Re: [Elecraft] [K3] Will I Lose the 120 Watt Max If I update The Software?
What if he's running about 5kw out? This would make sense. 10% increase in input gives you a 10% increase in output power. This is of course ignoring the dirty signal you are producing.

Re: [Elecraft] [K3] Will I Lose the 120 Watt Max If I update The Software?
But that's still only a fraction of 1 dB gain in signal - not detectable on most S-meters. RF power is one place where more yields diminishing results. The increased signal at a receiver when going from 10W to 100 watts output is exactly the same as the difference between 100 and 1000 watts, but that extra 900 watts costs a lot more to produce than the 90 watts.

Re: [Elecraft] [K3] Will I Lose the 120 Watt Max If I update The Software?
110W is the maximum with the latest firmware. Running any higher than that is not recommended it probably should invalidate your warranty ;) ~Iain / N6ML On Sun, Sep 20, 2009 at 7:22 PM, -.-. --.-N3TU -.-. --.- connectme...@hotmail.com wrote: My software is about six months old and I heard rumor that the K3's power may be backed down to 100 watts.

You have a real problem with your amp if going from 100 watts to 110 watts drive gives you a difference of 500 watts output from the amplifier.

Re: [Elecraft] [K3] Will I Lose the 120 Watt Max If I update The Software?
A 10W difference makes 500W more? that's a relation of 50 to 1.MMM sounds wierd,I have never seen an amp that makes that relation,there is definitively something wrong in there.

Re: [Elecraft] [K3] Will I Lose the 120 Watt Max If I update The Software?
I'm not causing distortion and stations say it sounds clean on the air. I think I am going to get the amp looked over.

Re: [Elecraft] [K3] Will I Lose the 120 Watt Max If I update The Software?
Just how much power are you running? If going from 100 to 110 makes a 500 watt difference in the output, then you must be putting out 5000 watts with 100 in, assuming the amplifier is linear. Somehow I suspect this isn't the situation... Seriously, in general amplifiers need about 50 watts input to get full legal output. That's about a 15dB max gain as set by the FCC rules if I remember correctly. If you need to put much more than that in, then you either have a lot of loss in the input coupling network (this is intentional on some designs), or the efficiency of the finals is really bad (old tubes?). Your strategy of getting it checked out is a good one. On Sep 20, 2009, at 8:14 PM, -.-. --.-N3TU -.-. --.- wrote: I'm not causing distortion and stations say it sounds clean on the air.

Re: [Elecraft] [K3] Will I Lose the 120 Watt Max If I update The Software?
Yes, I'm going to get it checked out. Full legal limit is at 110 watts. I have original tubes in the amp. I guess I need two new 3-500z's. I already have new caps in the power supply.
