I've just been asked to make a cable for a Takstar WGV-601 wireless system ( http://www.amazon.co...M/dp/B006AZDN3A) which seems to be sold by Amazon for about £50, and on Ebay from the Far East.

The spec says that it operates in the 220MHz-270MHz band. Surely this is not legal in the UK?

Hi Dave,
Sorry to be late to the party but you're right - That kit isn't freely usable legally but there seems to be a window of 224.00625 - 224.49375 MHz that could be licensed from OFCOM on a non-interference basis.
The frequency range of that kit clashes with the stuff below (quoted from OFCOM's website):
217.5-230.0 MHz
BROADCASTING


Band allocated to T-DAB.
The band 225-230 MHz agreed for civil use in the NATO band of 225-400 MHz.
PMSE occupies 224.00625-224.49375 MHz on an NIB (non-interference basis) basis.



230.0-328.6 MHz
FIXED
MOBILE
Radiolocation
Radio Astronomy
Mobile Satellite
S5.111, S5.199, S5.254, S5.255, S5.256


Government
Radio Astronomy uses the band 232.0-236.0 MHz at Darnhall, Defford, Jodrell Bank, Knockin, Pickmere, and Wardle. The band 326.5-328.5 MHz is used at Jodrell Bank.
EPIRBs operate on 243.0 MHz.
Mobile Satellite Services operate in the band 312.0-315.0 MHz on a secondary basis.

With the plethora of UHF mics on 863-865 and 2.4Ghz, are the free VHF bands now less crowded with less interference? Is the equipment good enough?

Hi Chienmortbb,

If you can find some good quality gear there's nothing wrong with VHF at all. The only downside is that you can only use 3, possibly 4, frequencies at once in the available RF spectrum.

Thanks Jon. Are we talking old Shure, Sennheiser, Trantec etc rather than the cheap new ones n EBay?
