It is almost OK, but still shows some odd behavior.
One thing is that I can not change the IF filter, and another is that I can not receive the echo back correctly for a TX power command. The latter could be due to my program, but the IF filter control does not work either with Flrig, with which I am sending just a hex sequence.
Anyway, I rarely touch the front panel of my IC-7410 now, and I am quite satisfied with that.
