many thanks
no Iam genuinly interested in the way the systems work in other countries. I
agree that the system we have here in the UK works fine, a bit slow as you
have to apply for a rptr
addition to your licence, my rptr, as yet not on air, is GB3LP. Many thanks
for the explanation

Thanks Mark, we have received the schematic from Larry, WA4FOB. Note, I did
say that we WERE looking for the schematic. Guess I should have been
clearer.

Hello,
I know this is a bit off topic but I need a service manual for a IFR 1100 S,
is there any message groups out there that may be able to help? Looked all
over Yahoo and nada

Hi,
In doing the coordination form for non-ham repeater there were two lines

i do the ULS-on-line form and then print it and mail it to the

errors while only allowing input into required fields.

Hi all,
I am about to set up a V/UHF repeater. got all the bits all I need is
some info about tuning up the TKR-750 850 I believe that you need to
tune up the set onto the required frequency once programmed up but I
can not find any info in the handbooks. Any help will be welcome.

You can't beat a really good squelch circuit. Much
as I always seek real alternatives, the dual function
Motorola squelch circuits seem to be some of the best
designs (there is more than one dual function Motorola
squelch circuit). Fast detecting - mute/gate time is
the desired animal.

MY general definition is still a valid one. it doesn't matter if it is
a Micor or MASTRII. the difference is how the detector works, meaning
the attack and delay timming is adjusted depending on the level of
quieting seen at the detector.
