Vertex Standard VX-2200 and 4200 series radios can be channel changed via BCD
addressible pins from the rear sub DB15.
We utilise a UHF link radio (VX-2200 or 4200) to send 5 Tone commands that
can be addressed via a configurable BCD output that can change the frequency
and of course pass

Hi,
New member here. Thanks for allowing me to join.
Our club has acquired some large lead-acid 12v batteries we would like
to use to back up our repeater in emergency situations. Does anyone
know of a good (but simple and inexpensive [we are a very small group
in a very small town]) circuit
CPI Communications has several Tone Remote products as well, but as
mentioned the multi-channel control equipment is mainly for Motorola and
Kenwood. That said if you radio can support BCD control you might be in
luck.

Hi all you know they say there is no dumb question unless you didnt
ask it and messed things up so here goes .I am wanting to make a cheap
repeater system for 2 meter and I really need some input on how to put
one together and also once its built is there a special licence to
operate it?Thanks

Ron,
Yes, as a matter of fact, we are using half-duplex transceivers for each
link, and some links go through multiple hops which makes your 24
input tail beep generater method unusable.
We do infact put a tail beep on each transceiver (only when the received
signal is coming in on the

Hi ALL
I have an MFJ-2040 Autopatch repeater controller. I deperately need the

what equipment are you using now?
astron makes a automatic switch (it automagicly switches from AC to DC with
loss of AC)
there are a couple other makers, I'm sure.
you'll also have to consider battery charger(s) too.

I have had good luck using a pair of diodes to isolate a power supply
from a charging circuit. I essentially have a Statpower 10amp battery
charger (specifically designed for the flooded cells I am using). The
batteries float on the charger voltage when the AC power is available.
The battery
A really simple circuit that I have used in a couple of repeaters uses
three power diodes and a resistor. Select diodes that will carry the
repeater load at about 50% of their rating.
Place one diode in series with the power supply to the repeater. This
one keeps the voltage from backing up
I have to agree with Dave. Using the proper charger or power supply for
keeping the batts up. I have my batteries housed in a stainless steel
enclosure that is anchored into concrete outside my ham shack. I learned the
hard way about using the proper charger... I just tapped into my repeaters

One source of (almost) free diode pairs is any alternator shop. The
common configuration of diodes in an alternator has three on a
plate, and two plates. One plate is common anode, the other plate
is common cathode.
The common failure mode is that one diode opens or shorts and the

The simplest way is just to get the IOTA supply and
float it across the battery. Thats it, nothing else
needed. Get an IOTA big enough to power whatever you
have, and still have some left over for charging. You
don't need (or want) diodes, resistors, or relays.
It shouldn't be that easy, but in
Danny,
If your batteries are flooded wet cells, as distinct from sealed (VRSLA or
AGM) types, you should take care to vent them to the outdoors. Wet cell
batteries also require regular monitoring for electrolyte levels and
specific gravity.
