I have two questions. First, I have an Icom IC-2820H which Digirig mobile do I need, CV-I or logic Level.
Thank You

Hi @K5DLD :
Between the radios’ owner’s manuals and this link, plus the Additional Resources on the same page, you should be able to find the answer:
Selecting Digirig Mobile Serial Configuration – digirig
The signaling levels only come into play if you’re going to use the Serial cable. If you’re just using Audio (which can also do PTT BTW), the signaling levels do not matter.
All the best,

According to this post from Denis @K0TX , it does not matter:
This ICOM uses the standard MiniDin6 pinout for 1200/9600 baud operation.

1200 baud cable is part of Yaesu FT-8xx cables kit . 9600 baud cable is available separately.
There is a Data port, but the manual only describes its use for configuration cloning, serial CAT control is not mentioned so we can assume that it is not available.

As far as using Digirig Mobile (any configuration) with FT-891, please refer to this post for connections and configuration info:
Unlike other transceivers in FT-8xx lineup, Yaesu FT-891 does not expose the serial interface lines and instead implements serial CAT internally via its own USB connection.
Only the cable with MiniDin6 connector is needed on the transceiver side. Plugged into Digirig’s audio port it takes care of minimum feature set required for digital modes: audio and PTT. The PTT switch is controlled via the RTS signal of Digirig’s COM port.
The cable is available as part of Yaesu FT-8xx cables kit .
If opt…
