An e-mail exchange on QRP-L this morning about using ceramic resonators in 455 kHz filter circuits (great idea Grayson!) led me to the ham radio corner of the PAR electronics web site. PAR is the company run by Dale Parfitt, 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.
