I have a Sony 2001D/ 2010 and a NRD-525. The NRD has no sync detection and it runs circles around the Sony in *every* aspect. It should! I just switch to SSB-mode selecting the sideband and the bandwidth wich is working best. I'm rarely listenig in AM-mode. If you had a good sync detector, you might listen more in AM mode. A good sync detector basically provides auto-ECSS. -- Brian Denley http://home.comcast.net/~b.denley/index.html |

A good sync detector basically provides auto-ECSS. AFAIK the NRD-525 *is* in ECSS-mode when switched to AM. It allways adds its own carrier frequency, except when switched to FM mode. Nontheless I like SSB much more than AM. |

Nontheless I like SSB much more than AM. Actually it is true ECSS. The carrier is derived form the input signal so there is no need for careful tuning. craigm |

Switching to SSB is easily done without shifting. And with some additional IF-filters you can switch to the bandwidth working best in conjunktion with bandpass shift. |

OK, I was wondering about the ECSS in AM mode. |

Volker: Yes but in true AM ECSS mode (syncronous demodulation), the zero beating is automatic and tracks. You don't have to keep adjusting. Drift doesn't matter, music comes in perfectly, it's locked! That is superior to any manual ECSS mode. -- Brian Denley http://home.comcast.net/~b.denley/index.html |

I just fire it up and it sits on the frequency like a Buddha with a smile :-) So *I* don't worry.... |
