I worked a lot of Mode K back in the day with 2 XCVRsand dipoles and put
many countries in the Log. Half-Dplxwas very easy with 1 XCVR and a

There's no technical reason you can't do full duplex with Mode K.

There are numerous shortwave receivers with a BFO that would likely suffice.
I know many RS-12/13 QSOs were made using cheap shortwave receivers to
receive the downlink.

Thanks Paul,
Great report and awesome work at Dayton. We, the folks inside at the booth,
benefited greatly. We had new members because of the demo and many
beginners books and antennas were obtained at the booth.
Thanks again to all the demo volunteers for supporting AMSAT!

Yes, exactly.
My first satellite was RS-10. 2m all-mode, 10 watts to a copper pipe
J-pole for the uplink, and a Radio Shack DX-440 shortwave receiver
connected to a piece of wire strung to a tree in the back yard for the
downlink. Pretty sure I did the same for RS-12.
Worked Arizona from California for my first contact. Second contact was
to New York. That was all it took; I was hooked.

Paul,
Thanks for posting that report on the AMSAT demonstration station
activities last weekend. I was not able to travel to Dayton
this year, but was happy to work the different voices on the microphone
over a few passes on Saturday and Sunday (KM4IPF, K8YSE, KO4MA, and
N8HM) via 4 different satellites (AO-73, AO-85, FO-29, SO-50). I
had also stopped and listened to part of an AO-85 pass on Friday
morning on my way to the office, with K8YSE on the mic. I posted that
on YouTube:
https://www.youtube.com/watch?v=LmFlxxLvOys
I used my Wouxun KG-UV9D with a Nagoya NA-701 dual-band duckie to
hear that pass. If I had brought my Elk log periodic, I could have
just as easily worked John that morning as well.
Working the demonstration station isn't the same as being there, but
it is still fun to be on the other end of the QSOs with that station.
For me, I had two chances to work the AMSAT station on very low
passes (SO-50 on Saturday morning, AO-73 on Sunday morning), and
the Saturday SO-50 pass was my first time working Hope KM4IPF. I
enjoyed watching the video of that pass, and hearing my QSO with
her from that end of the QSO.
73!

first satellite station was a Swan 350 and a R3A receiver, commodore 64

What kind of price are you looking for each of these? It?s nice to know
where to start with an offer.

some of my radios may have to go. All are in clean, working condition unless
otherwise specified. All are currently connected to an antenna and can be
demoed or we can set up a QSO. I've talked with a few of you using these
rigs already. :) These are older radios (mid-'80s), but are well-known for
being very good rigs.

suggest replacing it as a matter of course, though, whenever you get around
to it.

First, it seems to put out half power (about 35W); maybe one of the two
final transistors is blown. Two, I think it has a loose wire going to the
internal speaker; headphones work perfectly (looking at the schematic, I can
see which connection may be loose, but I've not tried to fix it yet). I've
upgraded this unit with a new RAM board (cost: $60).

I've used my 440 horizontal loop for low-power testing. I was able to have a
QSO on a local repeater with no problems. I do not have an SWR/power meter
for this band, either, so I can't verify output. It seems to work fine based
on the little use I've given it.

A mode K satellite would be cool, but not many rigs can do full duplex on
Mode K. The FT847, TS2000 and Icom 9100 can't. It would almost take 2 HF
rigs, or a Yaesu FTDX9000,

I bought a MOT spectra 20w 900-MHz FM rig for about $50 on
e-bay. The seller programmed it for my desired ham frequencies
(about 8 channels) for free. Mainly use 927.5 MHz simplex.
If you want to operate CW/SSB on 902 or 903 MHz call DEMI with credit
card in hand.
What is hard is to find very many station on these bands.
I have my 900 station driving a MOT amp outputting 60w to 18-element
loop-yagi (google Directive Systems).
So the hardest part of mw is convincing anyone to move up here.
I am QRV from 500-KHz to 10-GHz.
hint - using a solder iron helps

Getting above 1 GHz isn't easy. Actually, 900 isn't that easy,
either. In fact, I'm looking for a clean IC910H with the L-band
module so I can do just as you suggest. :-)
