Introduction
In order to cancel out unwanted neighbouring signals on the Sony XDR-F1HD FM tuner, I constructed this phasing unit.
It can be used to attenuate strong signals which are 0,1 Mhz up or down the desired signal.
The phasing delay unit consists of 3 lengths of RG-58 that can be switched. You can delay a maximum of
310 degrees. Fine-phase tuning takes place with the LC tunable series circuit. Amplitude is regulated by the 300 ohm potmeter.
