Steef, See this recent post for explanation: http://mailman.qth.net/pipermail/elecraft/2021-April/284736.html.
The KAT500 can auto-track any Kenwood or Kenwood-compatible rig that outputs frequency data in the format: "FA00014025000;". Connect the RS232 RXD line (Pin 2) of the Kenwood rig to the TXD line (tip) of KAT500 PC DATA connector, with no connection on ring. You have to use the BR; command to set the baud rate of the KAT500 PC DATA jack to match the rig's RS232 baud rate. You can also uise a program like N4PY Pegasus Plus <http://www.n4py.com/pegasus-plus.html> to keep the KAT500 / KPA500 in sync. with the rig. The S-BOX-USB provides either capability using standard commercial stereo and serial cables, with parallel wiring to all logging programs and the KPA500 XCVR SERIAL connector, so no splitters or custom cables are required. If you're using a TS-590S with a working USB port, you can connect the computer to the USB port and connect both the KPA500 / KAT500 to the TS-590S COM port with such wiring (only wired RXD in parallel, never TXD). Modern Yaesu rigs do not output enough digits of information in the FA command output (they drop most of the leading zeroes). The KPA1500 firmware can handle the Yaesu format of FA frequency data to auto-track, but the KPA500 and KAT500 cannot, though they could potentially be updated to do that. 73, Bob, N6TV https://bit.ly/S-BOX On Sat, May 8, 2021 at 4:59 AM <[email protected]> wrote: > Hi, > > if I switch the KPA500 with the band buttons to another band I would > expect the KAT500 to follow the last tune settings on the new band.
