SSTV 27700 USB 15 and 16 Jul 2020
« on: July 16, 2020, 1242 UTC »
Nice to see some more activity on 27700 USB. Timestamps at the bottom of each image. Received on my AFE822x SDR and 11mb dipole up about 40 ft, decoded of course with Black Cat SSTV, the most sensitive SSTV decoder: https://www.blackcatsystems.com/software/sstv.html

It would be really interesting to know the distance the image traveled from.
Listening on an Icom-718 with a 135' OCF dipole or a RSP2.  Grundig G3 and MLA-30 when portable. When QRP I use a Hendricks PFR-3 I built. Coverage is 20,30 and 40 meters.

Someone told me the 1142z image came from 31PAT002 in Portugal.

Really. That seems like unexpected propagation for 27 Mhz

your forgetting most dont follow the 4 watt limit, or whatever limit portugal has on 11 meters, if any.

prolly runnin a kw, i could see that being possible with the right conditions

Yes, check the older logs here on the HFU from last solar maximum, we were routinely getting UK CBers on 11 meters, and the Irish church stations. Looking forward to those DX targets again.

I get that. I have worked plenty of European stations on both 10 and 11 meters when conditions were good, However I have not heard of any stations being received from that distance for quite some time on 27 Mhz. I worked some sporadic E's a few months back, but nothing over 600 miles. There are plenty of 11 meter stations in  all parts of the world running a lot of power and still not making it to the US. Excluding digital modes of course.
