I am partly through this paper. What may not be obvious at a glance are the 
statistics and math that underlie the analysis. I may as well be in for a 
penny, in for a pound. I had thought before reading this paper that there is a 
good reason to think that the sunspot activity will approach 250, +- a really 
big window. This is only slightly higher than McIntosh's 233. I think that I 
disagree with his model, but agree with his math and his conclusions. I 
encourage anyone who has an interest here to read the various papers. They will 
not be casual reading.

I have had many successes and failures over the years. One thing that seems to 
put me in a smaller class of physicists is that I don't mind being wrong. I am 
passionate and enthusiastic about my beliefs, and ready to change them 
immediately upon seeing proof that I am wrong. A while back I was pursuing a 
particular math approach to finding (mumble, mumble, space plasma physics), and 
one of the senior PhDs said that "some really f*** smart people" had developed 
another approach, and I'd better spend my time understanding what they did, 
rather than go off in a different direction. My math later replaced that 
alternate approach. You need not think that this implies that I am any brighter 
than any one here, but that it points to a closed mindedness that really 
surprises me in the scientific community. One of my friends is fond of saying 
that he thinks I am bright enough to have 2 brains...one the size of a BB, and 
other just a tiny thing ;-) I appreciate the humor. We can also be
  found in public venues declaring to one another (wink, wink) that we are so 
smart that our IQs are not just in the 90s, they are in the /high/ 90s ;-)  I 
have seen many insights come from folks with the equivalent of HS diplomas, and 
don't place much stock on the "paper" I have filed somewhere. That's why it's 
not on my wall.

At any rate, we will all hold our breaths. Even if Cycle 25 is a banner cycle, 
my rotating-spinning-toroid sun model may not be correct. I can live with that 
;-) And the cycles are good cycles-bad cycles, because what might be good for 
hams will certainly be cause for concern for those operating satellites and 
orbiting people containers. Now back to our regularly scheduled entertainment...

Thanks so much for posting this...I have been contacted off forum to discuss 
this, and I have been considering how to distill the information from 
historical data. There is a lot of processing involved. I will read this before 
I respond. This is not the first time that I have disagreed with mainstream 
physicists on some subject. That's what makes the world go 'round ;-) But 
disagreeing is not the same as being correct, so it remains to wait it out and 
see. In particular, I have disagreed in the past based on the difference twixt 
micro- and macro-view of some system (such as the sun, or the solar wind-earth 
interaction).

Re: [Elecraft] Sunspots!?!?

[Fred Jensen]

The contrarian view is based on a correlation analysis of the distance 
between "termination events" and the activity of the following cycle.  
The earlier [lower] estimates for Cycle 25 were based on physical solar 
dynamics.  I remember Cycle 19, I was a teenage ham with a new Extra, 
and I of course figured this is the way it always is and will be.  Then 
reality intervened. 😁

Re: [Elecraft] Sunspots and the K2, K1

[Jim Sheldon]

I had just gotten my K2 after having problems with a close neighbor ham 
that ALWAYS ran his 2KW amp full bore, even for crosstown QSO's, had an 
early  Yaesu FT-1000 with super key clicks.  He refused to do the key 
click mod (so he could grab and hold a frequency in a contest without 
people encroaching on it).  He overloaded a Yaesu FT-897 which I 
replaced with an ICOM 706 MKII and overloaded that too.  I ordered & 
built a K2 which took care of the overload, if not the key click 
problem.  I loved that K2 and had a lot of nice successes with it.


First off, I was working 160 meters one early morning, heard a Caribbean 
station (will remain nameless to keep from shaming him) calling CQ (not 
CQ JA or CQ DX) so I called him.  He acknowledged but refused the 
contact because he said he was only working JA stations.  I continued to 
listen to him call CQ for a while when a JA station answered him.  After 
he returned the JA's call, the JA station said "Sorry, I'm only working 
USA stations this morning and then the JA called me!  - Wow.  I was only 
running the K2 at 5 watts on 160 and that was totally unexpected.  Had a 
nice chat with the JA station (got the QSL card to prove it about a 
month later).


Later, I inherited a tidy sum of money when my favorite Aunt passed away 
and got a full K line.  Final to the story, the FCC got on the local ham 
with the key clicks so he had to fix them, I now had a KPA500/KAT500 
behind the K3 and in a contest I could operate within a couple KHz of 
this guy with the K3's attenuator on and not have a problem 
copying/working weak signals.  Back when he was overloading the Yaesu & 
ICOM rigs I had, I asked him to turn the amp off in local QSO's but his 
comment was "Get a real radio!".  Well after I got the K line and ran 
the amp in contests, he asked ME to turn MY amp off.  My response to 
that was -- "Like YOU said, get a real radio!".  Shortly after that he 
moved out to a farm he inherited about 35 miles from me and I haven't 
heard him since - LOL.


Speaks extremely well for the Elecraft line's strong (even extreme) 
signal handling capability.  It was good, but not perfect with the K2 
but even better with the K3 and now a K3S.  At 78, I doubt I'll ever 
have a K4, but I fully expect the K3S to just keep on truckin' as it has 
for the last few years.


Thanks Elecraft for some of the best rigs of the age.

Jim Sheldon, W0EB

[Elecraft] Sunspots and the K2, K1

[Louandzip via Elecraft]

I built my K2 and then a K1 during the solar maximum in 2001/2.  One of the 
hallmarks of the K2 is it strong signal rejection.  It was one of the best 
radios of the time and is still among the better radios today.  The K1 isn't 
really in the same league, but it's no slouch either.  The worst test I put it 
to was operating in CH on 40m during a contest weekend during a business trip.  
Huge wall to wall signals but I was able to participate fine.
Somebody mentioned switching in the K1's attenuator.  Originally, doing so 
created a loud audio pop.  I came up with a mod to eliminate this, adding a RFC 
across the contacts of the relay K1 (coincidentally) which was adopted as part 
of the design.  

I grinned when I saw Wayne N6KR's terse response.  He's still justifiable proud 
and protective of his babies.

Re: [Elecraft] Sunspots!?!?

[Mike Morrow]

I've been a ham since before the solar peak of cycle 20, more than 50 years 
ago.  I used a K1 with its simple SA612 front end during the peak activity for 
cycle 23 and 24.  The problem that you have conjured is non-existent for 
practical proposes.  There is nothing but joy to be had with any QRP rig in 
times of good solar activity.  (I also used K1SWL's DSW-20, -30, -40 and MFJ 
Cubs for 40, 20, and 15 meters...all rigs with very simple front ends.  I 
experienced no problems  either.

FWIW, cycle 21 (peak November 1979) was my favorite.

Re: [Elecraft] Sunspots!?!?

Doug,

I lived through cycle 19 of the sunspot signals, and did not find any 
problem with receiver overloading at that time.  We did not have the 
Elecraft gear at that time, but what we had was not up to the 
performance/protection that is typical for Elecraft.  Receivers have 
gotten much better in dynamic range and lowered MDS in general and 
Elecraft rates near the top of the heap.


The AGC in the K2 and K1 (and K3/K3S) can handle the strong signals with 
no problem.  It is not much different than reports of performance during 
a contest where there are strong signals and weaker signals.


If we have a strong sunspot cycle, the weak signals will get stronger

K2, but in general, is there a realistic problem with overloading of the front 
end? Or, assuming that you can hear signals from all over, will the 
selectivity, etc., be sufficient?

Doug, W0UHU.

[Elecraft] Sunspots sunspots sunspots

[Andy Durbin]

Many more EU station on 15 m today than I have seen for a while.  17 m gave me 
a QSO with OD5KU for an ATNO earlier in the day.  Even earlier than that I 
worked JA on 160 m for the first time despite my hopelessly inadequate 5 ft agl 
antenna.

I thought my luck must have changed but I suppose sunspots could have been 
implicated.

Re: [Elecraft] Sunspots - More patience required . . .

Those of us who study solar physics actually view the 11 years as half of 
the 22 years it takes for the magnetic cycle to complete.

A peak or minimum is not a complete cycle.

This month’s Scientific American has an interesting one-page article on 
sunspots.  The 11-year cycle (the Schwabe cycle) is the one we tend to focus 
on, but there are 88 year cycles (the Gleissberg), occasional 200 year peaks 
(Suess-DeVries), and a 2,400 year (Hallstatt) cycle as well.  The longer 
cycles look like modulation envelopes with the shorter cycles constrained 
within them.

[Elecraft] Sunspots - More patience required . . .

[Dauer, Edward]

This month’s Scientific American has an interesting one-page article on 
sunspots.  The 11-year cycle (the Schwabe cycle) is the one we tend to focus 
on, but there are 88 year cycles (the Gleissberg), occasional 200 year peaks 
(Suess-DeVries), and a 2,400 year (Hallstatt) cycle as well.  The longer cycles 
look like modulation envelopes with the shorter cycles constrained within them.

It seems from the graphic that we are only a few hundred years off the low of 
the 2,400 year cycle as well as suffering the bottom of the 11 year.  The last 
peak of the 2,400 year looks like it was at about the year 300 CE (a/k/a  AD).  
So the next Hallstatt peak should be due in around 600 years, if I am 
interpolating from the graphics correctly.  I should probably replace all the 
coax by then.

The article is non-technical but visually striking.  I have no way to post it, 
and shouldn’t without SA’s permission anyway; but I can send a pdf copy by 
return e-mail attachment if anyone wants one.  Request off line please since 
this is sort of OT.

[Elecraft] sunspots again

The current ARRL propagation newsletter contains a link to a good summary,
with just about the right amount of technical detail, of recent work
regarding the future of sunspot cycles:

Re: [Elecraft] Sunspots are back???

[Jim Miller KG0KP]

I also do not get to my radio very often and have been operating psk mostly 
recently.  What I have seen in activity in the evenings is that 20 has been 
staying open a lot later than previously and the activity on 40 digital has 
jsut not developed.  It would appear that the operators are staying on 20 
until tehy shut down.  I have made several contacts into the Ukrane at 
around 5000 miles on the 40 watts and that is on my Butternut vertical 
hiding in the trees down in the ditch behind my house (the tip of the 
antenna is about level with my front yard)..

10 has been open the past couple of weeks also (on phone even).

Re: [Elecraft] Sunspots are back???

[Ron D'Eau Claire]

I operate only sporadically, but for the past few months my CQ on 20 CW from
the Oregon coast is often answered by someone in central Asia or Europe just
about any evening I get on. Good signals too. From time to time, Australia
also has been showing very good signals as well as many other places around
Oceania. 

I'm running 100 watts into a 2 wave long wire.

Re: [Elecraft] Sunspots are back???

[Don Ehrlich]

Phil,

Yes.  I have seen NASA's and other articles to that effect.  Most recently I 
saw a NASA spaceweather article about the shift in the solar "jet stream" 
having just arrived at the 20 degree latitude point on the sun which is the 
position below which sunspots appear.  I'm going on memory here and may not 
have the story accuratly but the gist of it is that we should now start 
seeing more sunspots.  The solar "jet stream" moves south to north and back 
again on an 11 year cycle and its position south of 20 degrees latitude 
signals the creation of sunspots.

[Elecraft] Sunspots???

http://antwrp.gsfc.nasa.gov/apod/astropix.html

"Although fewer sunspots have been recorded during this Solar Minimum than for 
many previous decades, the low solar activity is not, as yet, very unusual."

?  Hmmm...  I hope the as yet part does not come to 
pass!
