EFJ stuff is pretty much all good. Some of it is easy to
work on and convert to amateur radio use. The sad part is
how EFJ was sold to a big corp and the operations moved
to Texas where they now only seem to sell and support P-25
radio stuff. In short they kind of left the conventional
land

I guess the rx microphonics problem isn't much of an issue as a repeater

More of a problem with noisy trucks...

Ok
Microphonics hasn't been a problem for the repeaters we've made
up. I would have never messed with two back to back Challengers
except someone gave me the repeater already made up and another
guy gave me a stack of radios. Then I'm guilty of buying more
of them off ebay because they were
Hi Bob,
The sad part is that no current low cost digital delay will easily
ramp back to zero time delay while in operation.
An analog delay could be ramped back to zero in operation to reduce
the delay after each new tx.
But alas no repeater mfgr is making cheap analog delays anymore...
Skip,
Interesting you bring up that idea.
I've had success with an initial CTCSS induced audio delay, ramped back to
zero, using the PT2399 controlled by a DS1803. I use it in the MP100
controllers on a multi hop link system. Talking from one end of the system to
the other result is no
