Unfortunately the same way some of my brit friends found themselves in catch 22 regarding bio-fuels.... was not illegal. But was not taxed, so could not be used without paying tax. But there was no agency to pay tax to. IE: Bureaucracy! Big fines, court appearances, no law broken, yet all tangled up. I'll just say the US is not the only country with agencies restricting things based on red-tape rather than any legit reason. Even the FCC can be worked with if you go to the trouble to find the entry point, I've seen it done before more than once. But that's harder than having arm-chair lawyers make their declaration "It's illegal". :-) My read: If the radio stays on a single frequency in SSB mode the new mode does not meet the definition of spread spectrum that is restricted in HF. Many advanced digital protocols manage the spectrum in the SSB bandwidth to achieve performance. But since the implied carrier frequency is not moving, it's not spread spectrum in the classic sense. You might be able to argue if it's legal for use in certain band segments, etc. You could talk about effective symbol rate, though many modes are working around that as well. Have fun, Alan km4ba
