Keeping in mind the normal Micor Squelch is a dual speed squelch
circuit for the audio and a second squelch (on the Squelch Gate
Module) circuit for the repeater cor/cos/tx function.
If you remove the chip from the original circuit and use only
it for cos/cor you no longer have the dual
It would be simpler and cheaper to find a tuneable or
frequency agile modulator. Jerrold, Blonder Tongue,
DX Antenna, Drake, and Olson are just a few of the
companies that make them. I've seen them for as
little as $20. Paul kb9wlc

Gentlemen,
Hello Jim,
Actually, I took my first super station master apart just last week
or so. I removed guts of the antenna, and replaced them with a 70CM
Diamond F718A vertical (11.5db). The entire Diamond antenna slid
right up into the shell of the super station master with room to
spare
On the one's I've removed, there wasn't a need to use a torch. Just remove the
screws at the top and
bottom and pull from the base. When finished examining the removed assembly,
it should slide back
together without too much fuss.

Yes, but I've found no use for the latter, as all repeater controllers made
today
I have a Micor Station 100 VHF that was used as a paging base. I removed the
backplane and installed a normal one and removed the cards for paging, and
installed normal base station cards. I completed the conversion (removing
diode) for allowing the receiver to operate all the time. Here is
It's a Unified backplane.

Meter the pins to both the audio squelch board and reciever board and see where
it is losing voltage while ptt is active (probably losing 9.6 volts somewhere)
then find 9.6v supply and tie it in directly. You should have been able to use
the paging backplane, I did on mine with outboard

Good Evening,
I have a site with a PD455-5 at 400ft that has failed me after 10
years of service. The reflected power has risen to about 10% of the
forward power, and coverage is drastically reduced.
Rather than installing another PD455-5 (which will most likely fail
in another 10 years due
I have 2 DB-420 on the air 450-470 split, Minimal SWR at 441.XXX and 442.XXX,
works great. One of mine is at 150' on top of a water tower and the other is on
top of a 322ft old microwave tower. The one at 322' has a 40+ mile range with a
good mobile (Dependant upon terrain, of course).

Well, I salvaged a DB420 from a junquepile at a two-way shop. The
pigtail was lightning damaged, so I took the top half, and
