DeafDave Posted June 22, 2013 Report Share Posted June 22, 2013 Hi With a choice of buying a Sennheiser coms which can only be used as coms or getting the Sony utx -b2 transmitter receiver set for the same price and using it in reverse I thought Id try the Sony set because it has a dedicated headphone output on the receiver with volume control. With all transmitters off I can scan using my Lectrosonics dual receiver and it will show all frequencies to be clear for use. But if I turn on my Sony transmitter and rescan it shows all of Channel 38 - 606 to be used!!! Ive even tried tuning the Sony transmitter to the upper end of Ch38 and its still affecting the lower end too at 606 I think the 2 units I have are faulty but Im wondering if anyone else uses these Sonys as coms and has the transmitters in the bag without getting the interference? The Sennheisers dont seem to do this when their transmitter is in the bag but you cant really use them in revers for coms as they dont have a headphone out and you cant get enough volume out of them for headphone use. Thanks for any feedback or thoughts! Quote Link to comment Share on other sites More sharing options...
DeafDave Posted June 22, 2013 Author Report Share Posted June 22, 2013 These are the suspects, but in the Channel 38 606 version http://www.bhphotovideo.com/c/product/553684-REG/Sony_UWP_V1_4244_UWP_V1_Wireless_Lavalier_Microphone.html Quote Link to comment Share on other sites More sharing options...
jason porter Posted June 22, 2013 Report Share Posted June 22, 2013 move the transmitter away from the Lectro receiver, does that help? SRa or SRb? Quote Link to comment Share on other sites More sharing options...
DeafDave Posted June 22, 2013 Author Report Share Posted June 22, 2013 Its the SRB Lectro receiver They are at opposite ends of a sound bag so cant be further away than that! I think its more to do with a problem with how focused the transmission frequency of the Sony is and also the power output of the Sony which I thought was around the same as the Sennheiser g3s which are 30mW Quote Link to comment Share on other sites More sharing options...
jason porter Posted June 22, 2013 Report Share Posted June 22, 2013 My Zaxcom does the same thing, the filtered antenna pretty much eliminates it. Some people put the offending transmitter on their belt to get it as far away as possible from the receiver. How much frequency separation between the 2 devices?
