it will be on frequency 72.870[no crystals-1 fixed frequency]

so guys please help me out!!

Ankur - I hope you realize that your question does not make a lot of practical sense   The list of features is exhaustive, you can lookup the details on a few high-end (or even mid-range) radios for the same.  Some of the them can easily be classified as "exotic" (like the Futaba 14MZ which can play music, or announce the name of the model when you select it!).

The question SHOULD be, what are the features that are most needed.  And you can see that discussion here :
