Hi!

Cqrlog does not have any limits.
The limit is your Linux. Does recognize your micro ham device?

Linux is not Windoze, so serial ports are not called COMx. They are like /dev/ttyXXXXXX
When you MIcro Ham is NOT connected to your Linux open command terminal and give command:
ls /dev/

Note specially names that begin as tty or ACM

Then connect your Micro ham and give again same command:
ls /dev/

Did there appear one or several names more that begin with tty or ACM ?

If did they are your Micro Ham ports.
Next question is does Hamlib support Micro Ham ports?.

Again Cqrlog does not make any radio support. All are made via Hamlib program.
If Hamlib suppots it, then Cqrlog supports it.

Same with Rotators. If Hamlib suppots it, then Cqrlog supports it.

Simply as that.
If Micro Ham is pure Windoze device it many not be supported by Linux.
