New FT8 QSOs

Well, after a bit of a strop yesterday about FT8 activity being disrupted by a new version being released by Joe Taylor and friends, I have now settled down!

I managed to install the new WSJT-X on both the laptop and Raspberry Pi 3B+ with no difficulty (other than some strange message about 'user activity', which seems to have no relevance to my operating).

As generally agreed, most people clearly haven't heard of the new release, because about 4/5 or more of FT8 signals are still old-school, and not being decoded either way.

Still, the new mode is obviously going - eventually - to become the norm, so I am sticking with it until more people make the switch.

In the meantime, I was very happy to get a call from an incredibly strong VK7BBB (sadly, another operator with no station information on QRZ.com) on 17m this morning on the new version FT8:

I'm curious about the more sensitive WSPR decoding. Will it decode more? You're the WSPR receive expert....;-). 73, Bas

Hah! I'm no expert in anything! I think modes other than FT8 and MSK are "unchanged", according to the website. I've started trying to use a recorded reference spectrum, but it will take some time to work out if that makes a difference.

...but looking at the documentation,. there is a claim the WSPR sensitivity is "improved". Confused?

You should indeed make a recording and compare old versions with this new one. I most of the time WSPR with an old version of JTDX since it is featuring sliders for both receive as for transmit. It would be interesting. If I had some spare time...hope you can work it out. 73, Bas
