Sparksdr; Flex Radio Cw Zombie Mode - Lynovation CTR2-Dial Operation Manual

SparkSDR

SparkSDR (https://www.sparksdr.com/) has limited support
for MIDI control. It doesn't support buttons, only the dial
and knob controls. To map the Dial's encoder functions to
this program, first plug your Dial into a USB port on your
computer and open SparkSDR. Once you have the program
running, click on the General Settings menu and select
Midi. You should see CTR2-Dial 0 as a MIDI controller and
turning the encoder should display MIDI messages from the
controller. To map these messages to a control in the app
simply press the + icon and enter the Control number
shown in the Last midi message: window in the Control
column. Then select an Action and set the Scale and Offset
required for that control. You may need to play with these
values to get the control action you want. Check the Inc box if you want the value from Dial to be added
to the current setting of the control. This is only used with the vfo control. This screenshot shows the
settings I use.

Flex Radio CW Zombie Mode

If you plan on using your Dial with a Flex radio using remote CW keying there is an odd problem in Flex
firmware where the radio can go into CW zombie mode. This happens occasionally when connecting
and disconnecting multiple clients to the radio that send remote keying commands (at least I think that's
what causes it).
In zombie mode the radio looks like it is transmitting CW, the light on the front panel turns red, the TX
icon turns red, the MOX button turns blue but no RF carrier is generated or displayed on the
panadapter. The only way I have found to get the radio out of zombie mode is to disconnect all clients
and power cycle the radio.
