RadioShack DX160 Modifications - Part I

I created this video with the KZbin Video Editor ( / editor )

[@extremeedison]

The Realistic DX-160 radio has a dissimilar metal problem on the tuning printed circuit board with the rivets that connect the top side printed circuit to the printed circuit on the bottom side of the PC board. Resoldering is not sufficient, the fix is to solder jumper wires on the top side of the board to replace the connection made by the printed circuit on the bottom side. Shining a bright light through the bottom of the board shows clearly where to solder the jumper wires on the top side. This is the RF amp and Local Oscillator circuit so it will require alignment. Operation without repair may be intermittent.

Thanks for pointing that out. I'll look the next time I get it apart.

Around 8:00 , you should try: *DeoxIt* *D5* & *DeoxIt* *Gold* The Neon is an *NE-2* or *NE-2H*

These machines are fantastic. Did the mod and it give a much bigger signal on all bands. In the second edition of this beauty there is a resistor (R62, 33kOhm) in the first Bband transformer. remove that and you will hear much more on the B band. For the ant trimmer C there is a fixed Cap (C77 100pF). When you short this fixed cap, the antenna tuning will be more effective. Great receiver, I have a Kenwood QR666 and this bad boy is much better! I sold my Kenwood, yaeshu frg7700, my intermerc ham2, my realistic dx200 cause this is a better performer.

Where's the schematics to ALL of the MODs?

[@jjarratt]

What type of neon bulb did you use. The voltage rating can be different for them. Thanks

[@michaelbradford2816]

I used a very standard replacement neon. These usually run 90-110v just fine.

NE2

There's quite a lot about that on the Internet. I also have the second version, just Google it.
