Thanks Johnny! A lot of thunder crashes on 80 tonight and copy was pretty rough. I was running my TAC-1 40 & 80 Meter radios tonight. Used them last week too but when you did not respond back to me on

Thanks to Dave, NM0S, who pointed me in the right direction on the RX muting circuit. So D1 is correct on the 80A schematic. After fixing that I still had RX muted so I swapped out the 180 pf cap and

Hi Jim, I'll have my MTR5B with me at Ozarkcon. I got it in February and really have not had a chance to use it much yet. Feel free to look me up and watch me figure out how to use it :-) It does not
