Hi Clark,

Do you have any info on the Ten Tec Power Miter series  
transceivers??  such as schematics and modifications, Have two of  
them (PM-2B's) and they are totally different layouts, Boards, quite  
interesting at best, some bozo get into it and changed a pot load of  
parts, which drove me nuts for a while. Any suggestions?
