After correcting some stupid mistakes (One bad solder joint and a unsoldered
connection) and the assistance of a few list members, I was able to get B+
to the oscillator.
The rig works except I have a very shallow plate current dip (at 120 mA (756
volts)) and I can not adjust the grid drive. It stays at 4 mA and can not be
changed with the drive control.
Also, the antenna loading control has NO effect on the plate current
reading.
The watt meter shows 100 watts into a dummy load.
The above conditions exist on any band, using several different xtals.
The rig was rebuilt with all new resistors and caps. . . .
Any ideas on correcting the above problem(s)?
TIA es 73
