Radio Make and Model: Uniden pc 68xl
PCB Number:
PLL Number:
Test gear available: Bird 43p, O'scope, mutlimeters, freq. counter, signal generator....
Symptoms: Lost transmit.... Keyup
What is working: Tx/Rx light changes color, receive works....
What has been tried: Changed Q9, Q19, final, driver, D12, IC2 and IC3....
Did it suddenly happen ?: yes
Anything else that may be of help?:
If I lift one end of D12 the transmit comes back but at only around half power.... I replaced D12 and it made not difference.... Checked R60, R70, R47, R46, R108.... Everything seems to check out but I still have no keyup with D12 soldered in place.... Radio keys with one leg lifted on D12 and only half power as previously stated.... This thing is driving me nuts and I know I'm overlooking somethng simple because I'm frustrated.... Any Ideas????
