The new CBS1000 arrived from Copper today. Nice looking radio.
BUT-
Modulation is VERY low, even with the DM-452 cranked all the way up. Puts out only 2-3W avg. on SSB, 3-4W on AM, depeding on the channel.
Locals 6-8 miles distant who are used to me booming in on my $15 Sears Ebay special can barely make me out on this radio, even into a 2 element quad pointed right at them.
Receiver is stingy, signals that are S7-9 on a Sears and Cobra mobile in the shack and same antenna are S2-3 in an A-B comparison.
This one's going back.

It was never stated whether these readings were with stock radio or what PEP was. Also it was never stated what SEARS RADIO was doing and whether it was stock.

Maybe one at random needs to be tested and see it it does the same .........

Sounds like it could use a tune up / alignment? |

What I'm wondering is could the ELECTRONIC SWITCHING be bad if so it would be lossy on both TX and RX and would explane why the set dosn't work right ..... |

Even most of the cheapest of radios can get out 8 miles on a beam!
I would definatley send it back to NorthPoint for Warranty Repair / troubleshoot.

i agree that the radio needs an alignment.
i bet that if the radio had channels put into it; the you would find the radio aligned for 28mhz, and probably not that well at that.
get the service manual and do the tune up yourself, i think you will have a long wait to get it back from warranty service.
only after it has a complete alignment for CB freqs. will we be able to tell if its any good or not.
my guess is its a pretty radio that should be very easy to add lots of channels to, that has good enough modulation on TX and a bit of a noisy receiver on RX.
probably not too good on the adjacent channel rejection, etc...
good luck,

For some reason, they come with the SSB ALC turned way down [probably so you can safely use a amp.] Just remove the top cover, find RV14 pot at the rear of the main board and adjust for full power on SSB,It will do way over the rated 12 watt peak depending on your mic. AM modulation is RV5 and AM carrier is RV4. Cutting the ALC limiter is not recommended.
This is the same radio as the Cherokee CBS- 1000 so you can find complete mod and tune up information in the Modification List to the left of the form here under Tools. |

405 is probably right---you might just need to tweak on the ALC and AMC pots a little. I had a Roadpro Titan II that is very similar to the CBS 1000 under the hood, and it needed to be touched up a bit. It was only doing 6 watts on SSB and only 50 percent modulation on AM. I set it to 12 watts SSB and adjusted the deadkey and AMC for 2 watt carrier and 8 watts of swing. I ran it with a KLV-550, and it rocked! |

The roadpro-titan2 is the same as a 257 only with one output.
UNLESS you have good test equiptment I would leave well enough alone. tweeking pots is not always a good thing. MEASURED out of the box it was good for .19UV fm and ran about 10 watts .... 4 on am and was CLEAN |

My Northpoint CBS-1000 came with the same low power on sideband and low mod on AM. As mentioned in my previous post, it is very easy to peak the AM modulation and SSB power. DO NOT max these pots out, but just bring them up to reasonable levels so that your SSB transmit is not garbled and AM is not distorted. Mine performs well! Very nice rig. |

yeah but why cant it just be correct right from the box? why should you have to mess with a brand new radio just to make it work? |

Applejack,
You are correct but the Manufacturer cannot check every radio that comes off of the assembly line.
The manufacturing plant will send the manufacturer several models to check for specifications before final assembly approval is approved.
Then things can change at the assembly plant from run to run.
Northpoint realizes this can happen and includes the following statement in the ad should any problems arise to help Northpoint customers with any problems they may have or that may arise.
Warranty Returns will be shipped back directly to NorthPoint by customer.
This also prevents the distributors from opening or testing each individual radio which would then make it a Used Radio and it could not be sold as a NEW Product and would void the Factory Warranty.
Hope this help's,
Lon

Hi 1861. I have compared the receive to my Galaxy DX959 and it is a little bit hotter. More like my Magnum 257. |

I have a Cherokee CBS-1000, it was low on mod and power new out of the box. With a simple adjust from Coppers Mod List, the little radio that could, CAN now. A D104 on the puppy and she's loud and proud as anything else.

The Cherokee CBS-1000 is a nice basic radio - nothing fancy. The modulation on them has never been great compared to a Washington or Cobra 2000. Compared to most other SSB base radios they are a little light on transmit watts and audio. The Northpoint is basically the same thing.
They work fine as a basic SSB radio, but I think people need to know that a Galaxy 2547 or Ranger 696F would blow the socks off of one.
There's a reason they have a lower price point than many of the other SSB bases. But it's nice that at least there is new SSB base that is in the affordable range even if it isn't the strongest of the bunch.

well i have an ebay bought northpoint cbs 1000. had it about a month and like it fine. push power button and emg/19 button at same time and its good to go from 25.165 to 29.655. talked to 0995 in am net today. some have claimed low audio when talking to me but i have a d-104 handy for it if needed. was already modded when i got it and have had zero trouble with it. i currently have saved searches for another one in ebay. my washington is still my favorite radio but this one is next in line. applejacj #174 in central ohio
