Put a dummy load on output of KAT500 and if that doesn't give 1:1 then you have a cable issue.

See just prior response. Also, K3s power set at ABOVE 7 watts,,,, both 10 Watts and above 12-13 to engage K3 PA... Trying to tune using the KAT500 causes the blinking mode light and an obvious break in the rf signal path to the antenna... What is key is that KAT500 in Bypass, K3s in Bypass, TUNE gives 3.6:1... Put KAT500 in Manual and TUNE on K3s gives 12.6:1 or higher. Do it in AUTO and the KAT500 kicks out, blinking mode, 99.9:1 SWR... obvious signal path disco. 73, ______________________ Clay Autery, KY5G MONTAC Enterprises (318) 518-1389 On 8/8/2017 11:37 AM, ab2tc wrote: > Hi Clay, > > I could easily reproduce your problem.
