They ( in line rf amps) are commonly used in mines. They are
bi-directional amps. Those I am familiar with split the vhf band in
half... one half goes each way with filters to allow bi-directional

The fajitsu radio is keypad programmable. The programming prom must be
hacked to go out of band. I do not know of a source for a hacked programming
prom.
Perhaps it is time to revisit this. I dropped it long ago due to other
equipment was available. You know the instant gratification thing. :)
Kevin,
If you figure a way to do it, a lot of people would be interested.

OK Neal,
I share 53.41 with N2ROW and it's never been a problem except for a few
band openings. I'll let you know when 53.71 is on the air up here in
Connecticut.
I have a very small amount of desense on the 6 meter Mitrek also. I'm
not sure yet if it is internal desense, I'm running the
I have looked at the article dealing with the antenna relay while
converting a base amp to a repeater amp, 4 options are given. I was
wondering if just unplugging the Rx cable and plugging in the amp cable
into the Rx jack and disconnecting the antenna relay coil would be
accepable. This could
No, your transmitter won't be connected to anything. At least if I'm
understanding your question.

With no power to relay, the ant. would go to the Rx. If I take the Rx cable off
and replace it with the amp cable, the amp should go right to the ant.

Maybe we are talking about two different things. Are you talking about an
external relay, or the relay that is soldered to the PA low pass filter board?
The relay on the PA low pass filter board has two jacks next to it. One
connects to the antenna, the other to the receiver. The PA is
Your right, back to drawing board, thanks, Bernie

With no power to the relay, the path is from ant port to rx port.
Tx goes nowhere.

I like the 4 bow tie style antenna, some people call them fly
swatters, About $40. and I use a Channel Master Spartan 3 mast mounted
pre-amp.
Also I have seen retired TVRO parabolic dishes used for UHF TV
reception at a translator sight that was 80 miles from the 100 watt
transmitters that fed
Parabolics used to be the thing for UHF years ago. I remember my Dad having
one in the late 60's

Morning,
I have a couple of M-10 radios run together with a 12VDC fan keeping
them cool in the cabinet. However the power block has them all run into
the same line fed by the power supply. You can hear the noise of the
fan when you key the repeater. Would a filter help this on the positive
What I can not remember was if the program prom was band specific. I will go
look. I have a vhf and a couple of UHF rigs. I always just left the
programming proms in the radios I used. If they are in fact different then
yes the limits are in the programming prom. I had not thought of snooping

Peter,
Most DC fans use a Hall Effect device to develop the commutating signal that
ultimately drives the fan. Many, and perhaps most, such fans are designed
to meet a price target, and their manufacturers devote very little effort
toward reducing or eliminating EMI. Other manufacturers, such

Having the DC fan get into the audio is a common problem for DC fans. It can
be eliminated with filtering but usually an easy fix is to run the fan from
another DC source, like a wall wort.

Well I already cut the hole in the side of the cabinet so I guess its off to
rat shack for a AC fan. The DC one is just to noisy to be heard on the
