Sorry about what may be my confusion about this option but I've been
following this thread and previous threads concerning the use of TX INH
to support the use of keying loops provided by many amps. My amp
provides for the use of a keying loop and I would like to continue to
use the loop function whenever my own K3 arrives. Wayne's description
of the latest firmware makes me wonder if it can be used as part of a
keying loop. Here is what I understand from what he has posted.
The TX INH menu can be set to HI=INH (a logic 1 inhibits transmit) to
accommodate the low signal that is passed thru the amplifier when it is
ready to be hit with RF. Sounds good so far but then Wayne goes on to
say that when the K3 is in its inhibit state "Using transmit-start
switches (XMIT, TUNE, ATU, M1-M4) results in a brief "TX INH" message on
VFO B. The key, keyer paddle, /PTT, and TX via PC commands are all then
nonfunctional." In addition " the TX LCD icon flashes slowly". If
all of these functions are inhibited then there is no way to start the
keying sequence and to send a keying signal to the input of the amp's
keying loop.
Am I missing something here? As currently implemented it does not
appear to me that the TX INH will allow the use of a keying loop for our
amps. But I can well envision its use in a multi-setup where a 'hard'
inhibit is desired.
