I would add that I too got my start with the Russian RS satellites and would cast my preference for 15 and 10 meters as there is plenty of band width even if propagation on HF improves. I had good fun working the RS satellites with mnimal antennas and other equipment. I have no doubt that if we had a new bird on the HF bands it would be very active and get a lot of new comers hooked. Rick, W2JAZ
Got my vote for 15 up and 10 down. RS-12 was my second satellite (RS-10 was the first).
As noted, the entry to Ham radio is not via HF these days, but with no HEO sats, one can stretch the footprint pretty well with an HF bird, working it well below the horizon. That might attract more usage of the HF bands, and revitalize a lost mode of communication with some really bizarre propagation.

I would just miss the full duplex possibility mode "A" gives you.

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

You can do full duplex on HF if you have two HF rigs, only one needs receive capability so it is not that expensive.

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.

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.

Joe,
Some of the new dongles cover 10 meters, and the price is down below $100 for at least one, the Airspy.
While not technically a receiver, I have a radio shack HTX-100, still seen at larger hamfests for $40-75, which would work well. I used it as part of my AO-40 telemetry system. Don't recall I have ever used it for TX.
73s,
Alan WA4SCA

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,

Hi!
The inexpensive "RTL-SDR" dongles typically cover from around 24 to 1800 MHz, lack front-end filtering, and in my experiences are useless when there is a transmitter nearby - even a low power transmitter like an HT or FT-817. I have tried them, as well as the original FUNcube Dongle Pro (not the Pro+), and have been unable to work satellites with those as my receiver for full-duplex operation. There are some that work better, and have coverage throughout HF, VHF, UHF, and into the low microwave range...
FUNcube Dongle Pro+ - order from funcubedongle.com in the UK, cost including FedEx shipping to the USA is around US$ 200 depending on exchange rates.
SDRplay - available from sdrplay.com (based in the UK) or at HRO stores across the US for US$ 149.
These two have the front-end filtering that the RTL-SDR type of dongles lack, and have worked well for me as a downlink receiver for satellite work. I have been using an SDRplay for the past few months, and before that I had been using a FUNcube Dongle Pro+. The big advantage of the FUNcube Dongle Pro+ is that it is compatible with the FUNcube Dashboard program for AO-73 telemetry as well as the FoxTelem program for AO-85 telemetry. You can use other SDR receivers with these programs, but you will need to use some sort of virtual audio cable to connect the output from your SDR software to these dashboard programs. I prefer the SDRplay, but either of these units would work well for satellite and other receiving work. Both of these have worked well with the inexpensive Windows tablets I have been using for the past year or so, depending on the software you run on the tablet.
The Airspy R2 has frequency coverage similar to the "RTL-SDR" dongles, only covering 24-1800 MHz, and is sold in the USA by the airspy.us web site for US$ 199, or see airspy.com for sales to other countries. You would need to use an upconverter to get coverage throughout the HF range, and Airspy markets the Spyverter upconverter for US$ 59. There are other upconverters that could work with the Airspy.
Airspy is now selling an Airspy Mini, a smaller SDR receiver with the same 24-1800 MHz coverage as the original Airspy receiver, and airspy.us is selling these at US$ 114.95 initially. I have not tried either of the Airspy receivers, since I prefer to have an SDR receiver that doesn't require an upconverter for HF coverage.
73!

Funcube pro plus es better
RTLF-SDR Work Fine only 10 to 20db Gain more Not is Good Idea And add blocked filter for FM 88-108 nice

Wow
I remember going to AC4MY's shack and we used his FT-1000D for RS-12 in mode K. Had to connect the sub RX to a separate antenna....that was the rig I was in awe of then.
Many used 2 rigs for more K. There was a great approach in the Amsat journal to use a rotary encoder to tune 2 rigs with one knob. I almost finished mine to use with all the mono band all mode rigs. As you turned the encoder it would clock the up / down tuning buttons on the mic connector. The 910h acquisition preempted that project.
On RS10 RS12 and RS15 mode A, I used a TR-751 for 2m TX and a TS -450 for 10M RX from my truck and those terrestrial antennas provided contacts nicely. (Pre-dates the Arrow or elk)
I would stop in a parking lot and tilt the 2M antenna horizontal to radiate overhead.
That worked well !!!
Going forward:
If we had a preponderance of mode A or K the second / other rig could easily be a Radio Shack HTX10 / 100 Ir similar unless those running terrestrial microwave transverters got all of them :)
Thanks, Mike W4UOO

As noted, the entry to Ham radio is not via HF these days, but with no HEO sats, one can stretch the footprint pretty well with an HF bird, working it well below the horizon. That might attract more usage of the HF bands, and revitalize a lost mode of communication with some really bizarre propagation.

Ranger is still making 10/12m all mode radios, and you can find plenty of different ones at Truck Stops and places like www.copper.com. Work fine on 10m and don't need the "extra tune up" to cover that band.

Mine was a set of Drake B-line twins (R-4B, T-4XB) with the Drake 2-meter TC-2 transmit converter for Mode A (I also had the 2-meter downconverter and console). The twins worked great for Mode K on RS-12/13 half-duplex, as well. Homemade turnstile for the 2-meter uplink, fan dipole in the garage attic for HF. Pass predictions printed out with InstantTrack.
