You're right. Seems my radio is working fine. I've moved my radio and
hooked up the not-so-great amplified sw antenna I bought at RS about the
same time as the radio. It sounds just fine now. Noisy, but very clear.
Just got done listening to a little story about an acid flashback. I even
sent them an email at the address they broadcast.

btw, I'm planning on building a "broomstick" antenna. I know it's not the
best thing, but it's cheap, easy, and portable. I'm thinking it will bring
broadcasts like this in much better. I can probably even use it with the
amplified antenna.

Thanks for the link. I actually have my original manual. Read it just a
couple nights ago. I was actually suspecting that the radio wasn't working
right, but this is easily the best sounding ssb broadcast I've heard using
this radio. I'm convinced now it works find.

Thanks again.

You should be able to tune it in. I have used my DX398 and have had
no trouble. Try tuning slowly above and below. I am receiving the
6.925 pirate (now Underground radio) in USB, so tune below it.

He is not complaining about picking the signal up but making it
understandable. You can't do this with DX-398. No SSB mode or BFO means
no SSB detection.

ER, you might want to take a look at the DX398 again.
I have mine in front of me and it certainly does have
SSB mode, support for both LSB and USB.
I modified mine to defeat the tuning muting, but
even with that, I just barrowed my wife's stock
DX398 and I can tune it just fine. I prefer the lack
of mute,.
On the lower right front there is a button labled
am/mode. This toggles/steps the radio through
AMLSBUSBAM.
Again, please recheck your "facts".

I still have my DX-398. It is my first portable SW radio. Portable
defined as you can easily hold it in one hand. Unfortunately it does not
have SSB mode or a BFO so you can pick up a SSB transmission but not
demodulate them properly.

It is a great sounding radio for AM transmissions, which is almost all
of the SW program broadcasters. Very few programs are in SSB.

This leave out most of the Hams broadcasting in SSB but some still
broadcast in AM.

Most of the military and utility stuff is SSB.

I believe you're mistaken. The DX-398 does have true usb and lsb. Press
the AM mode button to cycle through them.

Since it is in pdf I can't copy it and don't care to type it, but the
procedure is quite clear for LSB and USB tuning --- see page 25 of the
manual


Sorry about my previous posts. I pulled the radio out and did not see a
BFO or SSB switch on it and I don't recall ever using it for SSB.

When I get some new AA batteries for it I'll have to try the hidden SSB
modes. Didn't think I'd learn a new thing about a radio I have owned and
not used for years.

Used select text in Acrobat Reader to copy text from a pdf file...

When you have located an SSB

station, press AM MODE to receive

the transmission. Repeatedly

press AM MODE to switch between

USB or LSB transmissions (try

LSB for frequencies below 10

MHz or USB for frequencies

above 10 MHz).

4. Set STEP to SLOW then readjust

MANUAL TUNING for maximum

intelligibility.

I have a Radio Shack DX-398 that I bought in '97 or '98. Whenever I try to
listen to anything in either usb or lsb, it sounds sort of like the
chipmunks. The pitch just sounds wrong and unintelligable.

I don't have a lot of experience with swl, so I don't know if this is
normal or not. I would expect normal AM broadcasts to be distorted, but
signals that I'm sure are ssb also sound bad.

(This problem comes to mind now because I was attempting to pick up the
pirate broadcast on 6925 mentioned on this newsgroup just a few minutes
ago, which I'm pretty sure is usb. I can pick it up. I even recognized
the old David Crosby song they were playing. But it's still un-
intelligable.)

That's normal for the DX-398/ATS-909.
