    160m FT8 RX with the active loop

    Posted: 04 Sep 2021 03:39 PM PDT http://g3xbm-qrp.blogspot.com/2021/09/160m-ft8-rx-with-active-loop.html


    In the end I gave up on 630m (472kHz) WSPR RX and went instead to 160m FT8
    RX with the indoor Wellgood active loop. So far this evening, 3 spots
    including an EA and DO.
    UPDATE 2136z: 9 stations spotted. mostly in northern Europe. QRT.

    As last night, I am on 472kHz WSPR RX with the Wellgood active loop with
    the 1m diameter loop indoors on the shack window. It is now 1857z and, so
    far, no spots.
    UPDATE 2136z: No spots this evening. Very disappointing. I may QSY.

    10m WSPR QRP TX (500mW)

    Posted: 04 Sep 2021 11:51 AM PDT http://g3xbm-qrp.blogspot.com/2021/09/10m-wspr-qrp-tx-500mw.html


    At 1424z, I decided to go on 10m WSPR TX with 500mW from my 10m WSPR beacon
    by W5OLF. This is about the size of a pack of cards and 100% TX, although
    the TX frequency is randomised on each slot.
    UPDATE 1437z: So far, just local spots by G4KPX (14km). From Richard's
    spots, it looks like the crystal is still settling.
    UPDATE 1500z: Still just G4KPX spotting me, although my drift has stopped.
    It looks like things have stabilised, as usual. This normally takes about
    20 minutes.
    UPDATE 1510z: OE3XOE (1233km) now spotting me.
    UPDATE 1635z: No further stations have spotted me.
    UPDATE 1845z: QRT.

    10m FT8

    Posted: 04 Sep 2021 07:19 AM PDT http://g3xbm-qrp.blogspot.com/2021/09/10m-ft8-rx.html


    In the end I decided to QSY to 10m FT8 RX.
    At 1259z, 5 stations were spotted so far on 10m FT8 RX. I may try 10m FT8
    TX with 2.5W shortly. My antenna is a Par end fed dipole antenna at about
    3m above ground.
    UPDATE 1304z: TX switched on. 1 spot of me on TX by G6TUS (18km).
    UPDATE 1318z: 6 stations spotted on RX and 6 stations have spotted me on
    TX with the furthermost IS0AWZ (1598km).
    UPDATE 1359z: So far this afternoon, I have been spotted by 8 stations on
    TX (as the map shows) and I have spotted 15 stations on RX.

    30m FT8 RX with the indoor active loop

    Posted: 04 Sep 2021 05:35 AM PDT http://g3xbm-qrp.blogspot.com/2021/09/30m-ft8-rx-with-indoor-active-loop.html


    I am trying FT8 on 30m with the Wellgood active loop. I think there is an internet connectivity issue as I am getting local spots, but these are not appearing on PSKreporter. I tried a reboot without success.
    UPDATE 1023z: Working now. 10 EU stations spotted so far.
    UPDATE 1206z: 17 stations spotted with the furthermost UA3DPM (2893km).
    UPDATE 1233z: 35 stations spotted on RX with the furthermost being JW4PUA (2952km). Soon be time to QSY, but unsure where to!

    40m FT8 RX with the active loop antenna

    Posted: 04 Sep 2021 02:27 AM PDT http://g3xbm-qrp.blogspot.com/2021/09/40m-ft8-rx-with-active-loop-antenna.html


    At the moment, I am on 40m FT8 RX using the Wellgood active loop stuck to
    the shack window. Noise level on the FT817ND is about S4. So far, 8 unique stations spotted (at 0800z) with the furthermost TF5B (1813km) in northern Iceland.
    Although it will probably work at higher frequencies, I doubt it will
    seriously be used at HF.
    See https://www.george-smart.co.uk/projects/wellgood_loop/ .
    UPDATE 0858z: 32 stations spotted. The map shows the stations spotted.
    UPDATE 0927z: 45 stations spotted.

    472kHz WSPR RX with the Wellgood active RX loop

    Posted: 04 Sep 2021 01:15 AM PDT http://g3xbm-qrp.blogspot.com/2021/09/472khz-wspr-rx-with-wellgood-active-rx.html


    Last evening I was active on 472kHz WSPR RX using the Wellgood active loop
    RX antenna. This is very similar to the Wellbrook active loop. I swapped my
    X80 HF vertical for one.
    In all, just 1 station was spotted - DC0DX (467km) - with the 1m diameter
    wire stuck to the window indoors. Noise levels are low. This is my first
    outing on 472kHz RX for some while.
    I may try again this evening.
    See https://www.george-smart.co.uk/projects/wellgood_loop/ . George
    designed this as he was trying to mend his Wellbrook loop.
