wrote: You need a stiffer driver than 2222. Common CB finals 2sc1971, 1909, 799 and other are all good for that power level and easily run to 30mhz (some to 6m!). FWIW, the Elecraft K2 uses a single 2SC2166 as a driver, feeding a push-pull pair of 2SC1969s. -- Dave Platt AE6EO Hosting the Jade Warrior home page: http://www.radagast.org/jade-warrior I do _not_ wish to receive unsolicited commercial email, and I will boycott any company which has the gall to send me such ads! |
