I'm going to be investigating the extent to which it can be 'pulled' by varying the supply-voltage, also what effect different load-impedances have.

As something that - fitted in a diddy little box along with a PP3 and a 7805 - provides me with a handy and portable way to quickly 'ping' a radio to see if it receives anything and get a guess at the calibration accuracy, this little chip looks like it has great price/performance/pocketability!
