[VHFcontesting] SDR1000 vs 6m xvtr

[Anthony Rick]

If you like the ICOMs otherwise, you may want to consider the INRAD roofing
filter upgrade.  I don't have any personal experience with this modification
but the spectrum sweep on their site shows a pretty dramatic improvement.  I
suspect this would improve NB performance as well.
