Motorola PTX series (PTX700/760/780) portable walkie talkies

The Motorola PTX700/760/780 is a portable professional walkie talkie compatible with the MPT1327 cluster standard, aimed at industries such as public safety, utilities, and transportation. It has common functions such as 12.5/20/25kHz programmable channel spacing, X-PANDIM voice enhancement technology, MAP27 data interface, and supports multiple communication modes such as individual calls, group calls, and emergency calls; The differences among the three models are reflected in the number of personalized configurations (2/4/60), contact list capacity (16/40/40), programmable dedicated call buttons (3/3/6), and advanced functions (PTX780 adds built-in voice storage and ultra long data message transmission), paired with NiMH/NiCD/Li ion batteries (weight 350-535gm, range 8-14 hours), with industrial grade reliability such as IP54 protection and shock and vibration resistance, meeting the efficient communication needs in mobile scenarios.

Overall positioning and core commonalities of the product

Core positioning: All three walkie talkies are professional equipment from the Motorola MPT Trunked series, designed based on the MPT1327 cluster communication standard, with a focus on “instant messaging in mobile”. They are suitable for team collaboration and emergency dispatch needs in multiple industry scenarios, and have the advantages of efficient channel sharing and wide coverage of cluster systems.

Common core functions

Communication modes: Full coverage of individual calls, group calls, fleet calls, inter fleet calls, broadcast calls, emergency calls (with dedicated buttons, prioritized when the system is busy), PABX/PSTN public network calls, meeting diverse communication needs.

Audio technology: equipped with X-PANDIM patented speech compression and expansion technology, improving speech clarity in noisy environments; The low-level expansion function reduces background noise during call intervals, further optimizing audio quality.

Data and Interface: Both are equipped with MAP27 data interface, supporting data message transmission and remote control of walkie talkies; PTX760/780 supports an additional 32 alphanumeric short data status message programming, and PTX780 can transmit data messages of any length through business channels (requiring a matching modem).

Channel and Expansion: Supports programmable channel spacing of 12.5/20/25kHz to adapt to different frequency band resources; Under normal mode, each model supports 16 channels; Voice storage and Mandown alarm functions can be expanded through optional boards.

Reliability design: IP54 level sealed protection, able to withstand rain; The shell is resistant to impact and vibration, complying with MIL-STD 810 C/D/E and TIA/EIA 603 standards; Dustproof and moisture-proof, suitable for harsh industrial environments.
