I really enjoy CW, it's my preferred mode. However, it's not just the mode I enjoy, but the different tools of the trade. There are paddles, straight keys, bugs and the variations on the those themes, single lever, double lever, and then iterations within iterations of key and paddle design. Well, I enjoy all of them. I collect keys, paddles and bugs, but not just to look at, I love getting them on the air. I have a K3 which allows me to connect a straight key or bug into one plug and a paddle into another which allows me to switch seamlessly between a paddle and a bug or straight key. However, I wanted to have a straight key, maybe a couple of bugs, and paddle ready to go on demand and in addition a WinKeyer that interfaces with my contesting software that has to be plugged into the radio also. I needed a more efficient method of changing between the keys rather than  leaning over reaching down among the tangle of wires and cable, feeling for the plug before I could make the change.

I needed a switch, one that would allow me to select the key or paddle that I wanted to use. So I begin looking for a switch to suit my needs among ham equipment suppliers, but found nothing. I finally found a couple of schematics on the web to build my own and decided to take that path.

I was about to start ordering the parts when a friend of mine was visiting the shack. I told him about building the switch and his response was; "why do you want to that, you can a switch on EBay that will be relatively cheap and do the job". He told me I wasn't Googling with the right words. He suggested I try "3.5mm audio switch ". Who knew? Much to my surprise and delight several devices came up that would meet my needs. Here is the link to the one I bought.

A cable with an 1/8" on one end (switchbox) and a 1/4" connector on the other, (K3 plug)  works for the K3. Simply connect the switch via the cable to the radio and then plug in your keys, paddle, etc. into the switch. As can be seen below I have a straight key, bug and Winkeyer plugged into the switch, while the paddle is plugged directly into the radio. I actually have an empty port in the switch where I usually have a second bug plugged in. You could actually get a second switch that would allow multiple paddles to be at your disposal as well.

So when I'm chatting with my CW buddies I can change my method of sending code with the push of a button. I can answer a CQ'er with a like kind instrument. An operator calling CQ with a bug, I can answer with a bug, etc.. This switching solution is very easy and very economical. There are 8 position switches available as well.

This Saturday as well as the next will be the annual Bruce Kelley 1929 QSO Party, otherwise known as the '1929 BK'.





It's the once a year opportunity to celebrate the sounds of early amateur radio ... only transmitters that are 'era-appropriate' are allowed to be used. More specifically, transmitters must employ tubes that were available in 1929 or earlier, and transmitters must be self-excited. No crystals allowed! Crystals were new and largely unaffordable for most hams back in the depression days.

1929 marked a real turning point in amateur radio as governments finally cracked-down on things such as frequency stability, out of band operations and re-alignment of call districts. In short, hams were henceforth required to behave themselves and to clean up their signals and methods of operation.

Although the new rules did a lot to improve things when it came to 'signal purity', there was still a long way to go ... but the wheels of improvement had been officially set in motion and the next decade would see monumental changes in both transmitter and receiver architecture, as engineers along with some particularly gifted amateurs, strove to unlock the challenges of this relatively new technology.

If you tune across the CW bands during the next two Saturday nights, you will have the rare opportunity to hear exactly what the bands must have sounded like back in the early '30s'.

For the most part you will hear single tube Hartley, Colpitts or TNT oscillators with a few two-tube MOPAs' thrown in. Many of them will suffer the same problems encountered by the boys of '29 ... chirp, drift, buzzy notes and frequency instability from antennas swaying in the wind. The MOPAs' will sound much better but some surprisingly nice-sounding signals can be heard coming from properly tuned and optimised single-tube oscillators. I recall being blown away by the lovely sounding signal I heard from such a rig when first tuning into the BK activity several years ago, only to learn that it was a self-excited Hartley using 1/4" copper tubing for the oscillator tank circuit!

The '29 watering-hole on 80m will be around 3550-3580 kilocycles (be careful not to confuse this with kilohertz!) while the early afternoon to sunset 40m activity will be found from 7100-7125 kc. There may even be a few on the very low end of 160m, later on the first Saturday night only. Although many of these transmitter styles were used on 20m and higher, BK rule-makers have wisely decided not to inflict these sounds on the present populace as it would likely keep the 'Official Observer' guys busy for several days writing pink-slips.

Heck, there me even be time to throw something together for the following Saturday if you have a few parts and an older tube or two ... the '27 comes to mind and is readily found in many junk boxes. Maybe you know an old timer with 'lots of stuff' that could help out.

Unfortunately due to a number of coinciding events, I'll not be on-the-air for the event this year, the first one I've missed since getting in on the fun several years ago.

This weekend's ARRL 160m CW was a ton of fun.

Conditions were unusually good, which always makes things more interesting.




I ended up with 412 contacts in 78 out of 83 ARRL sections. If I was attempting a WAS on Topband, I would have made it to 48, missing just Nebraska and Rhode Island. Oddly enough, RI was my 50th state when I completed my original 160m WAS, back in 1984, which was certificate #225.

That was done from my tiny 33' wide suburban lot, using the same antenna that I have now, a half-sloper. My radials were strung around all four edges of the property line and just lay on the ground or were stapled to the fenceposts. The power came from a pair of 6146's and was just a little less than I used in the contest this weekend as I entered in the Low Power (150W) category ... however, back then it took me several winters to finish my Topband WAS as there was a lot less activity than there is nowadays it seems. The only other sections missed during the contest were Puerto Rico, Newfoundland and North New York.

With a fairly dormant Sun and the 'almost-quiet' geomagnetic conditions of late, good propagation continued into the week ... in fact, Sunday night was the best I have ever observed on 630m!

Such stable conditions here on the west coast always favor the east-west and polar paths and Sunday proved that in spades. Overall, 53 different stations reported reception of my 630m signal, more than any previous overnight period.

The highlight however, was the reception of my signal in Europe, with five decodes from LA2XPA on Kalvoya  Island off the southwest coast of Norway. Rolf has an exceptional location and nice beverage antennas so most of the heavy-lifting was being done on his end. However, without the co-operation of the propagation gods, none of this would be possible. To make things even better, John, VE7BDQ, also made it across to Norway as his small station continues to perform amazingly well. As I mentioned in an e-mail earlier today, his is the textbook example of what can be done on 630m with a small suburban backyard, some homebrewing skills and a small antenna system.

The WSPRnet map shown here illustrates just how many folks are tuning in every night to this part of the spectrum ... with many getting instantly hooked. Hopefully this great propagation is just a small taste of what lies ahead for us over the next several years of low solar activity.

Recent mail has brought two nice surprises. As I am preparing for this weekend's ARRL 160m CW affair, a certificate from the ARRL arrived ... from last year's 160m CW Contest!






It seemed that I had somehow stumbled into top score from VE7 land for the single-op, low power division and since I haven't seen a QST in decades, this came as a complete surprise.


Over the years I've always tried to test the 160m waters at contest time just in case conditions are amazingly good ... which they haven't particularly been for the past few years of solar angst. Even piddly Cycle 24, for most of its lifespan, has proven powerful enough to mess up the Topband.

The 160 contest I enjoy the most is the December Stew Perry. It's the only one that's scored fairly and QSO points are determined by distance. Compared to working something close, any of the east coast grids from out west will get you a sack-load of points ... anything off continent earns you a boat-load. My strategy in the Stew has always been to 'search & pounce' the FN and FM grids for their high value point reward. If I had more late-night staying power in any of these affairs I could probably do a better job but I've found my fondness for the warm fleece-sheeted bed beckoning earlier each year. I'm sure it has nothing to do with getting older ... right?

I honestly don't know how some guys, much older than myself, can hang in there 'til dawn. Maybe it's coffee, which would certainly do it for me. If I even look at a coffee after the noon hour, I'm still counting sheep past midnight. A late night contest-coffee for me would guarantee no sleep until the following night unfortunately.

The second surprise was a nice QSL from Mark, WA9ETW in Wisconsin, confirming our recent crossband QSO ... 630m to 80m CW. Notice Mark's receiving antenna used on 630m, just a 100' wire about 15' off the ground! It doesn't take much to hear domestic signals on 630m so if you already have the WSPR software installed and are familiar with its operation, why not set your receiver to 474.200 in USB mode and see what you can hear. There are stations from coast to coast beaconing every night on this band. Be sure to set your software to upload your decodes to the WSPRnet site so that everyone, especially the beacon operators, can see who you are hearing.

If we worked in the recent 630m crossband event and you'd like a card, please let me know ... I'll be happy to put one in the mail for you.



How I do wish that the FCC would get on with it and legalize the 630m band in the U.S.A. Hopefully the turnovers in Washington will not translate into further delays as is often the case when big governmental changes are in the works. In the meantime, hopefully we can at least work each other in the ARRL CW 160 this weekend!

As usual, the wonderful LF and MF conditions experienced during the week went into the dumper as the CLE weekend arrived.




Looking back, most of this can be blamed on our monthly (~28 days) repetitive schedule which nicely matches the rotation of the Sun. It seems that the same large coronal hole stream that whacked us during CLE 212, is the same one that showed up for CLE 213 right on schedule. Perhaps we need to shift our schedule by a week in case it wants to hang around for yet another rotation.

Conditions were not as bleak as I make them sound but they were a far cry from those enjoyed earlier in the week. The skip seemed fairly long on all three nights, but most signals were on the runty side, with only a few making strong appearances here on the left coast.

As shown below, conditions were quite 'flat' for the entire weekend and propagation did not vary much in quality other than favoring slightly different regions each night. Interestingly, 'YLH - 247' in Landsdowne House, Ontario, whose antenna was pictured on my last blog, was not heard at all on both Friday or Saturday but had a booming signal on Sunday night.

         Date 27 27 27 27 27 28 28 28 28 28 28 28 28 29
         UTC 0900 1200 1500 1800 2100 0000 0300 0600
         SFlx 81 81 81 81 83 83 83 83 83 83 83 83 85 85

         K-in 3 3 2 1 2 2 2 2 2 1 2 3 2 3

My usual procedure with the Perseus SDR is to record the CLE segments of the band for two minutes, every hour and every half-hour, from shortly after sunset to local sunrise. It then requires several hours of carefully going through the recordings to see what CLE signals were recorded ... sometimes spending up to an hour on one frequency only, sorting out what was coming through.

I have also found that the classic blue-screen waterfall does not yield the best contrast for finding weak signals ... the 'photo-negative' screen shown above is far superior, with signals in black appearing on a white background.
