There was a strange arcing on the filter can from day one. Thought it was poor
solder connections, wrong. I replace the caps with
The crystals arrived today and the DX-60 tunes up nicely
and on frequency. But the modulation is horribly distorted. I put in a
new 12AX7 preamp and checked voltages. All OK. I bypassed the preamp
stage and subbed in a known good amp. Still bad. I'll keep working on
it.

I would like to thank everyone for the quick, friendly, and informative
responses. I am confident I will be good to go as soon as the crystals arrive,
perhaps tomorrow.
This was another fine example of the Ham Radio spirit.I hope to see you on AM
very soon!

I have Purchased a gem of a Heathkit DX-60 AM Transmitter.I was wondering if
someone had a better idea that what I have for T/R switching. I need to use the

I agree. There are many orphaned links, and it is not the easiest site to
navigate through. I understand it is new and the are working on it. They should
have done more testing before releasing the new site.
Anyway. try this link. I hope it helps.
Speaking of AM Transmitters, does anyone have a source for plans to build an AM
Transmitter for 75 meters in the 15-25 watt range?Thanks.

No kidding! Do we honestly think ALL licensed HAMs adhere to the legal limit

who go well over the legal limit. And don't look at my 5kW unit either!Kidding!
