My First SKCC QSO and 5 Watts to VK Land on 40M

One of the first things I did after completing assembly of my new KK1 straight key (my first straight key in about 15 years) was to apply for membership in the Straight Key Century Club.  There are a number of organizations designed to encourage the use of morse code amongst radio amateurs of which SKCC is one.  As the code is no longer used commercially in the developed world, and we as amateurs are the last large organized group of people to be using it, I think it’s very important that we not only preserve, but also encourage the growth of morse code usage. It is the original digital mode.

There are quite a few folk who claim that morse code is obsolete.  To back up their point of view, they cite facts such as the existence of more recent digital modes, many of which have an even greater SNR (signal to noise ratio) advantage over voice modes than CW does. Add to that the fact that morse code is no longer used commercially* (at least in the developed world) and the argument seems compelling on the surface.

I’m not about to attempt to construct an argument against the newer digital modes.   They each have their advantages and particular uses.  If you need to bounce a signal off the moon (and radio amateurs just get that strong urge to do that sometimes,) then JT65, with it’s ability to copy very weak signals, would be a fine choice.  If you want to ragchew, with it’s slow bit rate, JT65 would be a bad choice (unless you want to ragchew via the moon and have LOTS of time on your hands and the patience of Job).  You’d be much better off with Olivia or PSK-31.  I’ve been playing with WSPR recently and am quite taken with it’s ability with weak signals; I have decoded signals as weak as 30dB below the noise level with it! Truly astounding.

Thing is, just as the more modern digital modes have their specific uses, so does morse code transmitted by CW, which is pretty much the only way we radio amateurs transmit code (unless you’re talking about a repeater identification on FM). What if you’re hiking and camping and want to make contact with a minimum of equipment? Your low power signal won’t go as far if you’re using a voice mode, and all the extra gear necessary to generate and decode digital modes like PSK-31 and Olivia takes extra space. What could be simpler than a small light CW transceiver and a small morse key? It’s this combination of simplicity and effectiveness that makes CW so appealing to me (and to many others.)

I don’t want to seem like an obsessive survivalist type, but the fact that a very simple CW transceiver running on battery power can get a message out to the other side of the globe under the right propagation conditions is reason enough for me to want to keep morse code, and the CW mode of transmission, alive and thriving. Talking about the right propagation conditions, we are experiencing a deep solar minimum right now and even so, my 5 watt signal to a vertical dipole was copied by VK4TJ 11,500 km away on 40 meters last night! That’s a thing of beauty to me, and thank you John for listening for my signal.

Anyway, after signing up for, and receiving my SKCC number, I started listening and calling CQ on the SKCC elmer frequency of 7114 KHz.  No replies, but it was still a little early, and there were no signals on the band.  I came back a few hours later and called CQ a few more times.  Around 11:40pm local time, I heard a loud and very brief dit. It’s the kind of thing I sometimes do if I accidentally touch the key.  I knew that meant there was someone with a strong signal on frequency.  At that point, I can’t remember whether I then called CQ and he came back to me, or whether he called CQ and I replied, but either way, Paul N6EV became my first CW QSO as an SKCC member.  Paul (SKCC #3358) is an SKCC elmer who monitors 7114 on a regular basis and enjoys sending slow CW to help folk like me get some practice in on-air QSO’s. We QSO’ed for a few minutes short of an hour before QSB took us out.

It was my longest CW QSO ever, and the length of it gave me a chance to really get more comfortable. John, VK4TJ,  was also on frequency and commented on the SKCC sked page that he could copy both of us, even when we couldn’t copy each other. Paul and I were only about 560Km apart, wheras John was about 11,500 Km from both of us;  such is the interesting nature of radio propagation.

I stayed up for a couple more hours, heard some scuffling outside, and stepped out onto my first floor balcony to see a group of 5 raccoons staring at me from just a few feet away.

It was a magical night.

5 watts to this Buddipole got me a 559 QSO with N6EV in Southern California on 40 meters.  VK4TJ copied both sides of the QSO.  5 watts and a Buddipole on 40 meters to VK land.  Very exciting!

5 watts to this Buddipole got me a 559 report from N6EV in Southern California on 40 meters. VK4TJ copied both sides of the QSO. 5 watts and a Buddipole on 40 meters and I was copied in VK land. Very exciting! By the way - in this picture, the Buddipole is resonant on 20 meters. When on 30m and 40m it also has a loading coil.

*Ships still use lamps to communicate via morse code when maintaining radio silence.

  1. About two years ago I picked up an AL-80A from a friend of mine who became a silent key. I just got it fired up in the shack and I am not able to get full power out of it. So I want to tap into the knowledge base of those who own one of these.
