Is your reference to "21m" a typo instead of 20m, or are you referring to the 21 MHz band which is 15m. Are you choosing USB for the 20m, 17m, 15m, 12m and 10m bands?. How does the LSB signals on 80m and 40m sound?
The sideband inversion Geoff mentioned is such that on 15m, 12m and 10m, the actual sideband being used is the same as LSB on 80 and 40. The K2 automatically accounts for the inversion, and displays the mode as USB which is correct. 73, Don W3FPR On 1/15/2011 4:04 PM, KA1YMX wrote: > I am sorry I should have mentioned I have the KSB2 SSB board installed.
