Lightwave Article From ‘TCA’


VE7SL Backyard Test
I have recently received permission from Radio Amateurs of Canada (RAC), our national organization similar to the ARRL, to post a copy of an article that I wrote for their bimonthly journal, 'The Canadian Amateur'. I have posted a link to the article on my main web index page..."A West Coast Lightwave Project", which describes the building and operating adventure, shared with Markus, VE7CA. This link will also take you to the page.

Bugs: My New Fascination

As many QRP'ers, I'm a CW enthuisiast. Before I earned my license, CW was an imagined barrier. I imagined how difficult it would be to learn and that it would the ulitmate reason for me failing to get my license. However, for me, after I tried it it came to me relatively easy. I went from 5 wpm to 20 wpm in 11 months as I advanced to Extra Class. As most of us do, I started with a straight key and moved on to paddle and electonic keyer.

During my process of learning code, I had read about, and seen at hamfests, these telegraphy devices called "bugs". Interesting looking contraptions these bugs, but could a person really master one of these things. As I was intimidated by the code initially, so I was intimidated by sending code with a bug. You must understand, of course, that I never attempted to send even a dit with a bug, because I was certain it was difficult.

The past Straight Key Night I was in Santa Fe, NM having a New Years Eve dinner at the QTH of Fred, KT5X, and in the company of John, K1JD. It was assumed by both of these experience bug users that I too was proficient with that instrument. As we retired to the radio shack after a fine dinner with our wives, I was introduced to the bug. I was actually able to send my call after a brief tutorial from Fred, although he forbade me to send actual code over the air after a few of my awkward attempts. but I was able to manipulate the bug. How about that, not as hard as thought. Fred also collects and restores bugs and has a lot of knowledge of the time frame of manufacture and the rarity and nuances of collectible bugs. To get to the point, I was quite enthuisiastic about learning this part of the craft and the history of the bugs was quite interesting to me.

So after a trip (or two) to EBay, I am now the proud owner of a Vibroplex Original from 1944. I've gotten to the point that I'm not afraid to call CQ and have a QSO with the bug. I have, however, been calling all my CQ's to date on my KX3 at 5 watts. I want to keep the damage to my CW reputation to a minimum:-) It's quite fun and leaves you with a sense of accomplishment.



As you see from the picture, the bug is almost as big as the KX3, but its lots of fun. I am now certain that using bugs will always be a part of my CW repertoire. If you don't want to get hooked, don't try it.

One word of advice, find someone to coach you on how to set up the bug. As you can see above, there are lots of knobs to turn to get to that feel that you like.

LIDS_CW

Whilst twittering / tweeting / wasting time on twitter (delete as applicable) I came across a group @lids_cw . This is an informal twitter based group of CW and low impact data mode fans in the UK that seem to have their heads screwed on. The idea behind it is that the group encourages general radio chit chat then suckers you into having a go at CW.

Morse is not something I decided I wanted to do when I started out in radio, Hence the G7 callsign (For those unsure, G7’s in the 1990’s were VHF only because we couldn’t be bothered with CW. Hence the 19th Century rules at the time kept us away from HF as were weren’t proper or some such daftness). But over the years I’ve hankered after at least one QSO in CW. I’m only browsing, for research purposes, I wont be giving up VHF officer!

Sunday at 16:00hrs GMT see’s their net on 40m. I listened in and attempted to decode what was beeping through the speaker an got the occasional character. I cheated a bit and used HRD to decode some more of the text and fill in the gaps. It wasn’t until I let slip on Twitter I was listening in I heard my callsign being called by MW0IAN. Fortunately I had no way of returning the call (otherwise we might still be at it exchanging signal reports now!).

For those of us who struggle with CW but are too scared to admit it, there are others like you. For those of you who had the 5wpm RSGB cassette and never got further than ‘it’,’meant’,’mine’ and ‘nineteen’ but fancy spending hours listening to bleeps but secretly want to have a go. Watch out LIDS  or Less Involved Data Society as it’s known will get you. Keyer at the ready for next Sunday. Snails will be faster.

Celebration of SKCC – K3Y Special Event

Special event, “K3Y,” the Straight Key Century Club’s annual January celebration, commemorates the Straight Key Century Club’s founding in 2006 following the American Radio Relay League’s “Straight Key Night” (SKN). A small group of participants wanted to extend the fun of SKN throughout the year. The Straight Key Century Club (SKCC) is the result.

For the first three years, the club’s founders used the special event callsigns of K1Y, K2A, and K3Y as the celebration’s special-event calls. But, someone cleverly noticed that a ‘3’ is nothing more than a backwards, curvaceous ‘E’. This “KEY” event has operated under the special event callsign of ‘K3Y’, ever since.

The on-air party is open to members and non-members alike. It runs from 0000 UTC Jan. 2 through 2359 UTC Jan. 31. It’s a great time to introduce others to the joys of hand-crafted Morse code using straight keys, bugs, and side swipers.

In this video, you can “sit in” with NW7US, the control operator of the regional activation of special event station, “K3Y/0”, during one of the many shifts during January (2015).

A New ‘VE’ on 630m!

Interest in Canada's newest ham band, 630m, continues to slowly grow. Toby (VE7CNF) in Burnaby, BC, has made his first and second CW contacts on the new band!

Both myself and John (VE7BDQ) had the pleasure of working Toby on 473.000 CW on Thursday afternoon. Here is Toby's description of his station at present:


"I have put together a low-power 630m WSPR transmitter here. I have a USB-TG44A signal generator clocking a phasing-type SSB modulator with WSPR audio coming from a laptop. The modulator gives 45db suppression of the carrier and lower sideband. This drives a ZHL-32A 1-watt linear amplifier. I have a matching transformer and loading coil at the base of my 80-meter inverted-L antenna. Wire height is 10m.

John VE7BDQ has weakly received my WSPR signal. Are you able to receive WSPR?

The antenna series resistance is much higher than I expected, probably due to 10 year old antenna wire and only 4 ground radials. Right now the antenna match is poor and efficiency is very low. I may rewind the matching transformer tomorrow and gain a few dB. Maybe soon I’ll have enough signal to complete a 2-way CW QSO with you.

I have attached pictures of the hardware. After I determine the proper configuration I’ll make a more efficient loading coil."

Toby has indicated that he will soon start construction of a dedicated DDS-based transmitter, with more power to work with. Situated on a normal-sized suburban lot, and base-loading his 80m inverted-L, is proof once again that fancy antennas and a few acres are not needed to have fun on 630m. Toby's initial night WSPR tests were copied by WH2XGP (W7IUV), near Quincy, Washington, at a little over 200 miles (325km) and on the other side of the rugged Cascade Mountains!

Here is a short video of VE7CNF beaconing in QRSS mode before our QSO. The distance between us is approximately 53km (33 miles)...not bad for 1 watt!
 
 
It's great to see new activity. Both VE7PJR (Chuck, near Kamloops) and VE7CA (Markus in North Vancouver) are constructing rigs for the band at present. As well, VE6TA and VA5LF have expressed interest and both have completed crossband QSO's with me on 630m.

As I mentioned to Toby, I'm starting to believe that 630m is a very forgiving band when it comes to both skywave and groundwave as signals have always been much better than I had originally expected. Moving down from 2200m has been the difference between night and day as there is so much more potential for real-time communications on this band compared with 2200m.

Marketing With Morse Code

Code-is-not-dead prognosticators and hand-wringers will be happy to hear Asus is touting a new smartphone camera feature with Morse code.  The smartphone feature has something to do with dual cameras and exceptional zoom capability but unfortunately appears to have no use of Morse code.  But a tip of the hat to Asus marketing folks for using code!

1929 BK QSO Party Fun

 
With headphones clamped to my ears, the past two Saturday nights have been spent in the Bruce Kelley 1929 QSO Party. Before I was hit with the '29-bug, these two weekends were usually taken up with the ARRL 160 CW Contest, and then with the ARRL 10m Contest the following weekend. Perhaps it's just as well that the BK has taken priority as I'm not sure if I could hang-in until 0100 or so anymore for the topband affair....or sit all weekend for the 10m fracas. At least the BK action finishes up early here out west, as by the time 10pm rolls around, most of the guys further east have hit the sack...my kind of contest!

This year's conditions were rather dismal, on both weekends, as...once again...the planet was whacked with more coronal hole streaming. These things are ionospheric-killers from what I can see, as the level of signal absorption shoots way up, and quickly...not as much however, the further you get from the auroral zone.


Not to disappoint, the usual BK winds came up, right on schedule as well, almost coincidental with the start of the Party. Thankfully, weekend number two saw no wind whatsoever....a rare event in December....but, from the sound of many other notes, I wasn't the only one having windy weather.
 
Some of this year's highlights were working my usual "must contact" stations back east....N1BUG (Paul, in Maine), NE1S (Larry, also in Maine), VE3AWA (Lou, in Ontario), K4JYS (Bill, in NC) and WØVLZ (Niel, in MN). It's particularly fun to work Niel as it was the fine Youtube video of his 1929 station that got me started in vintage building.
 
Two newcomers made this affair even better, with the addition of John, VE7BDQ,along with his nice three-band Colpitts and 12-year old Joe, KC9WYV, operating at KBØROB's station in MN. He has a fist as smooth as silk and will be a wonderful asset to our hobby. Kudos to Harold for the "Elmering" of this young ham.
 
I made a very short recording of 40m early on the first weekend, just after the 3PM start.... but there wasn't much to hear at this early hour. On the video below you can see (and hear) the signals of (in order): K4JYS (NC) being answered by KK7UV, W7LNG (OR), WB2AWQ (Reno, NV), VE7BDQ (working WA1JAS in Maine). The 8W signal of WA1JAS is amazing, considering the hour....still daylight here on the west coast.

 
 
My BK log is rather skimpy, considering that it represents two Saturday-nights of activity. In terms of fun, it is very much larger. I rather suspect that this may have been the last outing for my Hull Hartley, as work has now begun on a MOPA rig for next year....hopefully I won't have to worry about the wind weather any longer! 
 
Of particular interest are the rig descriptions and input power levels. I also see Hartley's having a slight-edge over TNT's in terms of usage. It was disappointing to have only 3 contacts on topband, but conditions were just not going to let it happen....maybe next year.

It's really not too early to start building for next year's BK!
