Hi, having low signals level with Satnogs/RTL-SDR. Even passes with the NOAA sats show barely anythings on the waterfall.
Satnogs RF gain is set at 32.8. Antenna Diamond X30-N, cable 6m RG213. Lots of signals running the RTL-SDR with SDR++ so hardware seems ok.
SoapySDRUtil --probe is not working “command not found”
this somewhat compensates for weaker signals on the horizon and stronger overhead. but they’re often quite deaf to signals at high elevation angles.
it is also not made for 137MHz, so the gain and pattern at that frequency is probably unknown.
Hi SA2KNG,
Thanks for the response. Had the idea that NOAA sats would give signals that could be read with less than perfect antenna’s. But seems this is not the case. Considering that, the whole Satnogs thing is imho only interesting for some lucky ones with dedicated tracking antennas. Pity this is not mentioned in the wiki’s…
I think there’s some stats for this, but it is not at all some minimum requirement.
Jan, myself and many others have put a lot of work in their (stationary antenna) stations and the results speak for themselves.
Example of observations with data uploaded on my station 1864
Getting a station up and running is pretty much the first step. Improving reception by experimenting with antennas, filters and preamps is what starts then and there, and many enjoy this part immensely as it can be very rewarding.
