[Elecraft] K3 S-Meter
Greetings, Correct me if I am wrong, but I would think that once you place anything in between the K3 and the antenna, the K3 will see this extra piece of equipment. Whilst all these accessories claim to present 50 Ohms to the transceiver, they place in the fine print that this is a nominal figure and not necessary accurate. If I was using the LP-100 in line device I would expect the K3 to notice it's presence and therefore I would expect some differential between the LP-100 reading and the K3. From the readings posted previously being K3 = 1.1:1 and the LP-100 reading being 1.04:1 then I think enough said. The above observation assumes the K3 has the ATU turned OFF. 73's Gary K3/100 Birth Marked: 679 I just got lost in thought.

Re: [Elecraft] K3 in Carry-on Luggage
I went to Bonaire NA and participated with the PJ4E Group in the 2008 CQWWSSB Contest. I took my K3 and accessories in a hard-shell Porter brand carry-on case. This is a excellent case, has wheels and handle for pulling along, and it will fold down to accommodate other cases to be on top as you pull it along. Great for having to go from one end of the airport to another for your gate. I beforehand took it to a place who foamed to fit all pieces in the case. I found not too much difference in the US airports than the airports in the Caribbean. Some asked what it was, some had enough experience to know or ask if it was Ham Radio equip. It was dusted once on return to Miami. I was told that was because I failed to place it in a rubber tub alone that time. Go figure. However, the airport security people in all cases were polite. The biggest hassle for me was to unload all the gear into the separate tubs, and as well my personal items, trying not to hold up the line behind me. But the way the world is now, it is a necessary thing in order to protect us. My K3 performed magnificently in the contest.

Re: [Elecraft] K3 in Carry-on Luggage
I travelled internationally with my K3 back in 2007 as carryon. I had the K3, power supply and some cables in a case that fit under the seat. No questions asked, nothing removed or demonstrated. I have also travelled internationally with my KX1, no questions asked. Just remove the batteries as I think that there is some restriction on carryon batteries or something like that.

Re: [Elecraft] k3 SWR readings seem generous
This thread came at the right time. I have just finished re-calibrating my LP-100A. I did this after having used the unit for 6 months, however the calibration was very close to the original settings. Then I thought that I would check my K3 SWR indication. The results are not as good as I would expect. I set the K3 with a tune power of 10W, representing the level of power one might use to adjust an ATU. The measurements I made were using 2 x 8 inch lengths of RG8U from the K3 into the LP-100A coupler, and then from the coupler into the dummy load. The dummy load is a precision 100W one which I measured with a VNA and has a VSWR of 1.03 from 1 to 30 Mhz. To simulate a 2:1 VSWR I used another dummy load (not quite as good) in parallel. The K3 output was from ANT1 using the internal ATU. The ATU was automatically tuned to 1:1 on all bands. The results I got for 2:1 VSWR are as follows:- LP-100 K3 160 1.991.8 80 1.991.8 60 1.991.8 40 1.951.8 30 1.971.6 20 1.971.4 17 1.971.3 15 1.961.2 12 1.961.5 10 1.961.4 As can be seen my K3 SWR indication constantly under reads. However, it really gets bad on 20,17 15. I will be interested in the results of others conducting similar tests. 73 Stewart G3RXQ On Thu, 1 Jan 2009 17:47:04 -0800, Mike Scott wrote: I have been working on antennas today and have a puzzle. I am finding that the K3 SWR indications are unbelievable generous. With my 40M inverted V fed with RG8X (50 ohm) coax I see that the K3 seems generous in the SWR indication on tune with ATU bypassed. I have noticed a slight change in SWR with K3 power setting so the following was taken with K3 tune power set to 100 watts. If I set it to 10 watts the discrepancy is greater... SWR SWR SWR Freq.

The VA1 is the Autek Rx Vector antenna analyzer. The VA1 does not have a tuned input so it is possible that it can be fooled by local broadcast stations. I don't suspect this issue here as there aren't any close by broadcast stations that I am aware of. The Daiwa and the VA1 tend to agree pretty well anyway. The K3 measurements are the outliers. This antenna on a Tenna Dipper shows minimal SWR at 7.040 MHz, just where I tuned it a few years ago. The LED does not extinguish indicating higher than 1:1 SWR at the minimum. If you look at the numbers, I guess I don't believe the K3, Do you think my antenna is below 1.6 to 1 across the entire 40M band? So now on to 20M dipole fed with RG58 (50 Ohm Coax)... The Tenna Dipper fully extinguishes at 13.805 MHz indicating that my antenna is bit too long but is close to 1:1 at that frequency.

The dipole is a low one and probably isn't 72 ohms at the feed point.

Re: [Elecraft] Order of assembly K3 Options
Gary, The main receiver KBPF3 mounts under the KRX3 assembly, so you would want to install that first. The others can be installed in any order. In any case, it is not difficult to remove the KRX3. In fact it can be lifted out of the K3 by removing only the 2 screws and the TMP connector for the input antenna (the other TMP cables can stay plugged in) 73, Don W3FPR Gary Smith wrote: I ordered the KXV3 with the K3/100 to assemble at the time of purchase but it was back-ordered at the time of shipment and it arrived this week. I have the KRX3 on order and it will be ready for shipment fairly soon. I am going to order the KBPF3 general coverage module and the 1ppm KTCXO3-1 TCXO module to be sent asap if they are in stock. I found some of the connectors resistant to insertion when putting the K3/100 together. For instance; the ones where you needed to use your thumbs under the RF board to prevent the board from twisting during insertion; I had to use a fair amount of force to get these sockets fully engaged and they usually went in with a snap. Indeed all the pins were full mated and all assemblies installed 100%. Considering the deliberate latching when inserted, these connectors are re-assuringly secured in place but I remember thinking to myself, 'I do not look foreward to removing them when I wish to add another module.' So I don't want to keep removing and replacing parts back there. There is one port in the back marked REF, which now has a plastic plug in place. I don't know if the connector that goes in there is part of the sub receiver as no such connector is with the KXV3 and I seem to have missed mention of it with the assembly of the K3/100 but it looks to be tucked in a freely in-accessible area so perhaps it is part of the RX sub? I'd like to install the KRX3 asap but will hold off if I need to remove the boards above the REF port. So from those of you with experience in installing these modules in an already assembled K3/100, in which order should the following modules should be installed so I do not have to remove reinstall these various strip connectors more often than necessary? Again, the modules to be installed at this point are: KXV3 (now at the QTH ready for installation) KRX3 (on back-order) KBPF3 gen coverage (to be ordered asap) 1ppm KTCXO3-1 TCXO (to be ordered asap) ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] Distorted TX audio with RTTY decode enabled
I just about went crazy finding this one last night. I've got two K3's @ N3HBX running 2.67 and 2.73 and both have the same problem. Setup is Data/AFSK A and 2125/170. With the K3's RTTY decoder function enabled so it displays running text on the front panel, intermittent distortion is introduced into the TX AFSK audio, usually when set above a certain level. Actually, one of them had it at any level and the other would only kick in once the input level reached a certain level. With the decoder turned off, it does not exist at all. To describe the noise, it's like a high-frequency burping or buzzing noise. See also unflat audio response in separate message. Suggestions or confirmations?

[Elecraft] Quick Memory operation
I'm a new owner of a K3 and am still learning its operation. At the moment, it's not fully incorporated into my station, but is side-by-side with my Kenwood TS-870 for some comparison/familiarization. A few minutes ago I was on 80-meter CW listening to JD1BLY working a mini-pileup. He was barely above the noise on 3502, listening up 2. I was A/B switching the two radios. I decided to tune around and come back to him just before my sunrise. I set up the split on both radios, hit M-IN on the '870 and V - M and M4 on the K3 and did some more tuning around. A bit later while listening on the Kenwood, I hit MR and noted that JD1BLY was now S7. I switched the antenna to the K3, pressed M - V and M4 and gave him a call. My reply was an S9+20 L I D, since the fact that I needed to operate split wasn't memorized (or recalled---I'm not sure which) and I dropped my call on his frequency. I've searched the archives and FAQ but still have the question, am I missing something (highly likely), or does the K3 fail to memorize split setups? If so, why?

RE: [Elecraft] k3 SWR readings seem generous
However, the Gap SWR is around the 2.3:1 range when the K3 (or PW-1 tuner) reads about 1.5:1 or less. I then realized it was showing me the real SWR, not the tuned SWR. I think I am correct in this assumption. John, your understanding is correct unless the K3 ATU is in bypass mode which it was for my tests. The K3 then should be measuring the feed line SWR because there is no tuner in the circuit. Also I used tune mode which shows the digital readout of SWR, not the number of bars on the SWR readout. So try it with the K3 tuner bypassed and see what you get.

RE: [Elecraft] k3 SWR readings seem generous
I don't think so. The K3 tuner is in bypass. The LP-100A is next in line, followed by the tuner (no amp yet) followed by the fan dipole. The tuner is showing the tuned SWR. The LP-100A sees only the tuned SWR and the K3 tuner is off so it should see the same thing that the LP-100A sees. The LP-100A and the tuner generally agree (the LP-100A is digital and the tuner uses crossed-needles, but it's close).

The K3 tuner is making the K3 see 50 ohms. The LP100 is telling you the actual SWR that exists prior to the K3 tuning it to the 50 ohm. I have the LP100 using it with a SteppIR BiggIR vertical and also a Gap Voyager vertical for 160m and 80m. The LP100 reads around 1.04:1 on the SteppIR on 40m as does the K3 (shows 1 bar), which is close to what my old Diamond meter use to read. However, the Gap SWR is around the 2.3:1 range when the K3 (or PW-1 tuner) reads about 1.5:1 or less. I then realized it was showing me the real SWR, not the tuned SWR. I think I am correct in this assumption.

I am finding that the K3 SWR indications are unbelievable generous. With my 40M inverted V fed with RG8X (50 ohm) coax I see that the K3 seems generous in the SWR indication on tune with ATU bypassed. I have noticed a slight change in SWR with K3 power setting so the following was taken with K3 tune power set to 100 watts. If I set it to 10 watts the discrepancy is greater... SWR SWR SWR Freq. K3 VA1 Daiwa 7.00 MHz 1.3 1.922.0 7.05 MHz 1.2 1.921.9 7.1 MHz 1.2 1.981.95 7.15 MHz 1.3 2.262.1 7.2 MHz 1.9 2.602.3 7.25 MHz 1.5 2.882.6 7.3 MHz 1.6 3.322.7 The Daiwa is the CN-101L cross needle meter. The VA1 is the Autek Rx Vector antenna analyzer. The VA1 does not have a tuned input so it is possible that it can be fooled by local broadcast stations. I don't suspect this issue here as there aren't any close by broadcast stations that I am aware of. The Daiwa and the VA1 tend to agree pretty well anyway. The K3 measurements are the outliers. This antenna on a Tenna Dipper shows minimal SWR at 7.040 MHz, just where I tuned it a few years ago. The LED does not extinguish indicating higher than 1:1 SWR at the minimum. If you look at the numbers, I guess I don't believe the K3, Do you think my antenna is below 1.6 to 1 across the entire 40M band? So now on to 20M dipole fed with RG58 (50 Ohm Coax)... The Tenna Dipper fully extinguishes at 13.805 MHz indicating that my antenna is bit too long but is close to 1:1 at that frequency. FreqK3 VA1 Daiwa 13.81 -- 1.12-- 14.0 MHz1.11.241.31 14.1 MHz1.11.301.70 14.2 MHz1.11.551.85 14.3 MHz1.21.691.85 RG58 may have some losses on this band so perhaps all of the SWR indications are generous, some more than others. The dipole is a low one and probably isn't 72 ohms at the feed point.

[Elecraft] Re: k3 SWR readings seem generous
Michael E Fox (N6MEF) wrote: My factory-assembled K3 is reading 1.0 SWR while my LP-100A and tuner both agree on about 1.4-1.5. The KAT3's stray impedance (in bypass mode) may impact the SWR as seen by the K3's bridge, since this bridge is between the ATU and the LPFs. This effect would be more pronounced on the highest bands. Your external bridge is between the KAT3 and the antenna, so it may read differently from the K3 if any strays are present. The bypassed state of the KAT3 is actually a per-band combination of L and C intended to cancel out the ATU's own strays. But compensation accuracy will vary from one KAT3 to the next due to the 5% tolerance on the components. So on some bands, the SWR in bypass mode might actually look closer to 1.0:1 with a load Z that is not quite perfect. Still, all of these effects should be small, and I'll do some tests to see if I can duplicate an SWR discrepancy between the K3 and an external instrument. 73, Wayne N6KR --- http://www.elecraft.com ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] why the K3 is my favorite rig
Recently, there was a post on the FOC reflector to the effect that the FT2000 is a superior choice to the K3. Much of the criticism of the K3 centered around the size and heft of the rig, as well as the cost. Here are my thoughts on the subject: Amateur radio is a diverse hobby with a diverse population of operators. It's unlikely that one rig can fit all, or even dominate a market. The way I see it, the K3 addresses a segment of the market that values high-performance. This includes, but is not limited to, contesters and DXers. As it happens, contesters and DXers make up a relatively small segment of the overall amateur population (though we are often the most vocal group!) Still, there's plenty of money to be made from this small segment because its constituents tend to commit considerable resources to the hobby (money, land, towers, antennas, time, and electronics.) Many of us are on a never-ending quest for that last 1 dB of antenna gain, that last bit of S/N, that last bit of selectivity, etc. Some of it is driven by competition (we don't like missing a weak station or losing out in a pileup), and some of it seems to be a perfectionist streak common to many contesters and DXers. Also, I think K3 fans tend to be somewhat more technically-oriented than others in the market. And I think some of us are getting old and our ears need all the help they can get! I've used quite a few rigs over the past 25 years, and none of them has pleased me as much as the K3. Yeah, I liked the Drake twins, but keeping them tubed, aligned and operating properly was a chore, and the lack of features and flexibility would drive me crazy nowadays. Most of the rigs I've used suffered from poor selectivity (a choice between shallow filtering or ringing) and poor IMD rejection. Of the previous generation of rigs, the Yaesu FT-1000D and Icom 781 are probably the best I've used for contesting, but still suffer from those problems. Also, they're big, heavy, take up a lot of desk space and generate a lot of heat. Neither is particularly flexible. Neither is practical for the owner to repair, and spare parts are becoming hard to find. The Orion was the first rig really able to deal with ultra-crowded bands and challenging propagation conditions. The combination of roofing filters and DSP filtering makes an incredible difference. The rig is very flexible, too. The box is large enough to look serious, the screen is large (in color on the O-II), and the knobs/buttons are large enough for most operators. Unfortunately (or fortunately for Elecraft), Ten-Tec designed the rig without asking customers what they wanted, and wound up with one of the worst user interfaces on the market. Some contest station owners won't let an Orion in the door because the learning curve for new ops is too high. To compound the matter, the firmware is poorly designed and poorly implemented. Some of the original performance of the radio has been lost in so-called firmware improvements. Since those were introduced several years ago, the firmware has not been updated at all. The hardware itself is fairly reliable, but there are a number of areas where substandard components were used and they tend to fail over time (encoders, relays, etc.) When I first opened my Orion, I was amazed and somewhat disappointed by the large amount of empty space inside the chassis. I thought, What a waste of space!. As we know from our K3 experience, Ten-Tec could easily have fit the circuitry in a much smaller box. I suspect they made the choice for a larger box based on the screen size, number of buttons and knobs, and a desire to make the radio look serious. I understand that the K3's form factor might mislead the casual observer to think that the radio is not serious. This is clearly more of an issue with the observer's psychology than the K3's capabilities. Marketers do have to pay attention to buyer psychology, but they don't have to cater to the lowest common denominator if there are enough other buyers in the market with different psychology. I guess I'm one of the latter. The K3 is by-far the best and most capable HF radio I've ever used, and I really don't care what the package looks like. In fact, I've come to appreciate the small form factor -- it takes up very little space on my desk and it's much easier to get the radio out of its operating position and onto the workbench for upgrades and mods. I haven't taken it to another station for guest operating, but based on my previous experience lugging a 1000D and an Orion, it'll be a pleasure to take the K3. I can't see how the K3 could fail to become the DXpedition radio of choice -- this is where the small form factor is worth gold. The K3 has another advantage that may have been overlooked by appliance operators: there's no other full-featured, high-performance HF rig that you can buy in kit form. To me, the value has not been so much the cost saving, but the opportunity to understand how the

RE: [Elecraft] KRX3 and KDVR - Installation Sequence
Dick's suggestion is excellent. You can stop and confirm your KDVR3 is working after you remount the K3 front panel and before you install the rest of the KRX3 (which goes inside the main K3 enclosure). Just don't enable the KRX3 in the MENU. The K3 will ignore the Aux DSP board you mounted in the front panel assembly until you do. Remember, you must install new firmware for the KDVR3! You must have at MCU ref 2.73 or later.

Re: [Elecraft] why the K3 is my favorite rig
Hi Dick, Enjoyed reading your posting. I'm not a contester (yet) and my QTH prohibits chasing DX - but I do agree with the points you make, in particular the one about the compact nature of the rig. We annually run a trip up to the Scottish islands and size really does matter. We have to get as much stuff as we can in to as small a number of vehicles as possible to keep the cost down. The K3 is ideal for this purpose as it has all the performance needed in a relatively dinky box. We've tried smaller radios such as an IC7000 and FT857 and while they take up less room they struggle with some of the pileup's and the incoming signal strengths that our beach located antennas generate. On a slightly humorous note, this year one of the op's brought his FT1000D along and the most risky part of the trip for me was unpacking it and packing it away again (manual handling injuries anyone?) - it is a fine rig though. We're fortunate enough, now, to have access to a contest and field day site that overlooks the sea so I'm looking forward to having a bash at some contests with the K3. 73 Paul M1PAF -- View this message in context: http://n2.nabble.com/why-the-K3-is-my-favorite-rig-tp2103444p2103631.html Sent from the Elecraft mailing list archive at Nabble.com. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Installing the KDVR3 is a nothing once the front panel is out and apart, tiny board, one plug, one screw.

[Elecraft] why the K3 is my favorite rig
Well, Dick Long ago, I gave up trying to understand why some folks choose the things they choose. If you think back to the 60's or 70's, you could NEVER convince a Mustang owner that Ferrari was the way to go... or vice-versa. Some men like women who LOOK hot. Some men like women for personality/brains. If you can find one with both...WOW! When the Orion 1 came out, I thought it was the butt-ugliest rig I had ever seen...but I respected the specs. With OII, they gave in to the demand for a color screen, but it was still butt-ugly. LOL. When the programmer left, I stopped reading the TT mail entirely. Too bad. TGI Elecraft! It sure doesn't LOOK like a 7800, but boy does it play! Most of the time, when I use a radio, I'm not admiring its looks. But maybe that's just me. I've heard of a trophy wife...maybe some guys want a trophy rig. But the K3 is no last one at the bar either. Cost? I thought the K3 was INEXPENSIVE for what you get...still is. Compare to $10 or $12K NO brainer. If these FOCers are contesting, I hope they love their FT2000...cuz Ill run rings around 'em with the K3.

RE: [Elecraft] why the K3 is my favorite rig
A very obvious next act for Elecraft would be to repackage the K3 in a larger box, add a bit-mapped color screen, add a few more buttons, make the knobs larger, and perhaps include an internal power supply. Voila: the K4! I'm sure many (not me) would pay $5K or more for such a radio, provided the hardware looks and feels expensive. If this idea is rattling around in the minds of our Elecraft wizards, my advice is to focus on the cosmetics and resist the urge to make lots of improvements. I agree ... however, I would strongly encourage a K4 to include a dual voltage power supply and higher voltage PA transistors to improve transmit IMD (and perhaps provide 250 watt output). Although the K3 has ye to be beat in terms of raw performance, a K4 (K3D?) with better PA, built-in panadapter and perhaps dedicated band buttons with band stacking registers would be a very serious challenger to the $10K class toys. 73, ...

[Elecraft] K4: serious challenge for the $10K toys
Hi Joe... Yes, I'm sure a K4 (or how about a K88 so the SE Asia guys would buy in big time) could be easily made. In fact, for that group, it might make sense to price it even higher than theirs...say $15 or $20k. You know, when you get into the upper tiers of any market, it's the HIGH PRICE that convinces folks that it's good. And if it really is good (as I'm sure the K88 would be), then bingo. Tons of profit marginwith a concomitant lower volume. It all balances out. However, if you look at the track record of Elecraft, they appear to be very good at identifying very tiny niche markets (although the K3 seems to have a wide appeal...wider than expected?). Somehow, competing head to head with a big radio doesn't seem to fit the Eric/Wayne approach. As I recall (it's probably on their web site somewhere), the K3 was targeted to be a high performance, very portable, light weight radio...with some very neat features too. They have certainly achieved that. If I were them (which I am not), I'd be focusing on refining what I have (which they are obviously doing). It is probably just a matter of time before the FT9009 and IC7878 come out, using nearly identical receiver design approaches to those used in the K3 (and Orion). Citing my own previous post today, this could be the Trophy wife with four PhD degrees. It's got to be only a matter of time. Of course, it will still be a BIG, HEAVY radio, taking up lots of real estate and providing lots of future opportunity for Herniorrhaphy surgeons. The K3 will still have its niche market.

[Elecraft] cw to psk
Hello Group, Need a little help with the cw to Psk on the K3. I can transmit with the paddles but only get a steady tone. If I hit M2 I send cq and can hear the psk tones. I must be looking at something I didn't set. Listen on another rig and only a stead tone. have it in data mode selected Psk and I see the small T below the data icon.Also have the key plug in the paddle jack in the rear. Any ideas? Don..w2xb P.S. no problem sending psk or data with the soundcard and MixW. -- View this message in context: http://n2.nabble.com/cw-to-psk-tp2104545p2104545.html Sent from the Elecraft mailing list archive at Nabble.com. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] cw to psk
Don, I just tried it and it works fine for me - whether the Test Decode (small T) is on or off, it works FB. Any chance that you are first tapping the 'XMIT' button? If so, don't do that - just hit the paddle and go. You should see the message you entered with the paddles displayed in the VFO B area. 73, Don W3FPR W2XB wrote: Hello Group, Need a little help with the cw to Psk on the K3.

RE: [Elecraft] why the K3 is my favorite rig
... however, I would strongly encourage a K4 to include a dual voltage power supply and higher voltage PA transistors to improve transmit IMD (and perhaps provide 250 watt output AMEN Joe!!My thoughts exactly. Bigger box, same RX performance, more buttons, less menus, better band switching accommodation for non-amateur frequencies, an internal higher voltage power supply and an output power of 200 W. I do low power contesting and would REALLY like a rig that can loaf along at 150 W. I know that it is only an additional 1.5 dB or so over the K3, but every little bit helps. I can't really justify buying an amp to go from 100-120 W to 150! 73 and HNYCraig AC0DS ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] Isolation between Ant 1 and 2??
Hello and Happy New Year!! Was doing some testing and discovered Ant 1 signal on Ant 2. Ant 1 is my GAP Titan-DX and Ant 2 is a 100W dummy load. I was just reading the mail on 75 meters and switched to Ant 2 to test power. When key was off, I heard part of the QSO that was going on. While on my dummy load, I was receiving a station S3, which on Ant 1 was 20 over S9. Has anyone else seen this crosstalk? If so, what is considered acceptable? -- 73, Dick ka1oz Middleborough, MA Radio: Elecraft K3/100(Kit) SN 859 Antenna: Titan-DX ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K4: serious challenge for the $10K toys
Hello Doug, For the market of 10k and 15k rig, it has to be supported by a large institutional market which is the most profitable. The requirements from institutonal users could be different from hams. Durability, physcial strength and easiness of operation could be another areas to look into. I fully appreciate that Elecraft is a very clever manufacturing engineer and marketing manager. When you examine both K2 and K3, for all the non-essential parts (including the fat head and pan head cabinet screws), I am rude to say that they use the cheapest materials. For the T/R switch of KPA100, they only use the cheap IN4007 diodes for the switching (but works very well!!). On the other hand, for the criticial parts such as the front end of XV144 they use an excellent MOSFET. Elecraft is very clever in a way that they can mimize the production costs against performance. K2 and K3 are excellent in specifications but I doubt whether they can really operate under full institutional usage 7/24 a week. May be there is another version of K3 for institutional users which I don't know. I am an ICOM user as well. I understand that ICOM earns huge revenue from the institutional version of their IC7800, IC7700 and ICR9500. For a purchase of 10k or over, the prospective purchaser will look into other issues. For me, I would also think of resell value of my used gears if I invest 10k or more. May be I am lucky that in Hong Kong, all the top gears (except K3) are only 80% of the US prices. Therefore, when I sell my IC7800 or IC7700 in future, the loss to me could be minimal. With the clever minds in Elecraft, I think they have the capability and talent to enter the profitable institutional market. Perhaps, they may go for IPO in due course (of course not now) for funding. cheers, Johnny Siu VR2XMC --- 2009年1月3日 星期六，DOUGLAS ZWIEBEL doug...@gmail.com 寫道﹕ 寄件人: DOUGLAS ZWIEBEL doug...@gmail.com 主題: [Elecraft] K4: serious challenge for the $10K toys 收件人: Elecraft Reflector elecraft@mailman.qth.net 日期: 2009 1 3 星期六 上午 10:57 Hi Joe... Yes, I'm sure a K4 (or how about a K88 so the SE Asia guys would buy in big time) could be easily made. In fact, for that group, it might make sense to price it even higher than theirs...say $15 or $20k. You know, when you get into the upper tiers of any market, it's the HIGH PRICE that convinces folks that it's good. And if it really is good (as I'm sure the K88 would be), then bingo. Tons of profit marginwith a concomitant lower volume. It all balances out. However, if you look at the track record of Elecraft, they appear to be very good at identifying very tiny niche markets (although the K3 seems to have a wide appeal...wider than expected?). Somehow, competing head to head with a big radio doesn't seem to fit the Eric/Wayne approach. As I recall (it's probably on their web site somewhere), the K3 was targeted to be a high performance, very portable, light weight radio...with some very neat features too. They have certainly achieved that. If I were them (which I am not), I'd be focusing on refining what I have (which they are obviously doing). It is probably just a matter of time before the FT9009 and IC7878 come out, using nearly identical receiver design approaches to those used in the K3 (and Orion). Citing my own previous post today, this could be the Trophy wife with four PhD degrees. It's got to be only a matter of time. Of course, it will still be a BIG, HEAVY radio, taking up lots of real estate and providing lots of future opportunity for Herniorrhaphy surgeons. The K3 will still have its niche market. Okay..end of make-believe I can see the future diatribe. :-) de Doug KR2Q ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] [K3] Constant Level Line Out with Monitor
Hi and Happy New Year 2009! I just wondered if anyone got a suitable way having both Headphones and Monitor audio with a constant level on LINE OUT jack in order to record a 48-hour contest, for example? Setting LIN OUT to PHONES just does the trick but the RX audio level is controlled by the AG gain knob of the front panel which is really annoying in a Multi-Op Contest Team where nobody listen at the same level. Doing that way makes some part of the recordings quite low and some others distorting! I think lots of contesters would appreciate to have an option in the K3 for having the RCV and the XMT audios both with a fixed level on the Line output. 73, -- Olivier / f5mzn ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
