You may be able to make it work so that the TX will not directly desense
the RX. However the TX carrier

You can always extract the RX & put it in an RF tight box with EMI
feedthroughs. Then any freq. pair will be "OK". We did this to

Helps if I would include the actual frequencies instead of just xxx for
place markers!!!
Bottom of the repeater band through about 224.300-. The phenomenon is
centered on 224.000-

Duane and all,
If you plan on converting a Mastr II to 220, realize that there is a Segment
of frequencies that WILL NOT WORK full duplex in the same radio set. This is
a VERY similar situation to the UHF Mastr II's.
On a UHF Mastr II it is a well known and documented fact that there are
certain
Hi all
As a software and hardware engineer of 20 years and a ham also for over
20 years I would recommend an ICS controller.
And, if Kevin had the time to install the new Single M controller in a
Micor that he asked for you will see a Single M repeater controller
mounted internally in a Micor
As an engineer I recomend you go with a ready made 222MHz solution
such as those made by Kevin and Scott at Repeater-Builder.com. It is
a good choice if you do not have all the test equipment and skill to
make one of these run where they shouldn't.

You should one need one master II. But it will have to modify for full
duplex so do this as well as tuning it up completely on a vhf freq first
before starting the mods so that you know you are working with a good
unit.
I have been a bench tech for years and that mod it not for someone that
is n
