Solar storms VS QRPp

This week we all have seen sunspot 1515 working overtime producing solar flares.  It has been some time since a sunspot has consistently produced M class flares sometimes 2 or 3 in the same day. As amateurs we like to see rising sunspots, rising Flux numbers and a falling K index. ( as a side note this link is a great index for all those propagation words you wonder about)...BUT....along with an active sun also can come increased solar flare activity, increased solar wind which can bring a downturn for radio conditions. As a QRP/QRPp station I take these conditions as a challenge I also understand that during these times for me DX may mean contacts in the U.S. This week I have tried to get on the radio for a short time each evening. Using the Reverse Beacon Network (RBN) has been a great help giving me an idea which bands were open and just where my CW signal was being heard.  Below is the results of one of my RBN sessions
 20m report
NY3A  in P.A.         11dB
K3MM in M.D.        21dB
WZ7I    in P.A.       18dB 
K1TTT in M.A.       11dB
KB9AMG  in W.I.     9dB       

Most of the time I would be heard in Europe but with conditions the way they are the U.S. seems to be my DX destination for the time being.  I fired up the K3 along with DxLabs. Right off the bat I saw lots of spots for Europe but was not able to hear them on this side of the pond. I then heard an S5 signal from SM5EPO from Sweden. I knew conditions were not that great and after all the RBN confirmed that on 20m's it was the U.S only.........So I dropped the K3's power to 100mW's Heee Heee Heee and gave it a go. SM5EPO came back to me and with a few repeats the contact was complete at 39,111 miles per watt. In the past when conditions were good and I was making QRPp contacts and logging the miles per watt I wanted to see how I would do if conditions were not ideal.

  1. Congrats! Well Done. I was lazy the last days, so I have to fire up my K2 and give it a try. But you are hard to beat ;-)

  2. Good afternoon Hajo, yes do fire up the K2 I just spend about 30 minutes to an hour max at night. As for being hard to beat I just keep surprising myself. I just received the Hendricks 41dB attenuator on Friday I will have that together soon. Then it will be into the depths of under 100mW's!!!

  3. Hello Mike, Yes, every time it's a big surprise. Congrats. With the Hendricks attenuator you can boost your Miles per Watt score. Check out your S-meter. hi 73, Bert

    1. Good afternoon Bert, the Hendricks attenuator has arrived and is awaiting assembly. As for the S-meter yes at the time of the shot it does not the S-6 of SM5EPO as the shot was taken after the QSO and the logging of the contact.

  4. Hi Mike, it's always a surprise, you'll never know what to expect. 73 Paul

    1. Hi Paul, yes that is the nice thing about QRP and QRPp it can be full of the unknown.

  5. Hi Mike. I haven't had a QSO with Europe in several (or more) weeks. Disappointment this summer. 73 Dick

    1. Hello Dick, the sun can play games for sure and it has been. The IARU HF contest is next weekend shine up the key and give it a go for some contacts across the pond. I find contests to always be active for a QRP station to get contacts.
