Plaaying around with the DX398 I have found
that a "strong" singal is much better then a weak one. I just ran 100' of wire and laid it on the newly fallen snow. Wtih no matching tranformer. (as an aside, antennas work much better if errected in bad weather, in fact the worst the weather the better the performance!). By winding the wire in and out, I have it on a military spool, I found that the DX398 is much happier with a strong signal. I don't have access to equipment to measure the exact signal required, and I don't think the ARRL lab comparison of the DX398 with other portables adressed that issue. And yes my wife is convinced that I am insane. But she willingly helps me with thes odd experiments. At some point I am going to have to errect an antenna "just for her". I am just glad she hasn't grabed one of my R2000s! (My original R2000 is showing it's age, I took it on one too many picnics and I hope to restore it in the near future. The tuning has gotten very touchy and I tend to use it for a dedicated WWV receiver at the moment.) Terry |

"Scott A." wrote in message ... 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. Try turning the RF Gain/ Attenuator down until it sounds like you want it. Makes a lot of difference. 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. |

Gosh am I red faced -- been complaining about PDF for months (years) --
didn't know about the text tool for copying text. Guess it is a case of "When all else fails. Read the ^*^%%* Manual !!! Thanks for the tip Now where is that file I wanted to plagiarize (;-) -- Caveat Lector "Gary Brown" wrote in message . com... 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. Gary K4GPB "Scott A." wrote in message ... 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.) |

It is not just a case of flipping a switch. I haven't had a 398 in several
years but the basics are, switch to sideband mode, set the tuning for lowest posible tuning steps (40 hz in this radio) and use the tuning knob to tune it in. If you can't get it tuned, you are in the wrong sideband. Switch to the other and do it again. Likely, in this part of the spectrum, those pirates are on lower sideband. "Scott A." wrote in message ... I don't quite know what you mean by "tune below it," but I wonder if there's something wrong with my radio. It's always sounded like this in SSB. BTW, I'm in Fort Wayne, IN. Know where they're transmitting from? |

Check again. The 398 is fully ssb capable.

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. -- Telamon Ventura, California |

I read the post and then looked at my radio and then commented on mine without noting the original post had a different number. Dumb. It was a bad model number day for me as I did a similar thing in another post yesterday. -- Telamon Ventura, California |
