I just had a quick #CW qso with Feroe Islands on 17m, using my 20m dipole and my manual tuner. I got a nice 559 report using only 10 watts, so it seems to be working somehow. SWR at the tuner reads 1.2. How would you estimate the radiation efficiency of such a setup ? Modelling in NEC ? #hamradio #antenna
I love my Alinco DX70, but the CW filter sucks a lot 🙂 40m is crowded now, and I can't isolate anyone, even with delta-IF, the filter is too large 😕 #cw
Do you know if a system exists in receivers, that would 'enhance' CW reception : once properly tuned and with a very narrow filter, the receiver would detect peaks in signal level, and play a synthetised dit or dah at normalised level with zero noise around it, instead of playing the original wavefrom plus the noise. I hope this makes sense :-) #cw
I have just received this beautiful ham prefixes map from Aliy UA6YW :-) I love the design and colors. Aliy included a little extra CQ zone map as a gift. Love the nice Russian stamps, too. It took ages to make it through the mail, but in the end I really recommand Aliy's map store at : www.kuisokov.ru #hamradio #map

A way to hook up a morse key to the USB port of a computer or a phone with an old computer mouse..
Looks interesting. I will probably try that. Now how to transport morse from one computer to another via network? Not sound samples for sure. MIDI? Or are there better ways?
Hello ! I am very pleased to join . I am a new ham since march 2020, but a long time radio enthusiast and listener. I am mainly motivated by learning new things. I like building #antennas and am trying to understand the underlying #antennatheory. I love long #dx QSOs with people from other cultures. I am also a long time #linux user. Other than that, I am a painter, as @patricepoly .
I hope to talk to you on air soon !
