<div dir="auto">Actually, the RT20 has a USB-C plug. The cable is
available from Retevis. I'm not sure what's in it, but I tried
a straight USB cable and it didn't work. Attarently there's a
serial chip (two?) In the cable. I'see if I can do some playing
around and figure out what's in it <br>

Update: I am now using CHIRP-next.
But I am completely baffled. The radio is not talking to CHIRP, but I am
baffled regarding the cable.
Can someone tell me what cable I need to connect from the RT20 to a USB
2.0 port?
Thank you!

Any programming cable with a Kenwood style 2-pin plug on the radio end
and a module containing a USB-to-Serial chip on the computer end
should work. It is best to have one using an FTDI style chip because
you can take advantage of the Apple native FTDI driver. Other chip
brands may require the purchase of 3rd party drivers. Here are a few
examples of FTDI chip based programming cables that should work.
