The Perseus actually out performs the K3 receiver regardless of what
the recent ARRL test reports. I agree that the ARRL needs to come up
with valid tests to evaluate real world performance of digital
receivers such as the Perseus, ADT-200A, and QS1R.
-------------------------------------------------------------
Perhaps some test similar to the wideband 'noise loading' tests performed on
multichannel microwave systems would be useful. A problem that might arise
is IMD generated by the test equipment's bandstop filter used to prevent
noise input within the tested receiver's ultimate passband.
