The latest 60M activity news as published in the SARL news bulletin on Sunday 13 April 2013..... :)

5 MHz ACTIVITY WEEKEND ON 10 MAY 2014

A 5 MHz activity weekend will be held 10 and 11 May.
A number of prizes can be won for stations participating in contacts on 5 260 kHz and submitting reception report of the KART beacon on 5 250 kHz which will operate in WSPR, CW and PSK 31.
Full details will be published next weekend and after that on the SARL Web.

Then something on the SARL annual awards dinner held last week Saturday evening (12 April 2014) KARTS received the ICOM Excellence Award, the “premier” award of the SARL for their dedicated support of the SARL's 5 MHz initiative and propagation study project.

I put a request out on the SARL forum for people to listen on WSPR. The response has been excellent!

People who have contributed in providing spots:
ZS6AF - Nelspruit
ZS1AGF - Cape Town
ZS5JT - Richards Bay

Here is a link to the SARL forum posting.
www.sarl.org.za/forum/topic.asp?TOPIC_ID=11853

5Mhz is more suited for medium range comms and although we are enjoying the DX contacts being made using WSPR, we need more local information.

Here are the latest maps representing the last 24 Hours (The colours of the lines are meaningless).

Really good news. We are cooking along with WSPR on 60m.

Great news on Friday night we had a record number of spots on WSPR. At one stage we received 8 spots in one transmission, quite a feat on its own! However not to be out-done we broke another record last night. Werner DF6MK, last night, got 14 spots with successful decodes in a row. This is quite an important achievement as it demonstrates the consistency of the signal. I don't mean that the signal is specifically good, just that what ever the signal quality is, it is consistent.


Record = 8 spots in one tranmission
Record = 14 Decodes in a row from one station in Europe

Here is the latest image from 18:32 (GMT) last night from Werner DF6MK

Hi Stewart,

Here comes a picture from the 18.32 UTC spot.

Werner, DF6MK

Notice the funny line at +-40Hz (circled in yellow), that's us!
