I'm trying to add some local uhf-vhf frequencies and tones to a memory bank in my TD-H5. As per instructions, I go into vfo mode, add frequency, add tone, and select an unused memory bank ie: ch-31, save, and when scanning on channel mode, ch-31 should be in the rotation. This is not working for me. This radio is identical to the Radioddity GM-30. If anyone knows how to do this, help is appreciated. Thanks
