[Elecraft] K3: Erratic behavior of REV button

[J. Wolf]

Sometimes with my K3 I find it useful when operating split to do so without dual receive. When I do this, I want to be able to monitor the "B" transmit frequency periodically. This is easy with the REV button. The problem is that sometimes, after releasing the REV button, the radio pops out of split mode. When I don't notice this, I end up transmitting on the wrong VFO, and you know what that means. ("Up! Up!") Is this a problem others have seen or do I have an isolated malfunction? Anyone got any input on this?
