Hi, I'm putting together a base unit and need some advise. What would be a better base a 2995dx only or a President Lincoln with maybe a Magnaforce 350 amp. Lincoln peaked and tuned $350 plus amp or 2995dx about $600. Please give pros and cons. Thanks Nick |

go with the Lincoln, forget the amp !!! The prices all look high. |

The Lincoln I've heared has problems right out of the box,however I own a 2995,what a fantastic radio.

Get the 2995!!!!!!!
Then get a KLV 1000P and a set of moonraker beams and a 40' tower and rule the airwaves!!!!!!! |

Do you guys have the fan kits installed on the 2995dx? Copper does not install them and I'm worried about the radio over heating and breaking down. This is my only concern about this radio. The 2995dx is the one I really want, just worried. Thanks for replies Nick |

Hitech,
The Fan Kit is a MUST HAVE!
This radio gets very warm and the Fan Kit works Great.
As for mounting the Fan kit it is VERY SIMPLE on the 2995DX.
All you need is a Phillips Screwdriver.
Remove cover from over Finals on Back, Use the Screws that come with the Fan Kit, Mount the Fan Kit and Put the screws in and PLUG the Power cord into the back of radio.
That's it takes less than 2 minutes.
I have been running the 2995DX w/Fan Kit for about a year now and it is the BEST BASE going.
Hope this helps.
Lon

As in all things the way to make a good decision is to put it down on paper.
To begin let us put down some theoretical ground rules. Rule 1 you both have the same kind of antenna. Rule 2 you both have the antenna at the same height. Lastly rule 3 both antennas are tuned to half decent efficiency.
Say you get just the good radio with a good receiver first. You start to transmit and station X hears you at a 3 S unit. He transmits to you. You will probably hear them because they are running at least equal to your power (provided neither one of you has interference). Now the meter may not bend into the red but you could still carry on a conversation.
Now let us take the radio amp case. You call out for any station using your amp and that same station X hears you but this time at an S 8 or S 9. Sure you can chat very well. HOWEVER Joe Schmo 30 miles farther away hears you at an S 3 as well. Will you hear Joe Schmoe when he tries to make contact with you? Perhaps, but ONLY if ol Joe Schmoe has an amp as big as yours. If he is running only 4 watts he can forget trying to talk to you and you to him. Ol Joe S will have to compensate for the extra distance by running his amp.
So in a nutshell. A big amp lets you reach out farther but it also limits those whome you can effectively reach. You can talk to everyone close in with no problems but the farther out your signal travels the greater also is the power required for that reply person to speak/reply to you. And with 4 watts you can reach everyone close in anyway.
NOW what does help even the score a little is an amp with a built in preamp for input signals. At least the preamp allows you to compensate a bit for the lower power signal inputs so the other stations "Sound" like they are running little amps.
I all boils down to: what do you feel more comfortable with. A fine receiver/radio with nice audio and a good receiver or an average receiver with a little extra help.
Personal experience, in both the fields of CB and Ham, I favor the better receiver over the extra power. But then I like cottage cheese, cabbage, spinich, eggplant and squash. :-o :-) |

de, in your example the amp will work if Joe Schmo has an S7 noise level at his end and if you don't have a high noise level at your radio.
He hears your S8 signal due to the amp and you can still hear his un-amplified signal because you may not have as high of a noise level. |

Actually Kraig...
In the case you presented as reflected by my original presentation Joe S would not hear me at all. Remember in the original case my signal would be only S3 under good circumstances so if he had noise of an S7 then he would not hear me at all. And given that I would have to multiply my power output 4 times over for every S unit gained I whould have to have one pretty big amp to make him hear me with ground wave.
However I will go with your flow and say he did hear me, but barely over the noise. And believe me I do know what you are talking about. Unless my amp had a very good preamp to it I probably would not hear him. Remeber a couple of things about preamps. They amplify the signals that are there. They do not produce them, signals of certain purity and strength must be there to begin with for a preamp to perform well. And they can only amplify just so much. The more you multiply without a digital system to clean up the noise the more you also amplify any distortion as well the signals you wish to amplify. HMMM think, you triple the volume of a friend in conversation in a crowded room with people talking all over the place. While you may triple your friends voice you also triple the voices of those around them in equal proportions as well.
But your case cannot even exist. Wihout going into the math, every signal decreases in strength as it leaves the transmitting antenna. I am sure that you noted this as you drive down the highway. Your buddys signal drops off progressively as you drive away from him/her. So if ol Joe is farther away from me than the person I am talking to then his receive signal strength is significantly less. Remember signal strength never increases with distance in line of sight or ground wave communications.
What you are making ref to by the way is skip. And skip is a temporary thing, here now and gone a minute from now. Ground wave communications is what the fun part is about. Talking to your buds day in and day out. |

If one is starting a bse setup,,,begin with research for the best antenna system that you can buy. This is the most critical part of your station. Without a very good antenna system, all the above hype and and hoopla will be second rate.
Next as DE says, get a radio with good recieve. If you can't hear them, you can't talk to them.
Lastly, with the above (good antenna system, good radio)an amp would be a nice addition, but will create logistical problems if not set up right (interferance to others).
It has taken me several years to acquire the needed parts and pieces for what I feel is a very good station, although not top shelf in my estimation.
What ever you do, enjoy the hobby.

In my sitation i prefer a good receiver and a good beam like a moonraker or the like. Ive been able to talk well over 60 miles local with just a straight radio and my beams and have had no problems. I have a helper but i very seldom if ever need it. The radio usually does the job well enough i dont need the power..
Rule i use is "If you cant hear them you cant work them"!!!! |
