AT RF13D Duplex VHF Transceiver
| AT RF13D is a VHF transceiver designed for duplex data operation. AT RF13D design is based on AT RF13 transceiver, the difference being in an added independent input for receiving antenna, modified AF paths and modified control program. It is used in a set with ZM13.1 (ZV13.1) power amplifier, AF13, AF13.1 co-site filters. The transceiver can be operated independently with RF13 transceiver accessories. |
