RD Series

The Motorola RD Series was a popular line of analog business radios — the RDU4100, RDU4160D and RDV5100 — known for being tough, simple and dependable.

All three have been discontinued. The closest replacement is the Motorola CP100d, which can be pre-programmed to match your existing RD channels so new radios talk to your current fleet from day one. The BPR50dX is the alternative if you want a radio that also supports digital.
