You could even use another 2SC2078, if you had money to burn, but more practical components would be TIP41, TIP3055, MJE3055. The module is designed to switch heavy DC loads from a single digital pin of your microcontroller. the tuning circuit consists with c313,q304 when the vco is working as a receiver, when transmitting mode, c 3 1 3 ,q 3 0 4 al-48p multi 4w(2sc2078) sch. All that matters is that it will pass up to 1 Ampere and have the correct base details in a TO220 case.
