It is possible to setup a memory for each repeater frequency and also set-up the various R1 and R2 settings for each repeater.

You can store multiple entries for the repeater with different R1 and R2 data for each memory to make it easier to change the R1 and R2 by simple selecting a different memory channel.

If anyone wishes to get their 2820 programmed up then you are welcome to contact me to allow for this to be done. It only takes a few minutes using the settings I have.
