Recently my Yaesu FT857 became deaf. It turned out that the plastic enclosure of the FT857 filters over time consented to moisture which ruined the filters. In this post, I’ll show you how I replaced the filters and brought the radio back to life.
The community of Flex-Radio enthusiasts who select the DJ Console as their main user interface is steadily growing. Community members are sharing pictures to make it even better. After several labeling solutions, a recent discussion on the PowerSDR-UI Yahoogroup ended up in a haptic improvement for the DJ Console’s tuning wheels.
It finally happened… After a decade of reliable service, my Alpha91b amplifier broke. Most likely on its way to Spain one of the tubes broke. During the commissioning at ED1R, fire & smoke shot out of a chimney. The first shock was big, but a few measurements confirmed that just the tubes were broken. In this blog post, I will share the knowledge I gained during debugging, commissioning, and breathing new life into the amplifier.
In this article, we will investigate how various Contest programs (Win-Test, N1MM, and CW-Skimmer) communicate with the FT1000MP shortwave transceiver over the serial port. We will see what happens when multiple programs try to talk to the transceiver at the same time, what problems appear and how we can successfully monitor and debug them.
