Configuration for VHF/UHF station with two SDRs

Hi,

Since I have a VHF antenna at my station, I’d like to add it to the network as well. However, it is rotated by the same rotator, and it is attached to a second (remote) RTL-SDR. What is the proper way to set up the stations for dual-band reception, with one of them having priority over the other? Maybe same client, but uses different SDR for each band? I don’t know if it’s supported.

do you mean you have two antenna vhf and uhf? or you using single antenna vhf?

btw satnogs support more than one sdr, in one machine (raspberry / sbc / pc) , and running more than one station

The simplest solution is to combine the antennas with a diplexer. Next option is to use a switching relay between the two.
Having two clients with two sdr’s on a single rotator will probably be a poor compromise.

I was thinking: can I switch the SDR with a pre-observation script? If I can, then my problem is solved. One station is scheduled for VHF/UHF reception and based on the frequency, I can select the proper SDR.

@SA2KNG: is rtl_tcp supported in the 1.9.2+sa2kng version?

I don’t know of such a switching routine. when using several on one host, they are usually separated by serial or similar. the flowgraph then always selects that serial.

I have not tested rtl_tcp, so I’m not sure.
