I'm going to buy a Ranger 2995DX from Copper electronics. I need information? After I have Copper install the 11 meter conversion, and peak and tune. What about the Channel Guard Bleed over Filter? Will Copper install the filter for me? How well does it work on the Ranger 2995 DX? I have read nothing but good reports about this filter. Will the small surface mount technology of the board be a problem? I’ve been in the CB radio for a long time and fell that this filter will be a plus. Will the Channel Guard Filter Work with the broad banded nature of the Ranger 2995 DX? Or just in and around 11 meter band? Thanks from Springfield, Ohio. |

Bassbug,
As an Owner of the 2995DX and also installing the Channel Guard for many years now (well over 500 installed).
I have not found that I needed the Channel Guard installed in the 2995DX.
Yes, they can be installed in the SMD Boards like the 2950DX, 2970DX and 2995DX but it is Highly Recommended that it be done by an Experienced Tech with experience with the SMD Boards.
Copper will soon have the Channel Guards on Hand and I will be working with the Copper Tech at Copper on installation's and tip's.
Hope this help's.

Channel guards work on the I.F.frequency which does not change like the tx/rx frequency. |

there is a shield over the area on the 2950dx where the cg would go. this shield will need to be modified also b4 the cg can be installed. |

Tech8541. The shield over the area where the Channel Guard would go. You said 2950DX. You meant to say 2995DX? Right? That's the radio I want to buy from Copper. I don't always type what I mean to type. I'm trying to do my homework on the radio. I want everything done before I buy the radio. Because I hang on to a radio for life. I don't buy and sell. Thank you, and thanks for your help. |

Bigbob, You said the Channel guards work on the I.F.frequency which does not change like the tx/rx frequency. That was my thought as well. That would mean the the Channel Guard Would work pretty much for the 11 meters not on 10 and 12 meters bands. The receve would go dead when you moved away from the band. How tight is this Channel Guard Filter? Is this filter not for the Ranger 2995DX? How about any thought from the Techs? Thanks, Bassbug. |

Fits all PLL or crystal CB transceivers that use a 455 KHz, 7.8 MHz, or 10.695 MHz IF frequency.* Installs in minutes with common tools and no special knowledge. Works on AM, FM, and SSB.
FEATURES:
· Provides up to 100 dB adjacent-channel rejection. This is much better than most CBs, which typically specify only –40 dB to –60 dB. A factor of "100 dB" means that any signal outside the normal 10 KHz CB channel spacing is reduced in strength by a factor of 10 billion from channel center. Turn your ordinary rig into a hot performer!
· No reduction in receiver sensitivity. In fact, the CHANNEL GUARD adds one stage of amplification at the most critical point—right in between IF filtering stages. You may even hear those weak signals that you missed before.
· Quality components used. Each CHANNEL GUARD is hand-made and thoroughly checked against a powerful 30,000 µV modulated test signal. You get a 1-Year Warranty when properly installed. Just solder it in and forget it!
*Most CBs use the IF frequencies shown above. The dual-conversion SSB rigs with a 455 KHz IF use that frequency only for AM or FM; otherwise nearly all SSB types are 7.8 MHz or 10.695 MHz. The AM-only or AM/FM-only radios almost always use a 455 KHz IF. If in doubt, send us a large stamped SASE with the exact model and we can advise you which version to order.
SPECIAL NOTE:
Our 10.695 MHz filter really cleans up all the Uniden & Cybernet “export” radios, and all
the CB lookalikes (HR2510/HR2600, Cherokee, Connex, Eagle, Galaxy, Ham Int'l, Magnum, Mirage, Northstar, Ranger/RCI, Superstar, TriStar, etc.) And in every mode!
My other thought's are posted above on the Channel Guard.
Hope this helps.

bassbug, all of the 29xxdx radios use the same main board, so any of them will need this modification to the shield.
the 1st paragraph of tech808's post above that talks about 'installing in minutes and no need for special tools' was written before the 29xxdx radios came into existence. you need some special tools to install the cg in these radios.
if i had the time,i'd get with mr. franklin and see if he/we could look into an smt version for these radios. the xtals are now made, and so are the rest of the components. this would then fit under the shield, so that it would not have to be cut. |

In your radio,your I.F.is the same 10,11,12 meters,the c.guard will work. |

Thanks, Lon tech808, Tech8541 and Big bob. I think I will only have Copper do the 11 meter conversion. You guys have been a lot of help. Thank you. |
