Default bandspread tuning tutorial?

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?

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.

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?

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.
