Gary:

Thank you for the reply!

When I send CW with my TR-4C the "S" meter kicks up-scale as so does the 
current meter.  Is that normal?  

Also, since I'm a slow code sender (at this time) the relay pops-out a little 
too often as I pause between words.  I adjusted the anti-VOX as far as it will 
go, but there still doesn't seem to be enough "pause" for the relay not to 
kick-in.  It just seems to be annoying, and I'm hoping there's no hidden 
dangers of it doing this.  Any thoughts?

  Phil,
    Its not always easy to see the plate dip on the TR-4 plate meter, 
especially at low plate currents. Over time you will get an idea where the 
controls normally sit for a given band. I start out by setting the PLATE LOAD 
and TUNE controls in a ballpark position. Then I peak the receiver noise with 
the RF TUNE control. Then I put the transceiver in CW mode and adjust the XMTR 
GAIN control just enough to see an increase in plate current. Keeping the 
transceiver keyed only for brief periods I then adjust the RF TUNE and PLATE 
controls for maximum output. Next step is to bring the XMTR GAIN to 12:00 and 
adjust everything for maximum output. I tune all my Drakes this way. You really 
need to invest in a watt meter even if its just a relative output meter and not 
calibrated.
