After building the house here on Mayne Island, in the early 90's, it was several years until I was able to set up a dedicated station. In the meantime, I limited my radio activities strictly to listening. I had a nice Icom R-71A set up in a hall closet and spent my radio-time, mostly on weekend evenings, listening to maritime CW, HF aeronautical traffic and, of course, NDBs below the broadcast band. My HF receiving antenna consisted of three inverted-V's ... one for 160m, the second for 80m and the third for 40m ... all fed from the same coaxial line at the top of a 70' Balsam. It didn't take long to realize what an exceptional radio location I had, living right at the edge of the ocean, with dozens of miles of saltwater in most directions other than due west.


I really enjoyed following evening airline flights across both the North and South Atlantic, and in the early winter afternoons, following the commercial air-traffic all over Africa. Even though listening on 5 or 6MHz, I was amazed at how strong the signals from airliners over Africa at 30,000 feet or more could become, this far to the west. In the early mornings, directions were reversed and traffic from the far east, right into India, was fairly common. Often, small single-engine planes, usually run by various missionaries, could be heard while on the ground, taxiing at remote field locations and calling in via HF radio to request takeoff and flight-following.

Now, QSL's have always been one of my top radio interests and it wasn't long before I started sending and collecting verifications for both the aircraft and the ships I was hearing ... once I had figured out how to get my reception reports to their proper destinations. A very small portion of my 'utility' QSL collection is shown below. For the most part, it consists of PRC's or 'Prepared Reply Cards', with blank portions to be filled-in by the verification signers. Surprisingly, my return rate was around 90% and verifications were often returned with long, hand-written letters and numerous photographs ... especially from the ship RO's, as I suspect their days at sea were often quite monotonous. Even many of the military and commercial aircraft pilots would return a handwritten note along with the filled-in verification card, which I found even more surprising. It seemed that most were very surprised to hear that their radio transmissions were even making it this far and could be heard so readily.

Some of the most interesting catches came from the Pacific, with a large variety of ships operating out of Japan. There are probably still several maritime CW stations operating in Japan. Many of these were owned and operated by commercial fishing companies and could be heard working fleet vessels throughout the Pacific on their daily CW skeds.

This interesting catch from the North Pacific was the Japanese 'fisheries research vessel' 'M/V FUJI MARU'. She was about 1200 miles NW of her CW contact, JNA in Tokyo.


A Japanese cruise-ship, the 'M/V ORIENT VENUS' was logged early one summer morning while working JNA on 8355 KHz CW. Her position indicates she was in the Mariana Islands.







One of my first catches from the Great Lakes
was the 'M/V Oglebay Norton', a huge bulk
carrier out of Detroit. Her 150W signal was loud and clear late one August evening while in contact with WLC, Rogers City Radio.




The U.S. Coast Guard is still one of the best QSLers around.
Several of their stations will QSL with a nice printed card.
NMC (San Francisco) and NMO (Hawaii) were two
catches, regularly heard on the old 500 KHz calling
frequency.


Stormy weather often provided a good chance
to catch a search and rescue mission in progress.

'Rescue 6008' was an HH-60J helo enroute from
Chesapeake Bay to Elizabeth City, North Carolina during
a midnight rescue operation.




Although not my farthest HF maritime catch,
this was one of the most surprising. 'C4PC'
was heard early one February evening on 8 MHz CW, when conditions seemed terrible. No other ships were heard on the band at the time. As I learned later, the 'M/V MAIROULI' was at anchor near Beirut, Lebanon, a distance of nearly 7,000 miles from Mayne Island.

                                                                .... cont'd

Yesterday's mail brought an official - looking envelope from the U.S. Army! It contained a very nice letter from Fort Huachuca, Arizona, thanking me for participating in the '66th Military-Amateur Crossband Test' as well as three QSL's for the Army-affiliated contacts that I had made back in May.


During the activity, I was able to work Army stations AAZ (AZ), WAR (Pentagon), WUG-2 (TN) ... all on 20m via the crossband mode as the military stations transmitted outside of the band.





In addition to these three, two Navy stations were worked ... NWVC (IN) and NPD (TN) but it appears that 'Army' has beaten 'Navy' ... at least when it comes to QSL'ing!

My recent blog discussing the 49m Canadian stations, discussed the need for a better picture of the CKZU (6160kHz) antenna system. Located on the mudflats of far western Richmond (Steveston) and a stone's throw from the Pacific Ocean's Georgia Strait, CKZU's  gets out very well for its compartively small 500W transmitter.


On a weekend bike ride along the West Richmond dyke, Mark (VA7MM) snapped this wonderful close-up view of the system:

It appears to confirm the rumor that the antenna system consists of a two-wire beam (using wide-spaced folded dipole style elements) ... one element being driven and the other element being a reflector. According to Mark, the orientation would beam the relayed CBU-690 signal up the coast of British Columbia and not towards the SE as the original Google photo appears to indicate. It is certainly a well 'overbuilt' structure. No doubt its height contributes to its ability to radiate a good signal all around North America (and Europe).

So the next time you are tuning around 40m, drop down a bit and see how their signal sounds at your location ... you may be pleasantly surprised.

When initially listening for the station in Calgary, CFVP on 6030, I was never able to detect more than a weak, watery carrier. Conditions must have been much worse than I had suspected as normally this path is an easy one. A few weeks later, when I started looking for them again, I found their 100 watt signal to be quite robust, several days in a row. In the early afternoon, their signal was peaking 5x7 and continued to build until Radio Marti in Florida signed on a few hours before sunset and dominated the frequency for the rest of the night.

An e- mail report to long-time veri-signer and Ontario DX Association mainstay, Harold Sellers, brought a quick e-mail verification. I was hoping that CFVP would still be issuing a paper QSL but nowadays that is getting to be a rarer and rarer policy.


Harold also reports the following details about CFVP:

Next on the the list was Toronto's CFRX, 6070, whose signal has been strong, starting well before local sunset. Veri-signer Steve Canney, VA3SC, requested a written report and an SASE which was quickly rewarded by a rare and very real paper QSL.



Steve reports that CFRX is simulcasting CFRB (1010kHz) using 1000 watts into an omnidirectional vertical antenna. They have received several reports from Europe over the many years that he has been sending verifications.

Now to tackle CKZU!

As indicated in an earlier blog, a planned scan of the 49m band was made a few nights ago ... one at 0400Z (10PM local) and another at 1200Z (5AM local). Both had a decidedly different flavor. Frankly I was surprised at the number of broadcasters and especially the number from Asia, China mainly, heard in the morning scan. One information source I found indicates that most of the strong shortwave signals from China are more designed for jamming than for program content.

My initial impression was that many of the more interesting low power targets from Central / South America and Africa may be a thing of the past but I may be wrong. The 'news' page, of the World Wide DX Club, seems to indicate that there are still lots of juicy targets out there if you are willing to put in the time to look for them, as many seem interested in doing. There also seems to be a larger variety of DX targets available in the higher bands such as 25m and 31m.

For the most part, these broadcasters don't fool around with QRP, and their signals are pretty dominant. Conditions of late have not favored Europe or Africa so there may be more activity from these regions than I think.

The number of broadcasters using remote sites is also surprising. It seems that the relaying of program content for others is big business and for many countries, much cheaper than running their own 250kw stations.

Some links that I have found very useful for identifying SW BC stations:

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!
