However injection locking also works when the frequencies ratios involved are rational numbers. For 22MHz and 10MHz, the corresponding ratio is 11/5 a rational number. For 42MHz and 10MHz, the frequency ratio is 21/5 a rational number Bruce Bruce Griffiths wrote: To generate either 6MHz or 7MHz

To generate either 6MHz or 7MHz from 10MHz one can always use something akin to a conjugate regenerative divider. For 7Mhz this requires a mixer a 7MHz bandpass filter, a 3MHz bandpass filter, a couple of power splitter/combiners, and a couple of amplifiers. For 6Mhz this requires a mixer a 6MHz

Hi Murray and all, Yes, indeed injection locking looks very interesting, and I started reading around. Seems relatively easy for 22 MHz, but not as easy for 42 MHz (good values should be 6 or 7 MHz, right?). So far the practical circuit I've seen are few, and this would make me lean in favour of d
