## What is FM One?

- Frequency Lookup now tells analog from P25 by what's on the card. A tone or D code means analog, even when a NAC is listed too. It also reads words like "P25" or "analog", and flags cards that contradict themselves.
- New explanations of simplex, direct and talkaround, DCS codes, and why analog channels still store a NAC.
- The 136B and 9100 now power up with the same screens, in the same order, as the real radios.
- The 9100 display now behaves more like the real radio when you press BAND and FPP or turn the knob.
- Clearer wording in the Library and About.

- New radio: the MTP136D, a VHF P25 radio with Main and Guard receivers, a colour display and a menu-driven keypad. Like the other radios, it has Explore, Live Tips, Training lessons and troubleshooting.
- PL codes: Frequency Lookup reads Motorola PL codes such as 2Z as their tone (110.9 Hz) and explains how. Frequency cards and lessons show each tone's code, Live Tips warns you to watch for codes on cards, and pasted cards can use them.
- A new Mode menu switches between Operate, Explore and Live Tips. Learn mode is now called Explore, and Coach mode is now Live Tips.
- The Library adds the AUXFOG, whose Appendix G lists CTCSS tones and their PL codes.
- 9000: recall on the knob shows the current zone and channel, and the keys beside the screen now line up with the lines they work.
