[Elecraft] K3 as a SW receiver

[Gordon & Lois Duff]

In response to Tom’s question, I offer the following, which may be
controversial. But, the probably shouldn’t be as the differences I noted
were not major. 

 

I have 4 radios that I provided with the same antenna at the same time. I
tuned in a strong AM shortwave station and then a weak AM shortwave station.
I feed the all the audios into the same mixer – amplifier – speaker chain.
I used the mixer to switch between radios to compare how the audio sounded.
I used my 38 year old daughter as the judge of how the radios sounded.  She
did not know which radio was which, she just reported did “A” sound better
than “B”.  We tested 4 computer controlled radios – the results on sound,
best to worst (her preference) were K3, then TT331 (pretty much a RX340),
AOR7030+, QS1R.  I would rate the 331 lower, but again, these four radios
are very close.

 

I love the QS1R panadapter, and for the money it more than holds its own.
But,  it requires some audio attachments and a computer (so does the 331).
