Scott, Every ATU design has different stray amounts of L and C. But the differences are small between the KPA1500 ATU and our other ATUs, especially the battlefield-proven KAT500, which has a virtually identical circuit. We test the ATUs into various loads to verify matching range.
That said, if you believe yours has a matching range problem, please contact support. There’s even the possibility it’s a firmware issue. 73, Wayne N6KR > On Jun 16, 2018, at 1:26 PM, K9MA <[email protected]> wrote: > > I've also noticed that the ATU often doesn't get a very good match, even if I > try twice as per the manual.
