Skipp, Your VHF Syntor is the 40 watt model. The 2511 transistor at Q802 was used only in the HLD4125A power amplifier. According to the Syntor manual 6881043E40 (still available for about $21), the variable-output exciter supplies 1.5 watts maximum drive to the PA. Some components in the PA were range-specific; Range II is 146-150.8 MHz, Range III is 150.8-162 MHz, and Range IV is 162-174 MHz.

Drive level to the 45 watt VHF PA? Re: Syntors at the salvage yard. Drive level to the 45 watt VHF PA? **** Yesterday we made it over to a longtime friend's Government Surplus Buyer/Seller/Dealer location/warehouse. He's got a great deal on LaMarche rack mount battery chargers if anyone is seriously looking for one. In one portion of his facility/building... he scrapped a fair number of VHF Syntor mobiles for the estimated weight value of the aluminum heat sink (metal). A truly sad day for surplus Motorola Syntor radios ... All the circuit boards were removed and sitting in pile so I picked up and purchased (cheap) a fair number of the 45 watt RF PA PC-Boards (still in darn good shape). So... can anyone quickly tell me the drive level? Board has two transistor stages driver M9860 final M2511 reported output power rating 45 watt. thanks skipp skipp025 at yahoo.com
