Hi all,
I've just added the TX INH function and its associated menu entry to
the K3. Just in case you have no clue what this is: it provides a way
for an external station controller to determine which of two or more
transceivers can have access to resources such as an amplifier. It's
typically used in multi-op contest situations.
By popular demand, the TX inhibit level can be *either* active-low or
active-high. Thus the TX INH menu entry has three settings:
OFF (no TX inhibit)
LO=INH (a logic 0 inhibits transmit)
HI=INH (a logic 1, 5 V, inhibits transmit)
I'm testing this feature right now, and it should be in the next
production firmware release.
Thank you, Wayne, that's excellent.
One final detail: if any external device is using the TX INH input as a
"Clear To Send" handshaking signal, then hopefully the CTS signal will
be interpreted as "Clear To Send NOW", and the K3 will respond with the
absolute minimum of internal delays.
(Sorry to beat this horse again, but I'm asking now because it affects a
project that is already in the detailed planning stage. When the K3
arrives, I'll measure the TX/RX delays myself, of course.)
