(If it wasn't CQ, then it was QST - do it cheap, go to your library and fumble around in the stacks ). Looking at the article in 73, I note that the circuit certainly does not cost to build anywhere near what the company producing the kits is charging.

If you think the added value is Stephen, the reason for the query was not to beat the author out of a kit fee (all $27). I was interested in finding out how the circuit worked (I'm pretty new to this stuff).

To: ham-homebrew@ucsd.edu Hello all! I am wondering if there is anyway I can add SSB to my Heathkit DX-60B (currently CW/AM) so I can do 10M SSB. I would prefer a "black box" between the transmitter and the antenna, although a hardware modification would be considered.

The ad says a 12 year old did the 2m kit. It would be real embarrassing if I ordered one and couldn't get it to work. Does anyone do 6m? In our area there is about 7 repeaters. Would it be safe to say, that you would not find anyone or hardly anyone on them? If I got one, how do you check when the radio is good for DX? If the conditions for DX are good do the repeaters still work?

Anybody seen a construction article for this >sort of thing (maybe when the 30-meter ham band was new?) QST a couple of years back had a design for a "secondary frequency standard" that consisted of the Neophyte receiver using a 10MHz crystal (with a variable capacitor to trim it onto WWV) and a divider chain to turn the 10MHz frequency into the usual comb frequency calibrator signal. Drop the divider and you have what you asked for (if you don't mind zero-beating an AM signal); or keep the divider and get two uses for the price of one :-).
