Yes, I saw you in there when I was taking breaks from calling, Don. When I got up this morning, I was surprised to find that I wasn't in the online log as I got an "RR73" from them. That had me concerned that I had worked a very masochistic pirate 🙂. It it looks like they were just late updating the log, however. My Alpha 87 is dead, so I am just running ~600 watts from a KPA500 into my 55ft top-loaded vertical. Clearly Southern California had a big propagation advantage over Alberta to that part of the world last night as you are definitely shooting a bigger flame in their direction than I am.

Hopefully the team will be able to sort out their QRN challenges and band conditions will improve. I am really hoping things improve enough for a CW contact.

I was there too Mike, for way too many hours!  Up here they peaked at -10 and were usually -16 or so.  They never heard my kw+ and full size 4  square.  Same on 80m earlier.   For that area of the world, their transmit signal was pretty weak (that night) and their rx certainly is poor.  I thought conditions were fairly decent.

    C21MM has been in solid for well over 1.5 hours on FT8 tonight and
    it's
    still early. They were loud enough at times (at least on my end)
    for a
    CW QSO, but they didn't decode my signal on FT8 until their signal
    peaked up to R=0, whereas on this end I was decoding solidly down to
    R=-20. Clearly they have some receive challenges. The DHDL antenna
    that
    C21MM plans to use for receive has been employed by AA7JV on some
    of his
    expeditions, so it's got a proven track record. Perhaps there is a
    storm
    that is very close to them causing unusually high QRN.

    I need to go to bed, today is a work day 🙁

    propagation favored EU, but they were active long enough that I
    worked them on both 160 CW and FT8 as well as 22 other band/modes.

    haven't made any topband CW contacts and only 6 with NA presumably
    on FT8.  They claim to have installed an RX antenna, but have high
    noise.  So we shall see, but I'm not holding my breath.  To their
    credit they have worked about the same number of CW and FT8 Qs and
    a few on RTTY, three of them mine.

    These other guys are not so motivated and want to run up their Q
    count by working the most productive bands, or by turning on the
    FT8 robots.
