[WT-support] external interfaces signal behavior

[Bob Wilson, N6TV]

First note that Win-Test lets you control three types of switching from the
keyboard:

(Default keys shown, you may use DEFINEKEYS to change this):

Swap TX *and* Data Entry Focus (also Primary/Secondary radios):

[*] (asterisk key on numeric keypad)

Change RX Focus only:

AltGr-A (Primary)
AltGr-S (Stereo)
AltGr-T (Secondary)
AltGr-L (Latch mode, listen to opposite radio only, during TX, only works
with microHAM control protocol?)
(If you don't have an AltGr key, use Ctrl-Alt instead)

Change Data Entry Focus only:

CapsLock or Shift (enable via WT menu:  Operating)


If signals on TX Focus (labeled "Active Radio"), RX Focus ("Headphones
Control") , and Stereo ("Stereo RX Audio") pins make your home brew SO2R
box do the right thing, it is working properly.

Yes, first you want to check for dupes in the secondary radio window, (e.g.
press CapsLock, data entry focus change only, not TX focus), then *at the
right time*, you want to transmit to make a call.  TX focus doesn't switch
to secondary radio until you press a message key.  This is a problem if you
want to make a call on the secondary radio using the paddles.  In that
case, the only way to do it is is press [*] (or use two paddles, one for
each radio).

The design, which has been difficult for many to get used to, is to only
switch TX focus "immediately" via the [*] key.  This lets you continue to
CQ on Radio 1 while you are entering a callsign in the secondary radio
window.

Yes, if you are in Stereo mode, then switching RX focus Left and Right
should has no effect at all.  Primary radio is always on the left,
secondary on the right.  This presents a usability problem when you swap
Primary/Secondary by pressing [*], because then the primary radio could be
to your right, but you'll now hear it in the left ear (if stereo is
enabled), which is backwards.

Yes.  The stereo on/off pin overrides the RX focus pin.

It's true that if you press AltGr-T (listen to secondary only), then
AltGr-S (toggle stereo ON) then AltGr-S again (toggle stereo OFF), you end
up listening to the Primary radio only instead of the secondary.  I don't
know if this is a bug, or working as intended.  Only Win-Test SO2R designer
CT1BOH knows for sure. ;-)
