Indeed, these are great little
transverters, and they are quite easy to set up and use. Drive
'em with between 1/4 W and 5 W (adjustable in the transverter) at
144 MHz, and it delivers 2 to 2.5 W at 1296 MHz.
Right out of the box I was able to connect one to an old Yaesu
FT-290R and complete QSOs off the Olympics with Jim (K7ND) and
Mike (KD7TS). I used one during the recent ARRL UHF contest
with the FT-290R and an 18 W amplifier and either a 10 el WA6VJB
"cheap yagi" or a 22 el loop yagi, and made 35 QSOs, including 4
QSOs from CN85 back into CN87 (write-up here:
http://tinyurl.com/WW7DUHF2014).
The transverter can be configured for 3 types of T/R control:
-- RF sensing of the IF rig
-- PTT to ground
-- +12V on the IF coax (particularly useful with an FT-290R as
Mike pointed out to me)
Most options are jumper-selectable. It comes configured with
built in T/R switching w/ single connection to the antenna, but
can be reconfigured (via moving a surface mount component) for
separate transmit and receive connections for use with amps and/or
preamps and a single external T/R relay. There is a built in 25
ms "delay on transmit" output that can be utilized as a simple
sequencer. And it does offsets for repeaters.
It uses multi-color LEDs to indicate proper IF drive level and
SWR. There are also output voltages proportional to forward and
reverse power that can be used for external metering.
All this for $200 is a real bargain. Down East Microwave
discontinued their 1296 MHz transverter line a few years ago (for
"redesign"), and they were twice the price, so I believe this is
the only game in town for low cost 1296 MHz transverters. I
mean, that's cheaper than any 1296 MHz FM rig on the market.
The seller seems to be putting a couple on Ebay every two weeks or
so, and they sell pretty quickly. You can contact the seller
directly to purchase one outside of Ebay. See the SG-Lab web site
for more information about the transverter and contact
information:

I received mine in something like a week (and it came with a 2
element PC board yagi).
If you have any interest at all in 1296 MHz, I recommend you pick
up one of these puppies.
Best,
