That's what I did is make a 160/80 meter board. Had a ton of fun over the weekend on 160. Managed to work almost 150 QSO's with only 8 hours operating time. Used the K1 and 5 watts out. Worked 38 USA/Canada sections and two DX QSO's. Heard lots of DX but really hammering QRM for this power level! Too bad the band isn't populated most nights! This demonstrates that 160 is VERY viable band that is very neglected the rest of the year!
