The frequency counter is a military tuner plate. An olive riveted panel bolted onto the deck: an engraved TUNED - HERTZ name plate, an RCVR lamp and a MHz readout, and ten Nixie tubes behind a black bezel, each with a chrome toggle switch under it. Flick a switch up and that digit's place goes up, down and it goes down, hold it and it repeats, and the lever stays where you left it. The tubes still scroll to tune and take a typed frequency. The top bar is exactly as tall as it was.
A tuning knob beside it. Drag it, scroll over it, or use the arrow and page keys while the pointer is on it. Left-click makes the step finer, right-click coarser: 100 Hz for sideband and CW, 1 kHz for the HF bands, 10 kHz for VHF and UHF, 100 kHz across the broadcast band, 1 MHz between bands. Every step moves exactly one digit of the counter, and the one you chose is remembered.
A tune the radio refused is no longer reported as one it moved. The message added in 0.87.0 for a frequency outside the radio's range could also fire when the driver was simply busy during a fast drag, naming a jump that never happened. It now speaks only for a tune the radio accepted.
