The R212...lol. To tell you the truth...my head is swimming but I'm going to beat this thing. Ok...first we had the frequency reversal on the schematics going into the mixer IC5. Now. looking at the silk screening on the board. I have diodes where resistors were, capacitors where diodes were and we have this R212 thing. All three pics are of made in Malaysia boards. The top pic is of the radio I am working on. The two below are from the parts bin but have a clearer view of the components. Take a look in the area between the 7.8000MHz filter output to the mixer. looks like they had to jumper the 2 frequencies to the other inputs of IC5. Anyways, I replaced the 7.8000Mhz crystal filter. I had nothing coming out it in the test radio. I have installed a used crystal filter in this 148 GTL and I now have 7.8000MHz coming out of the filter. Tracing back from IC3 Pin7 to the output of the crystal filter I have the 7.8000MHz. But now it takes a different route than what is in the schematic so I am making my own by tracing the signal from the crystal filter down to the mixer input. The +8V TX is coming off R212 before it even hits R191.
