WD9EWK AO-51 V/S, Sunday 3 Sept.
by Patrick STODDARD (WD9EWK/VA7EWK) 03 Sep '06

03 Sep '06

Hi again! Another day, another chance (or two) to make more V/S QSOs via AO-51 before the mode change. I woke up a little early this morning, so I decided to combine a quick shopping trip with a trip to a nearby city park that sits on the DM33/DM43 boundary. I was on the AO-51 pass around 1550-1600 UTC from the park with my portable V/S setup, and made 7 QSOs. The most activity I've heard in the 5 AO-51 passes I've tried since Friday. I worked W0LMD (CO), KU7Z (UT), N8BBQ (OH), W2NBJ (MD), KB0JQO (IA), WA4SCA (TN), and AI7W (OR). On the next pass, around 1730 UTC, I was back home and worked W0LMD and KU7Z again - the only ones on there with me. I was in the driveway in front of my house, using the car as my base of operations again. For much of the pass, I left the 2m Yagi laying on the car's roof and took the downconverter in one hand to point and twist it. AO-51's 145.920 MHz receiver is very sensitive, even when my Yagi was pointing parallel to the ground and the satellite was up at 20-30 degrees elevation. Assuming the mode change happens tonight (early Monday, UTC time), this will be the last chance to try V/S for a little while. I made 14 contacts on 5 different passes. I worked two stations on each of 3 passes (W0LMD, KU7Z), and those stations were in 10 different states. When I grow up :-) I would like to set up a proper satellite station at home. Until then, I am happy to be able to set up portable stations and do this stuff. Fun stuff, even if it is 95F/35C outside at the moment. 73!

WD9EWK and AO-51 V/S, Saturday (2 Sep) morning
by Patrick STODDARD (WD9EWK/VA7EWK) 03 Sep '06

03 Sep '06

Hi! I took a short drive to a nearby park that straddles 112 degrees West longitude (the DM33/DM43 boundary), and set up for a low western pass for AO-51 around 1808-1818 UTC. Maximum elevation was only 10 degrees, but I wanted to give it a try with my portable V/S setup I've started using. No contacts, but I know I could hear the S-band downlink from about 4 or 5 degrees elevation from that location. I had a lot of time to talk to myself. :-) An impressive thing, the AO-51 S-band downlink. Very easy to hear even at low elevation, and I'm hoping to try at least one pass tonight and one Sunday morning before the mode change. 73!

Icom 910 Aux Switching
by Bruce 03 Sep '06

03 Sep '06

Keith With the help of K5VH I was already working on your question of aux switching the 910. I'am working towards using my 70 watt amp for TX L-band. Per Toms help I am using a reed relay from radio shack & perf board. I was successful in using the ACC socket, pin 2 & 3 to switch the relay on & off, controlling 12V to my 1270 Mhz amp PTT. Works great when you key the mike & with Wisp it correctly TX's my TNC & 1270 amp automatically. 73 Bruce KG4YEV

Graphical satellite calendar
by John Mock 03 Sep '06

03 Sep '06

Here's a work in progress: http://www.qsl.net/kd6pag/Sep2006.gif This shows graphically when passes for SO-50 and AO-51 occur at my QTH for the month of September. Each row corresponds to a day, each square is an hour, and the colored rectangles inside a square (or two) represent a given pass, with the color corresponding to the satellite listed in the legend. The height of the rectangle corresponds to the maximum elevation of the pass. If a rectangle is at the top of a square, then it's largely an eastern pass, and if at the bottom of a square, then it's a western pass. If it's not quite at the top or bottom, then the maximum elevation is not exactly in the east or west; for example, if AOS is in the north and LOS is in the east (instead of the south). So one can quickly glance at the graphical calendar and see which are good passes to try to work in the next few days. It may also be helpful for rovers when planning trips, to maximize the number of passes while in a given area. Spouses who might not be able to read satellite predictions could look at the graph and have an idea of when you might want to be busy. So far, the predictions are generated using LINUX SatTrack (perhaps edited by hand, for example, to account for AO-51's schedule) and fed into a Perl program which produces the .gif files. Eventually, i'll probably make it CGI accessible if folks find it useful. Let me know what you think. 73's and good luck. -- KD6PAG (Networking Old-Timer, Satellite QRPer)

Hi I wish to switch my amp and pre amps when using the Icom 910H Is their any way of having a switching line the changes when the rig goes into TX I have read the manual and checked the sockets on the back of the rig but can't see an aux switching line or voltage change or anything that I could use.

Re: Icom 910H aux switching
by Scott Townley 02 Sep '06

02 Sep '06

Keith: My 2 pence worth is that the best way to do these things is with an external sequencer. The ARRL Handbook has a simple one, plus you can get them ready-made from DB6NT, Advanced Receiver Research, and I think W1GHZ sells some on eBay from time to time. The idea: you PTT the sequencer (footswitch or equivalent) and the sequencer unkeys the preamp, keys the amp, and then keys the rig, in that order. That way everything is where it should be when you speak/key the rig. If you have the rig put everything else in TX then the rig can be transmitting before/as the relays are switching over, which is a guaranteed way of replacing your preamp transistors and/or relays someday. That also implies no VOX with preamps.

WD9EWK's first time on AO-51 V/S tonight
by Patrick STODDARD (WD9EWK/VA7EWK) 02 Sep '06

02 Sep '06

Hi! I've had an AIDC 3731 downconverter, one converted by K5GNA, for just over a year. I haven't used it until tonight, when I had some free time in the evening. I took it and a bunch of stuff to my stepson's Boy Scout meeting (a church in grid DM43ap, northeast Phoenix), and hoped to work an AO-51 pass while he was in his meeting. After a storm blew through Phoenix (it kept me off an SO-50 pass around 0220 UTC), the skies cleared enough to make a try at the AO-51 pass around 0320 UTC. I set up my station, and waited for the satellite. TX was my IC-W32A HT at 5W, turning off the 70cm side of the radio, into my Arrow Antennas 2m/70cm handheld Yagi. RX was with the downconverter into a Yaesu VX-2R (I could disable TX on this radio, to protect the downconverter - plus it had an attenuator). I had a 6dB attenuator in the coax line, along with the VX-2R's attenuator function, so the S-meter wasn't moving much until I heard the satellite. Once I found the downlink, it wasn't hard to keep up with it through the pass. I let the downconverter with its dipole and corner reflector sit on the car's roof, and had a splitter from the VX-2R's speaker-mic jack to feed an earpiece and my Sony digital recorder. I heard one QSO finish up, then I made a call. Angelo N5UXT in New Orleans heard me and I worked him first, then I was called by WA4EWV. I heard a W9HT toward the end of the pass, but could not work that station. I could follow the Doppler on the RX signal well enough, and every so often the signal would take a dip and then come back up. If I held the downconverter and twisted it, I could get the signal back up, but most of the time I just set it on the roof in the general direction of AO-51 and held the Yagi in one hand and a speaker-mic into my IC-W32A with the other hand. I really wish I had a small camera or camcorder with me, to get a photo of my "station", but at least I have an audio recording of the pass with my 2 contacts. I am impressed with how well the downconverter worked, and with AO-51 in this V/S configuration. This was the first time I did anything that used a ham frequency above 23cm. I'm hoping to have some time Friday morning to work an AO-51 pass and try this again, but if that's not possible I want to work some passes this weekend before the mode change. This was fun! 73!

Hi to the list, due to change the antenna cables, I would like to know which is the better one at least price For the Satellites activates. Unfortunately I have to use a long descent. I want also install my old 23 elements antenna for the 1,2 GHz. So the cable should be all for the satellites activates and should be for 2 meters 70 centimetres 23 centimetres I would like also to get a Mast preamplifier for the 23 centimetres. I already have the Mast preamplifier for the 2 meters and the 70 centimetres. They are both from Dressler and both has the EVV Interface. Please let me know which one is the better one at least price and if it needs also of the interface. Please let me know prices and where to get them Any suggestion will be really appreciated.

ECHO
by McGrane 01 Sep '06

01 Sep '06

greetings I would like to report very poor reception of echo even with an 8 element yagi and an 18 Db preamp. I assume the downlink power is real flea power for battery charging or other testing. After 2 years of pleading with amsat, the downlink power is still a mystery. It is not shown on the colaradosatellite telemetry graphs (TX B) or the amsat website, after repeated requests here and elsewhere I'll assume it is being held secret for some reason. There has been a tremendous lack of technical reporting on ECHO. I realize people are very busy but time should be taken to educate the amsat community. 73, patrick N2OEQ 32323

Last call for instock 2.4 GHz downconverters
by k5gna＠houston.rr.com 01 Sep '06

01 Sep '06

To: All, from Bob, K5GNA Please respond to: k5gna(a)aol.com -- replying to the Road Runner address on this Email will only delay a response. I have Fourteen (14) of the AIDC 2.4 GHz downconverters packages left that are packed and ready to ship, except for sealing. I have shipped a lot of these downconverters in the last few years, but I am not restocking these downconverters until we have another HEO satellite up, or if there should be enough demand (enough on a waiting list) for 2.4 GHz receive in the near future. THIS MAY BE YOUR LAST CHANCE TO GET ONE FOR A WHILE. These packages include about everything you will need to receive AO-51 for portable or even fixed operation, except the FM receiver and battery. The package will include the following: AIDC 3731 downconverter with 37 dB of gain, good for 13.8 VDC operation, retuned for 2.4 GHz, with a 2 meter IF crystal @ $105.00; 12 dBi corner reflector @ $27.00; Power inserter @ $10.00; 6 dB attenuator @ $3.00; 3' and 12' jumper for portable operation @ $5.00; F female to BNC male adapter @ $3.00; Shipping, handling and insurance in the USA @ $10.00. TOTALl = $163.00 SHIPPING OVERSEAS WOULD ADD AN ADDITIONAL $20.00. Just for the AMSAT BB -- I will also include the following 2 items at NO CHARGE: (1) N adapter for future use with a larger dish and feed (normally @ $ 5.00) (2) Wall wart power supply with weird connector -- simply cut it and splice it into a short F cable -- but since it is 110VAC, it is not for overseas. (normally @ $5.00). The remaining units not taken on the Amsat BB will go on Ebay in few days, but without the 2 giveaways. I also have some 2.4 GHz signal sources for $17.50, plus $8.00 shipping and handling in the USA. These are Gardiner downconverters that without modifications will produce a signal at about 2399.875 MHz (or 143.875 MHz in your RX). I also include a crystal (solders to the top of the PC board) to come out at about 2400.020 (or 144.020 MHz in your RX). I have a few of the 12 dBi corner reflectors that clip onto the AIDC downconverters available separately at $27.00 each plus shipping and handling. I could also add the signal sources to the downconverter packages, plus I could replace the 12' portable sized cable with a 50' cable for fixed use -- please inqure. Please respond to me at k5gna(a)aol.com if you want someting and I will send you complete details on paying, etc. Bob K5GNA k5gna(a)aol.com

Hi all On my lunch break i was able to make a QSO with VE3BSB James in his car running. It was my first QSO with a mobile station on a Transponder type satellite in SSB. I was testting an old KLM 2M 14C on the downlink and i was using a 7.5' dish on the uplink. The power setting was at 0 on my FT-847. The hic with low TX power make us often unhearded by some stations and i have to often crank up my power to be able to make the other party hear me. But on this QSO i was able to keep my power at 0 or near that as the 847 still transmit some wattage my last preamp knows it...

ECHO duty cycle
by McGrane 01 Sep '06

01 Sep '06

hello again- Does anyone know what percentage of a day or orbit the echo transmitters are ON? I've been thinking about the battery depth of discharge issue. Being that they are as a whole 4 amp hours, a 10 percent discharge would equate to about 1.6 amps for one quarter of an orbit on-time. According to drew, the transmitters are drawing about .8 amps. I hope people are viewing depth of discharge as a function of amp-hours more than voltage ( I realize also important ). Any comments are welcome. Thanks, pat n2oeq

Re: Digital sats with less
by Gould Smith 01 Sep '06

01 Sep '06

Hi Gary, Yes the USB to serial adapters work, but they are not all equal. I have found the ones with the FTDI chip and drivers to be the most reliable. In my computer upgrade I installed a USB to serial port and also got a PCI to dual serial port card (very cost effective). The new computer came with no serial ports, but I am using three serial ports for digital work. First one for 9600 bps modem to WiSP software. Second for SatPC32 to LVB tracker and rotor control Third for SatPC32 to FT-847 for Doppler tracking. Granted, I had to install/uninstall theUSB/serial driver about 8 times before it worked. The PCI card with two serial ports worked the first time.
