Ron,
My suggestion wasn't really to tee both radios together, but to minimize
interference between them if you used separate antennas that were
relatively close to each other.
To combine two systems into one antenna poses some significant
challenges. Were this a commercial installation with the

WACOMs for around $400 and 6-cavity ones for no more than $500-550. There
were some at Dayton for $300-$400, as well. Check with your local U.S.

I have one similar in Rockdale, TX with a Fire Repeater, plus a 155.280 EMS

My view is that a crossband repeater is not a simplex repeater. If you
are going to operate in the Amateur Radio bands, you can use a dual-band
transceiver with the cross-band repeat function, such as Alinco's
DR-605T. In the commercial bands, you can use Link Communications'

I bought an Icom IC-2720 for the sake of its crossband repeater
capability, and would like to use it in that role with my 440 MHz HT as

the 2720 does not. Additionally, there is the matter of IDing o

Several people responded to my need for an amp, and thought we had
one donated, however turns out it was no count, good intentions on
the gentleman's part. As funds are low for the reapeater project, I
would like to entertain a trade on a full duty cycle 2 meter
repeater amp, 5 watts or less d
Neil,
One very serious issue with what you are considering is that of the
severe limiting that takes place in an FM receiver's IF stages. The purpose
of this limiting is to remove the AM component of the incoming signal. Even
if you feed an AM detector in parallel with the discriminator you won
I think I got rid of all of my Sensicon 'A's a very long time ago.
Perhaps Mike Morris still has some in his garage museum. If you
don't believe me, you really need to go look or have Mike take
pictures of it.
Now that you mention it, I do remember someone seriously padding
those
Tom,
Like I said in the earlier email there was some reason I moved one to
somewhere that frequency, pretty sure it was some kind of NASA link from
orbiting aircraft and it was FM, not AM.

Neil,
I once moved a Motorola Sensicon "A" receiver from 173 to 121 MHz for some
reason I can't remember why in the world I modified to that frequency. it's
been so long ago but it worked fine. It took a little work and I changed
the number of times the oscillator multiplier multiplied to get the
You're welcome! Since the YLN4017A board is still an active part number
with Motorola, perhaps you can get the information you seek by calling
Parts ID at 800-422-4210 and asking for the manual number that covers
YLN4017A. The clerk will advise you of the complete manuals that
include the informa
Thank you Eric, this is also the first
time i see this board even i have seen 100's
of Mitreks, i can't find also any info on
the manuals i have, will try to draw a
schematic from it and try to figure what
it does

The YLN4017A is listed as "BD BUSCOM AUDIO INTFC" and is priced at
$115.33, but I have never seen one in use.
