    Back of the garage

    Posted: 04 Dec 2021 05:37 AM PST http://g3xbm-qrp.blogspot.com/2021/12/back-of-garage.html

    This photo was taken many years ago and shows my grandson at the back of
    my garage at the old QTH.

    Original 10m Chirpy transceiver?

    Posted: 04 Dec 2021 05:38 AM PST http://g3xbm-qrp.blogspot.com/2021/12/original-10m-chirpy-transceiver.html

    Looking through my old photos, I came across this one.

    I think it is the original Chirpy 10m transceiver.
    This was later replaced by the Lesser Chirpy as it suffered far less from
    chirp as if you can't guess from the name! 😉

    Amateur radio projects book?

    Posted: 04 Dec 2021 07:44 AM PST http://g3xbm-qrp.blogspot.com/2021/12/amateur-radio-projects-book.html

    Some time ago someone suggested I write a book summarising all my amateur
    radio projects.
    Sorry to disappoint, but this is very unlikely. Writing a book is a lot of work. All my projects are on my website and G3XBM video channel.
    It is nice idea to compile a book, but quite a commitment.
    UPDATE 1500z: I didn't realise quite how many projects I had done (at least 25). Maybe I should do a book. Maybe this should be my winter project? 😉

    15m FT8 RX (Saturday)

    Posted: 04 Dec 2021 09:31 AM PST http://g3xbm-qrp.blogspot.com/2021/12/15m-ft8-rx-saturday.html

    Since about 0908z, I have been on 15m FT8 RX with the Wellgood active loop.
    It is now 0949z and, so far, 130 stations have been spotted with the furthermost E25ETT (9673km) in Thailand.
    UPDATE 1327z: 521 stations spotted with the furthermost ZL4AS (18995km) on
    15m FT8 RX.
    UPDATE 1730z: 612 stations spotted today. QSY soon.

    Sub 9kHz amateur radio

    Posted: 04 Dec 2021 01:44 AM PST http://g3xbm-qrp.blogspot.com/2021/12/sub-9khz-amateur-radio.html

    In 2010 I managed to see DK7FC on 8.970kHz using my earth-electrode antenna
    in the ground. Notice this took hours! Just a faint line. After this,
    several signals across Europe were copied. Note that each marker is 0.1Hz!! Very narrow bandwidths, very good stability and long integration times are essential.

    South Devon in winter

    Many see holiday locations at good times of the year. This was some years
    ago in winter.

    Solar flux is 85 and the SSN 29. A=8 and K=3.

    160m FT8 RX (Friday)

    Posted: 03 Dec 2021 11:58 AM PST http://g3xbm-qrp.blogspot.com/2021/12/160m-ft8-rx-friday.html

    It is now 1958z and I recently QSYed to 160m FT8 RX using the indoor
    Wellgood active loop antenna. So far, 45 stations spotted. with the furthermost RA3GDV (2654km).

    10m FT8 RX (Friday)

    Posted: 03 Dec 2021 09:52 AM PST http://g3xbm-qrp.blogspot.com/2021/12/10m-ft8-rx-friday.html

    At 0923z, my gear was turned on. At 0930z 16 stations spotted so far.
    UPDATE 1750z: 162 stations spotted today.

    OFCOM and protecting radio astronomy

    Posted: 02 Dec 2021 11:08 PM PST http://g3xbm-qrp.blogspot.com/2021/12/ofcom-and-protecting-radio-astronomy.html

    OFCOM is consulting about how best to protect radio astronomy just below
    26GHz. See the OFCOM website for details.

    Best ever QSO?

    Posted: 02 Dec 2021 11:08 PM PST http://g3xbm-qrp.blogspot.com/2021/12/best-ever-qso.html

    My best ever QSO was probably in 2007 when I had a 1W CW QSO on 6m (50MHz)
    with a station in the USA by E layer propagation. It was a very good 6m opening. My antenna was just the V2000 vertical omni. The other station was well equipped, but we had a solid QSO and I have the QSL card to prove it.

    136/137kHz - which modes?

    Posted: 02 Dec 2021 11:06 PM PST http://g3xbm-qrp.blogspot.com/2021/12/136137khz-which-modes.html

    A few days ago I tried spotting on 137kHz WSPR. Nothing was copied.
    I am wondering what modes are used mostly these days on this band?
    Perhaps WSPR is less popular on 137kHz than it once was.

    Shack 1970s

    Posted: 02 Dec 2021 11:05 PM PST http://g3xbm-qrp.blogspot.com/2021/12/shack-1970s.html

    The photo shows my "shack" in the late 1970s. It was a desk in a bedroom.
    Looks like I used a Liner-2 2m SSB rig and an Eddystone EC10 receiver.
    Between the EC10 and Liner-2 is my VXO controlled 10m TX.
