  • Mixed Analog and/or Digital Operation by Channel
  • MIL-STD-810) C, D, E & F
  • Narrow and Wide band channel spacing (Analog mode)
  • P25 Digital with IMBE+2tm VOCODER
  • Analog features include CTCSS, DCS, DTMF ANI, 2-Tone (Mulit 2-tone decoding)
  • P25 features include NAC, TGID, Unit ID, Caller ID (LCD versions only)
  • Advanced Tx/Rx Battery Saver system
  • Scan, Priority Scan, Dual Watch, and Follow-me Scan
  • Mixed Mode Operation / Digital and Analog on same channel
  • Audible and Visual (LCD versions only) Signal Strength Indicators (RSSI)
  • Voice Compandor (Wide and narrow Band)
  • Emergency Features



The LCD-equipped version provides massive channel storage capability: up to 512 channels may be programmed into as many as 32 groups. A single radio may therefore be programmed with channel sets for a number of different jurisdictions or organizations, ensuring seamless interoperability. The VX-P820/P870 Series without the LCD can accommodate up to 16 channels in a single memory group.

CTCSS / DCS Encode and Decode
High-performance Encoder/Decoder circuits for both CTCSS and Digital Code Squelch are provided, for access to tone/code controlled systems. DCS is ideal for crowded RF environments, providing superior immunity from false opening of the squelch.

(optional FVP-25 required for DTMF Paging) Fleet and network operation are enhanced by the built-in DTMF ANI circuit.

2-Tone Encode and Multiple 2-Tone Decode
The VX-P820/P870 Series can transmit a 2-Tone paging call, and can receive 2-Tone calls using different tone combinations.

Rugged, Submersible Design
The VX-P820/P870 Series portables are housed in an ultra-rugged, impact-resistant case that is designed to exceed U.S. MILSTD 810C/D/E/F standards for shock, vibration, and driving rain; it also meets international waterproofing standard IP55
(water jets) and IP57 (submersion in water to a depth of 3 feet for up to 30 minutes).
For even more demanding environments, the VX-P870/P870 Series version meets IP68 specifications (submersion to 6 feet for
3 hours), and is available via special order.


Power Output: 5 W
The VX-P820/P870 Series provides up to five solid Watts of transmitter power, for extended communications range. For
more localized applications, the power output may be reduced to 2.5 W, 1 W, or 1/4 W, for enhanced battery life.

Wide / Narrow
(12.5 / 20 / 25 kHz programmable per channel)
When programming radios for use in different jurisdictions, the VX-P820/P870 Series portables may be set up, channel by channel, for use in 12.5 kHz, 20 kHz, or 25 kHz channel spacing environments. Deviation and bandwidth are automatically set according to the configuration you choose.

Built-in 5-Tone signaling
For advanced network or fleet operations, a 5-Tone Encoder-Decoder circuit is included in the VX-P820/P870 Series. An expensive option on many competing brands, this included feature enhances operation without impacting your budget.

Loud 700 mW Audio Output
Ideal for reception in noisy environments, high-powered audio of the VX-P820/P870 Series is coupled to a large internal speaker, assuring solid copy throughout difficult crowd control, fire, or sporting-event operations.

Speed Dial (16-key version only)
An easy-to-use DTMF Speed Dialer feature is included in the VX-P829/P879, for specialized selective calling, telephone interconnect, or other applications.

Voice Storage (Optional DVS-5 required)
The optional DVS-5 Digital Voice Storage Unit allows you to store and play back up to 120 seconds of incoming received audio, so you can archive an important incoming message.

Large LCD (Dot Matrix / 12 Characters +7 Segments / 3 Characters) (VX-829/824/879/874)
The large, easy-to-read display includes a 12-character dot matrix that provides a wealth of information about the operating channel, as well as various status icons. Illuminated using Vertex Standard’s renowned Omni-Glow™ back-lighting, the VX-P829/ P824/P879/P874’s LCD is clearly visible at night, with minimal degradation of your night vision.

7-Color LED for Incoming Call Alert
The front panel of the VX-P820/P870 Series includes an ultra-bright LED that can display up to seven different colors, with a variable flash pattern, to alert the operator when a 2-Tone or 5-Tone call has come in, and during Emergency mode operation.

To prevent interference to other users on busy channels, the Busy Channel Lock-Out (BCLO) and Busy Tone Lock-Out (BTLO) features prevent transmission by the portable if the channel is occupied. And the Time-Out Timer (TOT) feature will automatically cut of transmission if the programmed maximum transmit time is exceeded.

Remote Radio Stun / Kill / Revive (5-Tone)
To prevent use of the portable by an unauthorized operator (in case of theft, non-payment of subscription, etc.), a dispatch center can send a 5-Tone command to "Stun" (temporary disabling) or "Kill" (permanent disabling) a unit. If the "Stun" command has been sent, another 5-Tone "Revive" command may also be sent, re-enabling operation of the portable.

Encryption (Optional FVP-35/36 or FVP-25 required)
The FVP-35 and FVP-36 Encryption Units provide security for your important public safety and security communications.

A DTMF Paging function is also included in the FVP-25 module, for selective calling.
