Good Day,
We are using simplex radio (using single frequency for transmit and receive)
and we would like to build a repeater. We would appreciate it if anybody could
advise us how to do it.
Best Regards,

It doesn't hurt to take a hard look at yourself
from time to time, and
this should help get you started.
During a visit to a mental asylum, a visitor
asked the Director what the
criterion was that defined whether or not a

Hi Steve,
The 'FH duplexer was built by a very good friend, who doesn't want to build
another one!!!
But yes, it was built from LDF7-50 1 -5/8 Heliax.

You can do a real simple repeater controller using some
555/556 timing chips in monostable mode.Look at any Forest
Mimms 555 cookbooks. He did quite a few decent circuits.
The 555 circuits decribed in a lot of those books are ok but
the best use of the 555 operation using all the

OK, story of my life :-).
I did as I said make one with just a few stubbs using small

I want to learn/run Linux, but have neither the time nor the available
equipment to setup a test box so I can become familiar before I jump in head
first.
Don't need to-just go d/l Mozilla Thunderbird.

Hehe,
I like your way of thinking Ken.
It was one of the main reasons I bought a Mac.
I have a new Intel based Mac that I run XP off a small partition, when I
need to use software the requires XP and the rest of the time I work in
OS-X.
No more viruses here!

Re: how to build a very simple repeater controller
How about using good ol' op amps? I like that approach because
almost the entire basic controller can be implemented using a
single chip: 2 op amps for hang time TOT, 2 left for audio
processing. Add a JFET for squelch audio gating

Hey Ken,
That is one way to set your deviation ...
Ok, I really mean it this time...this thread /dev/null

Any chance someone has a spec sheet on a HN462732g eprom?
I am really after the programming voltage.
21 volts is slow, and 25 whips it right out, neither smokes the chip.
Both seem to work, but I am thinking 25 volts is the right one.
SuggestionsComments?
