Elecraft K2 K3 KX3
TRX-Manager supports the Elecraft K2 K3 KX3 transceivers.
Settings (Setup)
It is recommended you set up the Transceiver for the highest practical speed (38400 bds ) ;
it is necessary to restart TRX-Manager and the Transceiver after each change of the
communication speed. Please check KPA3 or K2/100 is the 100W module is installed
(uncheck KPA3 or K2/100 if you use a K3/10 or a K2/10 or a KX3 alone).
K3/KX3: TRX-Manager uses the extended format (K22 or K31) of the rig and the normal
auto-information mode ; consequently, it is highly recommended you configure
your K3/KX3 for CONFIG:AUTOINF = nor (TECH MD required). You may also prefer using your
K3/KX3 and TRX-Manager with CONFIG:SW TONE = OFF.
With the KX3, if you don't have the KXPA100, set PA MODE OFF in order to reduce the flow
of data on the RS232 port.
If you use TRX-Manager through an RS232 Serial Server (via the Internet or Intranet) or
through the Larry N8LP's LPBridge program, you may have to check the LPBridge, Serial
server option in Setup (not always) ; you can leave LPBridge, Serial server unchecked
(default) if it works this way with LPBridge or your serial server since the serial server
option limits the TRX-Manager's ability to detect state On/Off of the Rig and accuracy of the
TRX-Manager's S-Meter. See also: Alternatives to the remote control function, Disabling the
dual control mode.
About LP-Bridge
LP-Bridge is NOT required with TRX-Manager: use the Synchro function (K3 Protocol) to synchronize
TRX-Manager, your Pan adapter and PowerSDR-IF Stage or Nap3. Generally, this setup works much
better.
If CW Internal is checked in Setup (Internal Electronic CW Keyer of the Rig selected) you can
use the CW terminal to send either CW PSK of FSK; but please note the CW Internal option
overrides the choice of keyer made from the CW Tab (i.e if you use Winkey, do not check CW
Internal!). However, whatever your choice, it will be always possible to send CW/FSK/PSK
using the K3/KX3 since K3/KX3 levels window includes a small terminal (see below: data
mode)... (what makes setup very flexible but not simple to understand!).

K2
A special window ( Transceiver/Levels) provides emulation of the Elecraft K2's front
panel. The display of the window reflects the display of the rig with some limitations. To use
this window suitably and to have the best possible interactivity with the transceiver, it is
recommended to simultaneously open the Monitoring window.
