 minutes of silence. When the satellite came back after the 2 minute pause, I tried hitting the transponder with some CW dits. Nothing heard on the downlink, though my rotor was horribly mispositioned at the time (ref the afore mentioned annoyingly high pass...). Greg KO6TH

ARISSat-1 Battery
by Anthony Monteiro 15 Aug '11

15 Aug '11

Dear Friends, This is speculation but it looks to me like we have had a bit of good luck regarding the battery. Looking at the battery voltage from deployment on... Up until Aug 11, the battery seems to be deteriorating "normally" with a slight downtrend in the max voltage as expected. But on Aug 11, the battery voltage suddenly rises up to 36 V max and the satellite has started resetting in eclipse. I think the explanation is that the battery experienced a significant event on Aug 11 where it lost the electrolyte in one or more cells. If this is true, the bad news is that it will no longer hold a charge and will not operate in eclipse any more. But the good news is that without electrolyte, it would also stop dendrite growth that causes the eventual battery short circuit. In our ground testing, our test battery failed in the usual way with the battery load increasing until the solar panels could not drive the power bus high enough to run the satellite. But interestingly, several cells also cracked and dumped their electrolyte during this testing. If a cell on the flight battery cracked and dumped its electrolyte BEFORE the shorts were formed, it should stay that way and the satellite may very well continue to operate in the sun until it starts to re-enter. We just need some luck to avoid a bad solar angle that would cause a reset in sunlight. Keep your fingers crossed! :) 73, Tony AA2TX

I also heard the "secret word", but it was different than the last time (a few days ago). Is there more than one per language (both were in English)? Greg KO6TH

Telemetry Data
by Dianne 14 Aug '11

14 Aug '11

Hello, You asked for "emergency mode" data, and I'm not sure what you meant, but I have some that may or may not qualify. We are located in San Diego, California At 03:07 UTC (8:07 PM PDT (local)) MET was 62 minutes IHU Temp was +45 degrees C Control Panel Temp was +50 degrees C Battery Voltage was 33.77 V Battery Current was -8 mA At 03:12 UTC (8:12 PM PDT (local)) MET was 67 minutes IHU Temp was +45 degrees C Control Panel Temp was +50 degrees C Battery Voltage was 35.73 V Battery Current was -8 mA The "secret words" that we heard were the ones from the two American boys ("Explore") and the two British girls ("Eagle") I don't know if that was what you were looking for, or if it was at all helpful, but I figured you'd rather have extra data than not. -Lindsay White KI6LZN www.mchsarc.com <http://www.mchsarc.com/>

Voice Telemetry just at going eclipse
by fohuchi＠jcom.home.ne.jp 14 Aug '11

14 Aug '11

Dear Sir, Attached are telemetry on FM voice for your study. During telemetry announcement, FM signal sttoped, maybe due to battery voltage down. August 14, 2011 at 1049 UTC, Telemetry on FM voice, just after AOS MET is ?? minutes (I could not copy with QSB/Noise) IHU Temp is plus ?? degrees C (I could not copy with QSB/Noise) Control Panel Temp is plus 61 degrees C Battery Voltage is 36.014 Battery Current is minus 4 milliAmps August 14, 2011 at 1051 UTC, Telemetry on FM voice MET is 69 minutes IHU Temp is plus 48 degrees C Control Panel Temp is plus 61 degrees C Battery Voltage is 36.014 Battery Current is minus 8 milliAmps August 14, 2011 at 1053 UTC, Telemetry on FM voice MET is 72 minutes IHU Temp is plus 48 degrees C Control Panel Temp is plus 6? degrees C Battery Voltage is 31. FM carrier stopped just at this point, after announcement of battery voltage drop down to 31 V. It is not LOS yet. Not calculated, but orbit prediction of this pass is VVN. Satellite goes into eclipse during this pass. I think ARISSAT1 lost solar panel power and stopped soon. I wish this data helps you. Thank you, Fujio JO1XWH

Thinking about ARISSat-2
by Burns Fisher 14 Aug '11

14 Aug '11

I know the ARISSat team is busy with bird #1, but I'm just thinking about lessons we might learn for version 2. I think it is great that we are getting so much data about the battery. Assuming that there might be another satellite launched from the ISS, we will still have the same man-rating issues, and thus the battery might need to be the same Russian space suit battery. If that were true, what might we take away from #1 to help with #2? It was hoped that many shallow charge cycles might keep the battery running longer than the few deeps cycles that it is spec'ed for. Sounds like we got maybe 10 days out of it before it started to deteriorate. What about another strategy? Suppose we did exactly what the battery was spec'ed for: Deep cycles. Let's say 333ma current draw and let's say that the battery is rated at 24Ah. So what if we only charged the battery every 3 days; maybe even turn off the transmitter while it charges. 5 cycles is 15 days. A bit better than this time. Maybe (also) we extend that 3 days between charges by only using the batteries in eclipse. This obviously requires additional electronics; in particular the battery can't be on the main power bus; we want to be able to isolate it to prevent it charging on every orbit. But that might be good anyway...the ability to isolate the battery might be desirable when the battery does die for good. Just thinking... Burns, W2BFJ

> As far as SATs go, what's presently flying or > near term planned for launch that will serve > as a message relay for nts type messages? Since all of the packet digipeating satellties can also transparently carry email, it was interesting the other day when Nick Pugh K5QXJ suggested that not only can APRS satellites EMAIL their telemetry directly to their makers, the controllers can also send commands directly back to the satellites via conventional APRS mail as well! For a satellite to email its telemetry directly to a callsign (for delivery by any worldwide email device) all it has to do is format its telemetry like any other APRS one-line email. Here is the format: PCSAT>APRS::EMAIL :[email protected] I'm OK: V=12, I=140, T=30C In this case PCSAT sends an email to WB4APR via his ARRL address with the words "I'm OK"... and then whatever other telemetry the satellite wants to include. This works this way because the global APRS system will take any packet anywhere that is addressed to "EMAIL" and then wrap it up into standard EMAIL and send it via the internet. Since all IGates on the planet including the ones that are monitioring the satellites automatically do this, then the system is in place. For the satellite operator to send back a command to the satellite this too is aoutamitcally handled in all existing IGate software. If an APRS message is seen anywhere on the planet addressed to any callsign, in this case, the callsign of a small satellite, then any IGate that is IN RANGE of the satellite at any instant (and has heard it) will attempt to transmit that packet onto the satellite uplink in real time. No one has done this yet I dont think, because most Satellite IGates have mostly just been used for downlink, and no one has tried this uplink before. The one thing that would have to change is the TIME-OUT time in the "has-been-heard" list of the IGates. As it is, an IGate will try to return a message to another callsign if it has been heard in the last 30 minutes or so. For satellites, we would want this to time out after only 10 minutes, since a LEO will be out of range by then. But it is possible. Might be fun. Bob, Wb4APR

what's flying that does packet
by Eric Fort 14 Aug '11

14 Aug '11

I may be going on an extended adventure which will take me far from the usual communications facilities of phone, internet, or even regular postal mail. This pretty much leaves HF and SAT as my options for messaging and communication with the outside world. As far as SATs go, what's presently flying or near term planned for launch that will serve as a message relay for nts type messages? Thanks, Eric AF6EP

Mike& Alan, Thank you so much for your reply to my question about the "Secret Word" contest. I sure do not want my post about the contest to imply that I am in a hurry to receive a certificate. I am so appreciative of those who volunteer and make programs like ARISSAT-1 so interesting, exciting, informative, and even habit forming. I have been an active ham for 50 years but relatively new to the satellite area. I have come to realize just how habit forming this facet of Amateur Radio is. I plan my life around the acquisition and loss of signals, having the radio prepared with the appropriate software running, antenna positions, and on and on. I sincerely thank everyone who contributes to the many pieces that make the satellite puzzles complete. OMG, now a contest to guess (you smart folks probably know!) when ARISSAT-1 will reenter. This will be like losing a family member! Mine will only be a guess...discussing death is hard to do!

Re: 436CP42UG polarity switch update manual of M2 ???
by Alan P. Biddle 14 Aug '11

Juan, The instructions for the polarity switch were written for the shorter version of the antenna. There are some differences in the installation for the 42 element version. Attached to the direct mail is copy of a more recent version than you have. It helps with some, but not all, of the issues. The drawing has the new dimensions for the rear shorting bar. There is a note for the front shorting bar saying "Shorting bars remain here at 4.375 inches." Hope this helps. 73s, Alan WA4SCA -----Original Message----- From: amsat-bb-bounces(a)amsat.org [mailto:[email protected]] On Behalf Of Juan Antonio Fernandez Sent: Sunday, August 14, 2011 1:36 PM To: amsat-bb Subject: [amsat-bb] 436CP42UG polarity switch update manual of M2 ???

Secret Word question
by James Luhn 14 Aug '11

14 Aug '11

I sent in a report to secretword(a)arissat1.org but I have not received a reply. I am just wondering if this is an auto reply response or does a real human look at the data? No big deal as the fun of hearing ARISSAT-1 far exceeds the desire for any kind of pdf certificate. I attached a recording that I made and perhaps this upset something. I am becoming quite attached to this satellite and do not miss any opportunity to receive a radio transmission. 73, James W5AOO.

All, By popular demand we are going to be running a Chicken Little Contest for ARISSat-1. Using the method of your choice, give us your best guesstimate of when it will finally reenter. One submission per person, class, or club, please. Alan WA4SCA ==================== AMSAT is happy to announce the ARISSat-1 Chicken Little Contest. This is your opportunity to calculate, or guess, when ARISSat-1 falls out of orbit. This is defined as the time it crosses an altitude of 78 kilometers, which is considered to be the point of no return. While not part of the contest, the actual reentry may be visible depending on location. Reports are encouraged. As in the past, we will have three divisions: + Student category for Kindergarten through grade 8 + Student category for High School, grades 9 through 12 + All others will be in the adult category. In addition to individual students, we encourage classes or organ- izations such as science clubs to make group submissions. Submissions are limited to one per person or group. Members of a group making a submission may not submit a second, individual entry. + Adults and individual students should include their name and amateur callsign if they have one. + Individual students should also give their grade in school. + Student groups should include the name of their group or class, school, and which category they represent. + Please give the UTC date in the format of day, month, year, hours, minutes, and seconds. + Finally, we would like to know your city, state, province or region, and your country. + Submissions will close on 15 September 2011 at 23:59:00 UTC. The closest predictions in each category will be recognized for their achievement. Send your submissions to CHICKENLITTLE(a)ARISSAT1.ORG. Good luck!

August 14, 2011 To All RADIO AMATEURS BID: $ANS-226.01 Hundreds of reception reports have been received since ARISSat-1/KEDR was deployed from the ISS. Full operational capability of the satel- lite has been confirmed in the 10 days since the start of the mission on August 3. The satellite's power system monitors the battery voltage and switches between High power mode (continuous transmission) when sunlight is charging the battery and Low power mode (40 seconds transmit/2 minutes idle) when in eclipse. Telemetry data shows that the ARISSat-1 Battery voltage is decreasing each eclipse period. It therefore is taking longer for the battery to charge up to 32.5V to allow the switch from Low Power to High Power when the satellite enters an illumination period. Kenneth Ransom, N5VHO has plotted the battery min/max for the last 8 days. The data shows that the battery voltage is decreasing at a faster rate than expected. Kenneth's graph can be found on the arissat1.org site under FAQ: http://tinyurl.com/3e5c2y8 (arissat1.org) The effect of this is that ARISSat-1/KEDR remains in Low power mode for a period of time after exiting eclipse. The team recommend that users take advantage of the High Power mode as much as possible over the next few days. 435 MHz - 145 MHz Linear Transponder - OPERATIONAL -------------------------------------------------- The linear transponder operates in Mode U/V (70 cm Up, 2m Down). It is an 16 KHz wide inverting passband. The convention is to TX LSB on the 435 MHz uplink and RX USB on the 145 MHz downlink. Several amateur radio operators have been reporting successful contacts via the linear transponder. After the initial success with the linear transponder reported by KO4MA, K8YSE, KD8CAO, and JN1GKZ last week news of addition contacts have been received from amateur radio operators worldwide: + Henk, PA3GUO uplinked an SSTV signal to the linear transponder and received the picture on the downlink.

Scouts Experience Successful ARISS Contact Scouts attending Space Jam 5 held at the Octave Chanute Air Museum in Rantoul, Illinois participated in an Amateur Radio on the International Space Station (ARISS) contact on Saturday, August 6. This was a telebridge contact via station WH6PN in Hawaii. Scouts put 18 questions about life in space to on-orbit astronaut Mike Fossum, KF5AQG. Over 250 Boy Scouts and Girl Scouts as well as 100 scout leaders attended the event. Besides the several merit badge workshops covering electronics, computers and others, activities included a balloon launch (with an on-board repeater) and a ham radio station, complete with satellite antennas. 2. ARISSat-1 Deployed ARISSat-1, an educational satellite that was developed by AMSAT (Radio Amateur Satellite Corporation) in cooperation with the NASA Office of Education ISS National Lab, Amateur Radio on the International Space Station (ARISS) and RSC-Energia, was deployed on Wednesday, August 3 during Russian EVA-29. The satellite contains an experiment developed by Kursk State Technical University students in Russia. Students and others may listen to ARISSat-1 to hear the 24 greetings in 15 languages (secret words included), to receive and decode spacecraft and experiment telemetry and to capture Slow Scan Television (SSTV) images.

August 14, 2011 To All RADIO AMATEURS BID: $ANS-226.09 ARISSat-1 Battery is Failing Faster than Expected The ARISSat-1 battery performed as expected during the first week of operation. Lower voltages during eclipse began to show up in the telemetry on 10 Aug 2011. The voltages during eclipse have continued to decline causing the satellite to reset and go into Emergency Power Mode on 12 Aug. After reset, the satellite MET (Mission Elapsed Timer) goes to 000, waits during the 15 minute TX delay, the power management software checks the current voltage and power values and determines what power mode to operate the satellite. The power mode is re-determined at fixed intervals, especially during illuminated periods to provide the most transmitted signals while protecting the battery. Additional information and explanation about the workings of the ARISSat-1/RadioSkaf-V power system can be found on the arissat1.org web site under the FAQ section. The ARISSat-1 team is closely monitoring the situation and is pleased with how well the power management software is controlling the battery usage to prolong the lifetime of the battery and the satellite as much as possible.

Hello all - I recently picked up an MMT 432/144 module for cheap. It seems to work OK on receive, but seems to have very low output on transmit. Does anyone have any manual or schematic type information for this unit? I think I have some debugging ahead and schematics, especially, might come in handy. Thanks, Ben

ARISSat-1 battery eclipse voltage decreasing
by Gould Smith 13 Aug '11

13 Aug '11

The ARISSat-1 Battery voltage is decreasing each eclipse period. It therefore is taking longer for the Battery to charge up to 32.5V to allow the switch from Low Power to High Power when the satellite enters an illumination period. Kenneth Ransom, N5VHO has plotted the battery min/max for the last 8 days. We see that the battery voltage is decreasing at a faster rate than expected. Kenneth's graph can be found on the arissat1.org site under FAQ http://www.arissat1.org/v3/index.php?option=com_content&view=section&layout… Take advantage of the High Power mode as much as possible over the next few days. 73, Gould, WA4SXM for the ARISSat-1/RadioSkaf-b team

ARISSat-1 Telemetry
by Greg D. 13 Aug '11

13 Aug '11

Hi all, Got a partial verbal telemetry this 04:08z pass (and a perfect preloaded SSTV). I think it said that the internal temperature was 45c. Isn't that a bit toasty? The next parameter I thought I heard 65, whatever it represents. Battery voltage was 36.09v, current -4ma. The satellite was in low power mode (40 seconds on, 2 min off), though I believe it was still in sunlight until right at the end of the pass. Sorry for the partial, but someone was on the phone and kept talking while I was trying to listen... Greg KO6TH

Batteries and High Power still working
by Luc Leblanc 13 Aug '11

13 Aug '11

>From www.arissat1.org >11 Aug 2001 >The Russian Silver-Zinc (Ag-Zn) battery that is powering ARISSat-1/RadioSkaf-B is the same battery that is used to power the Russian Orlan >space suits. The battery is designed for a lifetime of 5 deep charge-discharge cycles when used in the spacesuit. >Using it in a spacecraft going through 14 shallow charge-discharge cycles per day is new territory. 12 days since activation time 14 shallow charge-discharge cycles per day =168 shallow charge-discharge cycles "Is shallow = normal charge- discharge?" Some specs: Silver-zinc batteries are available off-the-shelf and have a higher specific energy (130 Wh/kg) and density (240 Wh/litre) than most other commonly available secondary batteries. High cost, limited cycle and shelf life, and a long recharging process reduce its overall attraction. While at normal discharge rates, 40 to 50 cycles can be expected from the battery, this reduces to 10 or 15 at high discharge rates. Cycle life is also reduced if the battery is discharged below 80% of rated capacity and thus, a 20% reserve is required at the end of the mission. Silver-zinc batteries have been used extensively in AUVs and their performance is reliable and documented. Their high cost and short life have, however, prompted consideration of alternative technologies. P.S.

ARISSat-1 over West Malaysia 13 Aug 2225 UTC
by Sion Chow Q. C. (9W2QC) 13 Aug '11

13 Aug '11

Dear All, ARISSat-1 was heard over West Malaysia during 13 Aug, 2225 UTC pass. The satellite was first heard in low power mode and subsequently it was in high power mode until LOS. A total of 27 telemetry frames were copied and forwarded, and subsequent replay of the I/Q recordings provided another 3 SSTV images and the following voice telemetry: MET - 10 min IHU Temp - +37C Control Panel Temp - +43C Battery Voltage: 35.58v Battery Current - -16mA (discharging) MET - 12 min IHU Temp - +37C Control Panel Temp - +43C Battery Voltage: 35.74v Battery Current - +4mA (charging) This was the 2nd pass using the FCD with DK3WN's Doppler Control for FCD + HDSDR + ARISStlm for automated copy. The FCD is a simply amazing piece of hardware :) 73, Sion Chow Q. C., 9M2CQC Also: WQ2C /HL1, 9V1QC, JG1XHM, ex: 9W2QC, AB3IO

Help with Yaesu FT-736R fault
by Ron Taylor 13 Aug '11

13 Aug '11

Hi Folks, Hoping someone may have some ideas on a fault that has just developed in my FT-736R radio. The multi function S-meter has decided to quit on me. It does not indicate in either receive, transmit, diiscriminator/ALC or any other position of the meter selector switch. The radio though, still functions perfectly on both transmit and receive - with no indication of any degradation in sensitivity or transmit output power. I will be pulling it to bits, but thought I'd first check to see whether anyone has come across this particular fault. The radio was bought new in the '90's and I have fixed one fault in the power supply about 10 years ago. Many thanks for reading this. 73, Ron Taylor - VK6TF Perth, Australia.

Portable FM18 Earlier Today
by Patrick Farcon 12 Aug '11

12 Aug '11

All: Thanks to all that I was able to work from Washington, DC. I have worked many new grids from many stations that have gone portable and I thought it a great opportunity to give back and hopefully even perhaps offer FM18 as a new grid for someone. I worked the 20:27 UTC pass from here with 2 HT and an Arrow II. It fit the mini vacation schedule well and was an 81 or so degree pass at peak so since I don't work portable often I figured that would be my best opportunity to be successful. I hope to be able to offer other grids in the future on other trips. 73, Pat Farcon N2VYT portable in FM18

1000 baud telemetry showing Clock has been reset Last frame 1565 seconds Voltage 35.549 LOW POWER >From memory copied 8 frames from AOS then it went off (low voltage). When it came back on the 1000 baud sounded very raucous and was difficult copy, just 2 frames. CW copy was good. 73 Colin VK5HI
