Fredrik W Posted July 13, 2018 Report Share Posted July 13, 2018 Hi everyone! I'm coming to Chicago in a couple of weeks from Finland to shoot a documentary and need the lavs to work flawlessly. So, what frequencies are safe, and free, to use? Also if you have any tips I'm open to everything. Thanks in advance! Quote Link to comment Share on other sites More sharing options...
Rick Reineke Posted July 13, 2018 Report Share Posted July 13, 2018 I don't know if "flawless'" will ever happen w/o cables. CHI is a busy RF area. TV channel 16 (482-488 MHz) is allegedly vacant. This may help with selection: http://gothamfaxes.com/ Quote Link to comment Share on other sites More sharing options...
JoshuaT Posted July 13, 2018 Report Share Posted July 13, 2018 I usually use Lectrosonics A1 and block 25 with no problems. Quote Link to comment Share on other sites More sharing options...
Derek H Posted July 13, 2018 Report Share Posted July 13, 2018 How many channels? Quote Link to comment Share on other sites More sharing options...
Fredrik W Posted July 14, 2018 Author Report Share Posted July 14, 2018 Thanks for the replies. I will probably have three channels. Sennheiser G3 or ew100. Quote Link to comment Share on other sites More sharing options...
Derek H Posted July 14, 2018 Report Share Posted July 14, 2018 You’ll be fine. G3s have a wide tuning range and I’m sure you’ll be able to find 3 clean freqs. If you need need any help while you’re in town get in touch with Gerry at Second City Sound. http://www.secondcitysound.com/ Quote Link to comment Share on other sites More sharing options...
Rick Reineke Posted July 14, 2018 Report Share Posted July 14, 2018 If you do not have an external scanner (the G series Rx scanner is not very sensitive), going to the Sennheiser USA Frequency Finder is a good place to start. Try to find a TV channel with -80dBm or less signal strength and use one of the channel bank presets in that range. For instance, from what I basically see in Chicagoland for a Sennheiser G 100 series frequency block A, a bank with presets within 530-536 MHz would be a 1st choice. Do a walk test at each location to confirm no interference (and pray to the RF gods). Quote Link to comment Share on other sites More sharing options...
Derek H Posted July 14, 2018 Report Share Posted July 14, 2018 Also when you scan on a G3 set your squelch to low to find the cleanest channels. Quote Link to comment Share on other sites More sharing options...
