Kenwood TK-880HK3

UHF Compact Synthesized FM Mobile Conventional/Trunking Radio

The Kenwood TK-880 Multi-Mode wireless mobile radio operates on multiple systems types: traditional two-way conventional repeater and simplex, trunking (LTR) with wide or narrow bandwidth. 

Main Features

Radios have large channel capacity:600-channel in Trunked Mode and 250-channel  in Conventional Mode. It provides more than enough channel space for company-wide, departmental and divisional requirement. The unit dynamically allocates the 32 system and 250-group memory capacity as system parameters are programmed. Each programmed system can be either set for either conventional or trunked operation.

The high-resolution dot matrix liquid crystal display furnishes the user with a simple easy-to-read interface. 

System scan and group scan permit monitoring multiple systems and talk groups for calls. Priority scanning is available with programmed conventional systems. Talk Back scan permits users to respond immediately to calls regardless of the pre-programmed or selected scan revert channels.

Alphanumeric Two-Way paging (available soon). Two-Way Alphanumeric Messaging provides the built-in capability to send and receive both pre-stored status messages and custom alphanumeric text messages. The received messages are stored in memory and can be reviewed.  Each unit has an electronic serial number for message identification.

The TK-880 mobiles have a Data Connection Port for external mobile data terminals, PC-modems (requires KCT-19 option), or Automatic Vehicle Location units.

Each key is programmable for virtually any radio feature allowing the unit to be customized to fit user needs. Sophisticated feature sets are available for special applications and supervisory personnel.

Flash memory, programming and cloning permit to make updates, advanced feature sets and system architectural changes without ever opening the unit. The radios’s flash memory can store an electronics embedded message containing owner identification, property ID numbers, user and department names, service records, etc. Cloning enables duplicating of radios in the field via a simple interface cable without the use of a PC. Additionally, all radios can have the programming password protection to prevent unauthorized program extraction and duplication.

The TK-880 is equipped with an extra-large 2.25-inch speaker element and delivers four watts of audio power for robust clarity in noisy crowds and industrial environments.

The TK-880 lightweight and compact size facilitates easy mounting even in the tight or awkward positions of today's vehicles.  The front panel can be inverted for correct viewing while leaving the built-in speaker facing away from the mounting surface. The lightweight aluminum die-cast chassis contributes to the TK-880 units' exceptional strength while providing natural transmit heat dissipation.

The radios have high quality audio with compandor noise-reduction feature enhances audio clarity on narrow bandwidth systems and is programmable per channel.  Voice intelligence components are amplified and compressed at the transmit end then re-expanded on the receive end to reproduce the original audio signal.

Public Address (PA) and Horn Alert (HA) capability is available with the optional KAP-1 unit. The PA functions outputs mic audio through the radios external speaker or can feed a more powerful external public address amplifier.  The Horn Alert output can be used to trigger a vehicle horn/light when a valid DTMF or Two-tone selective call is received.

DTMF keypad and microphone provide selective calling, system access, remote control applications and access to automatic dialing features such as the auto-dial memory for telephone interconnect and/or integrated Radio-PABX systems.

The Kenwood TK-880 meets or exceeds a full range of tough U.S. Department of Defense MIL-STD 81 0 C, D & E environmental standards.

Encryption control (optional) provides secure voice communications for law enforcement or private security from low-level inversion to high-level encryption types.

Radio lock password feature prevents unauthorized use of stolen radios with an access code to be entered every time the radio is powered up.

Built-in QT
DTMF AND 2-TONE selective call (conventional mode only)
ANI and  Emergency Call feature

Kenwood TK-880 Questions..

QHaba said:

So, I just got this Kenwood TK-880-1 Ver 2.0 UHF radio, Link to the radio, and I wanted to ask a few questions..

I have a TK-940, and a 840, and they don't transmit, program, or receive. I was wondering if this unit will be the same due to it's age?

Click to expand...

Why don't they transmit? Age shouldn't necessarily be an issue.

QHaba said:

Is there a function to field program it using the buttons?

Click to expand...

Yes, there are ways to do it. However, it requires the programming software to set it up, put in the alpha/numeric names, as well as set up the rest of the radio functions. The Front Panel Programming only lets you change some very basic settings.

QHaba said:

Will I be able to get on the frequency of 457.6625 with a PL tone of D043N, and another channel on the same frequency with a PL tone of D023N, by field programming it?

Click to expand...

If you use the software. You can do it with the front panel programming, but it takes some work and the software to set it up. Don't rely on the front panel programming, get the software and cable, it makes life a lot easier.

QHaba said:

Will this radio work on 13.8 volts and function properly?

Click to expand...

Yes, but you need to have a power supply that will provide enough current to make it work. For receive only you'll need about 2 amps. If you want to transmit, you'll need at least 10 amps.

QHaba said:

Do I need the power cord, and not just the cord on the radio, or can I just use the radio's cord without the power cord?

Click to expand...

You -could- cut off the connector on the end and attach another type of connector to fit your needs. Just remember you need to have fuses installed.

QHaba said:

And last but not least, could I take a random frequency (for example, 462.7725), and use that in the state of Minnesota, legally? I have a Kenwood TK-3200L, and I want to be able to have my "own" frequency that I can use without a license. Or else could I use some uniden/cobra toy walkie talkies and use those frequencies legally?

Click to expand...

No.

There are no "license free" frequencies that those radios will work on. They do no qualify under FRS rules, so you cannot legally use it there.
If you have a valid FCC issued GMRS, amateur radio, or Part 90 license, you can use the radios under those licenses on their appropriate frequencies only.

Transmitting without a license of your own would be in violation of the FCC rules. There are no exceptions to that.

She waved her hand after me when I went down half a flight, and after walking two floors down, I heard how she went to. Her room and slammed the door. I left the entrance: the darkness - even if you gouge out your eyes, the rain has calmed down a little. But still dripping, there are no souls on the street.

And I didn't get lost - I grabbed it by the belt and sat it on my lap. I got rid of the squeal in my ears with a kiss. When they kissed, he picked up his beloved in his arms and carried her into the house. She buried herself in my armpit, became quiet. I only moved when I realized that I was carrying her up the stairs to the second floor, to the bedroom.
