Hi,
Does anyone have a solution for the infamous newer 148gtl "D" made in China? I have the usual highly distorted transmit audio on SSB. The radio will run about 1-5 watts PEP and sound clean, but any more will sound horrible. Tried running the clarifier from an external regulated power supply at 7.5 volts and didn't help. Also changed C172 to 2200uF and that didn't help. The little 7809 regulator gets its 13.8 volts directly from the power switch, no hash filters inline here. Not sure it was a voltage sag problem but tried those things to eliminate them. Any help will be greatly appreciated. Tnx.
