Hey,
You can use the external card, just shield it as well as possible by placeing
it into a metal grounded case and using double or triple shieldee coaxial
condutors to link it to the radio. This wil prevent any interference from

If this is a 2m repeater, and the duplexer is mounted inside the VXR-7000
cabinet, it must be a mobile notch duplexer. I don't believe that such a
duplexer can perform with a 600 kHz split. Please elaborate on the make and
model of duplexer you have, and the RX and TX frequencies.

Bench testing showed the cavities performed as expected in
1/4 wave mode,
but no amount of loop tweaking or black magic cursing could
get the insertion
loss to acceptable levels when operated in 3/4 wave mode
(1296 MHz). Typical
IL was 2 to 3dB per can at these frequencies. All test
Okay, so you definitely have a mobile notch duplexer, which has practically
no bandpass effect since it works entirely by notching out the opposite
frequency in the split. Since the problem began when you changed the
antenna, my suspicion is that the new antenna's pattern allows more TX
signal to

Yes you will need to compensate for a little bit of GP loss, but this wont

Albert,
In the 30-50 MHz band, the antennas for a portable radio must be cut for
proper operation, over a very narrow range of frequencies. The length of a
whip antenna must be changed by 1/4-3/8 inch for every 1 MHz. Motorola
still offers the NAB6064B tunable antenna for the MT1000 radio,
Polyphaser.
Period.

Although Polyphaser protectors have a large and loyal following, they are
seldom used in high-end commercial two-way and cellular sites, where the
preference is for Huber+Suhner devices. H+S protectors are very expensive-
perhaps four or five times the cost of a Polyphaser- but they are machined
