Just last week, the club had a guy in to make a presentation on packet type comms. His emphasis was on PSK 31 as an example of the several (if not many) protocols for what seems to be very narrow band radio use (meaning taking up just a few hertz of bandwidth.) From a purely personal standpoint, packet radio is one of the peripheral things that got me interested in hamming, since I have relatives that use it. I still do not have all the equipment needed to go PSK of any flavor, but am getting more interested after seeing some of the capability in the mode. So, the question is whether it makes sense to think in monkey net terms. How adaptable is it to using one pad? Is one pad even needed with the very narrow and short messages given the ability to slither around on frequencies? Any other considerations or concerns?
