I know some of the FCC frequencies are illegal after the switch to digital broadcast. I was wondering if 626-662 Mhz range is legal or not.
Also what is A, B and C frequency (in MHz). Thanks for any info

For sennheiser, C is no good, and should be pulled from legit sources. A, B, and G are all good choices, depending on your area. Use the link in Chris' post to find the most open band of the three. I have found most places I've been to after the transition have a lot less congestion now that the analogs are dark. Not having two of every station is nice for a change. :-)
