[Hamlib-developer] CTCSS

[Dale E. E. <de...@w-...>]

Nate,

Thanks.  After I RTFM yet again I finally found the part I'd been
missing.  Tone is what I transmit (usually to a repeater) and both
CTCSS and DCS are what I receive/decode.  1750Hz is an once
only burst transmitted to a repeater to open the squelch (European).

Got it.  The manual says in fine print, "You can select a tone
frequency independent of a CTCSS frequency."  So I can TX
using tone=103.5Hz and receive using CTCSS=88.5Hz.  The
1750Hz is a menu item which may be turned on/off.  This all may
seem of dubious value but I think it is primarily indended for use
with a handheld while controlling the TS2K remotely (It's nice
walking around talking on a HT through the base rig.  Kind of
like a portable phone or cell phone--bleh!)  Either that or for
cross-band repeater operation.  I've only played with it a little
but it was fun!

Another concern was that Hamlib controls tone via a parameter
call (rig_set_parm()) but CTCSS and DCS each have their own
functions (rig_set_dcs()).  This is a confusing interface and users
(plus at least one developer) will complain.  We should move them
both to the same place.  Either all three are parm's or all three are
functions.

Since CTCSS and DCS cannot be used at the same time they may
share the same variable.  Tone on the other hand may be used at
the same time and should have its own variable.  (How come I'm
always on the other side disagreeing with everyone?!)   :)

73's all.  Thanks for the information and patience!
