    Par EF-10/20/40

    Last year, this developed a fault.
    I strung an end-fed wire using the Par transformer out of the shack window.
    The VSWR looked low, so I assume this Par transformer is fine. At some
    point I shall re-erect this tri-band antenna, but with new coax. Either
    there was moisture in the coax or the plug had failed.
    In the past I have been spotted all over the planet with this antenna and
    500mW WSPR on 10m. It is good for 35W, although my absolute maximum is 10W
    and often much lower. With WSPR and FT8 it is far lower.

    6m FT8 RX (Tuesday)

    Posted: 15 Jun 2021 05:43 AM PDT http://g3xbm-qrp.blogspot.com/2021/06/6m-ft8-rx-tuesday.html


    It is now 0759z. A few minutes ago I turned on 6m FT8 RX using the FT817ND
    and the V2000 vertical omni. So far just G4IFX calling CQ DX, no doubt
    hoping for the Far East.
    Just now I realised I was looking at the 12 hour view on PSKreporter maps.
    I am now looking just at today. So far just 2 Gs spotted (0807z).
    UPDATE 1112z: 18 stations spotted. No Es evident here.
    UPDATE 1237z: 26 stations spotted including the furthermost HI3T (7001km)
    in the Caribbean. With no Es evident here, I am more convinced than ever
    that some of these long distance paths are not Es, but some other E layer propagation. I am sure with a better antenna, higher up, I would copy far
    more, especially as the V2000 being faulty.

    6m FT8 RX yesterday (Monday)

    Although fewer stations were spotted, there was DX from the Caribbean
    copied on the FT817ND and the V2000 omni antenna. In all, 293 stations
    spotted. Better equipped stations were working plenty across the Atlantic.

    Solar flux is 77 and the SSN 11. A=4 and K=2.

    PAR = Phase Angle Regulating ? Please advise. <https://www.pes-psrc.org/kb/published/reports/Protection_of_PAR_Transfor mers_Report.pdf>
