Well, guys, I had time last night to look at it again. To answer a
couple of questions - The plate supply is 150V regulated. The plate
voltage is about 70 volts because I have a 100K resistor between B+
and the parallel tank (with a .01 bypass at the junction to ground).

What I did last nite was to use a different coil which reduced the C/L
ratio. previously the tank cap was 2000pf. now it is about 200. This
resulted in a plate signal of 10 to 15V p-p, an increase of at least
3 times. Guess I will be satisfied with this.

I did do as many of you suggested and changed the bias, even all the way
to cutoff. All that did was reduce the output. I replaced the 100K plate
dropping resistor with a 2.5mH RF choke and the output also dropped slightly
so I went back to the 100K resistor. The cathode has 3.3K to ground.
Grid leak is 1Meg.

There is no way I can increase either of the input signals. Since the
output has increased quite a bit by using a more "normal" L/C ratio,
I'll leave it at that.

Anchorites and Glowbuggers,

I need a manual for the Heath HX-30 6M SSB Transmitter.  Will pay costs.

Also need one small chrome knob for same.


?  Was there a companion receiver?  Any one got one for sale?

Thanks.

Can anyone please tell me in what years the first five editions of the 
ARRL Handbook were published?

Thanks.

Per a couple of suggestions I am sending the code word twice in place of 
so many VVV's.

Format:   vvv 250 mw <code word>  <code word> de ak0b/b qrp beacon

This 250 milliwatt should give your receivers and antennas a good test.  
Code speed is 12 wpm.  Freq is 7033 khz.

Cheers de stan ak0b
