Vic, (WA4THR), I had not thought that a 100 watt TT rig would be a problem for the LDG autotuners. What happens if you forget to turn the power back when you tune up the match? If you had the 200 watt version of the LDG tuner,is it safe to say that it would not be an issue? Thanks for the feedback Vic. Roger Rippy W7RIP Bozeman, Montana
