Most should know this but do not try to measure voltages on the power out amp transistors and key the transmitter at the same time. I did this once on an MFJ 40M SSB QRP rig, across a choke, and the meter became a pretty memory. RF voltages are much higher than one may imagine.

Here are the measurements that I have.? INPUT: 7.87 OUTPUT: 12.85 That may be backward as to what you were wanting, I determined the pins from the datasheet that I found here:? I could not test the IRF510 PA MOSFETs because it was this time that gravity decided to ruthlessly attack my multimeter and hurled it to the floor and breaking it. I hope to have a new meter by the end of the day and I will test the IR510 PA MOSFETs then.? -- '72
