Add radio and transponder to Vertigo Studios PT17 Stearman

Hello Everyone,

Is there a way (or procedure) to add a radio and transponder to an aircraft.

(Pop up is fine).   

You may say, it sounds silly to add a radio and transponder to a Stearman.

But, I sat in one (Stearman) yesterday and owner has transponder and

radio installed.

Would love to add these, so I can practice VFR communication with VoxATC 6

while flying Vertigos Stearman.

Thanks,

B.
