Programming SatPC32 Doppler SQF to put IC-9100 into USB Data mode?
by hdskullfire2 . 17 Feb '17

17 Feb '17

Looking for information on programming SatPC32 Doppler SQF strings to put a Icom IC-9100 into USB Data mode? I know already that FMD works fine for FM mode, but I can't find any way to get it into USB/LSB data mode without turning off cat control which would revert it to normal mode as soon as a doppler update is sent..

Just worked KO6TH on the 19:40 utc 17 Feb 2017 pass over Western USA. This will most likely be the last opportunity on this satellite. It has been a good satellite. KO6TZ BOB

AO-73/FUNcube Mode change
by Jim Heck 17 Feb '17

17 Feb '17

Hi folks, I have just changed the sat into amateur (continuous transponder) mode. Plan is to switch back to auto mode on Sunday 19 Feb 2017 pm UTC as usual. See https://funcube.org.uk/news/ for details of new FUNcube launched a few days ago, and Pls see below for other FUNcube transponder info Have FUN with the transponder. 73s Jim G3WGM and the FUNcube team. 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. Low 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… All FUNcube transponders are sponsored by AMSAT-UK and AMSAT-NL. We are very grateful for the assistance given by Innovative Solution In Space Bv, The Netherlands.

BY70-1 re-entry
by Tom Schuessler 17 Feb '17

17 Feb '17

I would have to think that when the satellite does re-enter the atmosphere it will be in the southern hemisphere because it's Parigi is down there. Tom Schuessler. N5HYP
