OTRSP utility for SO2R contest mode

It is a simple utility I developed to use 5MContest and my FlexRadio 6300 in SO2R mode.
All Flex 6000 rigs implement the OTRSP protocol and my program simply monitor the active (focused) window switching from Radio 1 to Radio 2 as the operator select the related window.
You can also configure audio for listening only to the TX focused radio or you can select the in stereo mode listening to Radio 1 on left speaker and to Radio 2 on right speaker. In addition it supports reverse stereo audio (Radio 1 to right speaker and Radio 2 to left speaker).
Configuration is quite simple: you need to set the beginning text of each window and the com port that support the OTRSP protocol.
Actually you can use with each rig that support OTRSP protocol and each contest software that use a separate window for Radio 1 and Radio 2.

A RemoteQth Cable Adapter for Prosistel Rotator

A network control program for Antenna Rotator

Two nice software utilities you can use to control your antenna rotator from PC (Windows, Linux and OsX) and Android (5.0 or later) smartphone. At the moment they only work with the Prosistel-D serial protocol (the only one I can test). More informations here.

A SW Keyer for remote operations

Updated 2017-10-23

This is a simple tool based on the "Morse Code Iambic and Semi-Automatic Keyer" from the Morse-Code-Tools projects.

You can use your key, bug or Iambic Paddle stright connected to your personal computer without a hardware morse keyer. I modified the code to send commands over the network to a remote actuator connected to the Key Line of your rig. The actuator can be a Arduino board (like in my previous project Remote Morse Key) or, if you already own a Raspberry PI 2/3, you can install a simple shell script (more details in Remote Utils section).

In addition, if you are a FlexRadio 6000 user, you can solve the issue of the Missing CW Tone when you use the radio in Remote Mode.


The Arduino Flex controller

Updated 30-09-2017: - Released 2.0.19 version of Libraries and Controller - Added  support for SSDR 2.0 release.

N.B.: version 1.x of both Arduino controller ibraries will no longer be supported



Arduino Flex Controller is a DIY project. In these pages you will find all the informations you need to build and program your own. It can be used with the new Flex 6000 Signature rigs.

A brand new controller from Spain!


Latest addition to builders experiences came from Spain! Roberto, EA2CNU, built his brand new controller in few days and gave a different layout to the command controllers. Very nice and effective the big dimpled VFO knob. See more pictures in the builders pages.

A new Arduino controller from John G3WGV



I am happy to suggest you a new Arduino project started by John Linford G3WGV.
It is based on my Arduino libraries but this time you have a dedicated board that can handle two VFO knobs, rotary ancoders a lot of physical buttons.
John used also modified graphics libraries for a better look and feel. Here are some work-in-progress pictures. You can find lot of other informations on John's blog.

New improvements to the standard controller



A new variation from Reinhard, OE3KRB. His new controller is based an a bigger 7inch display and two additional knobs. E10 is dedicated to a new quick tune function: long push puts the transmitter on and control tune and rf power. The same feature is available on E8 encoder: long push in tune puts the transmitter on and control tune and rf power. Now  Reinhard can tune up his Drake L4B very easy and also can control the gridcurrent in a easy way.
