Others can argue the tech. advantages pro or con. Some feel they need 2 KW. I don't.. For a DXer antennas & skill are more important than a few more watts. I like the way it works with my K3.

This discussion just reiterates the general point that you can't make a pure
price comparison between a differentiated product and one that is not. The maker of the undifferentiated product will maximize his profits when he prices it at the marginal cost of production. But the maker of a product with special desirable features will maximize his profits by pricing it above the marginal cost of production by an amount that depends on the perceived extra value, setting the price as high as possible while still leaving the buyer with some "consumer surplus."

If I could afford one, I would get it. I am building a kit that will
provide 300w but NOT with all the extra features that come with the KPA500. I will have to run a 28vdc PS for the 300w linear so not portable like the KPA500. I bought a used Mirage A-1015G for 6m (125w driven by K3/10). Fortunately, I have acquired a Harris TV amplifier to produce up to 1100w on 6m (the K3/10 will drive it to 800w). With luck I will have 800w running for the July CQ VHF Contest with newly erected 6-element yagi. 73, Ed - KL7UW, WD2XSH/45 ====================================== BP40IQ 500 KHz - 10-GHz www.kl7uw.com EME: 50-1.1kw?, 144-1.4kw, 432-100w, 1296-60w, 3400-?

For me it was 1958, age 11. My first station was a Viking Adventurer and
HQ-110 (had it for 12 years). Never touched anything more sophisticated until I upgraded (in 1970) to an HW-100 (used it for 12 years, too). In the early 1990s, I got into restoring and operating "vintage gear." I had several stations on the air, sharing an antenna system. Viking Valiant/NC-303; Viking Ranger/HQ-170; Viking Adventurer/HQ-110; Eico 720/730/722 with Drake 2B/2BQ; Collins S-Line with 30L-1; Globe King 500/75A-4. So, I finally had a chance to try all the radios over which I had salivated as a teenager. Today, the only remaining jewels are Globe King 500/75A-4. With regard to amplifiers, unlike transceivers, you're only dealing with one of two "directions" - output. Issues like efficiency are important but probably more important are issues of clean output and reliability. This is especially true for contest use where the amplifier can be pounded for 48 hours, straight, at maximum power out and greater than 50 percent duty cycle. I am currently using an Alpha 87A and Ten-Tec Centurion in an SO2R set up. Both work well, and work reliably. If I replace either with a KPA-500, it will probably be the Centurion. Here, the KPA-500 has the instant switching/instant tuning advantage. But, it runs half the power. It also covers 6 meter - a band I have never tried, and for which I have no antenna(s). I have no doubt about reliability or service responsiveness when it comes to Elecraft. So, it will come down to how much is instant bandswitch/instant tuning worth to me. And, will I miss the extra few dB in signal strength. I have not even considered replacing the Centurion with alternative solid-state amps from Ameritron, Tokyo Hy-Power, or the one from Italy.

Droolin Over Gear (was Re: KPA500 vs others)

Wow, I feel like a young pup. Again. Huh. Always seems to be that way. Got licensed in 1987, at the age of 14. Started out with a set of Drake twins, but the filters on the receiver weren't aligned quite right, so USB had to be done on the 4.8 KHz wide setting. I set my sights relatively low as these things go and *really* wanted the Kenwood TS-440SAT, although I wouldn't have turned my nose up at an Icom IC-761. Had lots of fun though, and fell in love with cw in spite of my best efforts to hate it. Didn't get my hands on an iambic paddle until I'd been using a straight key for a fairly long time, about four or five years; also got a bug and learned to use it tolerably well, but never could, and still haven't, got the hang of squeeze keying. I'm definitely a single lever kind of guy and have used iambic paddles that way. Now I really want one of these Vizkey bugs by K4VIZ. And am very anxious to get my hands on the KX3, much as I love my K2/100. Which I shall keep forever and always no matter what, because of where it came from and how i came by it. I mean, besides its being a super fantastic little radio. I really should get it updated to latest spec and add the 160 meter module and noise blanker some day. Yeah, KDSP2 is tempting as well, but think I'll hold out for the KX3 for that.
Now if only I weren't all thumbs.

Hello Mike and others,
As mentioned in my previous emails in this reflector, I am awaiting KAT500 so that I will know the total cost of KPA500+KAT500. LDG tuner may not meet my requirements in 6 metre I have no worry about Elecraft's competence to give us good performers but the following issues hinder my decision in favour of KPA500: 1. Hams usually have more than 1 radio. I have the big Icoms and K3. Therefore, I need a linear amplifier with at least two inputs for two radios; 2. Again, we often have more than 1 antenna but KPA500 has only one RF output for 1 antenna. I believe the KAT500 will accommodate more antenna with memories per antenna per band. Therefore, I need to wait for more information about KAT500. In city area of Hong Kong, property prices are not much less than that in downtown Manhattan, NYC. We do not have the luxury in space for every radio having its own dedicated linear amplifier.

And, the VK amateur using the same "tool" would never bother to turn on his
rig, because he is limited to 400W. That said, you can often make contacts when some software predictor said it couldn't happen.

Sorry Jack, in my opinion your comment is quite irrelevant to the point that
Brian made. It is pretty obvious that if you cannot hear the VK, then no amount of power is going to make you successful, be it 10 watts or 1500 watts. You are correct in that with great band conditions, you will be able to work the DX with 10 watts BUT you will have to wait until all of the folks who are running 1500 watts have finished, then you will have to wait until the folks running 500 watts have finished. The following of the KPA500 is very similar to what used to happen on the Ten Tec reflector, no matter what Ten Tec did, the 'Ten Tec cult' worshipers would just gush over it; now it is Elecraft's time! It is pretty simple to understand that a 500 watt signal is not going to be heard over a 1500 watt signal, given identical circumstances. 73, Tom - W4BQF -----Original Message----- From: [hidden email] [mailto:[hidden email]] On Behalf Of Jack Chomley Sent: Wednesday, June 22, 2011 7:44 AM To: Brian Alsop Cc: [hidden email] Subject: Re: [Elecraft] KPA-500 vs others On Wed, Jun 22, 2011 at 9:27 PM, Brian Alsop <[hidden email]> wrote: SNIP>> > For me, it is pretty convincing (I'm a primarily a DXer) that 1500 watts > suits my operating needs, 500 watts does not.

But circumstances are rarely "identical".
In any case, if you don't want a KPA500 don't buy one. If you do, then do. What about that is worth all of argument about it? I had to cancel my order for one because I needed the funds for another purpose. Once I sell some other unused stuff I plan to reorder. Not that Im ready to get rid of my 1500 watt amp, but for most circumstances, the bit of additional power plus ease of integrated operation and low hassle factor makes Elecraft's amp a worthwhile addition.

I just fired up my Ham Cap and DX Atlas Applications that measure s/n ratio on a AZ map. Choosing VK4 as the other end of a 14MHz circuit, the predicted results at VK4 with a three element Yagi-Uda are as follows: 100w - s/nr 40 dB 500w - s/nr 47 dB 1500w - s/nr 51 dB In all three cases the s/nr is adequate for two way communication. The circuit between N5GE and VK4 on the one way path from N5GE could be as high as 51 dB at VK4 if I'm using my 1500w TX, but on my end if VK4 is using 100w, then my 1500w doesn't help make the s/nr at my RX even one dB better. Good antennas and RX are 30% of the equation and skill is the other 70%. 73, Tom Amateur Radio Operator N5GE ARRL Lifetime Member QCWA Lifetime Member On Wed, 22 Jun 2011 11:27:42 +0000, Brian Alsop <[hidden email]> wrote: [snip] >BTW in the 500 vs 1500 watt debate, there is a tool which can pretty >much settle the issue.

The 10 watt guy might work him well before the 1500w guys. Propagation
might be favoring the 10 watt guy, he might have better antennas, he know where in a pileup to call or when to call in a simplex pileup etc. I worked the VU4 and S21 dxpeditions with an Acom 1000 running about 600 watts in my house shack. I never felt the need to run out to the radio shack and crank up the Alpha 99. My desire for the KPA500 is a lighter DX/Contest-pedition worthy amp and a nice matching amp that takes up far less room than the Acom in my home shack and I wanted to have 6m. There is nothing on the market that comes close. I had a very bad experience with THP and will never buy anything from them. Power is no guarantee to working anyone.

But not as disappointing as finding that you can't communicate at all with
your QRP rig because there is a contest on with several layers of stations on every frequency. I like to take my portable QRP rigs seriously as safety equipment, and the need for that function doesn't go away where there is a contest on. 30 m may not work. 73, Erik K7TV Ron, AC7AC wrote: It's disappointing when I call someone on one of the QRP frequencies and find out he's running a kilowatt.

In that regard, a lot of folks seem to forget about a little item in Part 97
of the FCC rules: Sec. 97.313(a) An amateur station must use the minimum transmitter power necessary to carry out the desired communications. But then again, when I was a kid I remember my dad scratching his head in amusement over a couple of local fellow hams running their Collins kilowatts on AM... to talk across our small town. Guess things haven't changed much.... 73, Al On Wed June 22 2011 10:37:19 am Ron D'Eau Claire wrote: > That's one of the nicest things about 30 meters: 200 watts maximum, no > matter what.

It would even be nicer if US hams actually OBSERVED this rule!
I have even heard a guy telling his QSO partner that he was running a kW!

While I certainly enjoy QRP, it should be be remembered that one of the greatest problems facing ham radio is the increasingly high noise level from all sorts of switching power supplies, plasma TVs, motor controllers, solar power systems, and power line arcing. I live out in the country, with my nearest neighbors nearly a block away. Although my noise level is sometimes as low as S1 (on my calibrated K3), it can increase by 20dB or more when someone fires up one of those noise sources. On 6M for example, one neighbor (at about 120 degrees), has a solar installation that brings that noise level up to about S5 during the day; another, at about 60 degrees, has a switching power supply with a 75 kHz wide, S5 hump of noise that drifts up and down between about 50.05 MHz and 50.2 MHz. When either of those sources is active, it means that the station on the other end needs 24 dB more power to work me than if the noise were not present. 24dB is roughly 250 X the power. At least half of my 6M QSOs this summer would not have been possible if those noise sources had been present -- I would never have heard the other station. Most hams have far higher noise levels than I do. The greatest justification for running more power and putting up bigger and better antennas is RF NOISE experienced by the ham on the other end. 73, Jim K9YC ______________________________________________________________ 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 |

Keep in mind that might not have been a serious statement. I know there has been at least one occasion where my QSO partner on 30M said something of that nature in jest. Let's hope the one you heard was also in jest.

Yes, it would be different if everyone honored FCC rule 97.313(a).
We should all then be giving 449 reports on contest day rather then 5NN. In fact, we could make it simpler by saying that 449 was merely a long string of dots followed by a dash and then a dot. 73, phil, K7PEH On Jun 22, 2011, at 9:27 AM, Al Gulseth wrote: > In that regard, a lot of folks seem to forget about a little item in Part 97 > of the FCC rules: > > Sec. 97.313(a) An amateur station must use the minimum transmitter power > necessary to carry out the desired communications. > > But then again, when I was a kid I remember my dad scratching his head in > amusement over a couple of local fellow hams running their Collins kilowatts > on AM... to talk across our small town.
