The MC2833 is available in a DIP package. Also, there is a receiver chip,
the MC3362, which is almost the same as the '3363, and is available in DIP.
The DIP may be a little easier to deal with than the surface-mount package
(which is the only way the 3363 is available, I believe).

I am collecting parts to build a rig similar to what you describe, but have
not yet started soldering.

Good luck with the project!
