Since so many Ham repeaters are on sites free and at the blessing of 2-way companies or gov services, etc often when one does find an intermod or other interferring problem one just has to live with it.
Trying to go to a site administrator and require one of his "paying" customers fix a problem, which is often not illegal in nature, is received with "well you don't like the site move". Also if you become a pain they will do the moving for you. I've seen Hams try to command issues thinking they are in control because they have a piece of paper from the federal government. It is good to find the problem yourself, but fixing the problem is another issue. Tone is a good fix for some of these. 73, ron, n9ee/r >From: [EMAIL PROTECTED] >Date: 2007/08/28 Tue PM 11:29:35 CDT >To: [email protected] >Subject: Re: [Repeater-Builder] Re: subaudibe tones.. > >At 8/28/2007 16:01, you wrote: >>Bob Dengler wrote: >> >> > One concept that really helps in this area is CTCSS tone frequency >> > standardization, IOW tones by region.
