Re: [Elecraft] News from Visalia! (:-))
Hi, No tuner is fine me. Tuners belong at the far end of the coax, not in the shack. But is it really true that the power supply is linear? Sounds like a terrible waste of energy to me. Switchers *can* be made quiet these days. Switchers are also much more adaptible to various primary voltages. On the topic of 120/220V, of course I have nothing against 220V which is a must in Europe, as long as it will run on 120V. I do not currently have 220V in the shack but could relatively easliy install it as the breaker panel is just next door.

Re: [Elecraft] News from Visalia! (:-))
It's nice that you bring up the SPE 1K, since it demonstrates very nicely the loss you can suffer with a built-in tuner. The ARRL review (http://www.arrl.org/files/file/protected/Group/Members/ProductReview/pdf/pr0909.pdf) said that there was 100-200W loss in the internal tuner, and presumably this is into a matched load in the laboratory. With a mismatched load the losses are generally going to be even higher. With solid-state power costing upwards of $3-$4/watt these days ($3.20 in this case), why anyone wants to leave $500-600 worth in the box is beyond me. But then I could never get my arms around the whole mismatched antenna/ladderline/balun/tuner thing in the first place.

There is a button on front that says "ATU", but Bob was not giving anything away. The linear supply makes it much more multi-TX site friendly.

Re: [Elecraft] News from Visalia! (:-))
"... but If there isn't an ATU on board as I recall there was with the earlier prototypes of the bigger Elecraft amps, I wish that there were one with the KPA 500 and I'm disappointed..." The SPE internal tuner (and even the THP external tuner) can only handle about a 3:1 SWR. A wide-range autotuner needs a much greater range in component values, as well as higher voltage-rated and higher current-rated components than does a limited range tuner. Look inside a LDG-1000 or MFJ-998 and you'll see what I mean. Adding a wide-range tuner capability inside the KPA500 would add considerably to the size, cost and complexity of the KPA500. When it comes to an amplifier, I prefer an external wide-range tuner. Just my opinion.

Hi, Yes please, a remotable, weatherproofed 500W tuner with balanced capability would create an instant order here. Until then, I will continue to rely on my modified MFJ tuner (remote the "tune" function with a wire and weatherproofed in a plastic feed container). It's starting to show signs of corrosion and decay after 4 CNY winters but it's still working fine. I have a spare on hand to install when it gives out. It's cheap enough to be a throwaway item.

Rumor level now- The modular jack on the back is currently undefined, but is NOT just an extension of the K3 ACC connection. An ATU connnected there was mentioned. And, as I said, there's a button with an ATU label. The most knowledgeable person is no longer here, but the active devices are apparently a pair of 750W devices running at 60VDC.

Re: [Elecraft] News from Visalia!
I agree, yes please, a remote-able, weatherproofed 500W tuner (capable of 160-6m) would create an instant order here too. I have relied on SGC tuners for many years, mobile, marine mobile and now at my small suburban plot where I have a custom DX engineering 50+ foot vertical with 40 radials. The beauty of SGC tuners is they only require a 12v source. In every situation these tuners have performed flawlessly in harsh environments for years. I was planning on getting a 500W Tokyo Hi Power amp at Dayton this year, but seeing the Elecraft amp, I will wait. The problem is that no one makes a 160-6M remote weather proof tuner capable of 500-600 watts which only needs 12v. SGC's 500 watt tuner doesn't do 160M according to their specs.

Re: [Elecraft] News from Visalia! (:-))
I agree: I can get an ACOM 1010 (admittedly, with a tube) around (below) that that price with the handy TRI tuning and 800w to do the same thing, with paperclip reliability to boot. Also, an ALS600 with the Linear Power supply, AD5X Full Break In mod and an external bandswitching accessory plus an MFJ998 would come in considerably under the $2,000 price. I should know.

Let me suggest; however, that there is an "iron triangle" that most people consider as trade-offs for purchases, either consciously or subconsciously : 1) Performance, 2) Style, and 3) Cost. In general we all seek to maximize performance in whatever we wish to acquire or purchase, whether it be power level, duty cycle, weight, distortion, and HF and 6-meter band coverage. I will argue that Style is also an issue for everyone on some level - do we really need to have any of our cabinets painted? What about knobs? Must they be black? Knurled? Plastic? Metal? Ultimately, Performance and Style are phase-locked to COST. The more you demand of Performance and Style, the higher the Cost must be. Considerations of 1) Performance, 2) Style, and 3) Cost, send our personal choices in the directions that suit us as we individuals deem best. Those choices have nothing to do with the taste of anyone's Kool Aid. I have already acquired a high duty cycle, low distortion, 1.5KW amplifier years ago. Now I would like a small, light, and portable HF+6-meter amplifier for DXpedition duty.

Re: [Elecraft] News from Visalia!
On an empathetic note... Can Elecraft come up a price-appropriate tuner design that will survive hams at 500 watt RTTY? In the midst of trying to concoct a remote home brew tuner to put 160-30 meters on a 135 foot end-fed wire, the calculator and equations starting telling me that voltages and currents that would have to be switched under power could run over 10 kV or 20 amps, depending on frequency, at 1.5 kW. IF there were a bullet-proof, ham-proof way of insuring that contacts were NEVER, EVER switched under power, some things could be done. But I can't figure out how to keep ME from doing that when I'm really stupid at the end of a contest. There is a point at which bulletproof tuner designs seem to warp into an entire new expensive component universe. Depending on the engineer and personal or commercial risk tolerance, and whether that might be RTTY or not, that power level is 200-400 watts. After that you are talking Collins Radio kind of commercial/military grade designs with motors, vacuum relays and capacitors. Less than that and one is frying stuff that is perfectly satisfactory at 200-400 watts. The commercial risk is obvious. Burned contacts will always be blamed on the manufacturer. If he can't design something that can't burn, for a price a customer is willing to pay, what's the point. Go out and price a pair of motor driven vacuum variable capacitors big enough to cover the variation on 160m and with the voltage rating to stand up to tuning antennas at voltage nodes. Gak. Sigh. Kind of like the sound barrier, not impossible but definitely a new mode beyond it. The one possible work-around is an Elecraft tuner that will not work unless hooked up to an Elecraft amp and a Kx via proprietary protocol so it knows whether it is QRO or not and can seamlessly drop out of QRO for tuning. Something like how the K2 and the KPA100 work. 73, Guy.

That ATU doesn't have to come from Elecraft, though. LDG has certainly made automatic tuners that work with Icom's (more or less undocumented) tuner protocol, even making model numbers sorta match i.e. AT-7000. 73, doug back home again, CA 198 to CA 25 to slab. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

"Sounds trivial to me. You must have *some* switch closure or logic signal that activates the PA. Lock out all tuner adjustments when the PA is on." Or conversely, disable the amp before tuning starts. That's the way my MFJ-998 autotuner works. The amp-enable signal goes thru the MFJ-998. So when the tuner wants to tuen, the first thing it does is interrupt the amp-key line.

Re: [Elecraft] News from Visalia!
I am building up such a linear amp 12w --> 200w on 2-30 MHz. If it tests out well, I am thinking their may be a market for this. I understand that the FCC has to accept the unit, but I wonder if it is only available as a kit if that applies? This is a 28-volt transistor so a 28 volt 20A supply is needed>>> Kits and parts kits, even when incomplete, have to be certified. For some reason the FCC has allowed the CCI kits to slip by but even at Heathkit, once type acceptance came into play, things had to go past the FCC. It's a big deal to do a certification filing. Just follow the rules outlined by the FCC. Gain limit is 15 dB, there are harmonic and spurious specs, and no amplification or easy modification for operation between 26-28 MHz. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

Re: [Elecraft] News from Visalia!
The 15 dB gain limitation made more sense when Part 97.317 included a companion restriction of requiring not less than 50-watts drive power to attain the amp's rated output power. If a Part 95 user had the wherewithal to somehow modify a recently manufactured QRP-input type amp, 15 dB still places a 4W Part 95 transceiver at roughly 140-watts AM, 400W SSB (Part 95.410). Part 97.317(a)(3) already states: "no amplification (0 dB gain) between 26 MHz and 28 MHz." I believe the gain restriction could be dispensed with, and the remaining sections of 97.317 kept intact -- and little detriment would occur. As to HF amp kits requiring certification, I see no dispositive section in the CFR that affirmatively compels certification of a kit for use in Part 97 service. Section 97.315 clearly discusses "manufactured and imported" amplifiers -- kits are not specifically included in the rule. However, there may be relevant case law on the matter that backs up the CFR -- and the FCC may have invoked internal policy decisions in the past, but someone could create an argument that if the FCC had wanted to compel certification of HF amp kits, they could have easily done so and that requirement should have been implemented as a matter of procedure under the APA. The argument can be further bolstered under Part 97.315(a)(1) which states amplifier certification is not required if: "...the amplifier is constructed or modified by an amateur radio operator for use at an amateur station." Does the term "construction" mean home-brew only with parts secured on-hand and through multiple vendors? Or, does construction also mean "in kit form," where the parts are consolidated for sale? The question is then: how does one interpret the exact rule of law? The "in kit form" term could have been easily defined and included in Sections 97.315 and 2.815, but it isn't. If the government intends to prohibit something that's simple to read and interpret, they need to codify it in a rule and not leave it to guess work. Other means to get the FCC's position on the matter can take the form of form of a Declaratory Ruling or Advisory Opinion.

Re: [Elecraft] News from Visalia!
Eric: The term "kit" has indeed been omitted from the rule. I had to take another look at the rule and track the changes of the CFR. Before mid-2006, Section 2.815(b) had read: "(b) After April 27, 1978, no person shall manufacture, sell or lease, offer for sale or lease (including advertising for sale or lease), or import, ship, or distribute for the purpose of selling or leasing or offering for sale or lease, any external radio frequency power amplifier or amplifier *kit* capable of operation on any frequency or frequencies between 24 and 35 MHz." Then, in 2006, in addition to other changes affecting the rule, the word "kit" was omitted and as of today, Section 2.815(b) reads:"(b) No person shall manufacture, sell or lease, offer for sale or lease including advertising for sale or lease) or import, ship or distribute for the purpose of selling or leasing or offering for sale or lease, any external radio frequency power amplifier capable of operation on any frequency or frequencies below 144 MHz unless the amplifier has received a grant of certification in accordance with subpart J of this part and other relevant parts of this chapter..."That said, want to start offering the KPA500 as a kit? .

Re: [Elecraft] News from Visalia!
Yup - I read the same section again this morning. My discussions with them have indicated that they now consider 'amplifier', as referred to on their rules, to encompass any amplifier - kit or built. We'll be offering the KPA-500 both ways. (FCC Certified.) 73, Eric WA6HHQ On 4/19/2010 11:00 AM, Paul Christensen wrote: > Eric: > > The term "kit" has indeed been omitted from the rule.

Re: [Elecraft] News from Visalia!
Yes, good questions. If a tuner is in the works please have the amp automatically bypassed when a tuning cycle takes place.
