[Johnson] Viking Ranger question - update

[Jim Brannigan]

Changing the fixed capacitors (non-NPO types) seems to have solved the problem.
I get a full bandspread now, will see how the final calibration goes......

A funny thing happened on the way to fixing the Ranger.....
To check capacitor leakage I put the capacitor in series with an HP variable supply and an HP-410C.
The capacitors I pulled from the Ranger showed a lot of leakage, a real lot....
Just for the heck of it I tested a new Mouser capacitor and it also showed a lot of leakage????
As I was pondering this, the variable supply went snap-crackle-pop and died......
There must have been an AC component in the output of the HP power supply and that showed up on the VTVM.....
(the VTVM was acting a little squirrelly)

The HP supply will go on the bench when the Ranger is cleared off......
Isn't electronics fun?  up one, then down one......never getting ahead......

73,

I finally got my Ranger up and running.
There are still a few minor quirkes and one major.

The VFO covers the two fundamental frequencies (1.75-2.0 and 7.0 to 7.4 
Mcs.) in about half the dial span.
no manner of tweaking will get the band spread to cover the full 180 degrees 
of the dial.

I feel that I am going to have to dismantle the radio (again) and change the 
VFO fixed capacitors.
