Did Collins specify what input impedance a meter should be to properly read the resistance values in the manuals? I did see where a TS-352 was mentioned but that's selectable between 20,000 ohms/volt and 1,000 ohms/volt.
I started checking the RF Deck in my R-390 and, starting with V201, I noted a few values that are significantly high. I was using a modern DMM with 10M input impedance so not sure if that could be the problem but I doubt it would account for that much difference but who knows. The voltages were off a bit as well but not nearly as much as the resistance values. I suspect the radio will still work with wacky voltages but the R values really have me thinking I have work to do.
