    alright I Removed the glue “concrete lol” and I officially have transmit and receive again. I’m not surprised but the receive is poor and I’m not sure on how well it transmits. But it does both now so that’s a plus! I had to take my antenna down for maintenance. I’m currently testing the...

    The other cobra is a hand held. I got more mics hanging around. Currently I have a dead key but, 0 swing and 0 modulation. Probably a good idea doing this after some sleep. I’ll probably make a little more sense if I’m not as tired. Thanks for giving me a hand. I’ll turn the knobs and they...

    On top of that it isn’t consistent either. My voice isn’t heard. I have a little cobra 36 st I use to hear myself with when I’m checking my audio
