On the chance that someone here can give me some hints, I'll put out a description of a project that I'm working on.
I want to provide the ICOM bandselect voltage derived from the band select outputs on the K3. I can easily do it the last century way, using a 4067 CMOS mux (a 24 pin DIP package), and a bunch of resistors (and that's in progress). But a more modern way would be to use a 8-pin PIC and an op amp to integrate and amplify a PWM output (two 8 pin packs and a just a couple of resistors). I think. But I'd like some pointers to information on doing the latter. Any hints? Good sources of information? 73, doug _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
