481THz test

Posted: 12 Oct 2021 11:08 PM PDT http://g3xbm-qrp.blogspot.com/2021/10/481thz-test.html


OK, these are tiny steps. Yesterday I did a test reflecting my optical
beacon from the kitchen, off the museum roof, to the RX in the lounge. I
would guess the total path was only about 0.2km. The reflected signal was extremely strong, so I might try receiving the reflected signal at my son's house further away.
Unlike many years ago I am extremely giddy now. At one point the TX crashed
to the floor. Luckily, nothing was broken.
I am just too wobbly for field work, but I want to do what I can. Receiving 10wpm CW at my son's house would be a great achievement for me nowadays.

10m WISPY

Posted: 12 Oct 2021 11:06 PM PDT http://g3xbm-qrp.blogspot.com/2021/10/10m-wispy.html


Although both the TX and RX were built, I never got around to boxing and testing the full transceiver version. It should work, but I have not tried
it. You may want to use it for your own ideas.

I have been surprised by the WSPR activity still on 10m. Back in the Es
season my beacon was widely spotted most days. The same basic idea would
also work on FT8. It depends on finding suitable, low cost, crystals.
Please note there was an error on the schematic: the main winding on the inductor in the oscillator collector should have 22 turns and not 9 turns.
