[Elecraft] K3 current status of TX INH?

[Barry N1EU]

There was much discussion in Nov/Dec of using the Aux I/O Pin 7 TX INH line
as part of a qsk keying loop interface with modern amplifiers (e.g. Acom). 
Wayne indicated in December that the firmware change was being made (see
http://mailman.qth.net/pipermail/elecraft/2007-December/079205.html)

Can someone confirm that selection of OFF/LO=INH/HI=INH  is now in
production firmware?

I believe that Acom amplifier interfacing will require setting it to HI=INH
(i.e., a low level will enable tx).   Is there a convenient +5V source for
wiring the required pull-up resistor to Aux I/O Pin 7?

To date, has anybody actually implemented this in their K3 - amplifier
interface and can report on how well it is working?


Thanks/73,
Barry N1EU
