MULTIPLE CRYSTAL FRONT END FILTERS BOARD FOR 40M


40M front end unit with 800Hz narrow Crystal filters for each kHz, from 7011 to 7025 kHz, all controlled from MCU.


This front end unit was designed by Sinisa, YT1NT. Year ago, I ordered 15 peaces of 6 pole crystal filters, 800 Hz wide ( +/- 3dB ) with central frequencies from 7011 up to 7025, on each kilocycle.

Description

This product has been discontinued. Can be made by a custom order order only.

With CFE unit, signals are being listening through multiple narrow crystal filter directly on antenna. This amzingly decrease S/N ratio of your receiver, and improve IMD resistance incrediably.

Two models available: CFE15, with 15 sockets for 15 crystal front end filters and CFE30, with 30 sockets for 30 crystal front end filters.

CFE can be used with any transciever. Thanks to CAT control, CFE is connected on your radio and crystal filters will be swithched automaticaly.

On large LCD display you can easily see your frequency “position” inside filter curennly in use, and all other needed information.

You can have two of these units work in network, on the same band, what make incrediable isolation of two receiver on close frequencies. It make SO, Single Band Two radio operating much more comfortable.
