Subject: 2 MBPS 10 GHz Link Boards Available
To: glenne@srlr12.sr.hp.com, bdale@col.hp.com, ron@chaos.eng.wayne.edu,
Receiver boards are now (at last!) available for the n6gn desinged,
2 MBPS, 10 GHz microwave link as described in the ARRL Handbook and
other places. You'll still need to make the 1st IF board yourself,
but trust me, that's easy. I didn't believe Glenn at first, just
follow the procedure in the article and it works!
The receiver board is 4-3/4 x 5-3/4", double sided, and drilled, *but
not plated through* (hence you'll have to solder top and bottom leads
in some cases). This shouldn't be a big problem because there are no
signal traces on the component side--it's all ground plane.
Folks who helped make these boards available (though they may not all
want to admit it :-) are Glenn Elmore n6gn (of course), John Conner
wd0fhg, Ron Atkinson n8fow, Fred Reimers kf9gx, Bdale Garbee n3eua,
and Jon Bloom ke3z.
They're available from:
Fred A. Reimers kf9gx
FAR Circuits
18N640 Field Ct.
Dundee, IL 60118-9269
for $15. Fred just shipped 8 to me for $5 postage, but I'm not sure
what the rate would be for smaller quantities.

I'm not sure of the phone number for A & A Engineering, but they often
advertise in QST and 73. They sell a line of low cost gadgets for
amateur use such as low-cost spectrum analyzer front ends for your
scope etc. I have their catalog at home, but I am working in Toronto
for the summer and it will be a few days before I can get the information.
I do have two of the filters here, and the markings on them are:
TEMEX TE5120
Probably not of much use but you never know.
The Maxar/Moxy radios look interesting for high speed, they are a single
conversion receiver with no second IF. I installed wider filters in a
radio last weekend to make a pair and have been burning them in on the
bench since then. I don't think the second radio was quite as flat in the
passband but I was using a different sweeper than what I used for the first
so that is not too conclusive. So far though the results have been
encouraging.
