sweet I just received some APRS frames from the ISS with a hacky coathanger wire dipole :-)

I just had a quick 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 ?

Did you know about Proppy ? : soundbytes.asia/proppy/
It is a nice online prediction suite. I find it a great alternative to voacap

Received today : " you are 5 by 9, I didn't understand anything of what you said" :-)

wow 20m is really dead ! You would wonder if you really have an antenna πŸ™‚

I love my Alinco DX70, but the CW filter sucks a lot πŸ™‚ 40m is crowded now, and I can't isolate anyone, even with delta-IF, the filter is too large πŸ˜•

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 :-)

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

Hearing UK station on 14178 >_> faint but 5

20m is really rotten tonight for me ! I wish I had 40m ready. QRT and comics in bed, I think

Any of you also see these nasty frames on 14.050 ? it spreads on 20 khz. I see some on the Twente sdr, but not all. I am wondering what these are.

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 and am trying to understand the underlying . I love long QSOs with people from other cultures. I am also a long time user. Other than that, I am a painter, as @patricepoly .
I hope to talk to you on air soon !
