Whoever said that is *completely* incorrect and doesn't understand these circuits at all. There are six *official* bands available from Elecraft for the two-band KFL1-2 board: 80m, 40m, 30m, 20m, 18m, 15m, though 160m/12m/10m are certainly possible if you brew it yourself. ANY combination of two is OK. Only on the four-band KFL1-4 board is there a strict limitation to the allowable band combinations to 40m/30m/20m/15m due to the cutoff frequencies of the elliptical low pass filters on the board. But one benefit to the four-band board is that these LPFs are much sharper than the simple filtering on the two-band board. 73, Mike / KK5F _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
