Any chance for 6-place grid squares at VHF & higher?
Of course you can send a 6-character locator as part of a free text
message.
But as a JT-style structured message??
Think about it this way: A 4-character Maidenhead locator fits in a
15-bit field. A 6-character locator must allow for AA to RR as the
final two characters. That's another 18 x 18 = 324 possibilities, or
another 9 bits. All 72 bits in the JT structured messages are "spoken
for". We don't have 9 unassigned and available bits.
