Hello, I'm a new list member in MN. Have had a 756PRO3 for about a week and LOVE it. Acquired a IC-4KL amp yesterday and noticed that it generates noise on 20, 18 and 15. You can even see it on the 756 Spectrum Scope. Anybody had experience with this problem? Thanks and Best Seasons Greetings to all. 73, Mike Warren - K0MAZ
