Re: A silly SSB Question The "tradition" of LSB below 10MHz and USB above 10MHz goes back to the early days of SSB. The early rigs had relatively simple circuitry and an IF of 10.7MHz. Basically these rigs passed the lower sideband below the IF frequency and the upper sideband above the IF frequency. There was no option to choose a particular sideband like there is now. That limitation has become the standard. 60m is different because that mode is legislated by the FCC at the request of NTIA. No LSB, AM, CW or any other mode allowed. -- I support the right to keep and arm bears. |
