ok guys, another dumb qeustion from me  . I have a Bear cub 200 an the guy i got it from said his radio was dk 1 watt an swang to 30 an it ran the box just fine. now with my RF gain all the way down on my turbo i am doin 5 watts with NO swing. On low it shows a forward swing an on high it shows a backward swing, an it sure aint even close to no 200 watts....lol. Am I drving it too hard with 5 watts? My radio with the RF all da way up is only 10 watts an it really backswings. I only tried it once...lol. I have tuned it an loaded it on both high an low with the same results. Plus one more dumb question for ya. There is a switch that says gain an unity.with the switch on gain a light is lit up an with it on unity the light goes off. Does anyone know what that switch is for? Once again any an all info will greatly be appreciated

From what I have learned here is that any thing over 2 watts DK is to much for an amp that small.A 30 watt swing is a little on the high side too. I would get the radio adjusted to a 2 watt DK and swing no more than 15 watts or so, maybe even 20 watts if the amp is tough enough. The RF gain on your radio does not control the transmitter. It only controls the reciever allowing whatever amount of recieve you want to hear. Don't know what the unity switch is for.
Allen man, no such thing as a dumb question, only dumb answers, you dig? 73 to ya Kenny

Allen,
I've learned over the years a Amp rated at or advertised wattage usually will only do 2/3 rds
as advertised say 200 watt amp 175 watts safetly without friing it, see the places that sell them want you to drive it to the max so they can fix it for you!!! |

Problems all over the place for this guy...his RF gain controls his power...he's using a Saturn Turbo and trying to run and AMP?
Wow. |

I WISH Pat00! This dang turbo of mine with the RF power all the way down is only doin 5 watts an all the way up is only 10.By the way hotwire I meant RF power not gain, my fault...lol. With the flip swithced on the back of my Turbo I do just as much as the Bearcub 200, go figure. Cause the Turdblow is only doin 90 with the switch flipped  . One of these days I am gonna take the Turbo in an figure out why it's doin what it's doin. I want the lowest DK with whatever swing I can get, with the switch flipped of course . Thanks fer all the info though. It is greatly appreciated .

wait a second, allen. i think what you have is the amp section of the turbo switched into or out of line-that is what the switch is for. as for watt readings-what meter are you using, & is it rms/avg ONLY, or rms/avg & peak/pep??? if you're using rms or avg scale to read peak watts, a pretty well tuned turbo could quite possibly be showing 'only' 90 watts-on true peak, that would BE CLOSER to 150 or more. exactly where it should be. (same for the bearcub amp...). as for 5-10 watts, is that with the switch in 1 position, & when you 'flip it', it shows 30-50 (these are dead key readings) & it swings to 90 then? if that's the way it's working-then YOU'RE GOOD-probably. the 'low power' switch(built in amp out of line) is for use when talking locally or when tvi is a problem. when on 'hi power', that's the normal setting & for long distance/dx. that radio was made to be used at the 150 watt level. the only amp you should use with it would be a HIGH DRIVE tube amp-such as the klv1000p, none of the smaller klv's will handle the full power, or an 8 transistor AC powered custom amp. that little bear cub is useless for the turbo. |

Thanks Pat00 fer that info. With the switch flipped an the RF power all the way down it shows 50 watts with NO swing an with the RF power all the way up it shows 90 watts with NO swing. Now when I tell you what meter I am using I know your gonna laugh. It's a radio shack swr/power tester. 20w-2000w scale an has avg/pep mode. An thats what the wattage shows on pep. If I had the money it would be takin in an put on a real set of meters an tuned the right way. I was told by the guy i got it from with the switch flipped it was doin 180 an i know the place he had the work done to it an they are a very reputable place. We had it on a set of dosey meters an it showed the same as my radio shack meter, so as always i am confusterated One day It will be done right or sold to buy another radio, hopefully another base as i hate using power supplies casue i cant afford a big enough one to run a decent mobile for a base. Once again Pat00, I appreciate all the info Hope to catch ya on the radio one of the days

90 watts dead key from 2-2290's?OUCH! where's that SMOKE comin' from???
the BIG custom amp makers only recommend 60 watts or less carrier from their 2-2290 amps....

See Pat I have no idea what is in the radio. Whatever is in the radio is what was in it an what its doin is what is was doin when i got it...kinda confusin huh? . I didnt think it had 2290's in it because it is a older radio but like I said before I kinda dumb when it comes to this stuff so please bear with me....lol. Like I said before, one of these days it will go into the shop. Hopefully it doesnt go bang or smoke before then...lol

On ssb there sould be no d/key it should be zero untill you talk,if you're getting a 25 watt dead key then the carrier balance is out of adjustment Patzerozero should have caught that c'mon PAT wake up,lol.Bigbob |

open the cover to the radio, near the coax connector on rear of radio you should see 2 round white 'thingies' a bit smaller then a nickle & as thick as 2 of 'em. they should say 2sc2290 on them.(the NEW dx versions & 6300/6900's are using sd1446's...)if you follow wire off switch added on rear, it too should go somewhere near where that section meets up with the 'basic' section of the radio.
that would tell you that you have a radio with the correct transistors modded to switch the amp out of line. do NOT use the bearcub-which is useless for a properly working turbo, or any other amp with it til it's setup correctly.
the radio, as from the factory, should vary a dead key on AM from about 5 watts to maybe 50-under 40 is where it SHOULD be set to. with key set around 35, it should swing around 150 watts give or take. dead key lowered to 5 & it should still swing anywhere from 60 to 120. that is what it SHOULD do factory-no peak & tweak-& give NO problems. with the 'amp-removed-mod', what it keys depends on where tech set it, but 1-10 watts would be nice, with swing 25-30.
SSB swing should be a bit LESS then AM swing. |

Thanks Pat fer that info..I will look when I get a chance an see if thats the case. If those 2290's are bad could that be the reason why i'm only gettin that much out of it or could the regular finals be the problem? Like I said, any an all info is greatly appreciated
