Hmmm... using that logic, you can have the most reliable repeater by not
putting it on the air at all. That way, it will last forever. :-)
(provided it's not using tubes)
Actually, I would tend to think that like us, periodic exercise isn't a
bad thing for a repeater. It will help keep the caps

This is an asenine statement,if the repeater is in heavy use,you know for
sure
Does anyone have any use for the tone elements like the old Motorola Pageboy
used before I toss about 100 or so of them ?
They are part number TLN 67098. They are from about 300 to 500 hz in
frequency.

Anyway... I don't understand the intermod software's math that Ken
happened to be using. :-)

Ed,
You have nailed it exactly. It's a classic case. Circulators on each
transmitter should help but any rusty bolt, moisture, or loose hardware near
the antennas can contribute to the problem. This is not a good frequency
pairing and will always be giving problems.

The individual elements on a Signals array are each 50 ohms. Those elements
have a larger diameter element where the feedline attaches, (up to the
bend). I've tested those and can confirm. However, I've never tested one of
the single Decibel elements. Now, please keep in mind that I am talking

The 147.225 has input 147.925 and the 146.925 has input 146.325.
Actually, your input should be 147.825 for 147.225 out.
To be honest, I didn't
A=frequency 1
B=frequency 2
Formula for your frequency products is 2A+b, 2A-B, 2B+A, 2B-A. Simple
math!

Minimum distance should be at least 90dB to 100dB signal difference. If you
have enough room on tower, and coax, 100 Feet should get you more than
enough.

I think the suffix behind the TLN is 4 digits...
If I have two receivers A and B. Receiver A has a sensitivity of
0.25uV for a 12dB SINAD and Receiver B has a 0.35uV, which has a
better sensitivity? is it Receiver A?

If they were both measured at 12dB Sinad, yes.
The lower the number means that it takes less
signal to achieve the required spec (12dB Sinad)

I am looking for a continous duty amplifier for my 2 meter repeater,
transmits at 146.925. Must be for a 19 rack mount. Looking for
something in the $300.00 and below price range. Let me know what
you have, shape, cost, make and model, fans or no fans etc...
Thanks.

If the value for Receiver B is also based upon a 12dB SINAD, yes,
Receiver A is more sensitive. Expressed another way, Receiver B
requires 40% more signal than Receiver A to achieve the same degree of
quieting. Even so, a value of 0.35uV for 12dB SINAD is satisfactory for
most applications.
