Nate, A hang time is good. How long well it depends. Many repeater users I know use it to govern the time between transmissions by letting the repeater drop before they take it. They do this to allow breakers. Some think it resets the timeout timer. If long say 10 seconds would be slow QSO.
Most controllers allow for programming the hang time. I still keep mine at 3 seconds. Some want no hang time. Cycling of the tx is not a problem. Might be with tube or big PAs. If it were a problem then many rigs would die quickly especially HF CW rigs, hi. I'm not sure what you are saying about control link. One must still be in control of a repeater, just does not have to be at the control point as with other Ham stations. 73, ron, n9ee/r >From: Nate Duehr <[EMAIL PROTECTED]> >Date: 2007/11/07 Wed PM 06:04:30 CST >To: [email protected] >Subject: Re: [Repeater-Builder] Part 97 question reference to Repeater control > > >On Nov 7, 2007, at 4:46 PM, MCH wrote: > >> That's what I'm seeing, too.
