Congratulations to LRS member Brian Flynn whose article "A Versatile PLL PC Board Design - for Applications from HF to Microwaves" is published in the opening issue of the new RSGB publication RadCom.plus. This is available online only, and only to RSGB members. (There's a moral there somewhere)!
Brian's circuit provides accurate, stable frequency sources in the frequency range from a few MHz to 4GHz, depending on programming and components used, with a power output of around +10dBm.
