If you've wondered why the bands have been so volatile of late, it's because Cycle 24 just won't go away quietly. It seems that for the past several months, our planet has been besieged by one solar bombardment after another. Most of it seems to be coming via Coronal Hole Streams.

This UV image from NASA's Solar Dynamics Observatory satellite clearly shows the large coronal hole presently facing earth. The arrowed vectors represent material spewing from the hole, with much of it earth-bound. The material from this hole is expected to arrive between April 21-22, possibly causing more auroral activity.

Our Sun's latest rotation is showing several new large sunspot groupings, all very capable of unleashing a new round of solar flares and associated disruption ... if nothing else, Cycle 24 is persistent!

Peeks at the geomagnetic activity for April 16th illustrate just how active things have been of late ... making the high HF bands sound like the middle of the night as well as making LF and MW propagation depressing.

The software gurus at NOAA have been busy once again, this time revamping several of their visual models to an 'animated' mode. The Ovation Auroral map is particularly interesting when run in this mode as it shows the auroral field's activity visually over the past 24 hours. The display gives one a new appreciation for the dynamics of such large scale events:

An auroral event on Thursday evening gave 6m conditions a bit of a kick in the backside on Friday afternoon with signals from southern South America making it into various regions of the U.S. including the PNW, usually left out of such affairs. At one point, CE2AWW was hearing / working both the west coast (W7's) and the east coast (VO1's). Sporadic-e was definitely involved on the west coast end as the band was open to California / Nevada for most of the day.

No one can be certain of what lies ahead for Cycle 24 but it's certainly not going away with a whimper!

Having an EchoIRLP node here at home allows me the option of communicating with the XYL (who holds a Tech license) when I am on the road. I found this very useful when I was stationed in Korea. With the time difference, the end of my day was the beginning of hers. I could check APRS to see when she started her morning commute and then connect to my home node. This allowed me to check in with her as well as saying “Hi” to the kids.

With the Summer Trip, the XYL will not be with us the whole time. Therefore, IRLP may well offer a solution.

Time change will not be a significant factor – which means the best times to schedule IRLP QSOs with the XYL would be during the commute times. That should work fairly well because I do not plan to be on the road either too early in the morning or much past the late afternoon.

What is the availability of IRLP nodes along the route I am taking and will they be near our overnight stops? Enter the ARRL’s Repeater Directory. I remember my dad almost always having the shirt-pocket version of this directory by his easy chair along with his HT and a mechanical pencil that he used to make notes. I have consistently followed his lead, although I usually keep a copy in my truck as I am not too much of an HT guy. Another difference is my excitement about the Desktop Edition of the Repeater Directory. I find the shirt pocket edition way too tiny and difficult to use. The Desktop Edition is the Business Class of directories…. spacious, roomy, and comfortable.

I took advantage of ARRL’s birthday coupon to purchase the 2015-2016 directory and am using that to start my IRLP node research. Without digging up my maps and looking too much at the surrounding areas, here is what I found:

Sioux Falls, SD, IRLP Node #7346, 444.2, 82.5
Gillette, WY, IRLP Node #3307, 449.75, 123
Cody, WY, IRLP Node #7194, 146.85, 103.5
Great Falls, MT, IRLP #7908, 147.3
Great Falls, MT, IRLP #5670, 147.36, 100
Bozeman, MT, IRLP #3692, 448.35, 100
Billings, MT, IRLP #3398, 449.75, 100

What I will probably do is use my home node to connect to these nodes to see if they are in operation and get an idea as to what their coverage areas are.

THIS WEEK'S NEWSCAST

Magnetic loop antennas can be very effective, small, antennas. They work well and are ideal for modes like WSPR, JT65, JT9-1 and PSK31 where frequencies don’t have to be moved much. Their main disadvantage is they are narrow-band so require retuning if moving very far in frequency and they are directional.

As ever, Steve G1KQH has been tracking down bargains – in this case motors that could be used to either tune or rotate loops.

I saw a link to this video on Peter VE3HG's blog.

The devil is in the details and some might complain that some of the details in this commercial are not paid attention to - no call signs for instance. And some of the concepts are a bit stretched - did he buy that amplifier himself?  But the basics are sound, and I think this little boy, Sam, captures our Amateur Radio spirit to a "T". At least I think so. What do you think?

It's been many years since I've cruised through the SW broadcast bands but of late I've had a yen to tune through some of the low band frequencies ... 5-6MHz. In searching some of the helpful online frequency references, the Short- wave info site in particular, I was reminded of Canada's tiny voice still whispering away on shortwave, even after the demise of Radio Canada's shortwave presence in 2012.

Apparently there is still activity coming from CKZU (6160KHz), CKZN (also on 6160KHz), CFVP (6030KHz) and CFRX (6070KHz). These are all low-powered (100-1000W) relays of local AM station content and make for interesting DX targets for listeners.

The nearest to me, CKZU, is directly across Georgia Straight and line-of-sight from me. It relays the local AM-band powerhouse, CBU-690. Needless to say its signal is very strong.

With its antenna system located on the mudflats of Richmond (Steveston), near Vancouver, it should get out pretty well despite its 500W power limit.

The antenna system, I am told, consists of a four pole (wood) support for a two-element wire beam of sorts ... one element being the dipole driven-element and the other a reflector. From the looks of the orientation I would say that it is beaming south-east towards the central USA.

Are you able to here CKZU on 6160 from your location? Its overwhelming strength here blocks any chance for me to hear its east-coast cousin, CKZN in St. John's, Newfoundland, rebroadcasting local CBN. If you are in the eastern half of the continent, perhaps you are able to here CKZN's 300W signal?

CFVP is in Calgary and relays local CKMX on 6030 at just 100W. I can hear a carrier there in the daytime but long before my local sunset the frequency becomes dominated by Radio Marti (in Spanish) from Florida ... perhaps you can do better from your location.


Lastly is CFRX, relaying CFRB from the city of Toronto, on 6070. This gets out well and is heard here even before local sunset at 1000W.



It appears that most of these stations have, at one time or another, been slated for decommissioning, and have only been saved by the dedication of station engineers who basically maintain these on their own time, with station owners paying the rent and electricity bills.

Please let me know if you are able to hear any of the 'lonely' Canadians on 49 meters.
