Chirpy Viking Ranger

[Brian Carling]

Rod, I think you should check the actual voltage when keying it.
Look at the B+ coming to the VFO stages and see if it is dropping.

With the power off and all caps discharged, you should check the
value of the resistors with a meter. An open plate resistor or one
that has gone very high in value could produce this effect.

If all else fails, fly me in and I will fix it for you (grin!)
