330uH is a pretty big inductor for FM/VHF. RV1 controls RF gain (think of TR1 as two JFETs, one a current source and one a common source amplifier in a small signal model). TUNE VOLTS changes the resonant frequency of the two tank circuits. TR2/TR3 is an impedance buffer. The rest is decoupling.
Looks like a tunable preselector to me rather than a receiver. So part of a receiver yes.
