I was surprised to find that 868.775 (licensed to Horry County) is an extremely active frequency here in the Myrtle Beach area, with a very strong signal. The transmissions have a PL of 156.7 on them and after listening for a while I can confirm that it is simulcasting the "SCHP Ch-70 Horry" talkgroup (29328) from the Palm-800 trunk system! I am fairly certain that it is also simulcasting at least one, or more, other users, but I am not certain if they are from the Palm-800 system, or from somewhere else. The heaviest traffic is from the "Florence" dispatcher on CH-70 and both the dispatcher and the cars are simulcast on 868.775/156.7 .
