Add OLED special chars (TNX Jokubas, LY5NF, Noli Rafallo), add smaller OLED font (see CONDENSED config switch, TNX Pedro CT1CAH), add primitive OLED cursor. Add audio streaming over 115200 baud serial CAT (enable with UA1; cmd), read-out display contents (UD;), send key-presses (UK;), add no-display support (BLIND config switch). Add supply-voltage read-out option in smeter (TNX Jeff WB4LCG). Add 160m and Noise Gate menu option.
