What band, what power level and what mode?
I just finished 25 watts CW on 475
KHZ.....Also, an inexpensive 3450 MHZ
AM design.....Progress is being made on a 22
dollar voice transceiver on
I have done
a lot of circuit boards also.....The attached photo
shows a 3 board set that can be adapted for roughly
200 KHZ to 15 MHZ CW.....
board on the left is the CW oscillator-driver
board.....All harmonics are at least 60 dBs down.....
board in the middle is the FET power
amplifier.....Tuned and also has impedance matching to
get a 50 Ohm output.....With harmonics.....
The board on
the right is a low pass filter that runs cool and
harmonics are down at least 60
dBs.....Runs cool at 25 watts.....
All this on
a 4" by 6" piece of circuit board.....
As you can
gather, I use all bands and modes of operation.....
If I can help.....Gary...K5QNM...EM36

have been building kits from other
countries and decided it was about time to
bring my enjoyment to a new level. Instead
of building kits I would like to try my
hand at designing and building my own
do have a basic understanding in
electronics and mathematics, however I
have not had much experience in the
experimental side of our hobby.
Does anyone has any favorite
resources they would share?
