Safe distance between RSPduos and a low-power WSPR transmitter?
Posted: Sat Nov 17, 2018 8:36 pm
I have two RSPduo's with several virtual receivers each running 24/7 to monitor a number of HF FT8 bands. One is connected to a Wellbrook ALA1530LNP magnetic loop antenna, the other to a W6LVP magnetic loop antenna.
Later today I'll be receiving one of these WSPR transmitters:

and plan to use it on the 40m, 30m, 20m and 17m bands. The documentation indicates that it puts out approximately 300 mW of power. I'm not sure yet what antenna I'll usually be using it with, but will test out various wire and vertical antennas.
My question: How far away do I need to keep the WSPR's antenna from the mag loops in order to prevent any possible damage to the RSPduo's? Is there a maximum signal strength I should be looking for in SDRUno if I tune to the WSPR frequency?
