Dear Joe,
Yes, we have observed the signal with a spectrum analyser. It is a broadband
noise covering our entire TETRA band.
Yes, the transmitter is keyed up continually.
Regarding oscillation, what circuitry will develop the oscillation in 3 days?
We are thinking about the heat problem too,
Hello Kent,
Have you looked at the noise on a spectrum analyzer? Is is broadbanded
noise, or is it just on your receiver frequencies? If it is only on
specific frequencies, is it frequency stable or does it drift around?
Also, do any of your transmitters stay constantly keyed up?

IMHO Amphenol Connectors are hard to beat and I personally do not know of
any better. Especially when it comes to adapters they will outlast the
cheapies many times over. Even when they discolor because of years of

ham use,
Why not just buy a retired GE MASTR-II station and convert it?

They could probably make a Band A3 39-50 MHz MX-800 play on 6m ham.
But I am led to believe that the Connex line may not be a purebred. There is
certainly a remarkable price difference between those labeled Amphenol
Connex and one labeled Amphenol.

Chris,
Having work on many in the past and rebuilt 3 amp after lightning strikes.
Needless to say it took several hours to repair each and 3 days to rebuild
each.
I do not know if the parts are still available from Motorola, but they may
be. I know they do not repair them at the depot anymore.

I have a DeskTrac AXL43SUM7000BT 146-174. Can I successfully push the

goes up to 80w, clearly not good.

The Connex line is the cheapie line. It's still better than the real cheap
imported crap, but as the price indicates, nowhere near the quality of the main
mil-spec products. That said, I use quite a bit of the Connex stuff unless it's
a critical application. You do get what you pay for.

If you put a cable which is 1/4-wavelength at VHF between the T and the UHF

Hello again.
So after messing with the exciter. (last post on this topic the exciter only
put out .1 mw)
The exciter will put out, 300mw to the input of FL101. This is just a simple
tune up. But FL101 blocks the RF 'since it seems to be out of range'.
Can the filter be re-build, changed,
Jason,
You definitely should not bypass FL101, because it performs an important
function. Although the service manual does not provide any information
about tuning FL101, the schematic diagram reveals that it contains four
helical resonators that do appear to have tuning slugs which act as
38 matches
