    That free PDF book - this week?

    Posted: 05 Jun 2022 03:03 AM PDT http://g3xbm-qrp.blogspot.com/2022/06/that-free-pdf-book-this-week.html


    Barring last minute issues, my personal aim is to complete my free PDF Scrapbook this week. The trouble is, I still think of things to add! If I think of any more, they will have to wait for a future update.
    My hope is that this collection will lead to your own ideas and be a springboard. At least producing a free PDF book allows you to make updates whenever you want and if the grammar and spelling are not perfect, too bad. After all, good engineers are usually poor at grammar and spelling. This is
    in my opinion from work days. I guess it is something to do with how our
    brains work. Tell me the last time you can remember a good engineer who was also good at poetry? I have known at least one, but these are the
    exceptions.

    10m QRP WSPR (Sunday)

    Posted: 05 Jun 2022 04:30 AM PDT http://g3xbm-qrp.blogspot.com/2022/06/10m-qrp-wspr-sunday.html


    As the antenna is available, I am again on 10m WSPR TX with 500mW to the
    W5OLF beacon. So far, spots from OE3XOE (1233km). As this is early, this is promising.
    UPDATE 1131z: 12 stations have already spotted me today.

    8m experiment (Sunday)

    Posted: 05 Jun 2022 04:29 AM PDT http://g3xbm-qrp.blogspot.com/2022/06/8m-experiment-sunday.html


    My QRP FT8 8m station was turned on a 0844z on 40.680 MHz USB dial (first)
    with an audio offset of about 2 kHz. Let's hope for some Es.
    UPDATE 0856z: There is some Es to central Europe on 10m - hopeful sign.
    UPDATE 1009z: Spotted in the Algarve, Portugal again by SWL HC02
    (1808km). Gear now off whilst it cools.
    UPDATE 1129z: 2 stations have spotted me now, despite my QRP. The
    latest is 9A2TN (1481km).

    Oscar 100 narrowband transponder

    Posted: 05 Jun 2022 01:52 AM PDT http://g3xbm-qrp.blogspot.com/2022/06/oscar-100-narrowband-transponder.html



    As regular readers know, every few weeks I take a look at activity levels
    on the narrow-band transponder of this geosynchronous satellite. Activity levels remain low considering my last peek was on a European weekend
    morning. when I would have expected activity to be quite high.

    ICOM SHF transceiver?

    Posted: 04 Jun 2022 01:09 AM PDT http://g3xbm-qrp.blogspot.com/2022/06/icom-shf-transceiver.html


    The EI7GL blog has quite a bit about this.
    Sadly, I cannot see this ever coming to market. Surely the big
    manufacturers are only really interested in making money. I can only see
    this selling in low numbers, hardly covering development costs.
    See https://ei7gl.blogspot.com/2022/04/icom-shf-microwave-project-for-24-ghz.html .
