Operating Modes : Weak Signal
  • Weak Signals - Reduce volume to reduce noise - This article discusses how volume reduction can help in the reception of weak signals by reducing the noise level. It is commonly known that reducing the volume also reduces the background noise, and especially in the reception of weak digital signals it can be beneficial

Radio Equipment : HF Transceivers : Yaesu FT-1000MP Radio Equipment : HF Transceivers : Yaesu FT-817 Software : Legacy Systems : MS DOS
  • DSPBOX - DOS Freeware, DSPBOX is an attempt to code the Texas Instruments DSK 'C50 in such a way to make it behave like a commercial DSP noise reduction unit, like the NIR-12, the TimeWave 599+ and others. Not only the noise reduction function has been implemented, but automatic notch, AGC and Band Pass have as well.
