Moving the backbone to 220 coiuld then allow either 2m or UHF for local user access to the backbone. I had wanted 50W rigs for the 10 dB margin, but maybe 5W will do some of the links. <br><br>I have zero experience with 220, so I thought I would ask here.<br><br></div><div>What is the channel we can use on 220 band for 9600 baud packet?<br><br></div><div><br></div>Bob, WB4APR<br></div></div><br>_______________________________________________<br>aprssig mailing list<br><a ymailto="mailto:aprssig@tapr.org" href="mailto:aprssig@tapr.org">aprssig@tapr.org</a><br><a href="http://www.tapr.org/mailman/listinfo/aprssig" target="_blank">http://www.tapr.org/mailman/listinfo/aprssig</a><br><br><br></div> </div> </div> </div></div></body></html>
