COMPLETELY SOLID STATE Mosfet mixers for excellent I.M. and cross modulation performance. J-FET oscillators for stability. I.C.'s used in digital frequency counter, balanced modulator, receiver I.F. amplifier, and audio output for functional simplicity. No relays.
DIGITAL DIAL Frequency can be read at a glance. 0.3 inch L.E.D. displays are easily visible. Frequency counter offers 100 Hz. accuracy.
SPEECH COMPRESSOR Increases average output power approximately 6 db. Level set by mic control.
NOISE BLANKER Noise pulses are blanked ahead of the crystal filter for optimum reduction of interference.
100 WATTS INPUT P.E.P. or C.W. 50 watts output (minimum).
BROADBAND OUTPUT Infinite VSWR protection. Multiple pi section low-pass filter for minimum spurious output.
RECEIVER FRONT END DESIGN AGC controlled pin diode R.F. attenuator for low distortion large signal handling capabilities. riple tuned preselector offers superior R.F. selectivity.
QUALITY CONSTRUCTION Utilizing glass epoxy P.C. boards and commercial grade components. All electrical connections soldered for reliability. P.C. boards accessible for easy servicing.
STANDARD ACCESSORIES Mobile mounting bracket and power connector with 8 foot battery cable are supplied with unit.
