Wondering if anyone has a suggestion of a solid state amp or "pushing" the K3 PA to obtain 150 watts out on 160m?
A kit or HB would be fine... 73, Julius n2wn

Julius,
Do you want to amplify 10 watts to 150 watts, or 100 watts to 150 watts? The former is nearly 12dB- about 2 S-units - while the latter is less than 2dB - about 1/3 of an S-unit, a difference which would be very difficult to discern on the air. -- 73 -- Brian -- K1LI On Fri, Dec 11, 2009 at 10:44 AM, Julius Fazekas n2wn <[hidden email]>wrote: > > Wondering if anyone has a suggestion of a solid state amp or "pushing" the > K3 > PA to obtain 150 watts out on 160m? > > A kit or HB would be fine... > > 73, > Julius > n2wn > > ----- > Julius Fazekas > N2WN > > Tennessee Contest Group > http://www.k4ro.net/tcg/index.html > > Tennessee QSO Party > http://www.tnqp.org/ > > Elecraft K2/100 #4455 > Elecraft K3/100 #366 > Elecraft K3 #1875 > -- > View this message in context: > http://n2.nabble.com/150-watt-boots-for-160m-tp4151943p4151943.html > Sent from the [K3] mailing list archive at Nabble.com. > ______________________________________________________________ > Elecraft mailing list > Home: http://mailman.qth.net/mailman/listinfo/elecraft > Help: http://mailman.qth.net/mmfaq.htm > Post: mailto:[hidden email] > > This list hosted by: http://www.qsl.net > Please help support this email list: http://www.qsl.net/donate.html > Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

Hi Brian
100 to 150... Sometimes that's all you need to go from "n2?" to "n2wn" ;o) It may not be realistic, but might be fun to play with if not too expensive. All the 160 contests allow LP to 150 watts... 73, Julius

Why can't you just hook up 120 volts AC as your power source instead of that puny little 12 volts DC thing. Not only would you get 10 times the voltage which according to Ohm's Law gives you 100 times the power (thus, legal limit plus) but you also are using 60 Hz AC. Thus, you already have a kick start on that RF frequency. Why start out at DC when you can do so much better with AC. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

In all seriousness.... I don't think I would "juice" the K3 to get 150 watts out. Some did that with the K2 but I am a little reluctant to do that with a $2K+ rig. Of course your mileage may vary....but find a cheap amp. Like an AL80A. You can get them for around 700 dollars on Ebay. I did that .... ran the amp at 150 watts in the NAQP contests.... But, then they changed the rule to 100 watts. Or find an old HW101...jack the voltage up on the plates and screens....drive it hard and you might make the 6146s produce 150 watts for a contest. There is a gentleman somewhere on the net that has done that. Of course...your definition of cheap may be different that mine. Lee K0WA In our day and age it seems that Common Sense is in short supply. If you don't have any Common Sense - get some Common Sense and use it. If you can't find any Common Sense, ask for help from somebody who has some Common Sense. Is Common Sense divine? Common Sense is the image of the Creator expressing revealed truth in my mind. - J.

I am reminded of the recent sale item from Elecraft. The 2010 ARRL Handbook is to have a 250 Watt HF amp design in it. One ought to be able to drop the K3 output appropriately to drive it to 150 Watts. 73, Dick - KA5KKT ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

A good article on the value of a DB is an old timer in QST I think it was,
Station design for DX I guarantee you that if you improve your station by 1Db or more you will tell the difference, have done it and it works. A whole new layer of DX opens up for every DB you can find. I see comments all the time that lossy feedlines or matching or this and that only costs a couple DB and you cant hear that. Amen I dont hear you in the pile ups. There is an audiophile site somewhere on the web that lets you adjust volume in DB steps, you may be quite surprised at what your ear can detect in DB changes. If a Db or two makes no difference than buying a K3 that has better specs by a DB or so should also make no difference. I encourage others to not worry about loss of a few DB, makes for more DX for those who do.

In reply to this post by Guy, K2AV
This may be true and probably is...but as one other fellow said....1 DB is the difference between hear or not. Now...in contesting...that is points....or even a multipler which could be many more points per contest. So, I appreciate the comment here...is is the competitive edge that is driving this thread.

On 160, you could try a class-E amplifier; you're probably not going to use anything but CW.

I'd prefer to see the long delayed Elecraft 500 to 1000 watt amplifiers
that have been delayed, apparently because of the intense development of the K3 which hopefully is nearing an end. An amplifier with QSK, an internal tuner comparable to the K3 tuner, and integrated with the K3 with Elecraft's quality and attention to detail would cause money to leap straight from my bank account's to Elecraft's bank account. 73, Dunc, W5DC ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

In reply to this post by Vic K2VCO
I agree with Vic. You'll never notice the difference when a signal is -73 dBm or -72 dBm, ~55 dB above the noise floor, but at or below the noise floor, you'll definitely notice it. Case in point from the real world today was JT1CO on 160 this morning. There were many more folks listening than actually hearing. I bet many of those who could not hear would have given anything for another dB or two of S/N (either from better receive antennas or transmit power at the other end). 73, Bill |

Let me get this right. You are looking for reassurance that money you
haven't spent will be well spent upping 100 to 150 watts. Perhaps there is some part of you that doesn't believe it, or you would have done it already? Maybe you should listen to the skeptic there. Well, if you do go spend it, your banker thanks you, your suppliers thank you, but your operating savvy will dictate your success far more than the extra watts. I can make a much better case for "the economy needs it" than the far end. The Bell research DID involve accumulated noise and distortion on multiple circuits switched in series to make longer circuits, and how much then-manual maintenance could be needed based on customer's perceptions of circuits. Multi-megabucks of expense per year riding on it when gas was a nickel a gallon. So before you folks go dismissing it.... The trick at a given ham station is the accumulation of a little here and a little there, and yet. Eliminating loss at a half dozen places, and size of feedline, gain of antenna, etc can ad up to dB's noone argues about. 73, Guy.

Those who believe in authority and that God punishes tinkerers, PLEASE SKIP this message.
2SC2782 is rated at 80W min each at 175 MHz so getting 150W from two on 1.8 MHz should be peanuts; the main reason why they are restricted to 110W in K3 is linearity (across bands) + component ratings. At higher power, the efficiency can be higher and thus K3 may actually run cooler! So how to get 150W out of K3? 1. ALC would not let it. It needs to be fooled, e.g., by changing a divider in the SWR unit to indicate 100W when it is 150W. 2. At 150W the output impedance would not be 50 Ohm; it would be 35-40 Ohm with extra impedance added by LPF, which are designed for 50 Ohm. You need a manual tuner that you will tune for max power, not min SWR. If higher SWR causes power fold up, the SWR circuit needs to fooled again. 3. The radio would take more amps, say 30A, and the fuse may go out. If so, change the fuse or reduce the power so that the fuse is not tripping. Is it worth it, I am not sure. In contests, the extra power may make a real difference. Would Wayne and Eric approve? Never officially! Would K3 be ruined? I doubt it. Would I do it if I wanted to win a 160m contest in LP category and had no other alternatives? Perhaps on CW but never on SSB due to high IMD. Corresponding story Many years ago a power supply for IC-735 broke and the spare one was for 5A max. Tuned for min SWR the power was 5 W. Tuning for max power out generated 25W. Later, I tried the same trick with IC-7000. It was 5 W no matter what the tuning because of strong power folding under high SWR. Not sure what K3 would do. But there is a possibility that one can get 10-20W more just by tuning for max power out. Ignacy

Guy, Two db does indeed make a difference no matter what you or the Bell Labs results say, and that's why the search for an extra db or two continues for anyone interesting in contesting or DXing in noisy conditions. A couple of years ago I generated some audio files to demonstrate exactly that. I recorded some scratchy band noise from 80m and mixed it with computer-generated CW of varying levels. Down at the noise level, even one db was perceptible and two db made a functional improvement. In a CW contest or in a pileup that could make a significant difference, although I'll admit that two db may not make enough difference for SSB (I also never tried it). I promised Pete I would clean up the audio files and send them to him for inclusion in the Contest Wikipedia ... I'm very delinquent on that but will try to do so within the next two or three weeks. Whether ANY increase in signal strength is worth the money required to achieve it is purely a function of the station owner and his objectives. For some folks, spending an extra $1K to $6K to get 12 db from an amplifier is not worth it. Others have obviously spent ten times that amount on towers and antennas to pick up just a few db. 73, Dave AB7E Guy Olinger K2AV wrote: > Let me get this right.
