Why Channel 38 - well its all thanks to the DSO (The Digital Switchover)which takes place in 2012 (after the Olympics) and will have a major effect on users. Most notably, we will lose the use of Channel 69. All equipment tuned to this band will become unusable (you can try and use it if you like, but the signal will be totally swamped by digital TV so you'll be unlikely to get anything but interference. Channel 70 is De regulated and License free so the entire space between 863.1 - 864.9 MHz is free. However this bandwidth is very narrow and at best you will get 3 to 4 mics to work on channel 70. Any more than this and the mics will over lap each other and interfere with each other. So if your looking to use 4 or more radio systems at once then you do need to move to the wider bandwidth on Channel 38.
