Geee-----we're on a roll! Thanks for good info on my previous query. Now,
a new one:

Just put a small MFJ -949E tuner into my antenna system.

Thing works great. The only weird thing is I notice the tuning is extremely
"tight" and "goosey". The slightest movement of the variable caps produces
jumps in meter readings. Having said that, I can still manage with it.

Years ago, this kind of tuning effect was from hand capacity, when just
about everything in the shack was RF hot.

However, this isn't what we're dealing with here. Once my controls are set,
touching around the tuner anywhere doesn't alter anything. So, it's not
hand capacity/coupling.

What is this effect indicative of? Just curious.
