<DIV>Hi All,</DIV>
<DIV>I think a great interface for a preselector would be the DB25 on
Ozy. We could output 16 bits of 4 bit BCD to give 10 KHz resolution to
tune a preselector, This would be the center frequency on the
display. Phil, You may remember the schematic I sent you of the
Cubic pre-post selector. There are a number of different mil versions by
Collins and Harris to name two others. The Cubic is set up to handle 1/2
watt of power and has a TR relay. </DIV>
<DIV>This would also be a good interface for anyone who would want to
build a homebrew preselector. I was on the air a few nights ago and
something in the area saturated the Mercury A/D for the first time
so I see a need for a better preselector rather than a simple
wideband filter. The Harris RF590 has a nice small tunable unit
but I don't know the interface. A serial string would also
work but I think 10 KHz resolution should be enough.</DIV>
<DIV>I have used my Cubic pre-post selector in series with Mercury and
find the performance quite good. I would think this is the next
step in improving a beautiful receiver. </DIV>

<DIV>P.S. My friends have been sending my on air tapes of Penny with the
comment that I have never sounded better. </DIV>
