Hi James,
thank you very much for your answer!
Yes, I think this issue is quite seldom... but in the meanwhile I saw a picture in the internet, where another guy had the "I"-character on a 70 cm frequency... so I'm not the only one.
Yes, I think the "I" in the display is the only problem and I'm sure, that the receiver worked with its full sensivity. Nothing changed after correcting the problem via CHIRP.
The problem happened, as I stored many frequencies into the memories. I didn't want to do a reset, because it's quite a lot work to set all my memories. But as I've been "forced" to use CHIRP, I saw that is really easy to handle and now it's a fun to set and edit my memories...
Again, thank you and
