Default FS/ Radio Shack DX 394

Too many radios so the DX 394 needs to find a new home.

This DX 394 has been modified by Lowbander. Lowbander is an ebay
seller who does mods to the DX 394, DX 150, and DX 160 and other
radios. Check out Lowbander's ebay feedback and radios he has for
sale. I can provide a digitial picture of the radio. I can also send
a copy of the ebay web page that contains the complete description
of the radio.

This radio is in excellent shape with great reception on all bands.
Includes manual, documentation of the mods done to the radio, and
telescoping antenna. Here is a descripition of the mods that have
been done to this radio:

1) KIWA FILTER installed in the IF, greatly helps selectivity in the
crowded shortwave bands. It is an awesome Improvement in the Radio!
It reduces interference from adjacent channel bleed over in the AM
shortwave frequencies because the Kiwa has tighter filter skirts!

2) The "Chuff Chuff" noise when fine tuning was stopped with a
simple mod.

3) Keyboard Beeps mod was done to stop the annoying Beeping.

4) Cross talk Mod was done by adding components in the ceramic
filter circuit to reduce interference. This mod greatly reduces the
problems from strong adjacent channel interference or bleed thru
from the filters. This narrows the bandwidth by adding more
capacitors to the circuit around Q13 is the second part of this mod.

5) Noise Blanker Mods improve the radio Noise Blanker on AM and also
make it functional in the SSB and CW reception position. Adding some
resistors and a Schottkey diode in the circuit and adjusting the VR1
control "Greatly Improves the radio!" Completion of this mod is a
significant improvement of the radio!! If you live in an area of
high impulse noise it makes the 394 perform like a much more
expensive receivers costing hundreds of dollars more.

6) Weight added to Main tuning dial makes the radio feel like
a "Real Radio" with a heavy flywheel dial. Approximately 4 oz. of
lead was added to the dial and helps the "Feel " of the dial.

7) RF Gain control mod provides better linearity when adjust gain of
radio. This makes it much more flexible when tuning and listening to
loud or strong SW signals. This mod had a big effect on the radio as
well!

8) AGC mod done to reduce speed of AGC circuit. This makes it easier
to listen to on AM or Sideband. The original manufacturer had a very
fast attack AGC speed. Up and down signals will not pump the audio
sound unnatural now. In ham lingo, the AGC has been modified to
compensate for fast QSB.

9) Audio hiss removed from audio circuit by adding more capacitors
to filter out some of the higher audio frequencies. Thus, this gives
the audio more punch and makes it easier to listen to. It also helps
make up for the cheap built in speaker. An external, Good quality
speaker is also recommended!

10)Hum Reduction- An additional electrolytic capacitor of at least
2200UF has been added the rectifier section, smoothing out the DC
and most importantly to reduce any hum when listening to headphones.
Unmodified DX-394's sing and hum without this key addition.

11)Cabinet Shielding- The top and bottom case of the DX-394 have
been covered on the inside with conductive, aluminum tape to shield
the radio from RF interference. Common interference from nearby
radio stations(Broadcast Shortwave or even Ham and CB), computers,
TV computers monitors is greatly reduced or eliminated in most
cases! The common birdies, heterodynes and spurious radiations will
no longer ruin your reception of desired shortwave signals!.

I'm asking $175 or best offer. UPS ground or USPS Priority Mail
shipping is included in the cost. Will not ship outisde continental US.
I'll accept a money order or personal check, radio will be shipped
after check clears. Postal money order preferred.
