Just downloaded the sources from v1.6.1 and compiled this new experimental version.
Works excelent here with my Ft-817ND interfaced with mircoHAM USBIII at Ubuntu Vivid on a 64Bit machine. I was able to change for ham radio purposes completely to Linux now.
Thank you very much Joe and all the other developers who made this possible.

Having always troubles with long wires, I decided to test a magnetic loop. Therefor I soldered a square 128cmx128cm, with 12mm copper pipes, organized a variable capacitor via ebay and but this construction on the kitchen table.
It is amazing - I got a spot from WB2EEE over a distance of > 6000 km, -28 dB, for my 10 watts, inside the building at the 1st floor.
Test showed me, that I can use it on 30m and 20m too. Let's see what will happen later this night on 40m. Tomorrow at daytime I will test on 30m and 20m with the antenna at the balcony.


My interest is mainly to observe propagation over the bands for my own education.
Until now I did use mainly FAROS for this purpose, because it gave me a nice graphical overview. The disadvantage was that the beacons from the International beacon Project are limited in numbers and only from 20m to 10m band.

So I was really missing 40m and 30m.

When I heard that WSPR 3 has a "frequency hopping mode", it was time to google for the program and try it.

Today I mounted my new T2FD antenna, Diamond WD330J, under roof. The width is 25 m and therefore I had to fold the arms in 90 degree horizotal. First tests showed SWR under 2 on all bands 40 - 6m.
80m SWR is horrible, even the FT-950 stopps tuning immediatly, but this could be a reaction of the nearby 1/2-G5RV I didn't remove at this time.

Would be nice to get information from other stations using T2FD antennas.

Yesterday I took the time to install on a virtual machine with ubuntu 12.04 the WSPR source.
Just to try if I'm able to do the job right.

An article from blog.marxy.org helped me to get basic information. In the chat section here someone mentioned it this week.
