DX-150 Bandspread Dial question
 

Did the DX-150 by Radio Shack have a calibrated bandspread dial for
International Shortwave Bands? I believe the DX-150A, DX150B, and DX-160
did not.

John, the bandspread control on these receivers was calibrated for the
ham bands. I knew a guy back in the early 70s who had a novice ticket
and one of these was his primary station receiver, I remember watching
him sit there working guys on CW using it. He had dumped a Heathkit
receiver from the same era in favor of a DX-150A.

Others may disagree, of course, but I believe that the 150A was the
best version out of the bunch. It had the FET front end that
eliminated the crosstalk the original 150 (which had bipolar
transistors in the front end) suffered from. The 150B and the 160 used
a single IC and seemed to hiss a lot more than the 150A, and the 160
used cheap plastic knobs instead of the solid metal ones on the 150A.
Also, on the 150A the main tuning capacitor's shock-mounted on rubber
standoffs, on the other models it's bolted directly to the chassis.

The audio quality wasn't that great on any of these but if you used
headphones there was no problem - and it's tough to beat the
sensitivity on these radios.

The 150b had a ham bandspread dial. Here's an interesting link to
information about the receivers and copies of manuals.

JK - DX-150 Radio with 'bipolar transistors' . . .

Did the Radio required Medication ?

Yes, darn it, each transistor required a spoonful of medicine every
four hours of operation time, and I still blame that tiny little
bleeping spoon for ruining my eyesight forever. :-)
