Pat,or anyone else out there,,,advice on if the magnum s9 /40 watt model will work well with a fatboy 1x2,,,,i cant go any bigger on the amp for the base,,,im guessing with a 1 or 2 watt dead key i should be good to go ???? thanx in advance |

the 1x2 probably works best 2 watts dead key, 8-12 swing. you'd have to make sure the S9 adjusts that low, turn the mic gain down to nothing & it'll probably work. overkill for an amp with a driver. |

Thanks for the reply Pat,,,, i got off the phone with magnum today,,,they said copper will recieve the s9's by the end of the week,copper is currently out of stock,as i tryed to order 1 of them. The man i spoke with at Magnum was a real gentleman,,,he stated the MAGNUM S9 was meant to be used with a 4 pill... that even with a 1 watt dead key going into the fatboy 1x2,,he said i'll kill the driver since the 2290 is only rated for 4-6 watts max, i would be putting way more into it & killing the life of it,,, NOW A FRIEND OF MINE SAID THE MAGNUM GUY WAS RIGHT IN THAT PERSPECTIVE,,,,, HOWEVER HE WAS GOING BY TOSHIBA SPECS & COMPARING IT TO A TX STAR AMP,,,NOT A DAVE MADE OR FAT BOY,,WHICH CAN TAKE WAY MORE THAN A TX STAR EVER COULD DREAM OF.... HONESTLY SPEAKING,,,, I HAVE BEEN USING MY FATBOX 1X2 FOR A FEW MONTHS WITH NO PROBLEM,, WITH A VOYAGE VR-9000 WITH NPC MOD,,,A RANGER SS158 FROM COPPER & A FEW OTHER RADIO'S THAT ALL SHOW A PEAK READING ON MY PALSTAR AM2000 METER OF 30-40 WATTS PEAK,,,WITH EACH RADIO HAVING A DEADKEY OF 1-2 WATTS & SWINGING CLOSE TO 40 WATTS PEAK & HAVE YET ENCOUNTERED ANY PROBLEMS...I USED THE FAT BOY THE OTHER DAY FOR HOURS,ALOT OF RAGCHEWING,,AND WHEN I TOUCHED THE AMP IT WAS STILL ROOM TEMPERATURE,,THAT FAN KEEPS THEM REAL COOL,,,UNLINE MY TX STARS THAT WOULD HEAT UP WITHIN 20MINS OF TALKING WITHOUT A FAN,THEY WOULD GET HOT TO THE TOUCH..... WITH THE 1X2 & THE ABOVE RADIO'S,I WOULD HAVE THE AMP KEY AROUND 100 WATTS AND SWING THE REST,TO AROUND 450-500 PEAK ON MY PALSTAR,,,AAIN NEVER HAD NO ISSUES,SWR IS FLAT,,,AMP NEVER GETS HOT......NOW I SPOKE TO THE COPPER TECH THE OTHER DAY & HE TOLD ME WITH THE WATTAGE TURNED DOWN TO AROUND 1 WATT OR SO,,,, I WILL BE FINE RUNNING THE FATBOY 1X2,,,,SINCE THE RF PEAK OUTPUT OF THE S9 - 40 WATT MODEL IS ONLY A FEW WATTS MORE THAN THE ABOVE RADIO'S I AM CURRENTLY USING ,AS LONG AS MY DEAD KEY IS LOW I'LL BE FINE....YET THE GENTLEMAN AT MAGNUM SAID IT WONT WORK,I'LL KILL THE FATBOY,,,,, MY FRIEND IS TELLING ME IT WILL WORK FINE, A FATBOY IS NOT A TX STAR & THE MAGNUM GUY IS GOING BY TX STAR SPECS,,,2 TOTALLY DIFFERENT AMPS ,,,COPPER BOARD ON FATBOY,,,ETC.........IM GETTING THE RADIO REGARDLESS BECAUSE I WANT IT,,,,, IM JUST CONFUSED HERE WHO IS RIGHT,,,WHO IS WRONG,,,MY FRIEND SAID WE WILL ADJUST THE MIC GAIN WHEN WE GET IT SO IT DOES NOT SWING PAST 40 WATTS & WE SHOULD BE FINE,,,,,, I COULDNT RUN THE MIC GAIN AT NOTHING OR CLOSE TO NOTHING OR MY AUDIO WOULD BE TO LOW,,,I DONT USE POWER MIC'S ANYMORE,,,ONLY ASTATIC 636 NOISE CANCELLING MICS, BE IT WITH MY RANGER 158,,,,VOYAGE VR9000 OR ANY OF MY OTHER TOYS ?? WHATS YOUR TAKE PAT ?? SOME1 IS OBVIOUSLY RIGHT & SOME1 IS WRONG..... OR ARE U STANDING BY YOUR INITIAL REPLY ??? THANX AGAIN BROTHER... |

the S9-40 watter is overkill for an amp with a driver is where i'm standing, mark! i'll BET you can turn the mic gain down on a correctly tuned S9 to 25% of mic gain, you'll probably see less then 15 watts swing rather then 40, and somebody who was getting an S-9 SIGNAL from you will STILL get an S-9 signal & quite PROBABLY notice NO DIFFERENCE in your audio-other then possibly some improved quality (depending on their proximity to you & the mode you are using).
swinging 40 into a single 2sc2879 will eventually kill it, if you don't have much background noise & the 'swing' is allowed to drop back to near zero between syllable/tone/audio input. 40 watts of carrier into one WILL kill it.
the S9 is an odd bird in that it was the 1st radio to allow 1 watt carrier & 40 watts PEP from the radio without heavy modding. on the other hand, many don't show much more then 12-15 watts 'swing' on an rms meter even while showing 40 on a PEP meter. showing 12-15 PEP on a grant xl is not all that difficult to accomplish, it still only shows 20 or in the low 20's PEP, and probably runs neck & neck with the S9 showing 40.
while i really don't care for magnum's as much as i used to, i do think they are the better export radio currently available, and may be in the market for an S9-175, just to toy around with....i said i'm done with magnums, but.....wouldn't mind seeing a 175 watt omega.... |

I LIKE & RESPECT YOUR TRUE UNBIASED OPINION PAT.... ACTUALLY THE 40 WATTS WOULDNT EVEN BE GOING INTO A SINGLE 2SC 2879...IT WOULD BE GOING IN TO A SINGLE 2290,,,WHICH WOULD THEN BE DRIVING THE 2SC2879'S...EVEN WORSE HUH !? FATBOY 1X2 = 1 2290 DRIVING 2 2879'S.........1 OF THE REASONS I WAS GOING TO GET THE S9 WAS I REMEMBER HOW IN PAST FORUM ARTICLES YOU THOUGHT VERY HIGHLY OF THEM.....ANY PARTICULAR REASON WHY YOU ARE NOT SUCH A BIG FAN OF THEM ANYMORE ? I HAVE A GOOD WEEK BEFORE THEY WILL GET MORE IN STOCK TO MAKE UP MY MIND..... I ALSO DO HAVE A MINT CONDITION LATE 80'S MODEL GRANT XL,,,, MAYBE I SHOULD JUST SAVE THE $ 300 & SOMEWHAT DOLLARS FOR SOMETHING ELSE...... I KNOW YOUR AN AMP AUTHORITY SO I LISTEN TO WHAT YA TELL ME ,,,AGAIN THE ONLY REASON I CONSIDERED THAT S-9 WAS TO BE ABLE TO USE IT WITH MY F.B. 1X2,,,, USUALLY I HAVE THE RANGER SS158 IN LINE WITH THE 1X2,,, THE SS158 SHOWS AROUND 30 P.E.P. ON THE PALSTAR,DEAD KEY SET AROUND 1 - 1.5 WATTS,,,PRODUCES DEAD KEY OF 100 WATTS ON FAT BOY AND SWINGS NEAR THE 500 P.E.P. ON THE PALSTAR,,NEVER HAD A PROBLEM,,,, BUT I KNOW THE MAGNUM WILL SWING MORE THAN THAT,,,,,I GUESS TO MUCH MORE,,,,,, I WILL ADMIT 1 THING,,,,IT IS A SWEET LOOKING RIG...... AS ALWAYS,,,THANX FOR THE REPLY'S PAT,DEFINITELY APPREICATED.........BE WELL & ENJOY YOUR LABOR DAY WEEKEND ! |

RE: 175 watt omega:
They are suppose to have an Omegaforce S45HP coming soon.
Suppose to be the first Magnum with the RFX 75 power module factory installed.
From what I've read, most people say the RFX 75 does about 125 watts pep. With the audio of the S45, it should be LOUD.

hmmmmm....125 watt omega? actually, 175 watts is a better choice, due to driver considerations for an 8 transistor amp. 125 is a tougher match for a smaller 12v amp, but wouldn't be bad for a converted HF (10m) amp....been a long while since i've had time to play with a soldering iron, but....
mark, i still think magnum is the better choice for an export radio. i just got turned off by the little picky problems that have arisen in there quality control over the past few years. i think the little problems are more assembly issues then design issues-for the most part. i still have trouble with MOST cb's using mosfets. the radio was NOT designed around a mosfet, rather it was modded to ACCEPT a mosfet. perfection in tuning needs to be attained, as well as perfection in powering, audio gain, rf amplification, etc, or else they produce some odd RF characteristics, particularly in SSB mode.
the 40 watt radios, icluding early dual final exports were designed for high drive amps, mostly 4x2879 tnt's, comet, telco, TS. there were some early solid state amps that were designed to take 'higher' inputs without smoke, yet still only produce 200-300 watts. when stryker came out with their 60+ watter, and mosfet radios followed with 60-100 watts, those radios really never matched any amp. yea, the dave/x/fatboy's could handle them, but you still were only playing 'A' ball. truthfully, the 175 watters are good enough to get you to 'triple A' nowadays, but then again, anything bigger then an 8 starts requiring mortgaging of the farm. 8 transistors (done right) is king anywhere but channel 6 or 11.
remember, after tons of testing & playing with my 1st S9, which did see almost 20 rms swing with 1 carrier, i stuck with-and still use-a grant XL, 20+ years old now, usually dialed in at 2 watts carrier or less, only showing around 12 rms swing, into a 1x4 driver box. the S9 was matched with a straight 4 driver. i just had better success with the grant & the 1x4 into bigger boxes then the magnum + 4. the magnum had some pretty good receive, but my ears said the XL was better.
any cb radio (they are ALL the same, no matter what ANYBODY says) that is broadbanded to cover 5 or more mhz (the S9 can go from 25.6-33 mhz nearly 7.5mhz bandwidth), vs the roughly 1/2 mhz design followed by the XL, is going to lose something. even the xl, after modding from 26.8-28 loses a bit. the exports try to make up some of it to get you all the extra freqs, but it isn't the same. |
