I never worked with an IC FR4000 and I had a request to help a group of ham make a DMR repeater from a FR4000.
?
To do it, we need to have flat audio in and out. and I was able to find the information for the TX section. But the RX I am not sure.?
?
?
the way I see it, Pin 9 is ok for the TX side??
and pin 12 is ok for the RX side??
?
Anyone ever used that repeater for DMR?
?
Thanks
