as mentioned in another thread my UHF mics wouldn't work last night, i'm sure i read somewhere that certain radio mics would be useless soon as the frequencys were being withdrawn and used for something else ? ive tried the search facility but can't find the topic, can anyone enlighten me ? as i plan on buying another set this week, once ive established whats wrong with mine.

No the frequencies are not yet withdrawn and my uhf mics are working fine. I should check your mics.

No. If you are using 4 or less UHF transmitters and don't currently have a JFMG licence, you are (should be) operating in channel 70, which is unaffected* by the change.

* apart from the likelihood of ch.70 traffic becoming heavier as those with kit that currently operates in the neighbouring licenced channels 67-69 only (that won't work in ch.38) being operated post-switchover in deregulated ch.70 bandwidth.

good info

and post script, ive been into the garage and the fault is with the 1/4 jack input on the mic control box, if i pull the lead out a tiny bit the mics work fine.

You can't 'withdraw' a frequency, it'll always be there (Laws of Physics ;) ) and any transmitter and receiver tuned to the same will respond to each other.
You can however make it illegal to operate on certain frequencies without a licence, and in the extreme operate 'jammers' to prevent their use, although they would need to be extremely sophisticated amd powerful to eliminate the short distances over which radio mics are normally used. :)

what channel/s are you currently operating in?
I think it 830 - 860?

I discovered that in 1983.

One minute my radio show was going out for up to 30 miles across the South East, then the police & DTI turned up, took us off the air & carted us off to the local nick!

The Channel 70 deregulated licence free bandwidth is 863.1 to 864.9, if you are operating in the channels below this, you should have a JFMG licence.

If you operate in these channels without one you risk a fine, equipment confiscation and public flogging.
