On our way to Caserta today we visited the abbey at Monte Cassino. This was totally destroyed in WW2 as it was believed to be occupied by Nazi forces blocking the allied assault on Rome and Northern Italy. It is perched high up above the town of Cassino. It was very old and totally rebuilt after the war ended. It took 20 years of rebuilding. 50000 people died before the allied forces took it in 1944. It occupies a very strategic point.

Geosynchronous amateur satellite?
As you know, we are entering a period which could last very many years when the higher HF bands will not be good for F layer DX. OK, we will have Es to liven things up, but much of the time bands like 10m will seem "dead".
To the rescue (if successful and this is a big "if") could come amateur geosynchronous satellites using linear transponders at microwaves. One such is a Qatar satellite that may be launched next year. I say "maybe" as the launch has already been delayed. Geosynchronous satellites stay in the same place, so antennas can be fixed.
A 2.4GHz uplink and 10GHz downlink is quite an investment, but could be worth it if the satellite is a success.

Colosseum, Rome - NOT amateur radio
Another shot from Rome yesterday - this time the famous Colosseum. This is an amazing place. As I said yesterday, Rome was very busy.

Rome, Italy - NOT amateur radio
Today, we visited Rome, Italy. We were last there in 1974. We saw most of the main sites, but all were very crowded and heavily guarded by armed police and troops. It is still a fine city though.

Anagni, Italy - NOT amateur radio
Local cheese and coldmeats |
It was market day so there were stalls a various places along the main medieval street. It had a nice atmosphere: local out enjoying the market.
We also had a decent coffee for just 1 euro each.
15m Pipit QRP Rig
Some years ago my only rig in use was my homebrew QRP transceiver on 15m. With just a low wire dipole and 800mW I worked lots and lots. Sadly, it got dismantled so I could use the case for another project.
