Hi All, I just purchased a Drake SPR-4 and a very nice FS-4 frequency synthesizer. I am going to need the injector cable to go between the FS-4 and the crystal socket input on the SPR-4. Does anyone already have a cable that will work or know where I can find one? I can fab one if I have to, but would prefer to purchase one if it is available. Thanks! GaryAB1GS
