Unless i am mistaken, should not the above arrows not be 8N1, and rf
feedback is possable, 25 watts for 10 miles, 25 milliwats would do the
trick, so cut the power and try that also, and if all else fails do the same
as most others have done, ditch minicom and use the kernel based ax25
toghter with a suitable ax25-utils version for you kernel. Check out,
