50 MHz Sporadic-E propagation using JT9-1 mode

Yesterday, Wednesday 12th June 2013, was my first attempt to use the new JT9-1 data mode by K1JT on the 50 MHz band taking advantage of current Sporadic-E openings throughout Europe. This is an experimental mode and is available as part of the WSJT-X software.

I was using my Kenwood TS-2000 transceiver, 25W into a new 50 MHz HALO loop mounted at only 2m AGL and was transmitting and receiving on the 50.293 MHz frequency where 6 metre activity is found.

I saw on my display several traces and decoded signals straight away, this was to be the start of several QSO’s I made, shown on the map below.

My very first contact was with OZ1PIF in JO65 square with an estimated MUF of 71.4 MHz according to LiveMUF data as the distance away from me is only 949km. He had a very strong signal +14 whereas I was only -7. At the end of the QSO I found he was using 250 W into a 4 element beam, compared to my 25 W into a Halo. Great fun was had working this mode and several more followed, see screen captures below.

I’m definitely going to use this mode and software again, it was very interesting and I even saw stations in Europe working VE (Canada) which I could not hear.
