Actually, I seem to recall seeing an article about the same DF unit in an
issue of (I think it was) CQ in the last year or so - no PCB layout, just the
schematic and parts list. (If it wasn't CQ, then it was QST - do it cheap, go
to your library and fumble around in the stacks <g> ). 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.

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).

Subject: Heathkit DX-60B Mod?
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. If you have any ideas,
please e-mail me at ncc2001@cwis.unomaha.edu or packet at
N0YBC@WB0BLR.#SWIA.IA.USA.NOAM. Thanks.

Converting a DX-60 to SSB would be like converting an AM radio into a TV set.
Not worth it. Easier to start over from scratch.

To: ham-homebrew@ucsd.edu
Did anyone see the Ramsey 6m kit? 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?

To: ham-homebrew@ucsd.edu
I have need for a cheap, simple, easy to build WWV receiver. All I need
is their audio; and I figure the single frequency of 10MHz will be reliable
enough for my purposes. 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 :-).
