Not there yet. I don't even have a 6 meter rig. I am looking at getting the
Yaesu FT-8900R for my first 6 meter. Any ways, I have built Master II
Repeater, Micor Repeaters, and Lots of Mitrek Repeaters. So I am more
familiar with Motorola than GE but I can handle both. Never built anything

The 1.7 mhz is the new aloted band
plan split for 6 meter band in the US.
Ohio is 1MHz from 52 up,
The FCC has only enforced that which is clearly spelled out in the
standards and nothing else. No regional or splintered band plans exist.
There may be mitigating circumstances such a pavepaws etc that can have
a detrimental effect on continued operation or putting up a repeater.
That in no
They HAVE enforced local bandplans. That's a fact. They have also
threatened many times anyone not following them who had better have a
darned good reason for it.
Here is an interesting quote from one ham with an opinion...
Band plans are voluntary in nature, (he) acknowledged in each of the
repeaters
to switch to a wider split. Sure would make duplexers work better.

You are incorrect. The local coordinating body will tell you the only

Yeah-heh-Ohio still has a couple of grandfathered repeaters using
240KHz. In fact, the biggest 6M repeater in Ohio is one of those, been
there since the early 70's...oh, and the input is 52.92...

Yes, it's for D-STAR, but it's mixed with the analog repeaters. So, you
go from 2 spacings (12.5 kHz 25.0 kHz) to 20 spacings (from 2.5 kHz to
25 kHz) from existing repeaters.

That's odd, as the FCC HAS enforced local bandplans in the past. Feel
free to tell them they didn't have the authority to do so.
They cited the persons under the good engineering practice rule.
As for your statements about not being coordinated, read my post again.
I addressed that, and said
My CommShop software calculates that an isolation of 78 dB is needed for no
desense. Bear in mind that this software makes a number of assumptions in
computing isolation values, so don't treat the answers as absolute.
Tube-type PAs can get by with much less isolation, due to the lower noise

Dave,
I think his point is the FCC doesn't set policy on repeater splits. If
you're not going to get coordinated, you can make up anything you want,
but in an interference dispute with a coordinated machine, you'll lose.
I've often wondered if it would be possible
That's news to me. I've run a 6-meter repeater for years and had involvement
for years before that. The split in our region is 1 MHz, although you can
get some pairs at 500 kHz if you really want one there.

That is still correct. I just checked. Arrl has made some suggestions.

As others have mentioned, there's nothing that makes a particular
repeater split a U.S. wide
(but may be for the
antenna!). I've seen listings where the single site is on 1.7 MHz split with
an offsite receiver on the 1 MHz split.

Not true. The FCC has upheld local bandplans. Coordinated or not - they
apply to everyone. It doesn't even have to be a repeater issue.
True, as long as no interference is created, they likely won't get
involved, but if there is, and one user is operating according to the
bandplan and the
receiver on the 1 MHz split.

True ...
Before 6 meter repeaters became really popular in Oregon - last
several years - DB Products 40-50 MHz cans were going for $25 or
$50 at the local swapmeets.
