MFJ

Receiver PreSelector, 1.6 33 MHZ

MFJs new Passive Preselector has extremely high dynamic range! It improves the performance of nearly any HF or shortwave receiver/transceiver. It vastly improves the most expensive receivers. Especially helpful to those with broadband frontends that are prone to overload.

Protects your sensitive receiver input from damage (including switching diodes and attenuator resistors) caused by very strong signals from multitransmitter, multiband operation contests, field day, nearby hams, CBers, TV/FM/AM stations. It eliminates phantom signals by suppressing strong outofband signals that cause intermod, blocking and cross modulation. Completely eliminates second order intermod problems caused by strong outofband shortwave broadcast signals mixing and producing unwanted in band signals.

MFJs unique HiQ series tunable circuit gives you superb performance. The tunable series tuned circuit works into a very low impedance formed by broadband toroid transformers. Has narrow bandwidth, excellent stopband attenuation, very low loss, constant bandwidth and gain over each band. Excellent attenuation in adjacent contest bands. The entire 1.6 to 33 MHz HF band is covered in five verlapping bands.An air variable tuning capacitor, 1.8 to 1 tuning range and a vernier reduction drive gives you precision tuning.

Fully shielded metal enclosure. Tough black finish.
