[McHUG] TX Modules Need Further Inspection

[n3sb at qis.net]

Hi Pat;

The module I got from you appears to be a TX433B. 

These modules are really designed for On-Off Pulse modulation. We've been lucky
so far to get something out of them that can be heard on an FM receiver. It
would be nice to get FM out of one of these. That's one thing that needs to be
looked at further.

Have a safe trip in 8-Land, and Happy Holidays!
