I found my problem. The issue was that even though I successfully incorporated enhanced mode frequency tracking from the IC7300 to the KPA500 and KAT500, the radio was keying a x0mS burst of RF even though the frequencies were previously 'learned'. I kept looking into the Elecraft setups, manual, programming and my converter setup. The problem however was in a long overlooked menu setting in the 7300! Sometime in the past I had set "SET, CONNECTORS, FUNCTION, TUNER, PTT Start", to ON which initiates a tuning cycle to the tuner every time the VFO moves more than 1 kHz. Duh. I've been looking for this for days. I switched it to OFF and the frequency tracking works flawlessly.
In summary, I have the the IC7300 REMOTE serial data connector feeding an atmega328 microntroller (RX) developed on an Arduino Uno. The code is based on an open sourced Band Decoder by the talented guys at remoteqth.com. The TX data is now in the serial format emulating Kenwood transceivers. This data is converted to RS232 and feeds both the KPA500 and KAT500. The KPA500 menus must be configured to accept SERIAL data at the correct baud rate that the converter code and IC7300 is set to. In my case I am using 4800 baud. Although not necessary to go faster, I may try to go up in steps to the 19200 upper limit of the 7300. *Using this setup, the KPA500 switches bands as the IC7300 QSYs and even more importantly, the KAT500 senses the 7300 frequency and switches to the learned LC combinations for those band segments. This is now done WITHOUT having to send a burst of RF to the tuner to tell it what band and frequency segment we are now operating on. Contesters and DXers should find this very useful as they switch from band to band or QSYing within a band. * Of course those who operate a K3, K4, Flex or Kenwood transceiver, should be able to do this inherently. Only ICOM transceivers require this conversion.
