KH1 v KX2 for portable use

In the UK, Elecraft radios are very expensive. I don't think that is the case in the USA. Also, I do not think the KH1 is available outside of the USA. 

K4SWL has done a video comparing these radios. Elecraft make some good products, but I wish they were less expensive. The conclusion is it depends on how you intend to use the product. 

One thing it does do is tell us just how effective a small HF handheld can be if used with a whip, counterpoise and ATU.

Doctor reveals what you'll see when you die - according to science - NOT amateur radio

 This video was see on YouTube earlier. I had a cardiac arrest in 2013. Many with a religious faith will expect some kind of life after death.

Amateur radio in the 1950s


After WW2 many people used surplus military equipment as this was plentiful . These were the days when many built their own gear and there were no Japanese transceivers. Most people used AM.

23cm beacons

My nearest 23cm beacon is (I think) GB3DUN (66km) on Dunstable Downs. 

From home in the shack I can only use a 6ele PCB antenna firing out of the shack window. With the leaves off the trees, now is probably a good time to see if I can receive it.

It is very much an obstructed path.

This is a useful distance and bearing calculator if you know the Maidenhead 6 figure grid for both the TX and RX. See https://www.chris.org/cgi-bin/showdis .

Chocolate box village - NOT amateur radio

This is the village of Dalham not far from us. It is filled with "chocolate box" thatched cottages that must be worth a fortune today.  

At one time they were probably worker's hovels. How times change.

Wet string antennas


Yesterday I mentioned using the coax to my 2m big-wheel antenna on 80m. It worked remarkably well. 

I came across this video on YouTube showing someone using a coat hanger antenna on 10m. As long as the antenna is properly matched to the rig with an ATU, you may be surprised.

If you do not have an antenna for a certain band do not give up. I am sure such compromise antennas would be down on a "proper" antenna, but do not be too surprised if it works quite effectively.

Some have used wires in their plastic guttering down-pipe or a flagpole. You may be amazed just how well such hidden antennas work.
