Obviously the 'no timing' situation is not completely traumatic for the 
conversational use of the repeater, as there is no widespread comments 
or negativity about it.

The RTCM is a good idea and a good design, but with the Simulcast 
transmit not functioning, and no apparent developer activity there's 
just not enough light at the end of the tunnel to commission it everywhere.

It seems to me that analog simulcast transmit is never really going to 
sound right.  I feel uneasy about the relentless approach of digital 
audio into ham radio, but maybe the dream of zero-handoff multi-rx 
multi-tx systems means 'digital' and we're stuck with it. I'd like to be 
proven wrong on that.
