Add the 220 Mhz ham-band to

WARNINGAlthough this seems to put out a signal,very little testing has been done. I suspect it puts out spurs in the 440MHz band. I am hoping someone with a "test set" can let us know about the purity (or lack of it) and perhaps give some guidance on any hardware mods to improve the radio. A simple test on 223.580 with a friend with a real 220MHz radio proved that the radio transmits some power. He was able to hear me but I was not able to hear him. He was about 8KMs away. A test with another 220 radio that was much closer worked much better. I was able to talk and hear the other person. A schematic would help. I am guessing that swapping a few capacitors would change the frequency range of the filters and you could pick what bands to support. Enjoy and be careful! de ve3pzr.
