Interesting day today (6 Oct), found a few minutes to review what I had heard on the radio and discovered that I had heard all 6 continents (for radio purposes Antarctica doesn't count) on 15m PSK31 in just 40 minutes.
This is the PSK reporter log for the period (with other entries removed):
SA: LU4LA 15m PSK31 10740 kms 13:59:03
OC: YC1DML 15m PSK31 11896 kms 13:57:03
EU: UA6ASU 15m PSK31 2976 kms 13:55:19
AS: 5B4AIK 15m PSK31 3300 kms 13:55:01
AF: ZS2DK 15m PSK31 9917 kms 13:45:54
NA: AB3LH 15m PSK31 3499 miles 13:19:56
I have no idea why the last (NA) one shows up in miles!
Quite impressive considering everyone is bemoaning the lack of sunspots. I have found that 15m has been wide open to JA and South America most days.
