When i key up, my external meter shows nothing going out, cannot even check swr as the meter doesnt budge, zero watts out it appears. i can get in my truck and drive around the block and talk to my kid on it and 1 block away it hits my mobile with 3 to5 s units and the audio is in the toilet. so it is getting out but its barely, 2 blocks away it cant be heard and its connected to my base antenna.

I swapped the pre-driver, driver, final from a working 148 with matching parts but didnt help, then I tested the voltage regulator and PLL (i think i have correct testing info but not positive), all good on those, no change.

what else could it be?
