Radio Mic Frequencies

[scottbramall]

Hi,

Just found this on ebay and was wondering if it can be used without a lisence? It states about TV frequencies. does this mean a normal TV would pick it up?

 

Any help appreciated

Thanks

Scott

The frequencies listed would very definitely require a licence in the UK...and the availability of such a licence would depend on your location since you could easily cause interference on commonly used TV channels.

 

If you had an old-fashioned TV receiver that would let you manually tune through frequencies you might be able to pick up something from the mic, but it's unlikely this would work on a more modern TV since most now now have synthesised frequencies for each channel with a fixed offset for the audio subcarrier.

 

If used regularly, you could spend more on licencing that you did on the mic system...if you could get a licence at all.

Ok, Thanks

 

Any idea of how much a lisence would cost?

It's in both the Wiki and the FAQ, but for radio mic licences, go to http://www.jfmg.co.uk .

Neither of the two bands this is specified for are what you would typically think of as radio mic allocations in the UK, normally 863-864Mhz sort or region, plus or minus a few depending on what sort of licensing you have gone for.

 

Licensing info here for radio used in programme making and entertainment.

 

You would do better to buy something license exempt the UK, rather then a grey import which if licenseable at all will cost real money to license and will be licensed on a fixed site basis.

Academic question now, as it's been taken off auction....

Er, not exactly, dmills.

 

The frequencies you mention are the licence exempt UHF ones, but it is easy and relatively cheap to licence all of Channel 69 (roughtly 854.9-864). You can get 2 or 3 channels in the licence exempt space, but a licence for up to 14 channels (or less depending on the quality of your gear) on the whole channel is about £75 per year.

 

However, it's wrong to say that the frequencies of the AT units on Ebay aren't normally licenceable. The whole 470-854 range is available for inband licencing, done on a job by job and location by location basis. That's how big shows get 20-40+ channels at once.

 

I agree that in this case, the exempt or shared frequencies in or around Channel 69 make far more sense though.

 

And, for the OP, the cost of the licence for your grey import will depend on whether you want multiple sites or a fixed site. Basically, for a single channel, it's £8 per 48 hours but there's a break clause if you stay in one place for a length of time.

Granted I was simplifying a little, I figured that someone is that market was unlikely to be using dozens of channels, and was very likely mobile which would make site licensing prohibitive.

As far as I'm aware, all radio transmitters still need an approval number - used to be MPT1350, but I think that may be out of date now, but even with a licence, you still need type approved equipment.

Not sure, think you can still use 1350 but newer stuff is marked 1351, might be wrong or just forgetful!
