Improved HF conditions return

After the solar storm of last weekend, settled conditions have finally returned to the HF bands.

It is typical to see the Mid-West ‘wall’ in place with all signals to the West (except the exceptional) not making the trip to Europe. Today the West coast of the USA was coming through very well on 20m.

630m WSPR activity is increasing, and Trans Atlantic propagation will probably return this month – an event we are watching for on a daily basis.

Although Sporadic-E is still evident from time to time, over the last week the openings have been brief and it’s clear the season is ending. The bands above 17m have been mostly quiet – as without Sporadic-E enhancement the low sunspot numbers do not support propagation on the higher bands at this latitude.

  1. Thanks for hearing my 630 meter WSPR las night. I am Jack, AA3GZ, 151 Short Road Doylestown PA 18901, FN20KH. My 630 meter rig is a 100 watt FET amplifier driven by the one milliwatt drv outpot of my Kenwood TS-590SG transceiver. The antenna is a 20 meter high top-loaded vertical with two 1/4 wave ground radials producing 5 watts ER
    P. I operate all modes from 630 meters to 70 cm. On HF I output 600 watts from an Ameritron ALS-600 solid state amplifier to a terminated rhombic antenna 20 meters high and 60 meters long on each of 4 legs; gain is 9 dbi on 40, 14 dBi on 20, and 16 dBi on higher frequencies. I can direct it toward Europe or ZL/VK. The F/B is 30 dB so it is very quiet on receive. I have an inverted V for 160 and other antennas for different directions, and a 5 element Yagi for 6 meters.age 91.5 licensed for 75 years. Retired aerospace communications engineer

    1. Hello Jack,

      Thank you for your comment, and providing information about your installation. It was good to receive you on what was a great night for 630m propagation. The Rhombic is an excellent antenna, which I would use myself if I had the real estate. At this time, I am concentrating on improving reception on all bands from 2200-10m by experimenting with different Wellbrook loop sizes and orientations and, most importantly, isolating and eliminating noise sources. WSPR is an excellent mode for determining antenna performance and I hope to receive your signal again over the forthcoming months.

      Regards,
      Geoff
