Question on Propagation

[VK2FAK]

Hi all....

Have been looking at wspr on 30m the last day or so....when the wind has not be a problem..

Looking at it tonight.....I was being copied by KL7UK ( Alaska Coast) @ -9 and -7 using 5 watts......but was unable to be copied by any West Coast US stations...on the Map there is not a lot of distance between the two...there is plenty of room between -7 and -27 for those US station to get a copy......

The propagation maps suggest the signal should have been getting through.....

VK1UN/1 was also being copied but at -25 using 2w...but was also not hearing or being heard by many east coast US stations...

Any Idea..?

HI John

Sounds a bit strange, but I cant explain why that would be. Just something to take note of I guess and see if it happens on a regular basis or not.

If the stations at the other end are experiencing more noise, from local or regional sources, reception of weak signals would likely be masked by the noise.

Posted as one explanation.
