Old school Nitelogger

[Hillside1]

I've started to upgrade my "radio shack" by getting rid of the tape recorders (don't laugh) and record to computer using Proscan. I started with several BCD996T's and fed the audio out to a Nitelogger and the Nitelogger audio out to the computer, all using mono cable. It worked on all those radios and a 996XT. I wanted to do the same to several SDS200's but as soon as I connect to the computer it mutes the audio. I read something elsewhere that the SDS200 is a stereo vs. mono signal. could this be the cause?? If so, what would the workaround be in this case? I hate to give up the Niteloggers as they've never malfunctioned in over 20 years of heavy usage 24/7.

Also, weirdly, 1 BCD536HP works and another doesn't.

Could be a ground loop🤔
Might try adding a ground loop isolator

Maybe try some stereo to mono adapters? Just for which direction you need it to go.

Amazon.com : Stereo To Mono Adapter

Just for clarification, does the audio mute on the SDS200, or on the PC?

I connect the radio to the nitelogger with a mono cable. Then I connect the output of the nitelogger to the computer also with a mono cable. When I connect to the computer the audio mutes on the nitelogger. Only with SDS radios. Configuration works fine with the earlier products. I'll give your adapter suggestion a try. Should have 1 or 2 laying around here somewhere.
