Generally speaking, when contest rules do not state specifically, what are your thoughts on the following, with respect to operating a contest while mobile. If you call CQ or answer a CQ with an "indicator" on your callsign (e.g., /M for mobile), does/should that indicator be considered part of the "call" field for the purposes of logging the communication? That is, are KK5JY and KK5JY/M equivalent? If not, can you give an example of an applicable rule? The only location restrictions I can find in most contests is a "circle" in which the transmitters and receivers must be collocated, and the further restriction that antennas outside the circle must be connected to the radio(s) via RF feedlines, and not operated remotely via internet, phones, etc. Are you aware of any general rules for major contests that restrict whether the "circle" can move, as is easily done while mobile? That is, is there anything preventing the mobile from station parking somewhere, operating for a few hours, then moving, parking, and operating more from a different location? If not, can you give an example of a rule restricting such operation? I have looked at both ARRL and CQ contest rules for an answer to these questions, and I'm not finding anything definitive in either set of rules, or on either point.
