That's an interesting observation Jerry. Not something we saw during
commissioning the satellite.
A possible cause would be image response of the dongle. Do you have the 'zero
frequency' somewhere between the beacon and the transponder passband? e.g.
145.945 or off to one side e.g.
Some weeks ago I saw Italian stations running vast amounts of power through
a transponder and causing the beacon to modulate heavily, can't remember
which satellite it was.
In fact these stations were running so much ERP that they took the entire
satellite out.

Twelve CubeSats are set to launch aboard an Atlas V rocket with the NROL-39
primary payload from Vandenberg AFB in California on December 5, 2013. The
CubeSat payloads have been provided through NASA's Educational Launch of
Nanosatellites (ELaNa) program and the NRO's Mission Integration
I have two BOAFANG (SP?) that the club want to program for SO 50. and
possibly in advance for FOX 1. (I know that SO 50 has a tone.)
The questions:
* What freq should be programed for S0 50 to comp for Doppler?
* Same for FOX 1
Thanks everyone for their help.

Rich,
The answers to most of the questions you have been asking lately could be
found if you search the BB archives.
Here is a link to Clint's how to for SO-50 frequencies.

To use the two Baofeng radios on SO-50:
1. Program one memory channel for 145.85 MHz with a 67 Hz tone.
2. Program another memory channel for 145.85 MHz with a 74.4 Hz tone.
This channel will serve to turn on the 10-minute timer when required.
3. Next, program a set of memory channels
Good thought, David. I do have the settings FCD Centre Frequency set
for 145945. But I also have the auto tune range limited to 34599-44854
kHz which should only let the auto tune catch approximately 145931 to
145941 kHz. So it should not be (nor do I observer it to) tuning any of

Is there a reliable way to predict what status the transponder on AO-73
will be on a given pass over the US? Perhaps a web page that I missed?
Any help appreciated.

I also observed something like this the other day. I wondered about its
cause, but as I was actually doing something else at the time, I
completely forgot about it.
There were, as you note, strong SSB signals around the beacon freq
during the AO-73 pass.

I use PCSat32 with two radios, an Icom IC7000 for 2m and a Yaesu FT-857 for
70 cm. (I use this particular setup because the FT-857 doesn't respond to
the tone settings when in FM mode on SO-50)
This seems to work, it correctly assigns selects the proper radio for uplink
or downlink and band.
Thanks

the program supports the sub tone function of the FT-857 for woking SO-50.
If you configure the Icom as Radio 1 and the FT-817 as Radio 2 the 817
will transmit on 2m with FO-29, SO-50. Choose SO-50 and click the control T
to T1 or T2. A little T will appear in the display. The program

Hi Roland.
Nice data from CAPE-2.
Curious about the unregulated bus voltage around 5.2V.
Doesn't seem to fit with a single or double Li poly cell. However, if it's the
output from 2 series solar cells, that might indicate the batteries are fully
charged and we are seeing the max power
Congrats to the team...

I will have an AMSAT table at the Superstition Amateur Radio

This hamfest is at Schnepf Farms in Queen Creek, a town

Yep I'm definitely hearing stations again tonight, even with the preamp
off. It may be an image, I can see the same QSO up higher on the
spectrum display at about the same offset from the center frequency
145945 so that would make it about 145957 or so (give or take late night
calculating)
