Just for the hell of it, and to give this DX-160 one more chance, can anyone
point me at a bandspread tuning tutorial? Is bandspread tuning similar in concept to a vernier by any chance? And, why is it necessary on the DX-160 to use the main tuning to the specific "white crosses" on the dial to use the bandspread tuning dial? |

Set the bandspreda to 0 or 100 as required. Fine tune with the Main tuning. Make this station your bandspread anchor. Using a frequency guide write down known stations and their bandspread indications without moving the main tuning. Do a chart for every band. Your $50 radio will then be perfectly calibrated for SWL. For example 12095 would be your anchor at the top of the 12 MHz band. As you tune down on the bandspread you'll across some powerhouses. Note their actual frequency and their bandspread indication on your chart. Soon you'll be able to guestimate the gaps. |

The bandspread dial is only accurate when the main tuning is set to those white markers. I take it this is your first analog receiver that doesn't have a digital frequency display. You would probably enjoy your DX-160 more if you used a display with it. It can also be used with other analog receivers, in case you get the bug for a real 'boatanchor'. Here's where to get the display. http://www.aade.com/#dfd |

I actually am in contact with the fellow over at AADE, thanx to a pointer
from "lowbander". They say a modification must be made to the 160 to allow for a digital frequency readout to function, so I asked him how much he'd charge to make that mod; haven't heard back yet . . .

It's not a big deal to connect a digital frequency display to the DX-160. It just requires a short length of coax to the main tuning oscillator circuit. If you have the schematic I can suggest the connection location. Do you know how to solder? You could hardwire the display to the receiver but it would be better to install a jack (RCA female phone jack) on the back, so you could unplug the display. This would allow you to use it with another receiver. "HFguy" wrote in message news:qoUag.1748$cl5.1729@trndny07...

I do not know how to solder, and my hands do not sit still well enough to
perform such exacting work; I wind up burning a circular sport 3 inches wide around the target! I would really like to have a digital freq. display on this unit too, but AADE does not do the actual modifications. Oh well, back to my original idea: anyone interested in a DX-160?

From your RR IP address it looks like you're in Ohio, so I'm no help in Florida, but its a simple job. I would add a buffer amplifier to keep the modification from affecting the dial calibration and alignment of the radio, but that is simple, too. BTW I lived in Ohio for 35 years, just below Dayton. -- Service to my country? Been there, Done that, and I've got my DD214 to prove it. Member of DAV #85. Michael A. Terrell Central Florida |

Do you know a tech' or ham' in your area that can do the soldering? It's
really very easy. Just make a hole in the back cover for the RCA jack and run the coax from the jack to the oscillator circuit.

No, don't really know anyone that does such, I only very recently got into
this hobby . . . "HFguy" wrote in message news:Pnwbg.72$zg5.4@trndny04... Do you know a tech' or ham' in your area that can do the soldering? It's really very easy.

How can you be contacted to discuss this further?
