Fw: AO73 Mode change
by Graham Shirville 11 Jun '19

11 Jun '19

Hi folks, AO73/FUNcube is now in amateur mode for the weekend with the transponder on! Please see below for all FUNcube mission info 73s Graham G3VZV and the FUNcube team. ++++++++++++++++++++++++++++++++++ FUNcube frequencies and other details ++++++++++++++++++++++++++++++++++ AO-73 FUNcube-1 The transponder is normally operational only when the satellite is in eclipse, ie the solar panels are NOT being illuminated. During weekends (from pm Fridays UTC to PM Sundays UTC) the transponder is operational 24/7. When the transponder is switched off, the telemetry beacon is on full power, when the transponder is on the beacon it is on low power. During holidays, eg Christmas, New Year, Easter, etc, the transponder maybe activated for extended periods. Watch AMSAT-BB for announcements which are usually made on Friday evenings (UTC) The nominal transponder frequencies are: Uplink: 435.150 - 435.130 MHz LSB (Inverting) Downlink: 145.950 - 145.970 MHz USB Telemetry Tx: 145.935 MHz BPSK (The passband may be up to 15kHz higher depending on on-board temps. Lower temperatures give higher freqs!) FUNcube-2 (aka FUNcube on UKube) The FUNcube-2 sub-system continues to operate autonomously and, almost continuously, in amateur mode. The transponder is operational and the telemetry downlink is functioning with about 70mW output. The FUNcube-1 Dashboard does not correctly display the telemetry but it does correctly decode the data and uploads it to the FUNcube Data Warehouse from where it can be examined. Most of the real time data channels are operational and these include battery voltages, temperatures and ADCS data coming via the main On Board Computer (OBC). The transponder is interrupted for a few seconds every 2 minutes when the other transmitter sends its CW beacon and, occasionally, for a few seconds when the main OBC reboots (approx seven times each orbit). The nominal transponder frequencies are: Uplink: 435.080 - 435.060 MHz LSB (Inverting) Downlink: 145.930 - 145.950 MHz USB Telemetry Tx: 145.915 MHz BPSK (The passband may be up to 10kHz higher depending on on-board temps. Low temperatures give higher freqs!) EO79 FUNcube-3 Due to power budget constraints the transponder cannot be operational 24/7 and an orbit specific schedule has been developed. The transponder will commence operation 27 minutes after the spacecraft enters sunlight and will stay on for a period of 25 minutes. This schedule may be modified in future months as a result of experience. The nominal transponder frequencies are: Uplink: 435.0723-435.0473 MHz LSB (Inverting) Downlink: 145.946-145.971 MHz USB Further detailed info on EO79 transponder frequencies is at: https://amsat-uk.org/2016/11/10/eo79-funcube-3-transponder-commences-regula… EO88/Nayif-1/FUNcube-5 EO88 is presently operating in autonomous mode. The transponder is operational when the satellite is in eclipse, ie the solar panels are NOT being illuminated. When the transponder is switched off, the telemetry beacon is on full power, when the transponder is on the beacon it is on low power. The transponder frequencies are: Uplink: 435.045 – 435.015 MHz LSB (inverting) Downlink: 145.960-145.990 MHz USB Telemetry Tx: 145.940MHz All FUNcube transponders are sponsored by AMSAT-UK and AMSAT-NL.

EQUiSat Optical Beacon CubeSat
by Trevor . 17 Oct '18

17 Oct '18

Students at the Ivy League Brown University are developing an amateur radio satellite EQUiSat that will carry a Xenon Flash Tube (XFT) subsystem to act as an Optical Beacon that should be visible to the unaided eye of observers on Earth.

Using 1.2Ghz
by Todd 04 Apr '18

04 Apr '18

Thinking about adding the 1.2Ghz module for my 9100. Prices have dropped a little and units will start become harder to find once production ends. Anybody using this band? I read it's used as a uplink frequency for some satellites. Any input appreciated.ToddAL7PX

Outernet L-Band now carries AMSAT and ARISS weekly bulletins
by Robert Bruninga 17 Mar '18

17 Mar '18

The Outernet L-band feed is now carrying a condensed version of the AMSAT and ARISS weekly news files. (Global Geosat coverage except for Northern Alaska)... Receivers are simple: http://aprs.org/outnet.html For ARISS, I manually added a 2 char grid square to each school listed in the school schedule and am asking the outernet folks to parse out that location info and plot a 1200 km footprint on their weather globe showing where people can tune in the ARISS contacts. Then their RTL-SDR dongle could then actually be retuned to hear the contact. Just an idea...

TUning the antennas on a Cubesat
by Robert Bruninga 02 Oct '17

02 Oct '17

Someone asked me how to tune the antennas on a cubesat without the instrumentation totally becoming part of the antenna system itself? I said you have to put the SWR instrument inside the cubesat as we did here: http://aprs.org/PSAT2/SWR-testing-0160x.jpg But that only works on a 1.5U cubesat where and MFJ Antenna Analyzer will fit! The other method is to just put in a bidirectional coupler chip, and then feed the forward and reflected voltage taps to the internal cubesat telemetry system and then compute the SWR from these two Forward and Reflected power telemetry channels.

Re: [amsat-bb] WISP replacement? (or Live digipeating?)

It was possible to enable digipeating in a PACSAT protocol satellite. I wonder if it should be considered? I know I'd like it... ;-) Live Real-time satellite operations. I remember 20 years ago, I worked for a month and finally got a PACSAT ground station to work. Did one pass. Once I saw that it was a hands off, automatic process, with nothing to do during the pass but just watch it work, I lost interest and never went back... I wanted something live... Bob, WB4APR.

Road trip Texas => Utah
by Glenn Miller - AA5PK 01 Oct '17

01 Oct '17

On Monday, 18 September, I'll be starting a leisurely road trip to Utah. Monday night will be spent in DM73 in NM and Tuesday night in DM57 in CO. Destination is DN41. I will operate the sats from those three grids. I also hope to work from other grids en route, depending on available passes. Possible grids are DM74, DM75, DM65, DM66, DM58, DM48, DM49 and DN40. None are extremely rare, but newer grid chasers may need some or all. While in Utah, I'll try to activate some grids surrounding DN41. If interested, follow me on twitter.com/@AA5PK for updates and track me on APRS at AA5PK-9. All QSOs will be uploaded to LoTW upon my return home. Hard copy QSLs by email request. 73 Glenn / AA5PK

NON-AX25 response from Falconsat-3
by Fernando Ramirez 30 Sep '17

30 Sep '17

Good afternoon! I tried a Falconsat-3 pass today using a FT-817nd, a Signalink interface and my laptop running HDSDR, UISS and HS Soundmodem. The 817 is set to work as my transmitter and a SDRPlay RSP1 as receiver. I was able to decode several packets from the satellite, including some from WD9EWK. When I tried sending location or messages using "CQ to PFS3-1" never saw my packets digipeated, only a: <NON-AX25 frame Len=24> Anybody knows what I could be doing wrong? Thanks Fernando, NP4JV

Yaesu FT-736r for sale
by Al Sawyer, K9ILF 28 Sep '17

28 Sep '17

Our radio club is selling a Yaesu FT-736r with hand mic, and DC power cable that we received from a donor this year. The rig is equipped with four modules: 2 meters, 220 MHz, 440 MHz, and 1.2 GHz. The rig also has installed the FTS-8 tone board and FVS-1 voice synthesizer. Our club's main satellite operator has tested all these and found them to be working. The donor was fastidious and packed the rig back in its original box with the manual when he retired it from use. We are asking $1100 for sale in the US only. Please contact me for details or photos.

Looking to move my two mast mounted preamps into an enclosure. Who knows of a good mast mounted waterproof enclosure that will handle 2 Advanced Recv'r 160 Watt Mast Mounted Amateur Preamp's inside? The preamps are 5" wide and 2-1/2 deep. I could stack them on top of each other or side by side. Let me know if the suggested enclosure will have the hardware to mount to the mast. Provide me with links to the items. Thanks. Steve NS3L

EM94 & SC Friday evening SO-50 & FO-29
by Kevin M 28 Sep '17

28 Sep '17

Barring the unforeseen, I plan on riding down to Rock Hill SC Friday evening with KM4VDM and fulfilling a request from a friend to operate from EM94. I will also be in South Carolina for those that may need it for their Satellite WAS. This will be two passes only, one on each sat. SO-50 at 0209z (Sat UTC time) and then about twenty minutes after that pass, FO-20 at 0245z (Sat UTC time) Most likely will be in the lower half of the RX passband (145.970 uplink) unless there is QRM or other issues. I should have access to twitter during the trip, so updates as we go and then lotW upload after returning home a few hours later, paper QSL by request. 73, Kevin N4UFO

Waterproof mast mounted preamp enclosure?
by Steve Nordahl 28 Sep '17

Looking to move my two mast mounted preamps into an enclosure. Who knows of a good mast mounted waterproof enclosure that will handle 2 Advanced Recv'r 160 Watt Mast Mounted Amateur Preamp's inside? The preamps are 5" wide and 2-1/2 deep. I could stack them on top of each other or side by side. Let me know if the suggested enclosure will have the hardware to mount to the mast. Provide me with links to the items. Thanks.Steve NS3L

Jack - I use just a TM-V710, and can get in just fine. I still am having issues getting the TNC to operate in full duplex, but am working on a solution. --Roy K3RLD

FalconSAT-3 ???
by Jack Chomley 28 Sep '17

28 Sep '17

Hi Everyone, Newbie on this list, but I may have been here 20 years ago :-). Back in the last millennium I was an Oscar 16 geek and was very active on it. Since it's gone, I have not seen another Sat with similar operating parameters, until FalconSAT-3 came along. Naturally, my old PSK-1T tnc and radios are no good, not to mention my DOS box with PB and PG on it. So, my question is.......what are people using to operate on Falcon SAT-3? I have a WIN7 box, a Timewave Navigator, SignaLink USB, FT-817 and TM-D710 radios. Is any of this useful to get going with? Any ideas, software suggestions etc, appreciated :-) 73, Jack VK4JRC Club. www.cqara.org.au
