472kHz WSPR QRP TX

Posted: 21 Sep 2021 07:25 AM PDT http://g3xbm-qrp.blogspot.com/2021/09/472khz-wspr-qrp-tx.html


I really should try to find the fault in my 472kHz transverter.
At first, I thought it was my earth-electrode antenna, so I completely
replaced the wire. The output FET was replaced.
If my brain was less foggy I am sure I could get to the bottom of it and
find what is wrong. With 10mW ERP (measured) it was regularly making it to Norway.
There are a lot of people monitoring, but few on TX.

A reminder that a lot of my past projects are on my website.
On my video channel you can find videos about my projects.
I hope you can be inspired by these sources. Nothing would please me more
than if these were a springboard for your own projects. Probably all my projects can be improved, so don't be afraid to experiment.

10m FT8 QRP (Tuesday)

Posted: 21 Sep 2021 02:15 PM PDT http://g3xbm-qrp.blogspot.com/2021/09/10m-ft8-qrp-tuesday_21.html


Following my usual pattern, I went on 10m FT8 TX with 2.5W for a few
minutes and then RX only. No spots given or received and no QSOs.
UPDATE 0902z: 2 spots on RX with furthermost F5RD (681km).
UPDATE 1400z: 8 stations spotted on RX with the furthermost LZ1AG (2145km). Probably a brief bit of Es?
UPDATE 1603z: 36 stations spotted on RX with the furthermost A65BR (5455km)
in the UAE.
UPDATE 1803z: 78 stations spotted with the furthermost ZS1F (9745km).
UPDATE 2112z: 112 stations spotted on 10m FT8 RX today. QRT soon.
