Hi guys, been scanning for over 20 years but new to the broadcasting end of it so please bear with me.
I'm getting a pretty bad hum during transmissions on my feed. I've searched the forums and tried / ruled out pretty much everything I can think of.
First thing I thought was the wall wort, I would have purchased a ground loop isolator but I unplugged it and ran of batteries and the hum is still there.
I have tried two different scanners, both with same results. I'm using all mono cables, actually the exact ones described here.
All plugs and cables are pushed all the way in / clean.
I did some testing and when I put on a weather channel the hum is gone, but when I go back to the primary channel, the hum is back.
I want to have a headphone splitter so I can set up a speaker to run off the same scanner that is providing my feed. I get no hum out of that speaker. I disconnected the splitter and tried running the cable directly from scanner to PC and the hum is still there regardless if I have the splitter in place or not.
I am using the line input (not mic) of the PC. I tried playing with the volume settings on there IE: scanner volume high, line in volume low and vice versa. The only thing I could not find a setting for was the gain on the PC line in??
I've heard much worse feeds than mine, but I've also heard much much much better. I would really like to improve the sound quality, so any help would be great.
Should I try an external (USB) sound card?
Here is a link to my feed in case you want to hear it for yourself.
