Re: [Elecraft] KSYN3A

Re: [Elecraft] KSYN3A tuning noise on 40m

The K3 has very high dynamic range, requiring a high-level local oscillator (the synth). One way to minimize spurs ("birdies") in a superhet design of this type is to include very narrow-band filtering, which we used throughout the radio. The ham-band filters are all just a bit wider than the ha
