As alternative software to Simon’s great RC tool for controlling LinearAmp Gemini HF-1k and Gemini DX1200, here my latest project.

• Power levelmeter with peak hold (700ms)

• radio name readout (OmniRig, TCPIP cat, TCI and UDP)

• connects to Omnirig , TCPIP-cat, TCI (by Expert SDR) or via UDP (automatic band switching)

• isAlive function for Radio-Connection and Amplifier connection

• automatic reconnect, if connection (radio or amplifier) is back online

• no popups or msgboxes to click

• configurable timeouts for send/receive/connect and for queries to the amplifier

• if programm is running (or not), you can call “GeminiMultiControl.exe /standby” or “GeminiMultiControl.exe /run”… If application is running, it executes the commands, if not it starts up the application.

• all Gemini basic functions (Antenna select, band select, power select, trip reset)

Installation notice:

The download file is a setup-file. It places the software into c:\program files\gemini multi control, creates a start-menu entry and a  desktop shortcut.

The software is compiled to run on Windows 10/11 64bit.

Amplifier-Connection: Please note that the TCP-Server in the Gemini amplifier only allows one connection (you can use either Simon’s tool or mine. Both at the same time is not possible). 

OmniRig: If you use OmniRig, and OmniRig is running with administration-rights, you have to start Gemini Multi Control also with administration-rights, otherwise you will not be able to connect to OmniRig.

TCPIP cat is tested via Thetis 2.9.0.8 MW0LGE. Please checkout latest version of  Thetis: https://apache-labs.com/community/viewtopic.php?f=9&t=3817

TCI is tested via Thetis 2.9.0.8 MW0LGE and SunSDR2 pro (ExpertSDR3 1.0.4 beta)

Please note:

I wrote the software for my purposes. It is not an official tool from LinearAmp. Everyone is free to use my remote control tool. If you don’t like it please use another amplifier remote software.
If you have any ideas let me know. If it makes sense for me, I’ll consider implementing it.

The software is 100% free of charge, no trialperiod or whatsoever. Gemini Multi Control runs on Windows 10/11.
If you like it, a donation will be much appreciated!

1.0.2

• a couple of bug-fixes

• added always on top function

• added buffer for commandline arguments
  Now you can first start the software with the argument i.e. /run. The software starts up, connects to radio and amplifier and executes the run command. The buffer alive time is 30s. So if there is some problem connecting the amp on startup of the software, it will only execute the command if its not “older” then 30s. 
  This 30s buffer is also active, if the software is already running while you call the /run argument. So if the amp is not connected, it will only execute the command if its within 30s. 

1.0.1

• Initial Release

Have fun with it!
