Tom, The TIA-recommended standard deviation for CTCSS is 500 Hz on a 16K0F3E or 20K0F3E emission. Most CTCSS decoders can reliably detect tone deviated as low as 100 Hz. Any deviation greater than 500 Hz can be considered excessive.
The HTX-404 is known for somewhat distorted (raspy) CTCSS tones, and that may be part of the problem. 73, Eric Lemmon WB6FLY -----Original Message----- From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of tgundo2003 Sent: Friday, July 18, 2008 5:56 AM To: [email protected] Subject: [Repeater-Builder] PL Problem I need some suggestions. It seems that my users that have newer Motorola "Astro" series radios have a problem on my Micor UHF repeater where the PL does not always open up their radios. It seems that it's only Astro-type radios that have the problem. I have the PL deviation set at 1K. It's generated internally on the uni-chassis TX PL board. I have 2 GP-300's, 1 MaxTrac, 1 GM300, a Yaesu dual-band mobile and a Radio Shack HTX-404 (with an MDC board installed in it! I actually love that little radio) and none of them have any problems decoding the PL. So what's up with the new stuff? It it really picky? what else should I check? Thanks!! Tom W9SRV P.S.- I told them all to buy old radios and be done with it. Besides the TX audio out of the new stuff sucks anyways, IMHO, unless you like listening to over-processed crap ;)
