Mike, have you checked the following websites? Lots of good info on the 930! The first topic on this one is "PLL Unlock" http://www.radiomods.co.nz/kenwood/kenwoodts930.html The 17th down here is on the same topic: http://www.ham.dmz.ro/kenwood/ts-930s-w6nl-mods.php (After you click the 17th, scroll down the page. Appears identical to the one above and I suspect most of these came directly from Kenwood as field mods). 73, Bill W4ZV
