I have a Kenwood TS590 HF transceiver. When I am transmitting and speaking into the microphone, I can hear my audio slightly coming out of my speaker connected to the radio (SP-23), or headphones if used instead. The audio is intelligible and isn't distorted.
What is causing this? , and what would be a way to solve it? It didn't happen with my previous radio. I have tried different microphones so it's not a microphone issue.
It's hardly an RFI issue either. I have also an RF choke connected to the output of my radio and also at the input to my antenna. This is not affecting my transmitted audio on the receiving end. Thanks in advance.
