HF frequencies where the limitation does not apply.
The FCC may yet change the rule
for Ham bands, but though it has been under consideration for almost 2 years now, it has not come to pass.
Having said all that, you might find somewhat better/faster connections with one of the new Pactor 4 modems operating in Pactor 3 mode, but it may not be a big improvement or worth the extra money
