Hi Ken,

It may be that way in Montana (one of my favorite places in the summer) 
but it's not that way in CA.  Output tones on a repeater are common here 
because of the repeater density (simple proximity, co-channel or by 
distance) and because summer ducting is common.

It's a poor mans noise filter.  Many of our 'communities' are larger 
than Billings or Helena (together) and the cities are obscenities. The 
RF noise floor can be rough.  Using output tones on a repeater makes a 
huge difference for users.

Even where I live, in suburbia, the local club uses an output tone on 
all of our repeaters (6, 2, 220, 440 and 900) and there is no
 other 2M 
channel user for 200 miles, rare here.

I'd bet that most metro areas of size (DFW, NYC) also use output tones 
on ham repeaters.  It's a simple means to lower user irritation from 
other radio systems.

We're starting to see more DPL used as well.

No, to the original poster, the K3 does not listen for tones.  I'm sure 
it could be added, but frankly I'd rather the team works on other 
things.  Use of tones on 10/6M (stock K3 feature) repeaters is common 
here and the percentage of folks using 2M transverters for repeaters is 
a small percentage of the whole.  There isn't much demand or return on 
engineering time to change the K3 to decode.

I use a commercial radio on
 6M repeaters (except when remoting from my 
station while traveling) and a dual band radio for 2M/440.  It's simpler 
in the long run and they have the decode features, plus I can listen to 
the local DX repeater without tying up the K Line. ;o)

73,
