DN5VF

This is for example a RF- Clipper designed by DF4ZS (it is running on 455 kHz) with good results. In my 2m TRX I am using a RF- Clipper with 2x 9 MHz Quarzfilters. After collecting some reports I couldn’t found any difference to the first descreibed RF-Clipper. But when I use this exelent RF-Clipper circuit it is showing results succesfully . When I built this circuits up I am using technics whit old part and also new one SMD e.g. whatever I found in the drawer of my working place table.

This Broadband coupler is good for 1.5 - 55 MHz Original described in the ARRL Handbook. I am using 2 Amidon cores T50-2. Diodes are Schottky hp2800. It is built in 4 rectifiers for positive (2) and negative (2) to rectifire for forward and backward waves.Therefore I am able to use this Coupler for automatic controls to stearing directions of tuning.
