To everybody that did the math for Tim, we are 1 meg split here in the
country of Texas.
Tim, I have some 1 5/8 hard line if you want to make a set of notch
duplexers, probably can get you the 80% done set from a buddy.

Boy, that seems excessive to me, even at 500 kHz. My hunch is that you'll
have acceptable performance much closer in distance. 1 MHz spacing was
mentioned which would obviously be even better.

Exactly my feeling. We've got low-band fire here with channels close-spaced and
high power TX and desense on an adjacent channel is rarely an issue. Usually
you've got to be within one or two blocks from the 1/4K before it gets noticed.

Thanks to all for the great response!
Well, since we are 1meg splits here -thanks Don-,
that should help some also. (I had looked up a
couple of repeaters around here saw .5 split,
so thought that's how it was).
Anyhow, it's just in the thinking stages.
Thanks again,

Hi Larry and Joe,
If your not wanting to do P25 the Master 3 is a good repeater but my vote
would be a Quantar or MTR2000. cant get much better than that.

Tim,
I plugged the same values as before into CommShop, but this time with a 1
MHz split, and the result is about 85 dB isolation, which can be met with
about 7.75 miles of horizontal separation.
The developer of CommShop was calculating distances that would result in NO
desense, using radios

Jeff,
I completely agree with your conclusions. The calculations of CommShop,
while remarkably close to reality for 2m, 220, and 440 applications, are
misleading at 6m and lower frequencies.

Hi everyone,
Just got few of this mobile radio, wonder if can be given
a good use in Ham radio, any info appreciated; or if any
interest in them let me know in direct reply.

Thanks.

Batlabs has some information on converting GTX / LCS 2000 units into
900mhz Ham use, but your model number doesn't match anything that
batlabs offers for conversion information.

On second look, your M10 is a 800mhz unit. No Ham radio bands there.
I'd look

Why do you not recommend the MASTR III in P25 service, Mike?
The newer ones do it with the appropriate

thanks for all of the good info.
As the receiver site will be solar ( there's
nothing electrical of any kind for quite a ways),
I guess the site should be pretty quiet.
Now start looking for some hardware.
thanks again!
