SPATIAL FILTER 2022 MANUAL
SPATIAL FILTER 2022 was invented in 2022 and produced by Piotr Krzyżanowski SP3ABG ( e-mail sp3abg@gmail.com , www.sp3abg.taog.pl )
SPATIAL FILTER 2022 helps in listening to radio communication signals in such a way that it activates the operator's ability to listen spatially (stereo effect).
1. Insert the SPATIAL FILTER 2022 plug into the loudspeaker socket of the transceiver. Connect the 9-14V power supply. The wire marked red is + power. A separate battery may be required for high transmitter power.
2. Connect the computer headphones or 2 speakers 8-32 Ohm to the SPATIAL FILTER 2022 socket. The best effect on CW is obtained with the SSB filter on. The switch in the SPATIAL FILTER 2022 switches the headphones to the SPATIAL FILTER 2022 (ON) or directly to the transceiver (trx).
