Gil, You cannot do both 20 meters and 10 meters on the 4 band board. The Low pass filter for the 2 higher frequency bands is shared, so if the LPF were to pass 10 meters, the 2nd harmonic of 20 meters would not be suppressed.
If you use the 2 band board, the Low Pass Filter is dedicated to a single band, so that shared problem does not occur. The 2nd problem with 10 meters on the K1 is finding a fundamental mode crystal that will operate at 36 MHz. 73, Don W3FPR On 6/16/2012 8:26 AM, Gil G. wrote: > Thank you Mike. > > I would get the four band module if it had 10m (I might still).
