I'm very glad that my little "hint and/or kink" re. the EICO 717 keyer touched an appreciative nerve with you! In answer to your question, it is THE GLASS BODY OF THE REED RELAY ITSELF that protrudes 1/4" (or so) from the rear of the field coil. You need to ascertain that you even have the same problem that I had in the first place---and in this regard, you will must key a rig / external audio oscillator to accomplish this. DO NOT rely upon the keying characteristics of the audio oscillator internal to the 717 itself in your critique---it is NOT driven by the filed coil / reed relay assembly... Jim, you would not BELIEVE the trouble-shooting gymnastics that I put myself through, before realizing that the "fix" was so simple! I swapped tubes, I RFI-proofed the power leads / keying leads entering & exiting the 717, AD NAUSEAM...and all for the simple sake of moving one small relay... "The best laid plans of mice & men"...or, As William Shakespeare would say, "...T'was ever thus!" Hi Hi Oh well, at least it's fixed---and maybe my headache here will prevent another one out there in cyberspace somewhere...! ~73~ de Eddy VE3CUI - VE3XZ
