[Elecraft] K3 MCU 4.47 / DSP 2.73 BETA RELEASE

[Rick Bates]

I've been running this firmware for the last couple weeks and can confirm
that it kills the HRD<>AGC issue.  Well done!

K3 MCU 4.47 / DSP 2.73 BETA RELEASE (Pre-release evaluation and test)

New Features:

MORE ROBUST "GT" CONTROL COMMAND (AGC):

Some PC applications may accidentally turn AGC off, possibly due to a 
buffer overflow. The GT command format is now verified more rigorously, 
making this less likely. NOTE: PC applications should not send too many 
K3 "get" commands simultaneously, especially if a P3 is also in the 
system. Ideally they should wait for a response to each command before 
proceeding.


REMOTE-RIG K3 REMOTE CONTROL SUPPORT:

One K3 can now directly control another, with one acting as nothing but 
a front panel. This "remote rig" mode provides a nearly perfect 
emulation of the remote K3's display and controls. (Previously, front 
panel emulation was limited by the K3's legacy command set.) The 
simplest way to use this is to connect the two K3s together using a 
"null modem" cable at the RS232 ports. However, by using a computer or a 
third-party hardware (such as RemoteRig units) as an intermediary, it's 
possible to control a K3 over the internet or even a wiFi connection. 
Note that the controlling K3 can have a totally different configuration 
from the remote K3. It could be a K3/10 with no options, for example, 
yet it could still control a remote K3 with all options, including sub 
receiver, KPA500, etc.

To use Remote-Rig mode, set both K3s to 38.4 kb and connect them 
together via the RS232 ports (possibly using an intermediary device like 
RemoteRig  for control and Voip over local nets or the internet). Next, 
at the local K3, hold CONFIG until you see "TERM" on VFO B. If the 
remote K3 is listening, the TERM message will be replaced with a display 
that looks exactly like the remote K3's. (RemoteRig remote control 
systems with the latest firmware will do this automatically when 
connected to the control K3. Holding MENU is not necessary) From then 
on, the remote K3 can be controlled by the local one (the remote K3 can 
still be controlled with its own front panel, too). The local K3's audio 
will be muted. Both receive and transmit audio must be handled by the 
intermediary device (RemoteRig etc.)To exit Remote-Rig mode, hold CONFIG 
on the local K3 until you see "NORM" flashed on VFO B. The local K3 will 
return to normal operation. (Or, in the case of K3's and RemoteRig 
units, powering down the K3 will disconnect and power down the remote K3.)

Note: Elecraft will be offering RemoteRig radio remote control systems 
and interface cabling for the K3 on our web site order form shortly.
