The OP mentioned using a repeater channel to talk to the other radio but has no repeater nearby. Also, the display shows a plus sign. That is because you are transmitting on 467.xxx mhz but receiving on 462.xxx mhz. You can not talk to your other radio on simplex using a repeater channel by default regardless of ctcss tones/codes. Switch to a simplex channel and try again with codes.
Radioddity GM 30 will not transmit CTCSS codes to either Midland or Wouxon HT's.
