Can't provide you with datasheets, only some short form specs:
BB109: silicon VHF varactor diode, breakdown voltage 30V, Ctot at 3V
26-32pF, Ctot at 25V 4-6 pF, possible replacement BB139 different case thoughBF311: npn BJT for use in TV-IF applications, ft = 750MHz, TO-92, pin layout B-C-E, potential replacement typ BF199, same case but lower fT (550 MHz).
BF982: dual gate MOSFET for FM/VHF applications, Uds = 20V, Up 5mA, Up < 3.5V
Both dual gate MOSFETs should be replaceable by a BF960 (UHF, 20V, Idss > 2mA, Up < 2.7V)
