[TenTec] DSP filtering Negative Feelings

[Jack, W7EJJ]

Hi Carl:
    I agree with you after my 50 years of ham radio there is nothing
compared to DSP.
    What sold me on it was a JRC NRD-545 receiver I purchased about a year
ago. That has full DSP with 40 bit processing and is the most awesome
receiver I have ever operated.
    This receiver is what sold me on the Jupiter and by the way the Jupiter
receiver holds it's own with the NRD-545.
