First. I have the preamp in my MASTRII now and it's still not performing the way it should. I think that I may be having some of the receive issues mentioned on the site maybe wisker growth. What is the best way to determine if the receive side is working to full potential?
Second we now have our IFR 1100S service monitor back. Today I purchased an HP 608E and an HP 608F Signal Generator from a surplus store. Can the regular signal generator be used to tune filters or does it have to be a tracking generator? Is the 8708A Synchronizer that can be added to the 608F anything close to a tracking generator? I also picked up a Micor base of some sort at the surplus store. It is a C73RTB-1106C and looking at the secret decoder ring it looks to be a VHF 100w unit. I need to know if I have all of the pieces of this thing to get it running to see if it's any good. I have the power supply, the receiver, transmitter, and card assembly, but in the pictures I have seen there is some kind of meter on the left side with a speaker and I don't have that. Do I need that for this thing to operate? Thanks, Vern KI4ONW
