Don and others, I just returned from buying a new DMM at RS and I didn't get very far in signal tracing the transmitter before I started getting some strange readings.
In my previous email, I mentioned that VPWR was reading high at 4.9V. This can sometimes point to a problem in the RF output detector so I checked all the components here and didn't find anything wrong so, following the instructions, continued on with the signal tracing. Transmit Mixer, Buffer, Band-Pass Filter, T-R Switch section - I am finding some odd voltages here. Voltages that do not match the expected results listed. These are all key-down voltages. Xmit Mixer Output: 0.181 (Expected: 0.016) Buffer Output: 2.05 (Expected: 0.200) Band-Pass Filter Output: 0.444 (Expected: 0.030) T-R Switch #1 Output: 0.439 (Expected: 0.029) I am doing the signal tracing using 40M. Do I need to worry about these?
