    If you're going to operate HF before heading back to work in earnest, today might be the day to do it!

    Solar Flux Index (SFI): 218

    A-Index: 6 (low)

    K-Index: 1 (very low)

    These might be the best numbers of the winter. Let's hope they hold through the day.

    Good Luck, and see you on 10 or 15M today.

    I expected 10m to be a lot better today, but so far, not really.

    I'm handing out points in the RTTY RoundUp.

    Very cool indeed. I am hearing signals (faint CW) on 10m, using my homebrew 3-transistor regenerative receiver.

    For the whole of the previous 7 months since i build the set, I've never heard anything at all on 10m. Not a sausage.

    Now let's see if I can copy some of those QSOs!!!

    Folks, the 10m station I'm hearing on my primitive equipment is N1CC whose QTH is Frankston, TX. Very cool.

    He is calling CQ, strong signal (RST 579 here), medium speed CW as of 1713 UTC with no takers so far. Frequency approximately 28028 (remember that I'm technologically in the 1960s with homebrew gear, so don't expect a precise frequency from me!).

    From time to time it gets much fainter, then comes back strong. Doesn't sound like QSB, I think he is swinging his beam.

    Rest of the band: up, I can hear some very faint SSB but cannot copy.

    Lovely to get some use out of that little 10m coil I wound last summer....

    Edited to add further monitoring as of 1730 UTC:
    --Medium-speed CW QSO on about 28250.
    --Slow CW QSO on about 28290.
    (Haven't caught any of the callsigns yet.)

    There are heavy, whooshing waves of QRN swamping the signals periodically.

    At 1816 UTC I can hear the K5TLL/B beacon, QTH Hattiesburg, MS, on 28298 with heavy QRN but legible. We seem to have an opening south=>north on the band given what I'm hearing.

    combine that with a foot of snow so far and sub zero temps on there way and you may be right.

    Eat your hearts out....

    Oyez, oyez! Ye denizens of the thousand-dollar rigs, eat your hearts out!

    I have this day heard CW and SSB signals on 10m, and in some quantity. (Listed in my earlier posts, and several more since.)

    Any DX? Well, one of them seemed to be a QSO on 28002 between an "I" and a "K" but I cannot confirm that since I didn't get the entire callsigns. It was at around 1900UTC.

    All of this with a set that relies upon a single MPF-104 FET regenerative detector (at center in the photo below) followed by a two-transistor audio stage.

    Admittedly the conditions today were very good and it's the first time I've ever heard anything on 10m....

    Also admittedly, tuning the set on 10m is a challenge. All sorts of adjustments, including the addition of a series capacitor on the antenna input and messing around with some other component values. Plus, because of the considerable width of the 10m band, tuning across the band is a two-handed affair, one of them on the big tuning dial and the other on the fine regeneration control.

    Just worked W0LS, W7NGA and WA6HDY... all on 21.440 MHz AM. Sigs were weak to moderate.

    I was fully modulating a 175-Watt carrier. Lots of fun. :)

    Despite the SFI being 218 the bands sounded no different to when it was 120. Nobody on PSK is hearing or working any DX, all I'm seeing are the same stations I always see. So it seems the SFI means nothing these days because the upper atmosphere isn't being ionised

    Yesterday wasn't so special in my book either.

    Eh... a bust in my book.

    I was hoping.
