[TenTec] 1208 Transverter

[Stuart Rohre]

David,
The 1N4007 die is much larger and more rugged than the ordinary silicon 
diode die of the 1N4148.  It has been shown to work in other RF 
switching circuits, and they are very low cost, since they are a 
ubiquitous power diode.

You also could probably order the correct PIN diodes from Mouser, who 
have no minimum order. (But, I like to add a few items to make the order 
worthwhile to them.)
