Are there any frequency-independent units available for use with customer-<br>
supplied radios? That might open up opportunities for licensed radio amateurs<br>
to use spectrum not available otherwise. This approach was used to solve the<br>
problems on the 11-meter band (CB) with remote control systems.<br>
<br>
I think there is also some unallocated spectrum above 40 Ghz. (or at least<br>
there used to be) which might be useful for very short range systems.</blockquote><div><br></div><div><br></div><div>I'm not aware of any. Also of interest, don't the amateur rules forbid encryption? </div></div>
