The main thing is to pick a band with stable propagation at the time you're operating, because a slow CW QSO is going to take a little while. > > Whats the reason with the 4 band board doesn't do 80 meters ? > A 4 band board can do 80 meters - but then you can only do 3 bands. A 2 band board switches between two sets of coils and capacitors - so you can choose any two bands. The 4 band design uses the same coils on more than one band by switching in different padder capacitors. But there's a limit on the frequency range. The coils needed for 80 meters are such high inductance that they can't share with 40 meters, and 40 meter coils are too low inductancer to share . All other K1 coils can share with the next-higher band. But the separation between 80 and 40 is too great (percentage separation, not MHz) 73 de Jim, N2EY _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
