Description

This is a complete USED set of all 9 HF Bands Dunestar Bandpass Filters costing over £600 new. Ideal for contesters, Dxpeditions or anywhere multiple radios will be set up.
(Picture shows three of the filters only). Only ever used on one Dxpedition, so in almost as new condition.

Model 300: Single Band Bandpass Filters
Single Band, self-contained, no power required. These niine Filters cover the following 9 HF amateur bands 160, 80, 40, 30, 20, 17, 15, 12 and 10 Meters. 

This is the same module used in the Dunstar our Model 600 . No adjustments required just place in-line between transceiver and antenna or amplifier and you are ready to go.

CONSTRUCTION: The filters are 3-pole, top-C coupled. Hi-Q capacitors and inductors are used for tuned circuits. Filters are constructed on glass-epoxy PC boards. Inputs and outputs are at DC ground potentials. Aluminum Enclosure. Dimensions: HWD 2.0 X 6.0 X 1.75 Inches (including mounting flange). Ship Weight: 1-lb.
POWER RATINGS: Filters are intended for use with 200W PEP transceivers. This is not to imply a 100% duty cycle. For example, if you were to operate RTTY (100% duty) as much heating would occur as if you run SSB speech (50% duty) at the same power for twice that length of time. With compression, average power increases to 60-80% duty. CW average power is roughly comparable to speech.
