What changes have been made and what freq. will the DX cover?
Thanks. |

I believe the old version covered 26 to 30 Mhz, While the new version covers 24 to 32 Mhz. The DX version also uses surface mount technology, which in my opinion makes for a more durable radio. But, it does make it more difficult to work on. (Very small components.) I have a 2950 DX and have been very pleased with it. Oh yes, the old version had an orange display, where the DX version has green. |

Additionally the new DX model uses low-level AM modulation where the original uses high level, that means the new will not quite have that AM "punch" or loudness as the original. The DX is geared more for SSB and is a far superior rig in most cases. |

Better take another look at the 2950 DX schematic... the dc to the driver and finals are still modulated - high level modulation.

Ahhh.. But how do you modify one of the rigs sold by the ham retailers to do 11 meters? The 2950DX radios sold by Copper are easy (plug and play). However, the 2950DX radios sold by AES and HRO are not so easy. Has anyone figured out how to do this yet?
I bought a 2950 DX when they first came out and were not available from Copper as yet. |

conversion of the "unmodifiable" 2950dx to 11 mtrs requires a freq exp module and wiring directions to connect the module to the micro-processor board. |

There is also something else no one has seen yet... 21-32mhz is what my 2950dx will do.. but i haven't figured out how to allign it under 24 mhz yet....The way i found this is shourting out diffrent points on the post as normaly would be done for the mods on these radios..Neato.. i am useing a smt switch because when i go below 24 i need to click switch down.. go above 29.6999 i need switch up.. Sure is interesting |

Talk about interesting, do you want to go down to 20MHz on that DX? After you have the module installed, you can trick it into going to ANY frequency between 18.6251 and 36.1049MHz! This involves a litle math but you can do it. You first program the split function...for our example, we will use 6.965MHz. After this is programmed, leave the split funtion in "-split". Next press [MAN] to get to the CB band and dial in channel 1. Press the mic-key momentarily and notice the "buzz" from the radio (because the split function is still active). Press [MAN] and BINGO!...20.000MHz....26.965 minus 6.965 =20.000...to transmit, get out of the "split" mode. You can't save the new frequency to a memory nor can you move off of it without defaulting to the stock band-ends...Enjoy! |

That's kinda like the old Ranger 3500. By punching in a series of commands you can fool the processor into starting scan at 26.000 on go on down. It's just for receiving, don't think they will TX with the scan running. |

I think some of the older Mirage 2950s could be tricked that way as the DX also...that's where I got the idea and it worked! If you adjust the DX band width, you can transmit from 20MHz to 29.9MHz on frequency and with some wattage (with the proper antenna of course). |

WOW Inspector... this is wonderfull 18.6251-36.1049mhz... Tottaly neat....Mine is getting re-aligned as we speak for the 21-32 mhz..Tried your suggestion with other radio and it works...The radio however says im transmitting when im not but i can receive just fine..Guess i need to re-align again....Wonderful Inspector. keep up the good work.. I can't wait to see the future for the 2950dx.. should be great when all the secrets come in the open... |

i decided to get brave and try something with my 2970dx. with the front of the radio facing you, you will see a pad with about six things labeled in a line, with the bottom one reading mod o/p. to the left of that is a small bead connected to that pad. i assumed mod o/p to mean mod output. i crushed the bead to disconnect it from the circuit and put a small blob of silicone to cover it up and now the radio puts out 100% modulation according to my dosey meter. the best it showed on the meter before was 50%. it was a chancey thing to try but it works great .brad. |
