DETECTOR SINCRONO PARA RECEPTORES


y bueno era algo fuera de serie, incluso el tÃpico "fadding" desaparece de forma asombrosa, todo y que esto ya lo hace la detección sincrona,pero en este caso el cambio es espectacular, superior a la que se nota en el AOR 7030,todo y que su receptor era inferior, no me extraña el fabricante Sherwood, siempre se ha destacado por sus productos totalmente profesionales y de gran calidad.
Como os podeis imaginar enseguida le pedi que si me podia mandar uno de EEUU, se que el me conseguiria el mejor precio de envio y compra, pero la sorpresa fue su precio..

SE-3 MK IV
High-Fidelity Phase-Locked AM Product Detector


The SE-3 MK IIID High-Fidelity Phase-Locked AM Product Detector eliminates selective-fade distortion and garbling. It permits your receiver to receive one sideband at a time to minimize interference and double the fidelity of the detected audio.
Eliminates Selective-Fade Distortion and Garbling
Able to Receive One Sideband at a Time to Minimize Interference
#
Synchro-phase (envelope) detector for conventional operation or rapid scanning. Allows SE-3 output to be used at all times.
#
High-frequency roll-off and boost tone control to compensate for poor-quality program material or to correct for speaker roll-off. Three positions: flat, 5 dB boost at 5kHz, or 5 dB cut at 5 kHz.
#
Flutter filter for multi-path and time delay distortion.
#
Buffered auxiliary output for recording or driving other accessories.
#
Guide lock switch for manually guiding the PLL into lock.
#
Manual BFO for SSB reception.
#
Audio notch (whistle filter) at 5 kHz is optimized for shortwave channel spacing.
#
A transformer, with cable and mating connector, is supplied with each SE-3 for operation with 120 V. AC mains. Transformer supplies 20 V. AC at 1/2 amp.
Please specify receiver model or IF level if known
System bandwidth is determined by receiver i-f bandwidth:
*
6-kHz filter would give response to 6 kHz when run with full LSB or USB offset.
*
SE-3 response: 30 Hz to 15 kHz at -3 dB.
*
SE-3 IF input requirements: 30 mV. to 2V. RMS at 455 kHz.
*
Speaker impedance: 4 ohms or greater.
*
Auxiliary output: 300 mV RMS.
