bandspread tuning tutorial?
 
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?

Find a station at either end of the band of interest. 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.

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.

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.

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.

Real Radios are the old tube type analog Radios.They have knobs and
analog dials on them.They DX much better than anything else.The have
character and chirisma that NO digital/transistor so-called ''radio''
can ever touch.

Go buy a good electric soldering iron,get a new stainless steel brush
too.(it looks like a toothbrush) Get some pieces of scrap wire and
practice soldering.Your local area libraries probally have some books on
the subjet too.Soldering is really very simple and easy to do.Usually,I
use an old electric wood burning tool/thingy to solder,because I like it
much better.

Everybody (except Collins receiver owners) used to have a crystal
calibrator, a little black metal box with a vacuum tube on top,
that put out a signal every 100 kHz (100 kc in those days). You'd
set the bandspread to 0 and tune the main tuning until your 100 kHz
signal was heard, the idea being that the main tuning was accurate
enough to distinguish 100 kHz frequencies so you got the right one.

Then tune with the bandspread and take the frequencies off it as
offsets from the main tuning frequencies. That is, the bandspread
does the part below 100 kHz and the main tuning does the part above
100 kHz, in the constructed frequency.

You'd either leave the receiver on, or recalibrate as it drifted,
as you use it.

If you know a station's frequency, you set the bandspread to the
100 kHz part and tune the main tuning to hear the station, and then
that calibrates the receiver instead of the crystal calibrator.

Basically listening was partly calibrating the receiver and partly
tuning for stations, if you were interested in what frequency you
were hearing.

I'm at a loss as to why in the age of digital radios one would buy an
analog radio only to go to the added expense of a digital display. Why
don't you enjoy the 160 for what it is and not try to make it something
that it can never become. We all enjoy the point and click accuracy
and speed of keypads and up/down tuning keys on digital radios. The
160 will never be able to come close to competing with that. Just use
the 160 radio in the way it was designed: Scanning the bands by
listening as much as glancing at the analog scales.

having bandspread tuning, then wanting to sell it because "she" has

make it like all the other digital radios is beyond silly and wearing

really it just seems like the guy (a bit different that is seems to be
a gal inthis case) that always has to the latest wizzbag radio (and
that can be be nice to be around if they also have the budget to keep
buying them) and then fools with awhile then more or discards them
(glaning around the shack at a few radios that were the very latest in
wizzband)

in that lisa hardly seem anything but slightly novel

Yes. When we use terms like ''harsh reality'' describe someone's
