single chip receiver for fsk my next project is to come up with an if detector module for fast to kb sec packet radio use no fancy modulation scheme just wide fsk for use at or mhz i m a bit familiar with the motorola chip but i wonder if there are newer designs that might work at higher input frequencies my goal is to come up with an inexpensive design for a receiver back end with if input on one end and an fsk demondulator on the other i m particularly interested in ways to use a higher if than do any current chips work up to say mhz with internal downconversion so a normal if filter can be used any suggestions john john r ackermann jr law department ncr corporation dayton ohio john ackermann daytonoh ncr com packet radio ag v n acv oh tcp ip ag v ag v ampr
