    Simple radio project

    Posted: 10 Oct 2021 08:13 AM PDT http://g3xbm-qrp.blogspot.com/2021/10/simple-radio-project.html


    My original post was banned by the censors as it violated blogger
    guidelines, probably as the algorithm saw certain words. Talk about nanny state!! In the gaps, insert letters!
    With my own ch***n, I totally failed to get them interested in amateur
    radio! In 2 weeks time my gran###n is here. His d*d has asked me to work
    with him on a radio project.
    I have ordered a TA-7642 (ZN414) TRF chip from GQRP club sales, but realise
    I shall also need a small slab ferrite rod, a high impedance crystal
    earpiece and a 1.5V battery holder. My building skills are really poor
    compared with before my stroke: what would have been really easy is now
    hard.
    If I cannot find these parts, I shall have to build an LED signaller
    instead.
    It would be good to see another novice operator. Oh look, there's another flying pig. 😉

    10m FT8 RX

    Posted: 10 Oct 2021 01:02 PM PDT http://g3xbm-qrp.blogspot.com/2021/10/10m-ft8-rx_10.html


    At about 1350z, I QSYed to 10m FT8 RX as 6m seemed so dire. So far, 7
    stations have been spotted with the furthermost CO8RH (7231km) in Cuba.
    10m seems to be reliably opening to the USA and Canada again via F2.
    UPDATE 1526z: So far this afternoon, 83 stations have been spotted on 10m
    FT8 RX, mostly in the USA.
    UPDATE 2003z: 368 stations spotted this afternoon on 10m FT8 RX. 10m F2 propagation is definitely back in a big way! QRT.

    6m FT8 QRP (Sunday)

    Posted: 10 Oct 2021 06:38 AM PDT http://g3xbm-qrp.blogspot.com/2021/10/6m-ft8-qrp-sunday.html


    Just before 1100z, I turned on 6m FT8. After a short time (minutes) on 2.5W
    TX, I am RX only using the V2000 vertical omni antenna. So far, no spots on
    RX, but spotted by G0PQO (50km) on TX.
    It would be a pleasant surprise to spot anybody on 6m today. Although Es
    does occur, it is far less common at this time of year.
    UPDATE 1335z: Just 2 Gs spotted today on 6m FT8 RX. As 6m seems so poor, I shall probably QSY, probably to 10m FT8 RX.

    2m FT8 (Sunday)

    Posted: 10 Oct 2021 03:39 AM PDT http://g3xbm-qrp.blogspot.com/2021/10/2m-ft8-sunday.html


    After a brief few minutes with 2.5W TX to the big-wheel (7 stations spotted
    me) I am RX only now. On RX 14 stations spotted in 5 countries with the furthermost MI0IHH (473km). Judging by the strength, I think this one in N.Ireland was aircraft scatter.
    UPDATE 1038z: 28 stations in 7 countries spotted on 2m FT8 RX today. It
    never fails.

    10m WSPR QRP (Sunday)

    Posted: 10 Oct 2021 03:41 AM PDT http://g3xbm-qrp.blogspot.com/2021/10/10m-wspr-qrp-sunday.html


    At about 0920z, my 500mW W5OLF 10m WSPR beacon was turned on. So far, no
    spots.
    UPDATE 1040z: So far spots from 3 unique stations with the furthermost by TA4/G8CSU (3010km).
