V mount battery test

Earlier this year I decided to compare some of the V-mount batteries available and see what the differences were. Some of it was rather eye opening, and since then I’ve expanded on the original article and have now created a dedicated page for batteries - listing all their specs, including crucially, their relative capacities versus their size and weight.

Wireless microphones and monitors
11 May 2015
Wireless microphones and in-ear monitors in the UK are generally available at VHF (170 - 210 MHz) and UHF (470 - 790 MHz).

There are three ways in which you can legally use them:

Licence-exempt
The ranges 173.8 - 175 MHz and 863 - 865 MHz and 2400 - 2483.5 MHz can be used without a Licence subject to the requirements of The Wireless Telegraphy (Exemption) (Amendment) Regulations 2006. These ranges are also used by other low power equipment so can be subject to interference.
