I don't know about IOTA switching supplies, but my Newmar PM-12-70
switching supply causes birdies all through my HF gear here at home.
I also used a bank of five brand new 12V batteries tied to a Vector
VEC1093A battery charger instead of the Newmar, and that charger as

Hello all,
I am Allen, senior radio technician, working in Africa, new member.
I have extensive experience in trunking systems, but not very good
with conventional.
I would like to know the best method to link 4 repeaters (conventional)
to work as one channel. Are link radios the best method?
I finished the last tests of the bad Maxtracs saturday and they are
one hundred percent!! A year ago when I started this I was unsure.
I have alot of other responsibilities and could not devote full time

Hi all,
I'm involved in a large linked system (about 15 repeaters at present).
One of the goals of the system is that, regardless of the repeater, the
user should hear a different courtesy tone for each site in the system.
I'm just curious, are there any large link systems that do this, and

Each set (the pair as it were) on this db420 is 90 deg.s from the one

Allen,
One methode is to use a hub repeater and have a transceiver at the
other repeaters linking to the hub. This hub can be one of the
repeaters in the system (one hub with the others having tranceivers
on this hub freq) or have a dedicated hub repeater on another band.
The least expensive

In the Cincinnati, OH, area is the 145.19 with many linked repeaters

As with most all duplexers the cabling is cut to length to get best
performance so would be best if had correct cabling, but this might be

I've used lots and lots of the 66s to go down to 145/146/147 with no

Seems their commerical band is in the 140-150 range unlike the USA in
150-170. Both tuned with no problem.
I will not say all 66s will tune down,

On the 220 cavity conversion this would be excellent posting on the
board info sheets. Might consider giving it to the board moderators
or posting in the FILES section.

If you were going to buy a new repeater/base... you might just want

Actually I have several 56 splits. When I ordered the xtal, I ordered for high
side injection, and it does not want to tune up real well. Put a 147.78 LSI,

split and see if it will do any better.

447.900 versus 444.800 is a LONG LONG LONG way to go. Or did you really
mean 444.790 versus 444.800? That sounds more realistic.
There is a fixed cap, typically in the range of 20 to 39 pF, located more or
less behind the trimmer. I can send you a pic if necessary to confirm which
cap it is.
I beg to differ. I downloaded the brochure and data sheet for the TKR-751,
and it appears that it is intended for the European market, since it has the
5-Tone signaling capability. It also is designed with the low end of its
tuning to be 146 MHz, which doesn't help Amateurs who need a repeater

Ken,
Thanks for the quick response. I made the distinction about the TKR-750K2
because some readers of this list are used to radios that can be programmed
out of band with no hiccups, which list may include the TKR-750K1. Other
brands or models of programmable repeaters- the Motorola MTR-2000
