If it is encrypted, there's no problem. Anyone with a portable
shortwave receiver can sit outside some embassy and figure out at least
one of the frequencies being used. Any host country with any sort of
security service could figure out which transmit frequency is in use
within a couple of minutes. They just don't know what is being transmitted.
