I should have said a repeater radio cost over $1000, but then again I

I paid $400 for the IC91AD. This is about the cheapest one can do

Sounds as if this was not an issue.
Your statements are worth saying again.

After reading all of the recent post about different types of coax
that are acceptable in duplex service, I made my self a list. Then, I
thought that this might be helpful to others. Here's what I came up
with so far. Please add any that I have missed.

Bob,
A PL259 or SO239, a good one, is good to 500 Mhz although at UHF, 440, I
would recommend N connectors as you suggested.
One problem with UHF connectors, PL259, etc, so many are made for CB.
The cheap 10/$10. Good for HF, but that is about it. Guess ok on 6.
Motorola and GE used UHF
I would recommend not using a 12.5 kHz spacing freq in this case of a
control receiever, a receiver that is only 12.5 kHz away from your
regular repeater input.
With typical good FM analog receivers these would both have overlapping
passbands and an input signal on the repeater input would
I have a digital MSF5000 that normally works OK. From time to time it
stops working and L06 is displayed.
Resetting the station brings it back to operation.
My service manual does not list error code L06. Does anyone know what
it means?

One can get push button switches that latch on when pushed/latch off
when pushed again. IF you want just digital mode while switch is
pressed then no problem. If you want to make sure the radio stays in
analog until commanded requiring the op to hold during digital then a
momentary switch
According to my info, there is no set of error codes
beginning with L. There's A, d, E, o, and
U. The only 06 code is A06.
When the station powers up, does it display 8.8.8.?
This would be the way it does an LED test. Perhaps one
or more segments are missing from the display. I

I first became enlightened when someone gave me several lengths of RG-393

station show RG-400 - taken during testing). Once I did some

John,
Ebay is your friend here. Look for Mini Circuits there and you will
find dozens of suitable units. I've gotten several two-way splitters there.
Typical and theoretical loss is 3 db, not usually a problem following a
preamp.
The TV type splitters do work as well but can be a bear

While that might work okay, here they have frequencies close to the
repeater RX frequencies I might use marked as one way links or repeater
inputs.
My thought would be using a diplexer of some kind.
Of course, I also thought of a diplexer to use the antenna for a low
level 2 meter
There must be some point on the device that will show power when enabled?
Maybe pick off that point and either attach an LED, or maybe a relay
connected to an LED... or maybe a DPDT switch, one side connected for your
indicator.
Just thinking out loud.

If your repeater situation is like most, antenna not on 5000 ft

Ron,
I don't think anyone was proposing putting the control RX 12.5 kHz away. I
think the intent was not .5 channel away, but at least 1.5 channels away, or
37.5 kHz. Some sensitivity could be lost, and there may be a little desense
moving off the transmitter side's notch, but may be workable
