Since you are not seeing a doubling of the notch depth with the two
cavities in line, I suspect the cable length is incorrect as Eric
pointed out.
You also mention the tuning caps seems a little flaky. They
shouldn't. It may be that they have been lightning damaged, since
that is a known
Don't forget to figure the velocity factor of the cable you use.

You are likley to find that a 50 watt repeater transmitting on the same roof as
any other VHF radios (in the same command vehicle) will desense the other
radios.
I would recommend you consider something in the 20 watt or less range.
This is a case where less is better, especially since you
You will probably have to look for a used GR1225 repeater or perhaps a NOS
from a dealer as they were canceled by Motorola several months ago along with
the GR500 and RKR1225.

Hi RAY,
I would suggest the ICOM CY repeater as this is the same setup I installed in
the command trailer for Montgomery Co Search Rescue in TX.
It is similar to the Mot unit but is made up of 2 mobile units so if you have a
problem with 1, just that 1 could be swapped out.
This unit does have

Yes. The duplexer is a very narrow device, by necessity. It
likely will not allow varying more then 50-100 KHz from

Well...
First:
If you have the original cable set and know the frequency of

if you can obtain the spec'd notch value.
Second:
You might note the IFR 1600's generator output value and
crank it up min 10dB and better yet 20 dB.

Just bought an MSR2000. Got it working fine here at home, with a hb COR
circuit.
Took it to the site where there is a CAT500 controller. Hooked the CAT500
power to an A+ spot on the backplane. Power up and only the transmitter was
working. Receiver seemed completely dead. The A+ had

Regardless what controller you use with it. Not
sure if the TS-2000 would allow the same types of changes the other
Kenwood mobiles do.
The TS-2000 serial commands are similar to most other recent Kenwood
radios. If the controller supports other Kenwood HF radios, it will

Has anyone seen information on how to account for connector length when
wanting to build a cable of a specific length (i.e. half wavelength)?

Best offer, please reply off the list.
It depends on the connector.
N-male crimp connectors for RG214 and RG142/400 all add exactly 0.5 inches to
the length of the center conductor, so if you need a cable that has to be
exactly 12 inches from end-to-end using N-males (where the center pin does NOT

I talked to DB once about the DB 4060, and the cables are the same length for

So according to DB you do not need to change the cables.
