The KAT500/KPA1500 Tuner Trainer software is designed to have the K4 transceiver transmit a signal sufficient to automatically initiate a tune cycle in the Elecraft tuner to find a setting that produces a low SWR for every frequency segment for every band. (See p. 27 of the Elecraft KAT500 or p. 24 of the Elecraft KPA1500 Owner’s Manual for details on how this tuning works.)

Note: Some have mentioned that their computers flag this as having a virus, which I think is a false positive. Windows and some browsers also often automatically flag an executable file (even zipped) as possible malware if it’s downloaded off the internet. I ran a virus scan on my machine with both BitDefender and Microsoft Defender. They found NO virus on my computer or in this file.
