For those of you that tour with FS II, have you had better luck with 1.9 or 2.4? I have the older 1.9ghz and have found it to be unusable in certain venues. CC recommends 1.9ghz in the USA, and I would think 2.4 would be pretty crowded, so hoping to get some real-world experience advice on what would be the best choice for a new system, being toured in the USA and Canada.
I wish they made a switchable transceiver and Beltpack!
The local university's athletics department has an 8 pack of Hollyland's 1.9GHz units and, from second person reports, they have had good luck with them. This is in a Midwestern city of ~150,000 people. I can report from personal experience that 2.4GHz wireless microphones are nearly unusable here. You have to almost co-locate the receiver with the transmitter to use 2.4GHz systems once the audience shows up.
