I've decided to use the Yaesu FT-817ND has my transverter IF rig. The reasons
being low maximum RF output (5 watts) so less risk
to the transverters, good receiver, and small size. I'd welcome any comments
about the use of this rig has an IF rig. Pros or cons.
Like many rigs, the Yaesu uses one of those infernal DIN plugs on the rear. So
I'll be wiring up a cable. The 222 transverter is very straightforward with
simple phono plugs for PTT. However, the DEMI 2304 transverter is another
matter.
I'll try to describe it as best I can:
FRONT PANEL:
1 Power Switch
2 LED's. One marked "ON", the other "TX"
Legend: Down East Microwave, Inc.
Model 2304-144
S/N 212
Frenchtown, NJ
REAR PANEL (LEFT TO RIGHT)
Common IF Jack (BNC)
PTT (No jack at all. Rubber hole protector)
No Marking
(Jack, small SMA type? Not sure)
On the bottom of the board there are two RCA Phono Jacks:
One is labeled +VTX, and the other PTT
The PTT jack is connected to a small black relay. The relay has three
connections:
Left side=TXRF
Middle=Short Type "N" pigtail
Right=RXRF
(This is the T/R relay, right? Allowing the transverter to be connected to the
IF rig and use a single feedline)
Just below the T/R relay is another RCA Jack labeled "13.8vdc"
According to the owner, the transverter can handle up to 10 watts of drive.
My plan is to mount the transverter directly at the antenna (it only puts out 1
watt) and feed the 144mhz IF directly to it via hardline. Since the antenna is
in the attic, weatherproofing is not an issue)
So what connections do I need to make to the FT-817ND? And can I use the ACC
jack to control more than one transverter at a time? My plan would be to simply
turn off the 2.3ghz transverter when it isn't in use. I doubt that I'll make
more than 2-3 contacts regardless.
All help gratefully appreciated, as always.
