I very recently purchased a KX3, which has been great. I’m used to having a rather automated shack however, and logging in the field isn’t as convenient as I’d like it to be. I’m used to using N1MM for logging and using F keys to send contest macros. While that might not be some peoples style, it’s how I operate best.
My logging app of choice for SOTA is the HamLog app by the Pignology people. My biggest problem was not remembering when I change band/mode to do so in the app. I found a handy solution that fixes my problem.
Most modern cell phones are USB OTG capable. This means you can use an adapter for you phone’s micro usb port to regular female USB, and plug things into it (flash drives, keyboards, etc). Well, in my case I wanted to see if the phone could interface with the KX3 for the app.
In the HamLog app:
Go to the Tools Menu
Scroll to "Pigtail"
Scroll to the Check box for Use USB Serial (Beta) and check the box
Change the Baud Rate to match the KX3 menu setting (I use 38400)
Go back to the Contacts menu and hit "New"
The frequency and mode should now automatically read in!
Buttons for the CQ memories are also added to the interface.
There is also another app with a built logger called KX3mate that I also got working via the same method.
I have no idea if anyone knew of this capability but I wanted to share.
