I just completed assembling a uBitx v5 and tried to put it on the air. It lit up and seemed to be receiving but when I keyed the mic there was a chattering noise and the TX/RX LED flashed on and off repeatedly then stayed showing in transmit status. I was connected to a resonant antenna through an SWR bridge and no power indicated going out. I turned the radio off then back on after disconnecting the mic but the TX light stayed lit.
I have been a ham for over 30 years but have been away from the hobby for the last 15+ hears. My current skill level is slightly above a new Technician and the only test equipment is a multimeter.
Any help in troubleshooting the problem would be appreciated.
73 and Merry Christmas
