Mark,
I hear you. As an engineer I basically worked a sedentary office job during the
day and operated at night. When I retired I figured I would have more time but
I make it a point of being active. My wife and I take a hike very day. When out
of the house I try to operate portable therefore
I agree with you, Mike. It would be interesting to survey the average age of
our top-band subscribers (Tree, was this done already and I missed it?)
I started on top band in 2007, and really started chasing DX in 2009-2010
season (it was a good one!)
But that was 10 years ago. Between
Interesting. After reading that Spaceweather article, I had my radiation
detector app running on my tablet two days ago, and there was no doubt that
it was picking up significantly more counts per minute than I've ever seen!
However, the background count last night had dropped to almost normal,
I attribute the decline in participation to the raising noise floor and the
aging population of ham radio operators.
I been operating 160 since I moved to the present location form a city lot in
1998 and have noticed the noise level constantly raising. I've been successful
in noise sources in
Hi to everyone,

(GCRs) result in more electrons down low in the ionosphere (from
collisional ionization) - where ionospheric absorption occurs. So one would
think that the more cosmic rays, the more absorption - which is

well that came out unreadable! try again.
scores over the past years: 2009 618,000, 2010 752,000(83 countries),
2011 600,000, 2012 324,000, 2013 367,000.
2014 312,000, 2015 319,000, 2016 278,000, 2017 372,000, 2018
384,000.
2009-2011 were very good years
for what it's worth here are my scores from past years:2007 247,0002009

certainly scores were dependent on conditions that weekend but no
Could be that good conditions are just ahead but they better hurry up. The
6 years of >100k scores in the last cycle versus none so far in this one
seems to indicate something is very different about this cycle compared to
the last one. If this cycle is 11 years, we should have seen much better
But doesn't the graph referenced in your link
https://spaceweather.com/repeat_images/crinfo2.png indicate that the
greatest strength from cosmic rays was 2009-2010, when trans polar
conditions were at their best, Bill?
I'd defer to K9LA's comments in a heartbeat, but isn't the one (the
primary?)
Not bad but definitely not great either. Nobody (USA SOHP/160) has broken
100k so far in CQWWCW for this cycle low. There were 6 consecutive years
over 100k (2005-2010) for the previous cycle low. K9LA may comment but I
understand cosmic rays cause increased absorption just as high solar
During the last minimum, there were times when high northern latitude
stations in zone 17 and 18 would be very strong for long periods of time
here in southern California. Last Sunday morning during the ARRL 160
contest there was an opening that had that very low absorption
characteristic
Please don’t laugh at my puny numbers.
This season I have worked 5 European stations from my noise challenged postage
stamp lot in San Jose. The last time I was able to hear and work a European
station at my QTH was 2009.
I’ve worked more DXCC entities on 160 this year than I have in any
This morning conditions were close to, not quite as good as 2008 era.
A5 was a good signal drawing a big crowd, 4S7 good signal even after
sunrise,
lot of Asian Russians, EU Russians, EU from north to G, F, SV, etc
copyable,
EA8ZT called me with 599 plus signals just after my sunrise, lot
This morning - I put 21 Europeans in the log.
Guess conditions are not that bad.

This could account for relatively poor conditions on 160 despite the low SF
and K indices:
*COSMIC RAY UPDATE:* Something ironic is happening in Earth’s atmosphere.
Solar activity is low–very low. Yet atmospheric radiation is heading in the
opposite direction. Cosmic rays percolating through the
