I am sure I am asking this in a newbie fashion but I am lost.  I purchased a Rugged Radio GMR25 which is a rebranded TYT TH-8600 unit.  The unit has the standard GMRS channels/frequencies but then they have a "sub channel".  So channel 1 has 1, 1-10, 1-25 and 2 has 2, 2-10, 2-25 and so on.  My TD-H3 can scan the freq and shows the correct GMRS freq + code 94.8 for -10 and 156.7 for the -25 channel.  So I go into Chirp and see how the TD saves it.  It saves it as a TSQL and the Tone Squelch at the 94.8.  I can hear the Rugged radio but when I send from the TD to the Rugged nothing.   I want to be able to use these sub channels on my hand held but not sure what else needs to be done to TX.
 
Thanks
 
 

Sub channels are a misnomer.  There are only 30 channels in GMRS. Subchannels refer to a tone or digital code which is used to tell a radio when to ignore transmissions and it’s just another name for CTCSS, PL, etc.  Every repeater will have a CTCSS tone or a DCS tone on the input, which your transmit tone MUST match or the repeater will ignore your transmission.
However, the tone mode is less limited.  Right now you say Chirp shows you’re set to TSQL.  That means your radio will only break squelch if that particular tone is received. If you set that to TONE, instead of TSQL, it will still send the tone you program, but it will allow anything through.  That’s especially helpful when you’re getting started so you can hear someone tell you you’re using the wrong tone.

You have to transmit the codes from the TD-H3.  Put them into function 13, Tx CTCSS.  Put the H3 on the frequency and then press the blue button, press 1 then 3 and press the blue button again and then the up button until you reach the proper tone and press the blue button again. 
Should transmit and receive after that.

You are going to need to research the PL / DPL codes that the 'subchannels' have assigned to them. 
Obviously it's going to be using the assigned frequencies for the channels, so the only 'sub' to it is PL tones for transmit and receive.
