In addition to the other radio brands and models listed by
others,

Welcome to the world of 6 Meter repeaters.
They can be a lot of fun. In Missouri you are a little better off frequency and
duplexer wise due to your 1.7 MHz split between transmit and receive
frequencies.
For radios it depends if you are a GE or Motorola person. If you are a GE

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
TMARC (MD, E-WV, N-VA)
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.

Local Band plans are fine except when skip opens up on 6 meters and
nobody can win or utilize an interference fight. Look to see how many
domestic users are left in low band vhf in relation to say 30 years ago.

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 other

IF is the same frequency as the main (FM) receiver IF.

Actually it is your local coordination body that counts. I just

Hi Reid,
It's not the same site you're thinking... but I've been
able to make one play from your old repeater site. But
a lot has changed since you were up there.
You needed to get rid of the silly gear and get a
heavy duty Midland Mobile... :-)

skipp, I could never get my 6M rcvr quiet on the site you refer to,

to on-channel grunge, besides a mix from the CHP LB nearby also. Ah well!
