That tells you "in what direction" your other VFO is set to...and that is is "off scale" for what you currently have displayed.
To prove it to yourself, push the A>B button so that both VFO's are on the same frequency. The arrow should "go away." Now turn the knob on VFO B until the marker goes off screen (either direction) and the arrow will 'show up' again. :-) de Doug KR2Q ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
