hi to the group, have a 706mk2 and a ah2 tuner and would like to know if these two are compatible. manual on I've been using an AH-2 with my MK2 for quite a while - it works fine. I use it both on ham bands and AF MARS with an open-wire-fed dipole. The AH-2 does not cover 6 meters, though. 73 Bob WA2UEH
