Just looked at your Web site and you have an HF-Auto not an AT-Auto so I don't know if my approach applies or not - don't know how much Palstar had to change when Don left with the AT-Auto design rights.
I'd like to have the AT-AUTO follow frequency changes via FLEX CAT without the need to TX. Anyone out there using the AT-AUTO (not HF-AUTO) in this fashion?
Ahh! the HF-AUTO in my shack photo, I see how that could be confusing! The AT-AUTO may be used in another station set-up and I was hoping to get some feedback before I purchased it.
Thanks for all your feedback!
I have tested the AT-Auto with USB to serial cable plugged into the radio. It does work fine. I was using Kessler Engineering's 2.14 firmware but should work with the PalStar firmware also.
In PalStar setup make sure to set radio type to Kenwood CAT only, no Ext Tuner I/O. Document baud rate and make sure you select 8,n,1.
In the radio USB setting menu set cable type to CAT and set baud rate.
The advantage of connecting CAT to the tuner is the tuner can pre-tune before applying RF. I had modified my AT-Auto to remove the balun and install a second coax connector. I programmed the tuner to automatically switch antennas when switching bands and also automatically bypass the tuner on bands where the antenna was resonant.
