Well regardless if wether 1.7mhz split in the 6 meter band is or is not a national US band plan split it is an excepted split by the Kansas State Repeater Cordinator as my repeater is cordinated on 52.850/51.150 by them and has been for over 2 years. Just getting it back on the air at a new site. Wasn't trying a war here just trying to get some answers on the db isolation needed and exceptibale vertical antenna seperation needed for a 1.7mhz split on 6 meters, which is my reason for posting but have failed to see anyone give the answers I needed.
