Well, I don't know long this has been the issue on the feed. I noticed the multiplexer for my antennas took a dump. It's been introducing a hum into the radios, to which it's being transmitted into the feed. I pulled it out of the antenna line and made a direct connection to the receiver. I will try to improve my signal to my radio by duplexing another antenna to the radio as a band-aid ...1dB increase would make my happy.. Weekend project.
I have also added a noise filter into the audio cable between the radio / computer. This should have adjusted my audio unbalance between the two. I will work on tweeking the filter this weekend. Built a 50 dB PAD filter and I will replace the fixed value resistors with a var-resistor. If I can get rid of the hiss, I will do cart wheels. lol
Thanks to the KISM listeners for you patience.
