Hi all,

Here's a complete 903 transverter/amplifier setup that i am   selling which 
belonged to Stan, K3IPM, you may have worked it during the past   couple 
January contests! All the gear has been used ONLY during january   contests for 
the past 4 years with the exception of the Tohtsu relay and   preamp which were 
new last year. The transverter is the modern type in   the clamshell box with 
Helical resonators and a PF0011 10 watt hybrid module   in the output, ATF101 
GaAs FET in the front end, adjustable drive level up to 10w or so. The amp runs 
on 12 volts (not 24 like some of the surplus stuff, so convenient for rover) 
and similar to the   old DEMI 2335PA which used a pair of discrete transistors 
combined with Sage   wireline. This one is setup for Gnd to TX instead of the 
normal +12 to TX.   (It's a 'straight thru' amp, no RF switching). Preamp is 
the old 33LNA in the   small 2" x 4" diecast (non-waterproof) box. All this 
stuff has been set up as   a unit and works well at well o
 ver 40 watts out. The amp is probably a bit drive   starved.. I am selling the 
components separately but will offer a discount if   you buy the whole package..
 
DEMI 903-144 10 watt 903 transverter   common IF, split RF. $280
DEMI 3350PA 10 watt in - 50 watt out linear power   amp using combined 2SC4624, 
12 volt (Steve says this was a production model for a short time). $160
DEMI 33LNA 903 preamp GaAs FET, <1dBNF >12db gain, type N   in and out $50
Tohtsu CX520D type N coax relay 12v, one year old, only used   for ONE contest 
$60
ALL of the above $500 and will throw in the   interconnecting cables and small 
keying circuit to make all above work   together with single PTT line, (PTT-L)
all in perfect working condition.   Shipping extra, PayPal payment  preferred.
 
can send pix if you want!
