scottmcgurk Posted November 4, 2015 Share Posted November 4, 2015 Hey all, I'm looking for a solution to wirelessly transmit an audio timecode to a display company. In the past we've used essentially two radios, one set to permanent transmit and obviously one to receive with the headsets / mic modified to XLR connectors. Has anybody any advice on what radios to use for this - range and reliability are critical so I was thinking motorola, but open to any suggestions you might have!

Dave m Posted November 4, 2015 Share Posted November 4, 2015 what about a professional wireless timecode system? or is that not in budget? Link to comment Share on other sites More sharing options...
henny Posted November 4, 2015 Share Posted November 4, 2015 Are you sending smpte? Or something more resilient that firing systems use such as fsk? For fsk we have hired a Licensed Motorola repeater set to permanent transmit and got a few miles without issue . If you are sending smtpe good luck. For short range I've used Sennheiser iem transmitters with 300 series radio mic receivers on the other end. Link to comment Share on other sites More sharing options...

paulears Posted November 4, 2015 Share Posted November 4, 2015 Duty cycle is important - most commercial PMR is designed for 5% TX, 5% RX and 90% standby. Not many are happy to be on permanent transmit. Hire a proper repeater, they have a 100% duty cycle. Most have different modes available apart from repeat. I've got VHF and UHF Kenwoods and they can have audio applied to the accessory terminal and left transmitting - at 25W or 1W. They will also run from primary power and auto switch to 12V battery backup if you want them to. I'm sure somebody would have similar near to you.

It's done all the time to distribute TC to remote displays on film shoots. Mac Link to comment Share on other sites More sharing options...
scottmcgurk Posted November 16, 2015 Author Share Posted November 16, 2015 Sorry it's taken so long to come back It turns out we're only going about 100m. Line of sight or trees depending on the receiver location. The time code is FSK so at least robust. We're going to use a shure psm900 on the transmit side, ur4d on the receiving - both with a shure paddle which should hopefully see it ok in that configuration Link to comment Share on other sites More sharing options...
lite_lad Posted November 16, 2015 Share Posted November 16, 2015 Timecode buddys are great (depending on the distance you need) they are designed for camera systems but I've used them many times in the events world and they perform perfectly. A big advantage is that they will rebuffer the signal and you can get it to freerun so even if you lose signal mid way through a show you can carry on. http://www.timecodesystems.com/products/wifi-master/ Link to comment Share on other sites More sharing options...
adonex Posted November 28, 2015 Share Posted November 28, 2015 For the pyro in the Commonwealth Games we broadcast time code over a Clear-Com System so there are options to do it over a make shift LAN. You could also use TETRA radio but this is pretty advanced for your average radio user and requires a bit of reading up on as well as a few conversations with OfCom. In this situation UHF/VHF may be your best option. As for most types of radio, Motorola is your friend. Link to comment Share on other sites More sharing options...
