This is in CW mode. If I change filter width while the RIT has an offset, the next time you adjust frequency or RIT, the P3 will not track accurately. Even if you turn RIT off, the P3 will still not track frequency accurately with the K3 until you turn the P3 off and back on. I have experienced this with P3 v3.8 and v4.1. K3 is running 4.22. KG7MZ
