Just a question regarding the two-tone decoding on these radios---I set up a channel w/the 2-tone decode enabled for the particular tone sets I need, but it automatically silences all traffic on the channel until the proper set is received. Now, I *do* want it to do that, but I'd also like it to alert with the tones while you're actively listening to traffic on the channel as well, if possible. I emailed Icom tech. support, who replied that it can be done, but didn't offer what to do in the software to make it happen. Any suggestions? The software version I have is 2.0 if that makes a difference.
