Kenwood TK-90 HF Transceiver | Twelve Months Warranty

mean the TK-90 is transportable and installation-friendly for vehicles and base stations. The low-power settings facilitate battery- and solar-powered usage in the field.

300 memory channel capacity provides for custom operation and monitor frequency settings. Each channel has a programmable 12-character alphanumeric name for userfriendly channel selection via the backlit LCD.

The KRK-5 Remote Control Head option makes vehicular installation in any type vehicle possible. The control head can be mounted up to 7.6 meters from the transceiver unit mounted securely out of sight and out of the way under a seat, in the trunk or other compartment.

The wide viewing angle of the LCD panel makes operation easy from any position.

100W heavy-duty TX* provides the punch for long-distance communications. The twin cooling fans and the enhanced heat sink dissipation characteristics mean reliable, stable transmission performance hour after hour.
*100% duty for 30mins at 25°C, 25% duty continuous operation.

Compliance with 6 MIL-STD specifications – including shock, vibration, dust, driven rain and salt fog – assures reliable performance under the toughest conditions. The cooling intake has integral dust protection and the remote control head meets IP54 dust and water intrusion standards.

High-Stability TCXO ensures excellent frequency stability performance in most severe temperature environments.

Enhanced safety & security features include an emergency mode in all transmission modes ? V voice, CW, and Status Call. Status Call includes GPS positioning report (GPS interfaced board required). Also, the TK-90 has a non-erasable electronic serial number, a password-protected rewriteable embedded message and password-protected program data features for added security and ownership protection. Other security features support a data password.

Selective Call enables individual, group or open calling ideal for distributed networks of HF transceivers with a silent standby feature for operators. The TK-90 Selcall is compatible with its predecessor model TK-80 and handles up to 999 IDs and with a programmable ID list to assign alphanumeric names to 100 IDs.

Status Call provides up to 70 pre-canned status numbers for simple non-voice messaging and a 50 status number list with programmable alphanumeric names that provides a userfriendly display of the status message.

The optional VGS-1 Voice Guide and Storage Unit offers an audible announcement of channel numbers. Voice Storage provides four 15-second memory banks for recording memos and outgoing messages; it can also record incoming messages -15sec. x 2 channels ? V for unattended response (the calling unit must send a status call for activation). Additionally, a convenient continuous recording function means you can always play back the last 30 seconds of reception for confirmation.

Easy-installation port accommodates the optional VGS-1 unit, aftermarket GPS receiver boards or voice scrambler boards.

Data port connects external radio data modems (KCT-39 accessory interface cable option required). The KCT-39 auxiliary inputs/outputs can also be used for sensor inputs or to control external equipment.

Automatic Link Establishment (ALE) functions provided by the KPE-2 option establish automatic optimum channel links between units rather than operators searching for a frequency under varying atmospheric and noise conditions.
