A few weeks ago, I made my first DX contact in years since, just recently becoming interested in this hobby again. I was driving north through Saskatchewan and spoke with Dallas TX and Niagara Falls. We spoke briefly on 38LSB but it was really crowded so the guy asked me to got to 27.390 (?) if I understood him correctly. That's between 38 and 39, right? I have no such adjustability in my old 148gtl. Could we not just have moved to 36,37,38, 39 or 40? Do newer models have this ability or did I misunderstand him?
