Hello Bill,
What does the manufacturer say ?
Maybe it is a defective unit. Replace.
Does it have a built in microphone ? Use the internal mic.
hardwire the transceiver RX channel to the audio input, with a suitable shielded cable.

I am using an Olympus digital audio recorder for logging LEO passes, because I can directly transfer a .wma to my PC from it (versus the tape recorder I used in the 90's).
I am using an extension clip-on mic. I am finding that it generates a lot of RF crud on 435, enough to swamp the RX if I am not careful.
Beside a torroid on the mic cable, and maybe a foil/mesh cover over the recorder (maybe one of those new-fangled RF-ID protecting wallets), anything else I should try?
