i bought my 2950dx from copper and had them mod it for me. its easy to do but what the heck rite.
it will go 24-32 mhz and should do 30-35 dosey watts pep
you can also set it up to cover 21-29.699mhz if you perfur. or 23 ch only and 7mhz only. ive not tryed the 7mhz mod though. all others do work. |

bullet the one i had worked fine on 24.95 and 28.450 I ve heard of the 21 meg mod but never tried it. Now no one cares if you play 27.4-27.999
and just a few are on 26.0 to 26.60 HOWEVER i would be carefull above 30 you will find fire departments still use 32-36 ....... |

bruce,
i set mine up to 21-29.6999 i never heard enuff traffic above 29.69 to warrent using those freqs to listen to so i moved it lower so listen thier instead.
its very rare im off the normal band, i visit ch11 22 27 28 and once in a blue moon 27.475 lsb.
when i built my beam i made it for gain mostly and f/b its not wide banded enuff to cover alot of freqs (26.8-27.8) so i keep it were it was designed at.(norm 40)
my colinear covers a huge band width but i talk mostly to locals, some skip and ground wave at nite.
i know its funny, got all those freqs and i use less than 6 of them. |

Hey Bullet what up?
Ive heard of some 2950dx's going down to 21 i know someone sold a kit to do that...... HOWEVER I doubt that radio will work well at 21 mhz I would be willing to bet its straining the bandwith of the transmitter to the limits and if i was you i would see what the transmitter lookes like on a spectrum analizer. As for 29.70 and up this is not a place to be freebanding ... between 30-45 mhz are a number of fire frequencys I know several in the 33-35 range are in wide use. My DR-03 alinco will receive up there and with it hooked to a outside antenna you can hear them when the band is open ...... As a friendly warning if your freebanding BEWHERE... stick to 25-28 its much safer. |

bruce,
how ya doing.
they will tx and rx fine from 21-30 mhz,no kit needed at all(besides the pigtail it came with from factory and a shorting stub). anything outside of this freq range then the radio needs to be reajusted.
im currious as why you comment on what freqs i can get away with transmitting on. when my post above states the channels i run. lol
i get away with it from 26.9050-27.5550 this is my own personal limit that i feel is reasonable and wont interfear with anyone.
with that said, its "very rare" im ever off the normal 40 channels.
as 90% of my radio time is spent on ch 22,27,28 and the rest is on ch 6, ch 11, and ch 26. so i dont feel a big need to free band.
but if i venture out the above is my limit i tx on. i listen to what ever i can cover. "hince the reason for the freq mod to lower limit as i never hear anything up in this area above 29 mhz ham traffic."
in my opinion i think its stupid to transmitt on gov/ham freqs but thats just me and how i do things here.
i dont have a problem with freebanders unless thier interfearing on a emergency band were someone could be indangered from it,or known ham freqs.
thier are some gov freqs that i know they hang out on but when i was in commo we were never interfeared with from freebanding cbers,hams yes we would have ham operators try to talk to us from time to time.
i even had one try to run us off our net once,not realizing i guess we were using the freq to conduct our net.lol he quickly learned were the big green machine sits on the food chain.
next summer will make 30 years ive been in the radio hobby. and ive learned alot in school,in arrl books and along the way. and were and were not to talk was one lesson learned many years ago.
i like to learn from others mistakes a trait i aquired from being a middle child i guess. |

I did not mean to sound in any way like i missunderstood that your use of the radio was restricted to the frequencys you listed only comminting on what your radio can go too although you wisely aranged yours in the down direction.
The comment was ment to inform others too 30-45 mhz is still used by fire departments and this in not widely known.... just passing good info along.
As I know you know interfering with them even unintenaly will get you in big trouble realy quick. Many think its cool to be on 33 mhz i hear them PEOPLE THIS IS DUMB ! As for 21 mhz cool the only concern is pulling the PLL that far but if it works cool very cool your all set for 15 a great band. Well looks like your getting a good bang for your buck on that radio!

bruce,
that fine,
i hope you didnt think i was up set, i just wanted to be sure you knew i dont tx in no man's land thats all.
i dont think our local fire dept's use anything that low around here anymore,ill ask my cousin he a big wig in the fire dept in hanover and see what they run. im thinking it over 100mhz ? cant remember!
i dont hear much around hear on those 30-50 mhz freqs on my scanner or radio BUT its still wise to stay off them as you said.
man id hate to think that a emergency responder could not get to a victom because i wanted to talk on the radio. that would be a hard thing to live with.. imagine if that was a family member in need or a good friend.
and thats not far fetched concidering that youd be tearing up your own local area the most!
i totally agree with you bruce that is a dumb thing to do. hopefully you can bring them to see the light and how they could put someone in harms way by doing "thier thing" there.
have a great day Mr bruce

Ok bullet no i thought i simply was not clear.
Intresting that thoes LBVHF frequencys are still in use but if your out west and need to cover a large range thats the place to be.... it would make sense.
OK FREEBANDERS! STAY off ( most know this )
CIVIL AIR 26.600-26.650,
12 meters 24.9 - 25.0,
10 meters 28.0-29.7
and anything over 30MHZ PUBLIC SAFETY
and your chances of getting caught are near ZERO.

Bullett...How on earth can you mod it to go down that far? My 2950 dx only goes from 24mhz-32mhz!?!?!?!?! |

assulter,
its very easy!
open the radio's bottom cover with the front to you,install a shorting stub on the two pins on the right of the front display and your done!
like how you used to get more channels out of the older 2950's with the 13z main boards.
play thier with that stub and you see the 23ch position and 7 mhz coverage as well.
i dont think it will work well on 7 though but then again i never tried to key up either! |

ya thier the same shorting stubs that go on the back of the hard drives.
you can hard wire them if need be, i thought of doing this with micro switches so i could change on the fly.
i just didnt want to drill holes yet its still like new and i just cant bring my self to do it yet..lol |

Bruce,
When you say the following, I have a question. Stupid as it may be. This is a copy and paste of your post a while back.
OK FREEBANDERS! STAY off ( most know this )
CIVIL AIR 26.600-26.650,
12 meters 24.9 - 25.0,
10 meters 28.0-29.7
and anything over 30MHZ PUBLIC SAFETY
and your chances of getting caught are near ZERO.
My question is this,
CIVIL AIR 26.600-26.650,
This Is on a 11 meter CB radio right. Cause my CB has been modified for extra freqs. And I can float a few of those channels like 26.695-26.965 I hear a lot of foriegn country chatter on these freqs. But am I at risk? I mean I fully understand it is illegal to use a CB radio that has been altered to do ANYTHING other than the standard 40. But was just curious. Thanks |
Bruce

1st the 2950dx is a HAM radio TRUE 99% are moded to cb but look for a tag on the radio and see if it says accepted for part 95? You have NO right outside the 40 channels. Certian frequencys ARE in use and you will be heard. Most freebanders know well that you stay off the ham bands and CAP and the TV link frequencys. the FCC IS rounding up people who stray into the ham bands 28.0-28.1 is cw ONLY so if you on SSB you stand out REALY WELL. BEWARE of thoes who tell you otherwise just go check http://www.arrl.org and go look at fcc inforcement it is going on even though it is at a limited level.

Just a note: the 2950dx, when modified to cover 21 to 30MHz, can be easily expanded even farther to cover 18.625 to 36.1MHz. With very little VCO readjustment, it will key-up with a stable carrier from 20.0 to 30.0MHz-the functional limmits of the tranceiver. The expansion is done by the use of the front keypad. |

Hey Bullet,
With your radio modified to tx @ rx from 21-30 Mhz, does the repeater shifts still work? |

With a good peak and tune, what kind of power output can I expect to see from a 2950DX on AM and SSB? |

Usually about 35 watts. You can get them to go higher, but often at the expense of clarity. |

When you install the C.b.Module,on the 27.000mhz
I see 8-watts A.M. S.S.B 12-watts. On 29.650mhz
I see 10-wattsA.M. s.s.b. 25-watts. on 21.000
I see 10-watts and a.m. is clear as a bell... |

I have seen them tuned to do nearly 50w on ssb but at the expense of finals. Johhn....if yours is only doing 12w on 27 mhz you need an alignment. Bog stock a 2950 should punch around 25w.
