Drew I don't pay any attention to groups and channels. Where did you learn this? I have heard a few techs particularly in rock and roll say this. I have to say I have never seen wwb generate a coordination with all channels from the same group. Typically they are all over the place. I do not use the on board built in coordination function inside the hardware. I was burned early on using the hardware coordination back when we first got 16 channels of uhfr at Show Systems. In a wwb coordination you can choose more freqs, standard, or more robust. More freqs looks at 2 transmitter 3rds like the hardware does. More robust avoids the worst case imd caused by 3 transmitters up to 7ths or 9ths (I don't remember). I use the more robust coordination whenever possible. I only resort to more freqs or standard when I'm zoning a bunch of systems for breakout rooms in which case I still spread the frequencies in a given room out a bit and put the frequencies that would be in the spaces between in another room to get some distance. I use the hardware or the win radio to scan within wwb. I very seldomly find 3 transmitter imd issues using more robust. I find these by piling up the transmitters and turning them off one at a time. If the signal doesn't completely go away then there is imd. Usually the problem transmitters can be found by turning one more off at a time until the contributing units are found. Usually just separating them a few feet solves the issue but I like to be aware of the potential for problems. If I can change a freq, I do but if not I don't worry too much. Even when double micing I will tend to separate the packs. Also during the show all packs that are not used are off and all packs that are going to be used soon by still in rf land are separated. A common trick is to shield them with tin foil lined boxes but I don't find that necessary. I also lock the units, switch them off and pop the batteries out and back in. When it's time to turn them on they are already locked. The common practice of burning your rf all day and night to save the frequencies doesn't work. It doesn't take into account the imd caused by the idiots in the hotel that just randomly choose frequencies based on the Rf level on the LCD screen. I have found this method to work well and I carry my only switches and routers because about 50%of the racks don't have any networking set up in the first place.I am working with Bexal's top gun this week. Their sop is to use ias to coordinate freqs then use a spectrum analyzer on site to find any unknown issues. Ones the final freqs are chosen all the normal testing is done just as I described. It's always good to coordinate spare freqs so you can make a change without having to start from scratch. All of this applies to pretty much any wireless but works well with uhfr. Other units and manufacturers may have more problems with outside interference or less happy transmitters. The basic sop still applies though. I am not a fan of mixing rf systems particularly in the same general band split. The distortion in one manufacturers transmitter may cause problems in another manufacturers reciever. I too know just enough to be dangerous but rf has been a hobby for me since I was a kid so I really enjoy learning more about it.
