[Boatanchors] how to read microvolts

[Dick KF4NS]

Many thanks, pretty much what I was beginning to think was the case 
anyway.  Will look for a better generator from amongst those mentioned 
here in the list. Anybody want to buy a great looking Heathkit LG-1 
which by the way, functions as intended? I completely recapped it and 
adjusted all resistors within tolerance except for the attenuator 
resistors which are on order, has 3-wire cord now and new tubes.

Thanks and 73, Dick KF4NS
