[amsat-bb] PSAT2 PSK31 transponder operation

[Brad Schumacher]

I have been able to activate the PSK31 transponder with as little as 20
watts when the satellite was at TCA and about 80 watts when closer to the
horizon.  

 

I am using a Zero-Five 10-40GP vertical antenna which is about 27 feet in
length.

 

I learned that the PSK-31 will continue to run even when the SSTV is active.


If the PSK-31 receive audio is kept between about 500 Hz to 1000 Hz and
above about 2500 Hz it will not get interfered with from the SSTV
transmission. In other words, set the 10 Meter uplink between 29.4785 and
29.4790 or between about 29.4805 and 29.4810 to stay out of the SSTV audio
range. 

 

Thanks
