I would appreciate very basic advice on "mechanical" aspects like the following: the pre-selector has some molded inductors that can be selected by means of a rotary switch (band selector). Is it advisable to mount the inductors directly on the switch terminals or on a separate (small) PCB? Shorter is better in this case or not?Best regards Daniele With Lambda=2200 m everthing shorter than L/10 (220 m) is "short" :-)Don't worry, 30 cm at 137 kHz is like a low inductance microwave bonding. Mechanical considerations prevail. 73 - Marco IK1ODO |
