OK, I searched (though I bet it's here somewhere if my search-fu was better..:confused: ) - I acquired an VHF XTS-5K with 4.80.00 Host & DSP. It seems to do everything I want it to - except MPL. I've checked the box in the zone/channel entry, entered plenty of values on the MPL table, but I can't get the "MPL" button to show up in either the menu, or function if its set to a button. Is my firmware too olde for MPL or have I missed something?
I see I can get 64 MPLs by upgrading to 19.x.x, so I might uplift it anyway..:)
