Fred Salles Posted October 19, 2018 Report Share Posted October 19, 2018 Hello, I have a problem with one of a set of 2 Lectrosonics SMDB transmitters: the antenna seems to have a sensitivity problem. As soon as something touches it (finger, cable, bag...) it releases a wave like kind of noise in the signal otherwise clean. The other one smdb does not have this problem. if the transmitter is put still on a table the signal is clean, even when approaching the hand. Receiver is a dual, SRA5P. What I did so far: -scanned and changed freqs -swaped freq between the 2 smdb -swaped antennas -tried different mike capsules (don't know their wiring though but all worked) -changed batteries none of the above changed the situation. Holding the base of the antenna near the connector and touching the end of the antenna still does the same noise but less (maybe a faulty connection inside the base plate connector ?) Any other idea? Thanks Fred Quote Link to comment Share on other sites More sharing options...
Fred Salles Posted October 19, 2018 Author Report Share Posted October 19, 2018 I also cleaned connectors with deoxit, with great hope... no change Quote Link to comment Share on other sites More sharing options...

hiro nakamura Posted October 23, 2018 Report Share Posted October 23, 2018 If you try to swap the antenna from one to another, see what happens. It might be the antenna or the transmitter side tho. Just a guess. Quote Link to comment Share on other sites More sharing options...
