On the Kenwood TH-D75A, you can put Band B, the lower display, into Memory Channel mode while Band A remains in whatever mode you want.
- Press [A/B] until Band B is the active/selected band. The TH-D75A uses
[A/B]to select which band you are controlling. - Press [MR].
- Band B should now display one of your programmed memory channels.
- Rotate the ENC knob to move through the memory channels.
Kenwood confirms that pressing [MR] enters Memory Channel mode. By default, it allows recall from all memory groups.
So you can have something like:
Band A144.390 APRS
Band B147.045 W3PIE
or whatever memory channel name you programmed.
If you only want a particular group on Band B
Once Band B is in Memory mode, press and hold ◀ or ▶ to select a memory group. For example, you could make one group contain only your local repeaters.
Important: use a normal press of [A/B] to select Band B. Do not press [F] + [A/B], because that changes between dual-band and single-band display modes.
If you want, I can also show you how to make Band B display the memory NAME, such as W3PIE 147.045, instead of primarily showing the frequency.
