Thank you Arrow Antenna for just becoming a sponsor of Space Comms! I
still have my original Arrow II satellite antenna from 2000 and I
highly recommend them.
Thanks to Dog Park Software for the usage of MacDoppler and
MacLoggerDX, sorry for forgetting to include you in the end credits.
Thank you of course to Victor for doing the translation. It was a lot
of fun working with you. Thank you to Phillip Zucchino at The Wine
Feed for hooking me up with SKEMA, and Marie Claire at SKEMA for
hooking me up with Victor.
Thanks to Max, K2MAX for recently becoming a patron. Good luck working
satellites from the San Francisco bay area where you won't have many
obstructions on the horizon.
Thanks to Frank for the drone footage.
And thanks to you for watching!

Hi All,
FUNcube-1 is now in amateur (continuous transponder) mode. The plan is to
switch back to auto mode on Sunday 5th March 2017 pm UTC as usual.
See https://funcube.org.uk/news/ for the latest details of Nayif-1/EO88 and
new updated Dashboards. Please also see below for details of all the FUNcube
spacecraft.
Have FUN with the transponder!
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. 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-regular-
operation/
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. We are very
grateful for the assistance given by Innovative Solution In Space Bv, The
Netherlands.

One thing to remember is that you cannot use normal Doppler correcting
software that tunes the radio.? The instantaneous radio steps cause Phase
discontinuities and that completely destroys PSK31.
The only ways to work well is to only try to decode when the bird is coming
right at you or right aways from you and the Doppler is not rapidly
changing.
*** OR *** use the special PSK31 Doppler uplink correcting program written
by Andy Flowers found on the PSAT web page? http://aprs.org/psat.html
Here is his page:
http://www.frontiernet.net/~aflowers/dopplerpsk/dopplerpsk.html
This software also allows you to run full duplex so that you can uplink
continuously throughtout the pass and independently receive all downlinks
at the same time.? The radio does not tune, but your uplink audio
compensates for the uplink Doppler so that your trace in the downlink
appears constant to everyone.
Yes, you can run UHF Radio stepped Doppler correction that steps down in
the usual 5 KHz steps 4 times during the pass.? You may still loose an
instant of phase corrupted characters, but only 4 times, not every few
seconds as the SSB radio would try to do if the computer program was trying
to compensate the SSB uplink radio.
That help?
Bob

On a positive note, APRS is working perfectly on NO84 even at low passes.

I'm not getting what you mean? EO-80 is an FM transponder, EO-88 is a linear

EO-80 and EO-88 have similar names. Simply based on that, seeing one
might remind you of the other.
Perhaps that wasn't it though...
Regardless, the answer to the original question is on amsat.org
"Additionally, the satellite carries a AMSAT-F constructed repeater as
a return favor for support of the use of the amateur bands for the
primary QB50 mission. Unfortunately the primary transceiver was
damaged during a test of the repeater, and the repeater is power
negative. Further activation of the repeater is unlikely at this
time."

OK, tonight on the high pass at 0300 UTC over US East Coast, I heard the
following with my IC910H tuned to 435.350 MHz FM-Narrow, feeding FLDIGI
through a SignaLink USB card:
1. W3ADO beacon. The beacon signal was so strong it was almost like
hearing an FM repeater that is "full quieting" with no background noise at
all.
2. Someone transmitting early in the pass, but Doppler was moving the
signal and I did not decode it because it eventually went right on top of
the beacon.
I attempted to transmit using DopplerPSK, 50 watts to an inverted L, but I
did not see my signal on the downlink at all. I measured 50 watts output,
and I listened on a separate receiver (no antenna) on 28.120 and I did hear
PSK.
Questions:
* I am using TS480SAT for transmit. I have the dial on 28.120, which
means that the center AF frequency is 2 kHz according to Doppler PSK. Is
that correct for the dial frequency?
* Any other suggestions on what I should do, or just try again on the
next pass?
