Hello, I have a problem with RF hits an inter modulation. Receivers are Lectrosonics srb, transmitters are ssm ( compatibility set to hybrid on both, audio gain set to optimal on ssm) block 25 that are connected to sl 6 and SD 688. Receivers are not upgraded to super slot compatibility. I have found last night that I need an adapter to do that. I have tried predefined frequencies, random frequencies but the problem persists. Frequency scan show no abnormal RF activity. Tuning to free frequencies, according to RF scan, did not help. Does anyone knows that these problems may be caused because of a firmware update, that I cannot do at a time because I don`t have an adapter? Thanks
