Noticed yesterday during OK RTTY that have to turn SHIFT knob to about 1oclock for my MKV to be centered on RTTY sigs when in NAR2 (both inrad 250's). Sigs are centered FB with no SHIFT adjustment when in NAR1 (stock 500 and 400 inrad). Could have sworn that I didn't have to do this the last time I worked RTTY, but I could be wrong. What's the story? Blake N4GI
