[IRCA] Transistor Radio Shoot-Out
Hi Mark,
Thanks very much for running this detailed test, and posting the
interesting results.
Steve Ratzlaff and I had fun developing the modifications for the
"Sliderized-Filterized SWP," and we are happy that the little 9 kHz-split DX chaser
gave a good account in sensitivity and selectivity.
Your impressions of the relative performance of the other portables follow
my own tests pretty closely, and should provide helpful purchasing
information to interested hobbyists. Thanks again!
73, Gary DeBock

The West Coast DX community has done quite a bit of portable radio
testing lately.
I figured I would make an East Coast contribution with an article
"Transistor Radio Shoot-Out at Menotomy Rocks Park".
This is available at
"http://home.comcast.net/~markwa1ion/TransistorRadioShootout.pdf".
Radios tested were from all size categories from the ultralight to the
big and bulky.
Parameters evaluated in these daytime tests included sensitivity (weak
signal audio recovery), selectivity, and strong-signal handling ability.
Those who have read some of the other reviews out there on the web may
find some similarities with others' findings.
The more of this experimentation by more people from more viewpoints,
the merrier.
