   The bulletin today is coming from Eugene, Oregon.   
       
   Average daily sunspot numbers rose over 20 points this week, or   
   about twenty-percent, to 119.4.  The average daily solar flux was up   
   3 points to 134.7.   
       
   Geomagnetic activity was quiet, with unsettled conditions around   
   August 2.   
       
   The NOAA/USAF prediction has solar flux at 135 on August 10, 130 on   
   August 11-12, then 125, 120, and 115 on August 13-15, then 110 on   
   August 16-17, then 95 on August 18, 100 on August 19-20, then 110,   
   115, 120, 125, 130, 135, 140 and 145 on August 21-28, then 140 on   
   August 29-31.   
       
   Predicted planetary A index is 5, 8 and 10 on August 10-12, then 5   
   on August 13-15, then 10, 8, 5, 8 and 8 on August 16-20, then 5 on   
   August 21-23, and 8 on August 24-25, then 12 on August 26, then 5 on   
   August 27 through September 14.   
       
   F.K. Janda, OK1HH sees quiet geomagnetic conditions on August 10,   
   mostly quiet August 11, active to disturbed August 12, quiet to   
   active August 13, mostly quiet on August 14, quiet August 15-16,   
   quiet to unsettled August 17-20, mostly quiet August 21, quiet   
   August 22-24, quiet to active August 25-26, mostly quiet August

   interested in transpolar propagation since I lived in Irkutsk,   
   Siberia from 1997-2004.  I'm thinking of putting together a ham club   
   at the school on Lopez Island and your name popped up with an   
   internet search.  There is so little on the web.  With sunspots   
   picking up, things (I would assume) will get exciting.  Do you know   
   of any EU or Russian/Ukrainian folks interested in such   
   propagation?"   
       
   I don't know, but if any readers across the poles or anywhere want   
   to contact AD7DR, look him up in QRZ.com, where you will find his   
   email address.  You will have to login, but getting an account is

   Larry Godek, W0OGH of Gilbert, Arizona wrote on Thursday, August 9,   
   "Spratly Island, 9M4SLL has been worked on both 20 meter SSB and CW,   
   along with CW on 15, with great signals.   
       
   Comoros Islands, D64K was worked on 15 yesterday at 2155Z.  Had good   
   signals into this area all the time he was on the air.  Typically   
   shortly after I get to work them, the band goes out.  Happens a lot   
   to me on 20 as well.  Just like Arizona is the last place to make a   
   QSO even though I hear the DX for long periods of time.   
       
   ZS2I was worked this morning at 1353Z on 20 CW long path.  He   
   couldn't hear me on the regular path so turned the antenna around to   
   270 degrees and he came up to over S9.   
       
   Talk about short hop, J68HZ was worked yesterday at 2224Z on 28.375.   
   He was working mainly 4-land and the east coast.  Surprised he came   
   back to me.   
       
   Same thing with HT9H on 18.073 MHz at 2215Z.  But then we had a large   
   storm front within 100 miles from the north around thru the east to   
   the SE.  Then 20 this morning has been excellent to the Pacific.   
       
   Yesterday in the morning we had a 6 meter opening, double hop into   
   Florida, Tennessee, South Carolina and Texas.  Nothing unusual about   
   the Texas stations as the area from EM00 though EM03 and EM10 thru   
   EM13 are the first hop for us.  They usually have loud signals and   
   are typically the first stations from the E we hear.   
       
   There would be an idea.  If it were possible, have any DX station,   
   maybe some of the rarer types, run a WSPR beacon.  If they can   
   capture your signal at 2W, then you've got a path.  But then there   
   is a lot of one way propagation that goes on isn't there?   
       
   Really been a pretty fair year so far for DX.  30 meters has been a   
   disappointment as has 10.  If it wasn't for 15 and 20 there would be   
   very little DX.   
       
   We print all the ARRL bulletins on a Model 28 TTY machine here.   
   Everything that is 45 Baud 60WPM anyway.  Really nice that ARRL   
   continues that mode.  Lots of hams around the country have real   
   mechanical TTY machines and look forward to running them several   
   times a week.  Keeps the oil and grease from getting old, kinda like   
   the body!"   
       
   Burton Boyd, W7IIT of Bremerton, Washington says his hearing isn't   
   as sharp as it used to be, and he can't always hear the WWV   
   broadcasts of geophysical data at 18 minutes after each hour.  I   
   advised Burt to get the info off the internet at   
   http://www.swpc.noaa.gov/ftpdir/latest/wwv.txt.
