I'm having a technical problem and was wondering if anyone had any suggestions. I've been experimenting with using an FT-991A transmitter and SDR receiver to run full-duplex on the satellites. My problem is as soon as I key the FT-991A transmitter, my SDR receiver waterfall goes completely white and I don't hear anything but static. Classic overload symptoms.
Plastic case of the RSP1A == no shielding. The front-end filters can't stop that which goes right around them.
If you put the RSP1A into a metal box and install a USB EMI filter, I'd wager the problem will go away.
