I changed the VFO frequency range capacitor to 120 pf and now have a 178 khz tuning range. Since I only need 125 khz to reach the SKCC frequency of 7120 khz, I may try a 100 pf capacitor. I would like to know what types of capacitors will work will here. The 68 pf capacitor is a disc ceramic and the 120 pf capacitor is a polystyrene type. To make this change, I not only needed to change the VFO capacitor, but also the 30m xtal and futz around with the turn spacing on the VFO coil to get the proper VFO range. I do not find the 18 khz per revolution tuning rate to be difficult but it is my nature to keep fussing. 73 - Rick - K7MW ----- Original Message ----- From: "Rick Dettinger" <[EMAIL PROTECTED]> To: <elecraft@mailman.qth.net> Sent: Monday, April 03, 2006 10:12 PM Subject: [Elecraft] K1 AGC time constant
