Hi gang, Well plans change. A few years back I was thinking I was going to
build up a killer 10 band rover station, but lately after I've started putting
the home station back on the air, I think I'm going with the bottom 6 bands
from home. Easier, less driving, less worrying about snowy roads, etc etc.. hi
hi. That makes these building blocks for 2304 and 3456 excess to my needs. I'll
entertain *reasonable offers* especially for more than one item. Pay by PayPal
OK and preferred actually. shipping extra. questions welcome. Here's what I
have:
DEMI 2304 low power transverter model 2304-144LP, SN205. This is an older xtal
controlled version with the MicroLO local oscillator. It's set up for split IF
at 144MHz and 1-10watt drive but that is easily changed. rig has the 28 v relay
driver in it to switch a Transco SMA relay. works great, hardly used. $180
2304MHz, 30 watt linear amp from Pyrojoe off eBay. here's the link:

this is the class A driver board out of a Spectrian 2300MHz rig. just
milliwatts input, runs on 12 volts, needs a heatsink. PyroJoe wants $145 for
these.. brand new I'll take $100
DEMI 3456 low power transverter model 3456-144LP, SN200. This is also the older
xtal controlled version with the MicroLO local oscillator. It's set up for
common IF at 144MHz and 1-10watt drive but that is easily changed. rig has the
28 v relay driver in it to switch a Transco SMA relay. works great, hardly
used. $180
3456MHz, ~30W Toshiba UM2683B power amp unmodified in original packaging. This
is the low power version which CAN be modified to be the high power (A) version
with a different voltage regulator and some other stuff, but at 25-30 watts
will cruise along the way it is just fine. There's a bunch of info online on
these amps and they are pretty much the standard for reasonable power on 3456
these days. Getting hard and harder to find it seems. I got this on eBay from
PyroJoe but he doesn't have any more. milliwatts input, runs on 12 volts. needs
heatsink. $150
I have a few heat sinks for above amps 9" x 7" x 1.5" (a few holes in these..
work fine on this amp) $20
also have a couple Transco "D" type sma relay used tested good: $25
ALSO........:
I have a pair of brand new Toshiba S-AV36 144MHz RF modules for sale. These are
the LDMOS ones that put out 80+ watts with 50 mW drive on 2 meters (134-174
MHz).. 12.5 v of course .. Pretty sure these are current in DEMI 2M
transverters. Also W6PQL has a board and other parts for an amp with these. I
bought them from China and waited about 2 weeks for them but paid $50 each
including shipping. I just want most of my $$ out of them so $50 each delivered
in the US. Merit at RF Parts wants $65 each plus ship.
thanks - bill, K1DY in Maine
