    Lightning risks

    Posted: 24 Apr 2022 09:46 AM PDT http://g3xbm-qrp.blogspot.com/2022/04/lightning-risks.html


    The chances (in the UK) of being hit by a direct lightning strike are (thankfully) low, but not nil. Many years ago a work colleague in a very ordinary house was struck and he had a lot of damage.
    More common issues are power surges of the mains supply when lightning and thunder are nearby.
    Perhaps I am paranoid, but if there is a threat of lightning nearby I
    unplug PSUs from their sockets and disconnect all antennas. If a power
    surge is around my gear is not going to experience it!
    Unless you have a very good grounding systems, it is very unlikely your
    gear will survive a direct hit.
    Now, I am no expert on lightning protection, so please make your own
    judgements on this by reading expert opinion. DO NOT rely on me!!

    4 element Yagi for 70cms

    Posted: 23 Apr 2022 01:44 PM PDT http://g3xbm-qrp.blogspot.com/2022/04/4-element-yagi-for-70cms.html


    Some years ago I was looking for an antenna for a 70cm contest to take out portable. It performed well with QRP SSB. Like similar antennas of mine, it
    was fabricated from an old metal coat hanger. It was a good match and used
    with my FT817. I still have this antenna in the back of the garage.

    10m QRP WSPR TX (Saturday)

    Posted: 23 Apr 2022 02:03 PM PDT http://g3xbm-qrp.blogspot.com/2022/04/10m-qrp-wspr-tx-saturday_23.html


    As my 10m antenna is available, I am on 10m WSPR TX with 500mW from my
    W5OLF beacon. So far, just spots from local G4KPX (14km).
    UPDATE 1630z: 6 unique stations in 3 continents have spotted me today on
    10m WSPR.
    UPDATE 2100z: QRT.

    8m experiments today (Saturday)

    Posted: 23 Apr 2022 02:06 PM PDT http://g3xbm-qrp.blogspot.com/2022/04/8m-experiments-today-saturday.html


    My experiments on 8m carry on today. Yesterday EI9KP (649km) spotted me
    again. Whilst at home I shall go on FT8 TX but when out I shall be
    monitoring 40.680 MHz USB dial FT8 RX.

    UPDATE 0925z: My TX was turned on at 0850z. Now RX only. No spots given
    or received.

    UPDATE 1625z: As I was out most of the day I was mostly on 8m FT8 RX. 3 stations spotted.
    UPDATE 2103z: QRT. No further spots today.
