Here we are at Episode #090, just 10 away from the century mark. Things have been rolling along fairly smoothly, and except for Russ being deathly ill for the last eight days, there’s not even a lot to complain about. In this episode, we have yet another interview. This time it’s with John Hays, K7VE, of Northwest Digital Radio. These guys are producing an entirely new purpose-built radio platform called the UDR56K. This technology promises to be a great advance in the amateur radio arena as well as in the computing arena. It’s a bit of kit that’s going to find a use in almost every radio amateur’s shack. If you want to find out why, please sit down and take a listen to this episode of LHS. We promise you will not be disappointed.

Here’s the finished digital SWR and power meter kit from Radio Kits that is being used by the Workington Amateur Radio Club as a bit of soldering and coil winding practice. Not the poor lining up of the LCD screen. Shame really as the soldering was one of my better bits and that’s going to be covered up. All in all a nice kit to put together, I’m no soldering super star and I took my time so instead of it bring an ‘evening’ kit it I’d more like a ‘weekender’.

Conditions have been good recently on 15m. On that band I have a choice of two antennas – the multiband dipole or the magnetic loop. The multiband dipole doesn’t actually have elements for 15m so on that band I think the 40m element must do the work. The K3 ATU is needed to produce a good match.

There is quite a big difference in performance between the two antennas on 15m. The magnetic loop, surprisingly, has a higher noise level but it also produces stronger signals on some stations. On other stations the dipole seems best. It’s a pity I don’t have a sub-receiver in the K3. It would be interesting to try diversity reception one day.

Whenever a band is open you can usually find some PSK31 activity even if you can’t hear any phone. That was the case yesterday on 15 metres when I worked Nart, JY5IB from Amman, Jordan. That’s an all-time new country for me so I was very pleased to get him into the log. On this occasion it was the magnetic loop that did the job.

I put together this somewhat short presentation on how I use the Elecraft P3 along with my K3 to help me snag contacts. As a matter of fact I believe most pan-adapters will accomplish what I am doing with the P3. Have a look see what you think and I hope it helps out with your hobby endeavors.

Listening to some QSOs on 30 and 40 Meters tonight, I have noticed an increasingly less usage of “DE”.

VERY often, I seem to be hearing (for instance) “W2WK W2LJ” instead of “W2WK DE W2LJ”.

Was “DE” tossed out the window?  Did I not receive the memo?  I know it’s gone by the wayside in contests. Lord knows, the hour and a half it takes to send two letters will really cut down on the ol’ QSO per Hour rate.  But in casual rag chews?

Call me a curmudgeon, call me old fashioned, but I’ll stop using “DE” when I stop using my rotary phone, my 5.5″ floppy disks, my Smith Corona typewriter and stop wearing my spats.

The magazine Practical Wireless is celebrating 80 years of publication this year and has a permit to use the special call GB80PW. I don’t usually make a point of hunting for special callsigns but as a reader of the magazine I particularly wanted to work this one which I knew would be on today it being the publication date of the October issue and the actual 80th anniversary day.

I switched the K3 to 40 metres which I thought the station would be operating on and and began tuning down the band. Lo and behold, GB80PW was the first station I heard, on 7120kHz, coming in at 5 and 7 at the top of the QSB. I switched the magnetic loop from 30m APRS duty over to the K3 so I had a choice of either the loop or the multiband dipole. Switching between the two there was almost nothing to choose between the two antennas but the magnetic loop just seemed to have the advantage by a whisker so that is what I chose to use.

I cranked the power up to 100 watts. After my first call it was clear that Rob had quite a pile-up of people wanting to work him and he couldn’t pick anything out of the pile. For the second call I gave my call twice, once phonetically, and added “… in Cockermouth, Cumbria.” Straight away Rob came back with “the station in Cockermouth, Cumbria.” I thought that would get his attention as the magazine’s technical editor G1TEX comes from here! I went on to have a very nice, if brief, chat with Rob before letting him get back to the pile.
