Thank you Mike.
I would get the four band module if it had 10m (I might still). I have a PAR end-fed dipole for 40/20/10, so it would be great to use the same antenna for three bands. I have seen that 10m can be done on the K1. I guess that with a wire and ATU I could cover four bands...
Gil.

So the OPF cal must be performed for each band. The result is stored for each BAND in the front panel EEPROM, which allows multiple filter boards for different bands to be swapped in with the previously stored OPF data for each BAND recalled in the front panel board and put into effect when you assign b1 through b2 (or b4) the appropriate ham band.
