Hopefully somebody can point me to a contruction project, a kit or a source of a VFO. Buying a copy of "Experimental Methods in RF Design" (the successor text to "Solid-State Design for the Radio Amateur") would be a very good place to start reading. These guys have written down a vast amount of very practical information and experience about how to do this sort of thing well and reliably. http://www.bright.net/~kanga/kanga/KK7B/uvfo.htm is a "universal" VFO kit which you might be able to adapt for your needs. Doug Demaw W1FB had another "universal VFO" design in his "QRP Notebook" (a great book if you can find a copy). You can buy a kit for it (board, semiconductors, air-variable cap, copy of the construction article) for $30 from http://www.danscloseoutsandspecialde...closeouts.html I've bought stuff from Dan a couple of times and have always been satisfied with what I've received. -- 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! |
