Miracle Whip Yahoo Group

It is some while since I last used my Miracle Whip antenna, although I still moderate the Miracle Whip Yahoo Group which has nearly 1500 members.

Some of the SPAM I intercept is amusing.   More often than not these are to the group owner and promise me all sorts of sexual favours. I think they think the group is another sort!  How wrong they are. Most messages are filtered so it is rare for these to get to the group. As soon as seen, they are deleted. The group has a low tolerance of SPAM.

For those who don't know the Miracle Whip and its derivatives is a small, self contained QRP antenna. On the higher HF bands with a counterpoise it works quite well. My best DX using it indoors was with the FT817 to Argentina over 11000kms on QRP SSB. This was on 10m. It works as well as a 56 inch whip will do if well matched. Do not expect miracles!

Sunspots and 10m - Sat April 23rd 2016

Solar flux is 77 today and sunspot number 22 (K=2). The forecast for 10m propagation remains "poor".

WSPRnet - down again

In the last few hours I have tried (in vain) to visit WSPRnet to see where my 5MHz WSPR reached. It was down yet again. Many many times regular WSPR users have offered to pay for a reliable service. When WSPRnet is down WSPR is far less useful. I am still waiting!

At the moment the WSPRnet service goes for weeks working fine, then it collapses in a heap. Sometimes it is a long time before service is restored. I am unsure where the problem is but I hope it is soon repaired.

UPDATE 0912z:  WSPRnet is still down, after very many hours.

UPDATE 1236z:  WSPRnet is still down!  This is bad. I do wish the server owners and maintainers would get help.

5MHz through the night

Through the night I shall stay on 5MHz WSPR to see what happens. I am not familiar with the band so have no real idea what I should expect. I was quite surprised that my Par matched so well with the ATU.  So far the Icelandic spot remains my best DX on TX. I should try 10MHz sometime.

5MHz to Iceland and Finland

TF3HZ (1837km) and OH3TAM (1737km) have spotted my 5MHz WSPR. At the moment the former is my best DX on the 60m band. My antenna is still my 40/20/10m end-fed Par antenna via an ATU.  It is far from ideal on 60m.

UPDATE  2200z:   21 unique 5MHz stations spotting me on 5MHz WSPR in 8 different countries so far.  Don't you just love WSPR?

Britain and the EU - NOT amateur radio

Just watched the second Nick Robinson BBC2 programme about Britain and the EU. Some decent information in this series. If you are looking for real information,and NOT spin, I suggest you watch this on iPlayer or Catch-up if you can.

Pure commercialism - NOT amateur radio

Alibris UK makes me sick. Their latest "offer" is yet again offering a discount.

Oh yes. Pull the other one.

5MHz WSPR

Later today I may give 5MHz WSPR a go, although I need to check what frequency to use. I see that Romania has been granted access to a narrow part of the band. I hope CEPT (including OFCOM) allocate a contiguous 100kHz band at 5MHz rather than just the 15kHz worldwide allocation allocated at WRC-15. This band will be important in the quiet years to come. 15kHz is very narrow.

UPDATE 1020z:  I have just switched to 5MHz WSPR (both TX and RX).  I have had to go QRT on 10m WSPR and 6m WSPR because of rigs and antenna.

UPDATE 1100z:  These are the initial spots on 60m. 
UPDATE 1310z:  G8VDQ (93km) has been spotted on 5MHz. He must be active on many bands. My best DX on 5MHz WSPR TX remains 448km to Germany and The Netherlands.

Sunspots and 10m - Fri April 22nd 2016

Solar flux has reached a new low at 76 today. Sunspot number is 35 (K=2) and the forecast for 10m propagation remains "poor".

UPDATE 1000z:  Although I have been active on 10m WSPR TX for several hours, no spots as yet. I am also on 6m WSP where G8VDQ (93km) is regularly being spotted here.
