VHF/FM Transceiver FM-2025 A & E

The KDK FM2025E is a 12V DC two-metre FM transceiver for mobile or base station use. Although feature-packed, operational ease is assured by the use of a "custom microprocessor.

Digital frequency synthesis provides full band coverage in 12-5kHz or 25kHz steps. "Single knob" frequency selection is by an optically coupled encoder. A dialing speed switch (increases tuning steps) facilitates rapid QSY's.

A 10-slot memory with Ni-Cad back-up, provides 10 duplex (plus + 600kHz shift) and/or 5 semi-duplex channels, making the 2025 as easy to use mobile as a crystal-controlled transceiver.
One memory is semi-dedicated to "priority" and programmable when the 2025 is dial controlled.

The 2025 embodies the best non-lockout scanner. It scans occupied or empty channels, and a flick switch enables immediate transmission. The scanner works on the memories and across any selected portion of the band (scan limits are defined by two of the memories).

Features;

• Custom-designed microprocessor control
• 25kHz and 12.5kHz synthesizer steps!!
• Instant OSY', 10 times rate button
• 25 Watts of reliable RF output
• Band scan between any 'easy set' limits
• 10 write-in non-volatile memory channels
• Memory scanning with hold facility
• Standard -± 600kHz or any repeater split

Dual gate UHF MOSFETS in the RF and mixer provide superior intermodulation performance with high sensitivity maintained over the band by auto-varicap tuning. A monolithic crystal filter in the first IF and a 15-pole ceramic filter in the second provides excellent selectivity.

The single conversion transmitter uses a balanced mixer and a VCO on the signal frequency (directly modulated for superb FM) and a hybrid power module for 25 W (or 3W) RF.

The PA is impervious to breakdowns under infinite VSVVR. Necessary control function instructions are programmed into the microprocessor itself. But by re-arranging a diode matrix, the lower frequency transceive limit, the high frequency receive limit and the high frequency transmit limit may be altered to allow for changes in band plan or location.

Switchable auto-tone-burst, RF attenuator, squelch, microphone, microphone clip, power lead, mounting bracket, handbook are, of course, part of the package.
