The frequency can be set within 1 Hz, but I usually keep the frequency step size to 10Hz, which is more than adequate for CW. amateurradio) submitted 2 years ago * by bennettj1087 AJ2Q [AE] Crystal oscillators improved on the stability of the early transmitters a great deal, but with a crystal, you are, for the most part, stuck on one frequency, which meant you needed a lot of crystals if you wanted to move around the bands. I have used the 40MHz crystal oscillator that is already built in the TR7 as reference for the stabilizer circuit. 95: Electronic Keyer (basic) for OHR 100A, $39. 0-55MHz DDS VFO Signal Generator AD9850 Multiband 5p/6p connect to encoder as per photo. 1
