I'm aware that there are 40 channels availible, but doing somre research (including the modem manufactor's website,
http://www.electrowave.com/. did you know they make a special modem only for FIRST?) seems to suggest only 5 channels are used. Channel 40 is the default channel, it is the only one you can use without a competition port pluged in. With the port, there are 4 addition channels unlocked. According to the modem manual "While the modem is capable of using 40 channels, only 5 channels are available to the user in the standard modems" The comp port wiring diagram agrees, they give you 5 channels to use (if you manualy select them). If IF does enable all 40 channels for comp, doesn't that mean the mobile modem has to scan through 40 channels looking for a signal <i>every</i/> time as it doesn't know if the extra channels are enabled ahead of time?
