Thank you for your help Tadek sp8gpq My email [email protected] vy It should just pull off. Mine is friction fitted to the shaft. Its very tight. Be careful not to damage the knob.

Hello friends. Suddently, when it was transmiting, the transceiver lost power. Incuding D1 D5 D6. Also I check the Q50 2N Every thing was fine. By taking meassurements I realize that there is no voltage on the Q50 collector… The problem was the L51 inductor with a very hight resistence.

I replaced it an the problem was resolve. I hope that my experience can help in similar problems. Great write-up. It turns out C24 had failed shorted and taken out Q08 and the voltage regulator with it! When I was done repairing the radio, I decided to align the s-meter before closing everything up. The manual says to adjust VR01 and VR11 to adjust bottom-end and top-end of the s-meter. I was doing this and getting nowhere when I discovered by happenstance that VR10 and VR11 appear to be the actual two resistors that should be used to adjust the meter rather than VR01 and VR11 — I think that was a mistake in the manual.

Unfortunately, I had already adjusted VR01 and have no idea where it was set in the beginning. I looked up the part in the schematics and found that it is a variable resistor on the RF board and is in series with a thermistor TH01 and that, together, they set some kind of bias on Q18 which is in the RF receive IF? I dug through the service manual in hopes to find anything about adjusting this circuit, but was unsuccessful.
