Hi Gang,
If I remember correctly. My PM3 always had a little offset caused by
the loading of the transmitter and / or external resistance in the power
supply or lantern battery I used. I made a lot of contacts with that
little rig and only had a problem with offset on rare occasions.
My advice, if you want offset, buy a rig with it already installed.
PM3s are getting rare. It would be a shame to modify one.
