After the weather zapped the output transistor (a BS150 FET) of my Ultimate3S beacon from QRP-Labs yet again, I was forced to replace the device, again. It is not a difficult job at all, just a little chore. This time I decided to make it easier on myself. Instead of replacing the transistor by soldering…

Beaconing Five Modes in Twenty Minutes
While WSPR’ing across multiple bands (“band hopping”) has been done before, I thought it might be interesting to do five different modes on the same band. It was easier done than said! I was sitting with a customer’s QRP-Labs Ultimate3S beacon on my bench, all built up and ready to test. It was a single…
No Sound from my SDR
And in other news, I’m trying to play with this cute little SDR receiver (the cuteness which I am sharing with you in another post), but I’m having mega problems. Don’t get me wrong: The issue is not SDR or this cute little Rx. I own and operate a Flex-1500 which has quietly become my…

QRSS on 30m with Arduino
QRSS is not something I knew anything about, until I stumbled across a useful use for my Arduino: A small daughter board (called a shield) with a few components to turn it into a QRSS transmitter. I admit I am lazy and morse code is way out of my reach – know the joke? did…

Working PSK31 with a X1M and Digimaster Pro3
Interfacing a Xiegu X1M 5 watt QRP HF transceiver to a G4ZLP Digimaster Pro3 to go digital and portable on the HF bands, by Leon Uys ZR6LU. I recently obtained a Xiego X1M HF radio from OM Rory in Port Elizabeth. Nice package and works SSB out of the box. I took it with me…
