Happy Father’s Day to you as well.
First, are you on a repeater channel? You didn’t say what channel you’re on. On all GMRS radios there are the simplex channels 15 - 22 and there are the repeater channels which are numbered 23 - 30 or something like RP15 - RP22. The repeater channels and the simplex channels receive on the same frequencies, which is in the 462 MHz range. So, channel 15 receives on exactly the same frequency as 23 (or RP15), 16 receives on the same frequency as 24 (RP16), etc.
The difference is that the repeater channels transmit at a frequency that is usually 5.000 MHz higher than the simplex channel. So channel 15 receives and transmits on 462.550 MHz, channel 23 (RP15) transmits on 467.550 MHz. Because you mentioned that you’re able to receive just fine, it could be that you’re transmitting on the simplex channel, which would never wake up the receiver.
