well i decided not to go the X force route of the sweet 1600 on 2 astrons.
Heres what i think ill do.
Run my HR 2600 into a TX star DX 667 run off of 2 astron 70 amp supplies. Yes im aware that the 667 has a driver so thats why i have a varable on my 2600 and yes i realise that the 2 70 amp astrons are a "bit much" but then again if i want to go bigger ill have the room in regards to the 140 amps availabe off of the 2 astrons. Ive decided not to go the X force route because it is biased class B and everyone and thier brother keeps on saying the X force will be a splatter beast on AM and SSB. Now i know i wont be able to run with the big boys on CH 6 but id care less about talking to the guys on 6 because i mostly run SSB to talk DX anyways.
Now i know some of you will probably make a few snide remarks to my desicion but heres what im thinking about doing.... So go ahead say what you want...... LOL |

One word, or item number:
KLV-1000
Why pay all the money for all those power supplies and all that money for that 667 when you can get a KLV-1000 or 1000P? 1400 watts PEP? Am I missing something... you mentioned power supplies... a 667 is not to bad for the mobile, but it's more cost effective to get the KLV-1000 if you only intend to run all the power as a Base.
Guess you might have a better reason for all that extra effort, and I'm sure you will tell me, but 2 Astron 70 amp power supplies and a Texas Star 667 are far from cheap, and a KLV-1000 is only $500... give or take a few bucks.
Just my 2 cents. |

Umm
I am glad you didnt go with the 2 xforce sweet16's
Cause if you did you would have a hard time finding a sweet16 made by xforce cause they dont make them.
Texas star makes the sweet16. |

If you were to have available a $120,000 Hewlit Packard spectrum analyzer to make the comparison you may think different, but good luck in any way you go. |

Taz i didnt say "X force sweet 16". It was a typo. Were I said "X force route of the sweet 1600 on 2 astrons" it should have been a or instead of a of. I think you are purposly nitpicking my post and i dont like that! :-(
Tech 671 what are you referring to making comparison? |

The item you are choosing is not as "clean" as the one you decided against. |

I ran a 667 and it was a great amp, ran hot but nice amp. When I ran it with a clipped radio it was a splattering SOB. Even after I had the radio cleaned up it would still bleed. Alot of how bad an amp splatters is the signal you put in. If one were to run an X-Force base amp and not try to squeeze every last ounce out of it and run a clean signal radio into it you would be in great shape. If your neighbor has a 7 dollar third world country made junk telephone anything will get into it. Should sound great there Hoosier, go for it. I like Texas Star amps but they are not the cleanest but so what give it a shot. If ya don't like it sell it and try again. |

Then please enlighten to us what amps that are avaiable are clean and look all nice and pretty on a $120K spectrum analyser. What does say a KLV 1000P look like on one?
So why is my choice bad and the other choice good? Id sure like to know why i make all these mistakes in my descisions! LOL |

671, Copper's has one of these machines? I sure would like to see some reports on some stuff like noted in this thread. I think that would be very helpful to many perspective buyers out there.
I am interested in the KLV base amp and would love to see some understandable results from that line.

Im interested in the KLV 1000P myself but the problem is nobody in my area runs one! Plus my tech has told me a few things that kinda scare me away from the amp as well like if a guy buys one and has trouble wit it (like the amp not working to begin with right from the box!) well hes basically out in the cold and has no option to return the thing plus ill be shipping is astrononmical the amp im told weighs well over 60 lbs!

Hoosier,
My reference was specifically to the 667, 500, 1200, and 1600 vs a comparable unit from XF that I have had tested by an enigineer through the spec analyzer.
I have no idea how "clean" the KLV base amps are as I have not tested them. I would suspect if driven modestly with a "clean" transmitter they would be fine. |

$120,000, for a spec-an, man he got burned 10 fold over. my motorola 2600 communcations analyzer came with a high performance spec-an with markers built into the unit and the whole unit was no where near this. granted the resolution of my specan is 20khz compared to most stand alone specans resolution of 1khz(meaning; it can't break down the sideband info of modulated carriers as well) but it is acurrate and will show harmonics and out of band imd's very well(not to mention it will perform 15+ other tests that a stand alone specan will not).
but you don't even need a specan to see if an amp is suitable for ssb or am. you can manually trip the relay and measure the voltage at the base of the rf trans. if .6 -.75v they will definately be fine and are class ab. if it is between .5 and .6v then a scope needs to be used to verify linearity. if below .5v(usually below .55v) then they are class c and should not be used for am or ssb if 'cleanliness' is a concern. these readings work regardless of the manufactures claim of b,c, or whatever class. if the voltage is in the questionable range(.5v - .6v)a scope on the output of the amp while a single tone(steady whistle into mike) is modulating a.m. will also let you know. if the radio is set at 100% modulation but yet the amp is cutting off the negative peaks, then it is not acceptable for am or ssb. if 2 tone ssb is put into the amp that is cutting off the neg peaks in am then you will see what is known as crossover distortion. so in am or ssb there will be increased trash. may sound awesome on the air(what i guess really matters to most) but the signal is not clean in the 'rf spectrum'. if a.m. looks good on the scope, then it will most likely be perfect for ssb also.
i'm not putting down any amps here. just helping to describe some easy ways to determine if an amp is truly an am/ssb amp. class c amps 'technically' should only be used for fm work. but class c amps are cheaper and easier to make, and this is why there are so many in the 10mtr/11mtr world. 'nontechnically' you can use anything you want if it sounds good. i'm a purist, so my concerns go beyond sound alone, but that is me. |

Tech 671.
OK so what you bascially are trying to tell me and clarify me if im out of sync, that the TX star 500 667 1200 and sweet 16 as tested on a sepct anyalyser are cleaner/dirtier than the XF brand? I know the X Force bases all use what they say is class B and ive read/ heard both good and bad about the X Force class biasing. I just want to be really sure of what im getting into before i ddecide what i really want here! |

Running two power supplies like that can be done, but its tricky and if it isn't "right", bad things happen to expensive stuff. I think your best choice is the KLV 1000p, or the 1000. I don't like the x-force amps, and the only x-force base amp I heard sounded terrible. I also see alot of people trying to sell them soon after purchasing them. If you are contemplating spending all that money for those power supplies and the tx-star, you could just save a little more and get a Henry, ACOM, Ameritron, or whatever. But for strictly 10-12 meters base use, the KLV box is the way to go. |

Hearing one item that didn't sound good does in no means make them all bad. That's a pretty broad brush to paint any product. |
