I was going to bring up TIA-603-C, but I figured it wasn't worth the resulting religious battles that would result in the Gaza Strip here. (GRIN)
I've also seen at least one (clueless) agency switch radios instead of simply demanding the manufacturer support their existing radios. Wasted of taxpayer dollars. "Stupid is as stupid does!" They could have demanded proper support or thrown the repeater manufacturer out. But there were other politics involved... if someone high enough up is a "Brand X" fanatic, it just means the taxpayers lose... What bugs me about the above, is that I'm just an Amateur and I can figure out that there's two prevailing standards. Why can't some "professionals"? Most get it, but there's still people out there who don't. Perhaps they shouldn't be working on Public Safety systems? Mmm? Just a thought...

TIA-603-C clearly states that there are two reverse-burst formats, 120 (AKA 240) and 180 degrees, and gives neither one special "standard" status. Motorola found that a 120-degree reverse-burst shift stopped the mechanical reeds quicker than a 180-degree shift. Now that DSP has replaced mechanical reeds, the technical aspect has lost its importance. Nate is correct that the shift is now a marketing ploy, wherein a newly-installed Brand X repeater will suddenly cause all Brand Y radios to have squelch crashes, and the Brand X sales rep will claim that the Brand Y radios use "obsolete" technology. That happened in my local police department when a Brand X repeater was installed; a large number of Brand Y radios were immediately replaced with Brand X radios. 73, Eric Lemmon WB6FLY -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of wd8chl Sent: Tuesday, February 03, 2009 11:22 AM To: [email protected] Subject: Re: [Repeater-Builder] Kenwood TKR-850 question <snip> > > Snuck a little Marketing into their programming software, did they? :-) > > Nate WY0X > > ------------------------------------ Yeah-especially since the 120 degree shift is the 'non-standard' shift.
