MOTOROLA (set of 4) M9860 185 8530 RF Power Transistors

This set of (4) MOTOROLA M9860 185 8530 RF Power Transistors, are new old stock and hard to find at this price.They were used in a Motorola 2 Meter radio and are listed as an RF Microwave Transistor.the M9860 RF Transistor. is equivalent to a MRF 208 NPN 10 W Good for the frequency range of 136 through 174 MHz 12 VDC. The full Motorola Part # 48-869860 Looking at the RF Output of 10 W, I would believe that this device was used as a RF Drive Transistor in a solid state power amplifier.I have only 4 of these listed as a set.
