Nice Video on 40 Meter Receiver Project

Tom, AK2B, put up a nice video about a 40 meter receiver that he made from the small circuit boards that Diz sells at PartsAndKits.com. Also, you will see KD1JV's digital dial and the New England QRP club's NEScaf. Nice work guys!

Here is the excellent discussion of bi-directional amps I mentioned. From the web site of W7ZOI:

Here is the mysterious (and perhaps diabolical) Xtaflex from AA1TJ (the first rig EVER to promise "buns of steel.")

The Pontine Islands

We were out on Ponza island this week. Amazing place. Part of the Pontine Island group. Brave Ulysses was an earlier visitor. Roman emperors used it as a summer place. It is only about 33 km from the mainland and you can get there from Anzio in about one hour by fast hydrofoil. We took a small boat over to the beautiful island of Palmarola. I did a bit of shortwave listening. More about this trip in the next SolderSmoke.
