I agree with Joe and Nate. The Quantar shares audio and data between modules on a digital SPI bus, and there is no provision for adjusting the CTCSS sensitivity. Hello? This is Motorola's flagship station, and a high-tier one at that. Pardon my sarcasm, but we should not lower the bar to accommodate Amateur-grade equipment! Is the "group" a bunch of licensed Hams who believe that the Yaesu VX6 is a top-quality rig? Okay, okay, the sarcasm switch is now off.
When the statement was made that the CTCSS deviation from the VX6 portables seemed to be very low, I hafta wonder if the bandwidth setting of the service monitor was not set to include the 5-300 Hz bandwidth, rather than just the voice 300-3000 Hz bandwidth. Hey, I've made this mistake myself, so I know it is possible. When my R2600D service monitor is set for 300-3000 Hz bandwidth (its default), CTCSS deviation looks very anemic. As well it should! I think the Yaesu VX6 radios are sending trashy CTCSS tones, and the Quantar is properly ignoring them. That's my story, and I'm sticking to it. 73, Eric Lemmon WB6FLY -----Original Message----- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of MCH Sent: Wednesday, September 26, 2007 11:26 AM To: Repeater-Builder@yahoogroups.com Subject: Re: [Repeater-Builder] Re: Quantar and PL I doubt you would get far with Motorola since the problem is that Yaesu is not using good engineering practice by not filtering the TX audio to remove CTCSS components. I would start with Yaesu asking them why not. Joe M. Nate Duehr wrote: > > On Sep 26, 2007, at 7:09 AM, Al Wolfe wrote: > > > So the questions remain: Is the Quantar PL sensitivity > > adjustable?
