[Elecraft] [KAT500] Mac KAT500 Utility Software Issue

[Scott Ririe]

I’m a relatively new owner of a new KAT500 and KPA500 Power Combo. I’m also an Apple Mac user. When changing bands, the amp has been faulting. I then re-tune, put amp back in ‘Oper’ mode and I’m good until I change bands again. I reached out to support and they had me check the ‘Amp Key Interrupt Pwr’ setting on the tuner via the KAT500 Utility Software. It appears to have been set to ‘1’ instead of ‘Optimize the KPA500’ @ 1500 watts. The interesting thing is that every time I click ‘Optimize the KPA500’ button, do an ‘apply’ and then ‘ok’, and when I come back into that menu it was always reset to back to ‘1’. Very odd!

I decided to install the Windows version of the KAT500 Utility Software on another computer. When using the windows version, the ‘Optimize the KPA500’ setting sticks and no more faults on the amp when I change bands. It looks like there may be a defect in the Mac version of the KAT500 utility.

Any of you Mac users with a KAT500/KPA500 had this problem when using the Mac version of the KAT500 utility?

Thanks,
