Amateur radio at PAR (W4OP)

That's a nice looking 2-B Dale! Please send us the serial number! Even more impressive is Dale's award-wining homebrew solid state version of the 2-B (on the far right). Visit his web site for more info (on his site you can hover your mouse above the pieces of gear for more info).
I'm proud to say that I have a piece of gear in my shack that was built by Dale Parfitt. The story is told in SolderSmoke The Book: I'd built my own version of Doug DeMaw's Barebones Superhet and had liked it a lot. When I saw another one (this one built on a FAR circuits board) for sale on e-bay, I bought it. It stayed on the shelf for a while. Years later when I started working on it, I turned to QRP-L for help and this fellow named Dale Parfitt came to my rescue. It was only after a long series of e-mail exchanges did we realize that the receiver we were discussing had been built (and sold to me) by... Dale Parfitt.

Walford Electronics' "QRP In the Country"
A raffle raised £200 for those suffering in East Africa; the main prize being a year’s subscription to PW kindly donated by Rob G3XFD which was won by Graham G4DPH. George G3RJV was asked to select a couple of displays that ‘appealed’ to him for two other prizes. The GQRP Club had kindly donated a special edition of Drew VK3XU’s latest project book which was also won by G4DPH for his PW Sprat project; a Walford Electronics Radlet CW TCVR kit went to Colin G3YHU for his valved superhet. A years subscription to BYLARA was won by SWL Mike Jones who is about to take his Foundation licence course.
After the event Tim G3PCJ said he was said delighted with the increased attendance and wished to thank everybody whose hard work had made the event so successful. He urged all Clubs within reasonable distance to plan their displays for next year! Watch the press for announcements of the date!

The Dish
We talk about "The Dish" from time to time on SolderSmoke. That's the name of the movie about the role of this antenna in the reception of the TV signals for the Apollo 11 moon landing. This is -- without a doubt -- the best movie ever made about an antenna.
You can get the movie at the Gadgeteer Book Store:

Steve "Snort Rosin" Smith: Silver-Tongued Devil! Dual-band "Vlad the Inhaler" RX
It occurred to me that with the installation of one little switch in the diode part of the circuit, we could turn this into a dual-band RX. Take a look here:
