Interesting; sounds like some sort of channel calibration/equalization/training. What were your receiver settings (mode, filter widths, processing)? When I first began listening, my impression was of out-of-band interference from a paging transmitter or trunking public service repeater slowed _way_ down. Michael I already stated the receiver was in AM mode using the 9.5Khz bandwidth. No processing. |

Just kidding. -- Mats I've been uploading audio in ogg for years. http://www.lazygranch.com/red_audio.htm http://www.lazygranch.com/janet_audio.htm While not much of an advantage for mono, ogg is very useful for stereo scanner recording. That is, you record two scanners in real time. MP3 will share the audio between channels, while ogg behaves as if each channel is discrete. I try to use open source standards where possible, i.e. LAME or Ogg versus mp3. FLAC versus whatever crap Apple is pushing lately. |
