smalljoshua Posted July 6, 2009 Share Posted July 6, 2009 From about half way down this page, it would appear that the frequencies to use are 173.800 MHz174.100 MHz174.500 MHz175.000 MHz Josh Link to comment Share on other sites More sharing options...

Simon Lewis Posted July 8, 2009 Share Posted July 8, 2009 From about half way down this page, it would appear that the frequencies to use are... Although you can still use those old frequencies, new VHF radios are likely to work on: 173·800MHz, 174·000MHz, 174·200MHz, 174·400MHz 174·600MHz 174·800MHz 175·000MHz The old set of frequencies had some potential interference issues. It would be worth contacting the manufacturer to ask which set of VHF frequencies they recommend as being free from intermodulation. Simon Link to comment Share on other sites More sharing options...
Bobbsy Posted July 8, 2009 Share Posted July 8, 2009 The frequencies mentioned by Josh often work but not always, generally depending on the quality of the gear in question. There CAN be interference issues. A single frequency 48 hour license costs £8.50, a full year license for the Channel 69 frequencies is £75. If you rent mics from any reputable company it will come already licensed. Does your client REALLY want to risk his show for an £8.50 license or are you just trying to get away with using what you have rather than renting gear you KNOW will work?

Bob the kit I have is 4 x trantec s3500 and 2 x s4.16 will use both license and license free ch's 170-220MHz & 854-865 when the client asked me to quote for the job I gave the prices included the licence cost aswell but thay were so tight on there budget that 6 mic's @£8.50 x 12 48hr blocks was too much for them - I advised of the issues with licence free interferance ect and thay said it was a risk thay were willing to take. I no the problems and understand that it could trash the production but the client wants to keep it cheep so am only doning what thay want.

Simon Lewis Posted July 10, 2009 Share Posted July 10, 2009 the kit I have is 4 x trantec s3500 and 2 x s4.16 Then you need to contact the helpful people at Trantec and ask what frequencies you should set your six VHF sets to. I suspect that five may be your maximum, but they are the experts... Link to comment Share on other sites More sharing options...
smalljoshua Posted July 10, 2009 Share Posted July 10, 2009 The S4.16 is an UHF set. Josh Link to comment Share on other sites More sharing options...
Simon Lewis Posted July 10, 2009 Share Posted July 10, 2009 The S4.16 is an UHF set. Indeed it is... However, Trantec are still the people to talk to for advice concerning intermod free channels in the VHF spectrum. The key difference from UHF is that the two sets we've discussed above are fixed frequencies. Link to comment Share on other sites More sharing options...
