Sunspots and 10m - Thursday April 2nd 2015

Sunspot number is 69 today (K=3 so a bit more disturbed than yesterday) and 10m propagation yet again "fair".

So far today just local G4IKZ (18km) and EA8BVP (2986km) spotting me and not a single spot of my 500mW WSPR beacon on 10m from the USA. If there is to be a marginal opening later, I would expect this around teatime here i.e. soon.
 
I have been getting reports from G4IKZ that my WSPR  dT (timing) is way out (3 seconds). I seem to have no issue getting lots of spots usually, but I wonder what errors in dT others might be seeing? My usual set-up is a stand-alone 10m 500mW WSPR-AXE-CW beacon which I manually reset to internet time after breakfast every day. I do this spot on an even minute but I could adjust this (earlier or later) if this resulted in a better dT error. Please let me know if you also see large errors as reported by G4KIZ.  On 472kHz I use a PC/FT817/transverter. The PC is reset to internet time every 5 minutes using atomic.exe software.

UPDATE 1940z: Well, at the moment it looks like there will be no 10m WSPR spots of me from the USA today.  It is still possible that the could be a very short opening, but this is now improbable.

UPDATE 2055z:   No USA stations spotting me at all. A dire day on 10m WSPR. These were the unique stations in the last 24 hours.  The USA stations shown here were yesterday.

  1. might be active over the long weekend, more activity on Topband and more DX. There might be a bit more wire in the air now that the wind has passed.

    Did you see AP1RIL on MF WSPR? Telegraph (nearly radio / early pre=cursor) had a bit about wraping Longleat visitor's cars in bubblewrap to protect cars from monkeys .

    Perhaps we can have bubblewrap suits to protect against Ofcom?
