Remote ATU (variable coil) with integrated PA control

Wide range precise remote ATU, based on old Soviet military station P-140 variable coil. This ATU targeted for SDR integration and uses cross-platform application (called ATU Connect) for control. Current version v.0.3 release.

T-network Remote ATU with ESDR TCI integration.

T-match one is the design "repeating" the P-140 one in fixed coils, capacitors and relays. Universal controller/SW/Protocols/Integration design can also operate with L-network, based on N7DDC ATU. Extended tuning algorithms. Designed for DXpeditioners by DXpeditioner, less wind resistance and minimum weight/size in mind. Active project. Current version v.0.2 release.

OClog (in progress)

Lghtweight, cross-platform, open sourse, based on TCI protocol HAM radio log witn MQTT capability for SunSDR tranceivers.
Current version in in full re-design mode, porting it to Qt6. Estimated completion is end of April 2021.

Flatpack2 rectifier control

This project was originally designed to cover power supply for MOSFET-based Power Amplifierss. However, over years it was found usefull by my friends for other applications..

TCI-MQTT Gateway

JS-based library. Qt6 is out now ... however ... there are few issues, if you want to develop Qt6 QML own application with TCI. First issue is that there is still no Websockets in Qt6 (which is pre-requisite for TCI). And second issue that there is no QML integration of TCI. Yes, there is a workaround - you can use Websockets of Qt5 and you can develop your own integration - this is time-costly and a bit fluffy way :). We have another. Together with coleague of mine we have developed TCI-MQTT Gateway, which simply connects to ESDR via TCI and translates all TCI traffic into MQTT JSON topics. Then you can easily operati with those topics in QML with MQTT. Very simple, lightweight, does the job and opensourse. Can be found here, on Github.. Please note that it is in WIP mode now, but we are working on it :)
