Dx431, I never owned or used the older model 257, but on my new one I did the channel conversion and never did anything else to it and love the overall performance. Lon Tech808 CEF808 N9OSN |

Lon, hows the conversion done? Is it a jumper or removal of a diode? |

Thanx Lon, thats what I wanted to know. It's hard to believe that the 257 had better audio on SSB than the Lincoln. |

I own a 257, pound for pound a GREAT radio. I had Copper's do the channel mod, but I am unable to do it myself. I especially like the memory channels -it remembers frequency AND mode. The Mic is actually a power mic, although the control is inside the mic.

Perfect radio expect it doesn't have the analog meter/needle big faced style. I can talk to anyone I hear. Has features even some of the big radios don't have. mikefromms |

Guys: Am I right, you also can't SCAN just the memoty channels, like the dx-2950 will do, correct? Analog meter would be nice, even if ir was a "Plug in module". Any meter would be nice, LCD readout? |

Great SSB radio. AM is good, but for AM you definitely need a good power mike and also possibly to do the swing modification. On SSB though it's one of the best deals around. I love the preset channel options..the NB works great. The Varible RF power is a must have for running an amp. Wouldn't mind a actual meter or SWR meter built in. Overall great cheap deal. |

Brew..... You have a power mic, just the adjustment is inside the microphone. . Set the modulation according to Lon's direction and you have all the mic you need without adjusting the mic. My only regret is that the mic is so small. At any rate a Power Mic is a cheap addition, if you want one. |

Is there a radio exactly like the 257 that has 1 final or can the unit be turned down to run a palomar 250,as I don't have the dough for a boomer 400 too.Bigbob |

The Magnum 257 has variable power and can be turned down to 1 watt. Now that is as "exactly" as you can get, ;?) |

A mag 257 will run that Palomar perfectly. You can adjust the deadkey on the mag 257 and do a swing mod. You'll deadkey 2 watts and swing 20. Crackerjack...I did try adjusting the stock mike using the internal pot, but I found I get 3-4 watts more swing with my D104. |

That's possible, don't get me wrong. I don't like the mic that comes with it anyway -way too small. I had the modulation adjusted in the radio according to Lon's posted instructions and the stock mic modulated 120% without internal mic adjustment. But it all comes down to what the audio sounds like at the distant end, when I find another mic that sounds better (my D-104 didn't), I hope it is a desk mic. What do the DX reports say about they way the 2 mics sound?

Crackerjack, That is with my voice and a loud Audioooooooooo and showing a smooth wave on the scope with no peaks or spikes. Your voice may be a little different but the radio will still do 100% modulation and sound great with the Stock Mic and no adjustments being made inside the microphone as it did with the 1st Sargant testing it also.

I already sold the Night Eagle. I like the way the stock mic sounds, I just don't like the mic. I have a big hand, and that mic is sooo small, I can't believe that they marketed it like that. Oh, well, it is a great radio. I should have mine back Tuesday. |

Lon's Tune-Up: I was all over the place this morning. Thanks to Lon Tech808. He performed that tune-up (see post above) to my Magnum 257 =and it was a real improvement to an already great radio. He offered before, as a special favor to a fellow Disabled Veteran -and did it free! I put ir off until now. I was excited, of course at a 09:50AM contact with Brazil and Atlanta, I went back to Arkansas, Kansas, Colorado, Tampa, Miami, and Alabama. All USB/LSB barefoot off my STARDUSTER groundplane, with the stock mic. I had Little Rock on AM! Good work, Lon! |

Yankee, Yes, Sam Lewis is the Owner of the RF Limited / Magnum International / MotoComm and Adonis Companies. Sorry but there is no middleman except the distributiors that sell the products to the public such as Copper. Factory to Sam ~ Sam to Copper ~ Copper to Customer. As for the country of manufacturer he has different models manufactured in different countries. Magnum International Magnum International ~ 1-877-624-6869 Our Magnum 257 is labeled MADE IN THE PHILIPPINES Hope this helps, Lon Tech808 CEF808 N9OSN

I talked San Antonio to East Alabama this morning, on AM. I had the guy tuned in LSB and he was rock solid and couldn't tell I was in Side Band. Lon marked my radio so that I know where exactly the carrier should be. Center dead on. I switched to AM, and the thing swings so sweet that it hardly made a difference. My RCI 2950 wouldn't have done that. |

Hope this thread isn't dead. after mod and tune accord to your review. what will this radio swing (PEP) on Low Power (AM)setting? My KL 400 is sitting next to me beging to be instaled. I think the 400 can't handle more than 20w peak input. thanks

Itatorro, The KL calls for Input Power: 1-4 Watts I would suggest you set your Dead Key Power / Input to 2-1/2 to 3 Watts and NO more. If your Watt meter is Wrong you can blow the amp up with your 1st Key up. Remember the KL-400 is a LOW Drive Amplifier. Lon Tech808 CEF808 N9OSN |

Lon: I got my DOSY back, freshly calibrated this week. You set my Mag 257 minimum output to 1.5W. That is where I set it to drive the AMP. I originally thought it was even lower. All I have to do is turn it down all the way. Good deal, and it works fine. Again, you did a fine job on this radio. While the kl-400 is a low drive AMP. it is slightly higher than it's brothers. I run one on a DX-959 set at factory max output of 4 watts (it has been well measured) and it can't be turned any higher -it runs clean and cool. Again, I only run it at level #3. I would not run a kl-300 (etc) that high.

The Magnum 257 is the "Imax 2000" of radios. For a little money you get a lot, and I mean a lot, of radio. If I ever sell mine it will be to make some money to go toward buying the S-9. I still have my doubts as to how the S-9 could be that much better of a radio than the 257. One day I will see for myself. mikefromms |

Harve, Wrongway - CEF #113 and Jaybird_OD CEF #557 are both OTR Driver's and both have the S-9's from Copper and LOVE them and both also run a Single Antenna. Many, many nights we have talked with them in the 65-70 mile range heading to bloomington and after passing through. And we even talked with them on our Copper Trip when we were using our S-45 in the Truck headed to KY. Lon Tech808 CEF808 N9OSN |

Lots of news running around about the cobras 200GTL is supposed to do 100 watts SSB. lots of features, roger beep. no echo. MSRP $299 But no one has got a hold of one yet... everyone is really questioning if these radios can compete with the other exports out there right now..will be interesting to see...mid July we should see them |

When i was a kid in the 70s my base was a cobra29 and a starduster at about 35ft it was fantastic. All stock except had a turner power desk mic that i loved to talk on. I could talk 40 miles on a quiet night. with all the neg comments about new Cobra radios now Do we expect these new 150 and 200 radios to be competeing with S-9 and 95t's.....mabe if they let uniden build them again or someone link RFLimited,,HA ha! I am interested to see. HO! is there a market for old 23chnl cobra 29's? My neighbor has one in his garage that has been sitting there sence the CB Boom in the 70s. I is possible it still works. don't know though. it |

Just waiting to see who is making these new Cobra 10 meter radios. As Cobra went away from Uniden several years ago to have their radios made in China and as of late I have been hearing that Uniden has gone away from the Philippines. Very sad that these two radio giants have done this. Carl CEF-357 |

Not to start a holy war, but.... I really think where the radio is made has very little to do with the quality at the end. My father manages manufacturing of precise components in China and other places. From what I understand chinese work very hard and it's matter of putting good QC process and managing the manufacturing vendor with apporpirate control. It ultimately has to do with how much effort Cobra, Uniden or who ever puts in to managing the outsource vendor. NOT where it's made. Having said that I understand loyality to certain BRANDS or where it is made. Kinda of like how I like dodge truck, rather than furds. Ken. |

I agree Ken. It all comes down to QC, design and the machinery it is produced on. The country and workers have little to do with it. I have seen a few companies that have products produced in China have mucho QC problems. They re-did the manufacturing process and built more modern plants and Wola! Better products with very few failures. Price stayed the same. Chad |

Yankeeboy323, You can Rewire any 4 or 5 Pin mic you have to a 6 pin plug. You ONLY want to use wires #1/2/3 and 5. MICROPHONE INPUT Pin #1 ~ Microphone Audio / White Pin #2 ~ Receive / Black Pin #3 ~ Transmit / Red Pin #4 ~ Down(Up w/22K Ohm Resistor) / Blue Pin #5 ~ Ground / Shield w/yellow sleeve Pin #6 ~ +13.8VDC / Brown} Make sure that NOTHING can come into contact with Pin #6 Hope this help's, Lon Tech808 CEF808 N9OSN |

Mine should be comming in from copper on Monday or Tues. Can't Wait. I had Copper do the mode because I am transfering soon and won't have time to do it. Will be using it with a Lighter adapter until i get settled in VA. m257 is the only reasonable choice especially if you were considering the 11m only SSB radios.

Yankeeboy. You got the CEF member ship right after me ! I'm 598 ! Getting 600 woulda been sweet. Anyway, I got my 257 last friday as well. Installed it the same day. Works well. Seems to be picking up much more RX than with cobra 29 I replaced it with. Just one words of caution. 257 seems to be more sensitive to noise, so install in directly to the battery, if you are going mobile ! After doing this, I get lot less noise, but still more than my cobra. cya l8r. Ken.

Exactly...Magnum is very sensitive to engine noise and electrical interference...run it directly to the battery...& you'll probably want to turn on the NB/ANL feature to quiet it down. Doesn't really lower incoming signals so don't worry about using the ANL/NB. |

KennJen & Brewdirect, If you get the Magnum power cord filter offered thru Copper that will also help with the engine noise. I have both the new 257 and the old style 257 and I use the filter on both and it works great. And you can't beat the price for it either.
