10m JT65

Before breakfast I turned the PC and rig on and checked internet time sync. As yet, no spots given or received. South America (if at all) usually gets through late afternoon. There are quite a few monitors in Europe, but they have not copied me yet. I am convinced that JT65 is a very effective 10m mode as the solar cycle recedes and conditions get worse. I remain convinced there is life on 10m long after most people abandon it. My advice? Run 10m JT65 or WSPR in the background and be surprised. On most recent days, 10m has opened to somewhere briefly.

UPDATE 1054z:  Still no 10m JT65 spots as yet.

UPDATE 1625z:  Only UK spots today on 10m JT65 with best DX G0JEI (141km) on RX. So, no great DX today!

Sunspots and 10m - Tuesday October 25th 2016

Solar flux is 75 today and the sunspot number 13. K=4. On the face of it, we should not expect great 10m conditions today, but we may be surprised on JT65 and WSPR!

Back on 10m JT65

I returned to 10m JT65 quite late this morning, as we were late getting up. Normally, I put things on before breakfast. So far just UA3GT (2635km) spotted by F2.

UPDATE 1202z:   As well as spots of my signal from across Eastern Europe I have spotted stations widely in Europe and Israel. Best on 10m JT65 RX is 4X1QQ (3551km).

UPDATE 2026z:  Just a single South American spotted on 10m JT65 today, after a more promising start.

UPDATE 2050z: Now QRT. Back in the morning.

Sunspots and 10m - Monday October 24th 2016

Solar flux is 77 today and the sunspot number is 14. K=3.

QRT until the morning

After a pretty good day on 10m JT65, I have now gone QRT and will be back on the band in the morning. I did not expect to be copied in Australia this autumn or ever again on 10m. With declining solar conditions, this was a total surprise.

SAQ (VLF CW) Off Air

Apparently, SAQ (17.2kHz) had a fire caused by arcing and is off the air presently. I have no idea if they will be back in time for their usual transmission around Christmas. I am a proud owner of one of their QSL cards from several years ago.

Maths - NOT amateur radio

Our elder granddaughter (5) doing maths with granny at the kitchen table. She is very keen to learn - our granddaughter that is. I think granny has done enough maths!

10m JT65

This morning I went straight to 10m JT65. I switched on about 20 minutes ago, which is later than usual. As normal. I checked the PC was synced to internet time. Before I set things going I could hear a couple of stations.

UPDATE 1012z: Several stations in Russia, Finland and South Africa spotted and my own QRP 10m JT65 spotted by several Russians. F2 I assume. At the moment, things look quite promising on 10m JT65.

UPDATE 1130z:  My 2W 10m JT65 was spotted by VK6KXW (14542km) in Western  Australia and ZS6ZP (9121km) in South Africa as well as widely in Europe. 10m JT65 is good today.

UPDATE 1954z:  Lots of spots of South Americans but no spots of my own QRP 10m JT65 signal from stations in that continent. Still waiting for a decent F2 opening on 10m JT65 to the USA this autumn.
