K3 Upgrade Path to Satellite Work.

[W7BRS Jeff Wandling]

Years ago, I used to own a IC-910h.

For some stupid reason I sold it when I got distracted by something else
that was important.  That was about 10 years ago.  Lesson learned.

I have always kept my K3 though.  I have done a bit of DX'ing with it for a
long while.

Now, I want to re-enter the Satellite work again, and I need a full duplex
Transceiver that can also work 2m/440.

Is there an upgrade path from a *SN #2100* era K3 to one that can do

a) Full Duplex (I assume this means getting the K3-SUB) and
b) Tx on 2m for uplink and Rx 440 on down,  or  Tx 2m on uplink and Rx 10m
down.

In other words, as long as I can do all of this:

1.  K3SUB can Rx 2m/440 and the main Tx 2m/440
2.  K3SUB can Rx HF and main Tx 2m/440


I don't expect to need to Tx 2m/440 more than 10W ever.

Then, we're good.

I'm lost on the elecraft page of parts/kits.  My how things have changed
there.

By the way I didn't see it, but is there a 1.2Ghz  KIT ?  Not required, but
would be nice.

Any kind soul, please help me out with an upgrade path of which kits I need
to get to do the full-duplex Satellite work that I used to enjoy.  (I'm all
set on the antennas and such, just need the upgrades to the RIG).

Thanks so much.

Sorry, but the K3 (or K3S) cannot do full duplex.
The only internal transverter is the K144XV.  Elecraft does have the XV
series external transverters for 50, 144, 222, and 432 MHz.

There is a built-in all mode Two Meter module for the K3 that you could install (K144XV).  

For 70CM, the only option for use with a K3 that I’m aware of are transverters.  Elecraft offers transverters for various bands (See:  http://www.elecraft.com/XV/XV.htm <http://www.elecraft.com/XV/XV.htm>) or look at product offerings from Down East Microwave.

Elecraft doesn’t offer a 1.2 GHz capability but Down East Microwave does.   However, until Fox-1C and Fox-1D are launched, there aren’t any L-Band uplink capable amateur satellites currently in service.  Fox-1C is manifested to fly on a SpaceX Falcon-9 SSO-A launch from Vandenberg AFB in early 2018   Fox-1D is currently expected to fly on a PSLV launch from the launch complex at Satish Dhawan Space Centre in Sriharikota, India in late 2017.

Hi Jeff. It would be a lot cheaper, better, and easier then with your K3 to do full duplex with two cheaper radios. Look at the SDR setups guys are now using on the sats. Get something like an Icom 7200, 7000, 706, or any other HF,2m,70cm multi band and mode radio and use the SDR for RX. This will get you full duplex for less than a good used 910. Checking the AMSAT.org archives would be a good place to start…
