[Lowfer] Popular Electronics Article(s)

[Ed Phillips]

"Some one on this list wanted to know about an article in Pop Tronics
circa 
1972.  It was a Popular Electronics 1 watt tube transmitter for the 1750 
meter meter band.  Tell you what.  I will scan the article for you and
send 
it to you if you can tell me where I can purchase a complete 1750 meter 
transmitter or kit.  I checked with Palomar Engineering.  They still
make 
the down converter but no transmitter.  Remember LF Engineering CO out
of 
East Haven Conneticut?  Well, they are kaput also.  I have a precision 
crystal for 178.0003 that worked in the Palomar Engineering 
transmitter. 
Anyway, I'de like to get back into the frey again so I need a
transmitter.

	That Palomar transmitter used most of the circuit I designed for my
first solid-state beacon back in 1976; Althouse got it from me.  The
difference was that he built it on a circuit card whereas mine was built
in a box with lots of decoupling and used ferrite beads for VHF spur
rejection.  Result was that the Palomar transmitter turned into a huge
TVI generator!  Still irks me.  I can supply a copy of the circuit (very
simple) if anyone wants it.  In mine I used a crystal 32 x the output
frequency and divided down but I can't remember if he did or not.  I
gave the prototype to someone but can't remember who right now.
