seeking?
What is the complete model number of the VHF PA you have to trade?

be to
side-mount the antenna on a standoff, with an insulated top brace. If the
antenna is constrained from waving in the wind, even a medium-duty antenna
will stand up well to blustery winter weather.

mount the diode right on the output terminal of the power supply. I use a
short piece of one inch wide, 1/4 inch thick copper bar to mount an
International Rectifier #122NQ030R Schottky diode, which itself has a 1/4-20
terminal screw. Very rugged and very reliable.

between the grounding prong of the AC
power plug and the negative output terminal. If the resistance is above
10,000 ohms, you're good to go. Otherwise, you've got to get under the
hood...

the same as the field-tunable range of a specific product. I was curious if
the window filter (AKA preselector) could be useful in the 70 cm Amateur
band without modifying the coupling loops or jumper cables.

Jeff,
Can you positively identify the window filters by part number? Also, what
is the useful frequency range of the units you purchased?

. Since you
can use a typical mobile notch duplexer for this application, it hardly
makes any sense to erect a tower so that you can run two antennas. Even so,
you should elevate your antenna as much as possible if you expect to get any
decent range.

Be careful about getting the proper replacement part. The basic M57729,
without a suffix letter, is for 430-450 MHz. The M57729L is for 400-420
MHz, and the M57729H is for 450-470 MHz. There are other versions, with
different suffixes, for other UHF bands.

Larry,
I know about MSR2000 and MSF5000 stations, but I've never heard of an
MSF2000. Most stations that are built for simplex (base) operation lack the
filtering that is standard in duplex (repeater) operation.
