More Satellite RX
With my CAT interface setup (along with hamlib’s rigctld and gpredict feeding the Doppler data) I’ve begun trying out more satellites.
Today I heard:
- AO-51 voice repeater
- CO-57′s CW beacon
- HO-68′s CW beacon
- COMPASS-1′s CW beacon
- CO-65′s CW beacon
- RS-22′s CW beacon
Satellites I tried but did not hear
- O/OREOS’s packet
- SO-50′s FM repeater
- FAST-1
- CO-65′s packet
- UWE-2′s 1k2 packet
- ITUPSAT 1
- BEESAT
I’ve noted that on these passes I’m still severely limited to the north/northwest due to building layout. I’m considering the following to help:
- Extend my antenna mast a couple more feet (and add guy wires to improve stability)
- Trying out some preamps like the Ramsey PR100 (2m) and PR40 (70cm)
I’ve also noticed that when I’m in CW,CW-R,LSB, & USB modes I hear clicks associated with the CAT interface, which is sending new frequencies at a configurable rate (gpredict’s default is 1Hz, I’m using 5Hz successfully, but the clicking does correlate with there rate). Changing the CAT baud rate from 4k8 to 9k6 or 38k4 doesn’t seem to make a difference.
