Shortwave radio history – communications in and out of New Zealand in 1939. This history is rich with adventure and successes that are profound. Our modern communications all stems from this historic work…

This is a short film about the romance of the radiotelegraph service that utilized the high frequency spectrum known as “shortwave” (from 3 MHz up to 30 MHz) as well as the longwave and medium frequency spectrum (below 3 MHz).  This is a short film about communication to and from New Zealand on these shortwaves, using Morse code (eventually, using CW modulation). This film is a 1939 Government film scanned to 2K from a 16mm combined B/W reduction print.

First, I did not work him, unfortunately. But I did hear him on 28038 KHz calling CQ. First I thought it was Japan, no alarm bells were ringing. But when I looked at qrz.com I saw it was Mongolia, so I fired up the rig for transmitting, but then his signal was gone. Yes, that happens on 10 meter band often.

I made a short documentary about a boy who knows a lot about mills. So I followed him with my camera and made this film. The mill is a watermill from 1896. Still on duty to keep our feet dry.

Now my set is tuned on 10m for WSPR.

Results on 10m

It's worthwhile to take a look at the 10 meter band. I did it today. First I worked UP5ØA with CW. Then I heard W3EP with 599 signals. Yes, I worked him and also W1VE with very loud signals.

After all the problems I had with the last theme I decided to just get shot of it and change the site. I’m a big fan of making things simple and so I decided to opt for a theme that was quick to load, looked clean and hand a readable font on multiple devices.

I’d not spent too long looking for themes in the WordPress directory before I came across this one Iconic One by Thematic, so here it is.

Like most of these things you can have the simple version or pay for a better one. I’m not decided but at the very least I’ll buy the developer a coffee

Last night I had a few minutes to operate, so I thought I would call CQ with my 20M Rock Mite. I did a little more than CQ however, as I wanted to know how the radio was getting out. First, I measured the output power. I had assumed 500 mw of output during my first QSO's with the radio but after measuring the output, it was closer to 300 mw. Secondly, I wanted to see where the radio was being heard using the Reverse Beacon Network, www.reversebeacon.net. If you've never played around with this, it is pretty cool. There is an entire network of skimmers out there that will post your frequency and callsign if you are copied calling CQ on CW.

So I called CQ with the beam pointed due north from my Boerne, TX QTH. Withing seconds the RBN spotted me calling CQ on the east coast and shortly thereafter on the west coast. Pretty cool. So clearly I was getting out fine with my 300mw. After a few CQ's, AB4QL, Barry in Alabama, called me.  I swung the beam and he was a solid 559 running his KX-3. He gave me a 329, but he didn't seem to miss anything. The contact was just short of a rag chew but we had nice QSO.

After we signed with each other, I looked up Barry on QRZ.com and learned that his QTH was 820 miles from mine. At 300mw that comes out to 2,733 miles per watt. Any way you slice it, that's good mileage.
