All items plus shipping and insurance from 89429:

1) HB 6-meter transverter/10-meter IF. Receive converter and low-level
transmit stages are the ARRL Handbook design. LO is on a DEMI VHFLO PC
board. PA stage is the DEMI 50PAK brick kit, which gives 19 watts output
for +25dbm drive at 28MHz. RX/low level TX/LO stages in one 7-1/2 x
7-1/2 inch cast aluminum box, DEMI PA in a second Hammond/LMB box and
the factory built DEMI PIN TR switch is in a third cast box. Requires
+12-13.5 volts DC and a contact closure to operate a small relay
(included) which keys the PIN TR switch and switches bias to the PA
stage. The system is not real pretty but it works very well! $175, which
is what the TR switch and PA stage alone are worth!

2) HP-415E SWR meter w/HP-420B crystal detector and AC cord. Detector
has been verified up to 15GHz on a radar system. Works beautifully with
'415E when driven by a 1kHz AM source...$95

3) Wavetek 3001-691 1-520MHz synthesized generator. -130 to +10dbm
output CW/AM/FM. Checked against laboratory calibrated test gear...works
fine. $125

4)  Waveguide components: WR-75: Absorptive load, 20db coupler and
90-degree E-plane bend (standard flange on one end and a flange about
double the normal height on the other...all like new). WR-112: 90-degree
H-plane bend (2) in good condition and manual waveguide switch which is
in rough shape and needs considerable cleaning. $20 for all items

5) LNB's: One Echo Star HEMT-1170 and two Sony FSL-1000's. All are
11.7-12.2GHz and are in unknown condition. $25 for all

6) Cellular band dual isolators. 0.5db insertion loss, >30db return loss
at 902MHz. Good to at least 50-watts (probably more) with pigtail N-male
connector in and chassis N-female connector out, Also has SMA sample
port at about -30db. $10, with documentation

7) HB 902 brick PA, 20-watts output for about 1/2-watt drive with an
MHW-820-3 PA module on a nice large heat sink. This was sold to a friend
as a linear amp but is actually class C. SMA connectors in and out. $40

8) New Toko 915MHz 3-pole helical resonators (spec'ed 15MHz BW). Toko
number 302HXPK-1286B (5HT style)...tiny things which I have retuned to
902MHz for a beacon transmitter. 25 available at $1.50 each

9) 2 new Cushcraft S8960B 896-960MHz unity gain base station antennas.
Nice beacon antennas...$20 each

10) PCS GaAsFET preamps...lots of neat surface mount components, but the
most important item is an Astrodyne DC to DC converter...nominal
12-volts in (9-18) and 9 volts at 870ma output. The input and output are
isolated from one another, so this can be used as a -9-volt bias source
(I'm using one that way and it works great).  Small...about 3x1-1/2x1/4
inches with PC mounting pins for input and output. 5 available at $10
with documentation (These are about $45 each from Astrodyne)

11) Directional coupler...-11.9db coupling 1.25db IL at 902/-10.2db
coupling 1.1db IL at 432/-10.9db coupling 0.85db IL at 222/
-13.5db coupling 0.6 IL at 144/-22db coupling 0.25db IL at 50MHz/-27db
coupling 0.25db IL at 28MHz...N-female connectors on all ports I've used
this directional coupler, with a good dummy load, to drive a transverter
directly with a 100 watt 10-meter transceiver (+50db and -27db coupling
give the +23db of drive required for that particular transverter). $20 

Thanks for the BW...I am finally able to get the funds together for a
single transceiver for both home and portable/rover operation. I will,
hopefully, be able to find a nice, clean, IC-706MkIIG in the next 3
weeks!
