Hi Chris,
> can one remotely activate a repeater without tones?
> Say: click PTT three times within 3 seconds and repeater is up. > click PTT four times within 3 seconda dn repeater is down The S-COM 6K and 7K repeater controllers have had this feature for
many years due to our involvement in aviation (mic clicks are
used at unattended airstrips to bring up beacons and landing lights).
The 6K and 7K have been discontinued, but the feature will be
kept in the new 7330 controller.
Frankly, there hasn't been a lot of interest in this kind of feature in the
ham market. There was some interest in Long Tone Zero (LiTZ) years ago,
but that feature requires the user to have a working DTMF
encoder.
I must admit I like the idea of allowing a user to get some kind of
emergency attention by simply clicking the mic on the repeater input
without needing DTMF, CTCSS, or anything else besides a radio. The
controller could send a paging tone or DTMF sequence over the air,
switch the repeater to carrier access, or whatever it takes to get help.
(The number of clicks, their duration, and the overall window time are
all programmable to minimize accidental/noise activation.)
73,
Bob
