[Elecraft] KAT500: Not remembering antenna configuration

[JK Hooper]

Hi all, 

Here is an update on my KAT500 Mac software utility problem, described below. 

I am able to configure my KAT500 just fine with the Windows version of the KAT500 Utility using Windows 10 O/S, so, effectively, my “problem” of configuring the KAT500 is solved.   

The Mac version of the KAT500 utility does not appear to be working correctly with macOS Ventura 13.2.1, at least on my computer.  

I have let Elecraft support know.  

Special thanks to Andy K3WYC who emailed me quite a few times with suggestions on troubleshooting and he pointed the way for me to track things down.

Any insights on troubleshooting approaches for my KAT500 S/N 015XX which is not remembering the antenna configurations I enter.   K4D - KPA500 - KAT500.  KAT500 gets its power from the K4D auxiliary DC port.   

KAT500 is running latest firmware version 02.05.   Mac Utility is version 1.21.10.9.   I have reinstalled firmware.  No change.   I have reset to factory configuration, then reloaded configuration, no change.   

Some “for examples”: 

1. Each time I open the KAT500 utility, the Maximum power (watts) on the Edit Configuration tab reverts to “1” watt.   I previously selected “Optimize for KAT500.” 

2. I will assign 20 m to both ANT 2 and ANT 3, for example, but this configuration reverts to no “Enabled” antennas and Preferred is “Ant 2.” 

On the other hand, the KAT500 appears to have correctly memorized the tuning settings.   I operate with KAT500 in “MAN” and have previously gone through the bands memorizing tuning settings. 

The specific problem I have is that, for 6 meters, I want to use ANT 2 but the KAT500 is not letting me change from ANT 3.   

And while I am not using ANT 1, I’m not able to configure a band/antenna combination such that I can only switch between ANT 2 and ANT 3. 

Thanks in advance,
