Approaching Ely - NOT amateur radio


Yesterday we got the train back to Ely. This was the view through the train window showing the cathedral and boats. 

Ely is a surprisingly busy station where many lines meet. It is rare to not see something going on there.

Fredbox in Eire

Recently, I was asked permission to reproduce the Fredbox in a PDF magazine in Eire. It was nice to be asked and, of course, I said yes. It is now available.

Geosynchronous Oscar 100


It is some weeks since I last peeked at the narrowband transponder of this satellite. Activity remains very low when I last looked on a Friday afternoon in Europe. Overall, my recommendation is still "don't bother".

Gloucester cathedral glass - NOT amateur radio

Earlier this week, we stayed in Gloucester and visited the cathedral. It has some of the finest medieval glass in the UK, and probably the world. Some examples are here. 

The bottom right is from the great east window which was erected in 1350 whilst the others are in the cloisters.

How simple can you make a transceiver?

Many years ago, I built the XBM80-2 80m CW transceiver. It never got cased, but shows how simple a transceiver can be! Somewhere recently I was told that it is a good idea to keep DC from hitting the crystal earpiece. If this is the case, it is probably worth adding a DC blocking capacitor between the audio transistor and earpiece. I have no idea if this is an old wive's tale or fact.
