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 |

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. 73 de John, KC2HMZ, KNY2VS Tonawanda, NY, USA TS-450S-AT, DX-394, Wires http://www.kc2hmz.net |

Here's an interesting link to information about the receivers and copies of manuals. http://www.decodesystems.com/dx150.html |

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. :-) |
