Sunspots and 10m - Tues Nov 24th 2015

Sunspot number is 77 today (K=0) and solar flux is good at 119.  Sadly the 10m propagation forecast is "poor" today. It will be interesting to see how 10m WSPR is today.

UPDATE 1017z:  From Australia VK2KRR (16789km) has already spotted me 4 times today on 10m WSPR!  Ignore that "poor" forecast, HI. I find it quite amazing how a "poor" 10m forecast is given and yet my little W5OLF 10m 500mW WSPR beacon is spotted right around the planet. 6m and 10m are "magic bands" as sometimes they spring real surprises. Wolf's 10m beacon does not need a PC and would fit in a very box. It is great. I have had mine a year and I have had such fun with it. It never fails to amaze me how something so small on the desk is regularly spotted at great distances, even with a very small, modest, wire antenna. The antenna is hardly visible. Spots from the USA are almost daily and it has been spotted in Australia on 8 different days (I think) this autumn. -18dB S/N (twice today from Australia) suggests even 40mW might have been enough! Quite amazing.

UPDATE 1052z:  No further 10m spots and all quiet so far on 6m WSPR.

Hi Roger
Over the last few days I've been trying WSPR on 10m with just 10mW. On Sunday morning VK2KRR spotted me at -26dB. Amazing isn't it?

P.s. I hope your 2m big wheel has stayed up OK?

Excellent David. Yes thanks the 2m big wheel seems fine.
