As seen on QRP-L this morning, by Paul NA5N:

Solar flares and a heads up

Gang,
Ole Sol has awoken with three large flares in the past 18 hours, an M3, M6 and an X1.  There may be more to come.  The active solar region is in the center of the sun, looking right at us, meaning any CMEs (and future flares/CMEs) will most likely deliver a shock wave to planet Earth on Friday and/or Saturday with some geomagnetic storming.

But more exciting is how these flares have gushed waves of ionizing radiation into our ionosphere. The average solar flux for the past 90 days has been a count of 150.  Today’s flares increased the solar flux to *237*, though short lived as local sunset occurred not long after in North America with EU already in the dark.

However, the prediction for the next two days is a solar flux of 195.  This is about the highest it has been this solar cycle and sufficient for 10M openings in local daylight hours.  So for those of you snow bound, freezing your coax off and otherwise bored Wednesday in the Eastern U.S., turn on that rig during daylight hours and enjoy some very likely good conditions from 20-10M.  Daytime conditions should be very favorable until late Friday, when the shock wave from the X1 flare is expected to arrive.  The CME left the sun at about 1,100 km/sec – a pretty decent shock wave.  NOAA is predicting a moderate geomagnetic storm, but it could get worse, though short lived.

These favorable conditions apply to all areas, Europe, the Americas, Asia, Australia, etc. during daylight hours.  The proton count is also fairly high, meaning signals may be very attenuated in the polar latitudes and causing some fading (QSB) in the middle latitudes.  If the proton count remains high and the CMEs hit Friday night, it could mean some impressive northern lights, perhaps extending into the northern tier of U.S. states or northern EU (depending on when it hits).

If you’re new to ham radio or QRP, check out 15M and 10M next couple of days.  If those bands are open and the solar flux indeed comes in around 190-200, you should be able to easily work some nice DX with your 5 watts.  This is the first such opportunity I have seen in a long time.  Unfortunately, I will be at work tomorrow, installing some experimental 74 and 300 MHz receivers onto some VLA antennas.  Maybe I can sneak my 817 into one of the tool bags?

Let us know if you snag any good catches, or how conditions sound at your QTH. The way I figure it for right now … turning on your 100W coffee pot and 500W shack heater to get your 5W on the air will be worth it -hi.

GL to all.
72, Paul

QRP – When you care to send the very least!

Like a lot of you in other places, we’ve been on a bit of a temperature roller coaster lately.  Last weekend, after Christmas, it was up in the mid 50s (12C) here in New Jersey. This weekend, after New Year, we went as low as -3F (-19C) and our high for the day on Saturday was about 20F (-6C). That was just two days ago.

This morning, when I drove into work, it was 54F (12C).  Now, after lunch, it is 38F (3C) and the temperature continues to free fall.  By the time I leave to go home, I am sure that the temperature will be somewhere around the mid-20s (-4C).  And over the next 24 hours, we’re supposed to get some of the coldest weather we’ve had here in over 20 years.  The temperatures are expected to go below 0F (-17C) at night again, but this time with wind chills way lower than that. Tomorrow’s high is supposed to be only somewhere around 11F (-11C).  But then, later towards the upcoming weekend, it’s supposed to warm up again to more like springtime temperatures.

Stop the roller coaster, I want to get off!  I am NOT a big fan of the cold, but I sure wish that it would already stay one way or the other for a while.  It’s winter time, so even though I don’t like it, I can deal with the cold for a bit.  This teasing of Spring, and then the plunge back into the deep freeze is just cruel.

On a radio note, I was looking at the solar conditions yesterday and I was licking my lips.  High SFI, a goodly number of sun spots and low A and K values. Having some free time for a change,  I got on the air, expecting to hear a lot, and for a while I thought ALL my antennas were on the fritz!  Nothing much heard yesterday, and nothing much worked.  What a let down.  At first I thought maybe everyone was working the ARRL RTTY Roundup, but even RTTY signals seemed sparse to me.  In a major RTTY contest, we often get interlopers all the way down to the lowest of the low part of the bands. Yesterday, all the RTTY stations that I heard seemed to be staying way above the .060, QRP Watering Hole areas.

Maybe all the RF is freezing from the cold air and is just dropping out of the sky.

QRP – When you care to send the very least!

It was about 35 degrees (2C) when I set out for the Jeep at lunchtime. Not as breezy as yesterday, but it still felt nippy. Though that was a lot better than the 19F (-7C) that I woke up to earlier in the morning. New Jersey is not supposed to be quite this cold around this part of November!  Anyway, once again I operated from inside the Jeep as opposed to standing outside.  I didn’t need to turn on the heater as my upholstery is black and on a sunny day like today, the car can get rather warm on the inside. Solar power at its best!

The bands may still be in good shape, but once again, activity seemed sparse. Maybe it was because I wasn’t hearing 25 kHz wide DXpedition pileups, so it just seemed more quiet. I called CQ and was awarded with a nice QSO with Terry W9UX (who’s name I remembered, BTW!) in Madison, WI.  Terry is an avid and active QRPer, so I was rewarded with a 2X QRP KX3 to KX3 QSO (THAT’S a mouthful!).  We talked for a bit, and then, just as I was mentioning how the bands seemed to have lost some of their zip lately, wouldn’t you know?  We both QSB’ed from 589 to maybe 219 (generous).  We were both at ESP levels and couldn’t hear each other for anything as the band dropped out on us like the proverbial lead balloon.

A lesson re-learned, as sometimes I can get a bit too wordy in my QSOs. When band conditions are subject to volatility, it’s best to stick to a lot of our CW abbreviation lingo and not spell too much out, word for word.  CW abbreviations – the original texting shorthand!

TNX QSO – BCNU AGN SOON,  73 ES GB

QRP – When you care to send the very least!

I went out to the car during lunchtime today.  Temperatures here in New Jersey have cooled down. It was only in the upper 40s here (about 9C), so instead of standing outside and operating from the rear hatch of the Jeep, I sat inside to keep out of the breeze.  Activity on 10 Meters seems to have gotten sparse. I still hear signals, mind you, but they are not as loud and not as “wall to wall” as they were just a few weeks ago.  I don’t know if it’s that the band has changed a bit, or perhaps the novelty of 10 Meters coming back to life has worn off. In any event, I found myself on 17 Meters today, tuning around the band to hear what I could hear.

I worked EI13CLAN, whom I worked last month on 10 Meters.  He was very strong, a very legitimate 599.

The tuning around some more, I heard XF1P calling “CQ DX UP”.  OK …….. Mexico.  But the pileup was huge …… HUGE!  I wasn’t exactly sure why. Mexico is not exactly what you’d consider to be the rarest of rare DX.  I reasoned that with a pileup that big, something that I was unaware of must be “up”.  Additionally, I  took it as a personal challenge. Could a QRP station running 5 Watts to a Buddistick possibly bust that pileup?  XF1P was 599, but just barely. There was QSB to boot. I was reasonably sure that my signal would be audible on his end, but with that pileup, would I get lost in the sauce?

I sat there for about  20 minutes, listening and sending out my call. The KX3, with it’s Dual Watch feature, almost makes it unfair.  I was able to follow XF1P along the band as he would move slightly after answering each station, XF1P in my right earbud and the station he was working in my left earbud. It just became a matter of sensing his pattern and setting the transmit VFO just a tiny bit higher after each call. Also, I had to time the sending of my call –  not transmitting immediately, but waiting for the pileup to fade “just” enough where my call would be heard among the cacophony of all the true 599s that he must have undoubtedly been hearing.  Finally, I heard him send back “W2L?”. Wouldn’t you know it? True to form, all kinds of stations without a “W”,” 2″ or an “L” anywhere in their calls began blindly transmitting.  Not deterred,  I stayed with it and threw “W2LJ” out there just a couple of more times and was rewarded with a confirmation.

Coming back from lunch, a quick peek on the computer before resuming work informed me that XF1P is an IOTA DXpedition to Partida Island – NA-124 located in the Gulf of California off the coast of Baja, Mexico. It is an uninhabited island, so I guess that makes it rare as IOTA goes.  The pileup of IOTA devotees was intense, but I accepted the challenge with 5 Watts, took advantage of XF1P’s exceptional ears, and got through!  That’s always a good feeling. And it also goes to show, that if I can do this, then YOU can do it too. It just takes some persistence and a lot of listening.

QRP – When you care to send the very least!

The season started tonight on 80 Meters. I worked Tom KV2X in NY rather easily. Then I located Jay KT5E in CO, and called him pretty much non-stop for the next hour. Sadly, it was not to be. Conditions didn’t favor me, and out of the three regular NJ Hounds, only Al W2EEW, got a two-fer. Both Charles W2SH and I nabbed only one pelt each.

Today during lunch, I was disappointed to hear that activity on 10 Meters seems to be waning. I didn’t hear many CQers, so I shinnied up to the QRP Watering Hole at 28.060 and called CQ for a bit myself. I was answered by Gerry EI5HJ. It was a nice QSO, but copy was a bit tough, with lots of QSB. 10 Meters may still be open, but the band seems to be in a bit rougher shape than it was just a mere week ago.

After my QSO with Gerry, I slid on down to 17 Meters, where I worked Cedric, CT3FT on Madeira Island. Band conditions seemed a lot better there. There was also more activity there than there was all last week.

QRP – When you care to send the very least!

was quite packed today at lunchtime!  Which was absolutely, positively fantastic!  In fact, it was just a little difficult to find an empty frequency. So for a change, I listened for a CQ instead of calling, and I ended up having a nice QSO with F5LAW, Yann who lives near Lille, France. Yann was using his Kenwood TS-480SAT at the 5 Watt level.  He was pushing those 5 Watts into a 4 element Yagi antenna.  I gave Yann a 549 and he gave me a 559.  There was some QSB, but the entire QSO was solid copy!  And on his last exchange, Yann’s signal had peaked to a solid 589.

Yann had commented that he had survived Autumn storm Christian with no damage to his property, although some of the surrounding area was not as lucky.  That reminded me that it was just one year ago today that Hurricane Sandy did her number on New Jersey and the rest of the Mid-Atlantic coast:

On the HF bands – 10 Meters was great again during lunchtime and I had no problem working Serbia, Italy, Belarus and Germany.  All the QSOs were great; but I had two in particular that were gems.

The first came at lunchtime on the 10 Meter band.  After working some DX, I decided to go to the watering hole of 28.060 MHz.  There I heard a weak CQ – DF7IS, Klaus in Kandel, Germany.  Klaus was running 5 Watts from his Icom IC-703 to a sloper.  I just love 2X QRP QSOs, especially 2X QRP DX QSOs!  We gave each other 559 signals and copy was solid, even though QSB was a little trying at times.  But the KX3 pass band tuning really helped me notch Klaus’s signal and I had great copy throughout.

The second gem came after I got home.  With dinner done and a Harold walk yet to come, I decided to hit the KX3 in my basement shack before the sun set.  10 Meters was a bit disappointing.  I heard a station from Guinea- Bissau, but the pileup was intense, and his signal was dropping like a lead balloon. 10 Meters did not seem as promising as last evening, so at that point I decided to switch over to 15 Meters.

At 21.020 MHz, I heard JA1NUT calling CQ.  I knew that this was Shin, because my bud W3BBO just worked him a few days ago, and I have heard of him many times before. Shin has the reputation for being a top notch CW operator, a sort of Amateur Radio celebrity, a Ham’s Ham.  Nobody was answering him, so I threw out my call.  Shin came back to me, and I gave him a 589.  His signal was warbly, like it was coming over the pole.  I’ve heard polar flutter before, and this sounded exactly like that.

Shin was running 500 Watts to a 4 element Yagi, and said he was trying to study the effects of the CME.  I knew immediately what he was talking about.  I learned about yesterday’s CME from Fr. Z’s blog of all places.  We exchanged other pleasantries and when it was my turn, I told him I was using an Elecraft KX3 to a vertical.

That’s when I got “KX3 THATS 5W RIGHT?”

I answered “YES 5W QRP TO A VERTICAL”

Shin came back again “AMAZING 5W UR 549 BUT SOLID CPY ALL THE WAY. ENJOY UR MIGHTY 5W LARRY”.

Wow – how cool is that?  Another walking on air moment! Amateur radio doesn’t get too much better than this.

Before I close for the night, I leave you with a video that was mentioned on the CW Ops e-mail reflector. Can you imagine having an antenna farm like this?  I have passed K3LR’s aluminum ranch several times on the way to and from Dayton. This is the first time I’ve ever seen a grand view like this!
