DMM repeater operation is problematic if you want to actually converse. Make all the radios either analog or digital. What kind of portable radios are you using?
On Motorola radios, you need to specify a TX Contact in order for the channel to work. You DO NOT need to specify an 'RX Group List'. The radio will automagically receive the contact code and contact code ONLY and ONLY on the slot you specify.
Please get some training. Is this an amateur or commercial installation? If commercial, get someone to make sure your radios are programmed in accordance to your license.
As stated before, you need a professional to set this up for you.
