Re: [Elecraft] K3 6-meter Performance Question
I have just finished putting together, and testing a 6m preamp kit from Down East Microwave. As I use the RX Ant input on the lower bands, and not wanting to put in a relay, I have made up a Diplexer to separate out the 2 signal paths. Although the arrangement is a bit of a lash up it has proved the concept, and it's worth during a short 6m opening the other evening. Without the preamp I noticed no discernible different in the K3 noise level when connecting the antenna. With the preamp I get about an S2-3 indication. More importantly signals which were there but not readable, with the preamp they gave 100% copy. I think that my present preamp gain at around 22dB is a little excessive, so I will drop it back to about 15dB or so. Before I get swamped with requests etc, I should stress that my arrangement is not really reproducible, and you should wait until Elecraft releases their preamp solution.

Re: [Elecraft] K3 6-meter Performance Question
Ian, One also needs perhaps 10db of noise headroom for modes like JT65 which copy many db below the noise. My opinion is the an internal option for this preamp is needed. Dangling still another box with the attendent extra cables outside the K3 isn't desirable here. Yes the preamp does handle the LF rx antenna-- still more complication. Perhaps Elecraft can come up with both an internal and external fix and let the market decide. I'd like nothing better than pushing the preamp button and getting a souped up 6M preamp without more external junk. However Elecraft knows the guts of the K3 and perhaps an internal fix isn't practical. At least it would be nice to know that. Of course the best place for a preamp is at the antenna. However, the problems that generates when one is running high power introduces even more complexity. 73 de Brian/K3KO Ian White GM3SEK wrote: On Tuesday, Dick K5AND wrote: Ciao, from CY0X, Sable Island.

Re: [Elecraft] K3 - Squelch question
...Does the squelch not work on SSB or am I doing something wrong? Squelch is currently only active on FM, I believe. You can park on the 6m freq and use the NR to reduce the background noise from SSB. You should still hear all but the weakest signals, depending on how aggressively you set the NR. F1-1 has the least suppression but lets the weak signals through, F1-4 requires the signals to have a moderate S/N. F1-3 may be a good compromise. 73, Lyle KK7P ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

RE: [Elecraft] LINIX PCs and ham SW?
Hello All, Thanks to all who responded to my request for info on ham SW on a Linux PC. From the responses that I've received, I've concluded that a Linux PC would serve my needs for logging and for control of my K2, but not for SDR/panadapter purposes. (My other uses, e.g., EZNEC, etc., aren't as critical as I can run those applications on the family PC when my wife isn't using it). So, it appears that my other option is a Vista PC - and I have the same questions - what ham SW runs or doesn't run under Vista: logging programs, K2 rig control programs, SDR programs, EZNEC, transmission line programs, etc.?

Re: [Elecraft] K3 CW speed request
Dahs are actually twice the length of dits, I think. Or technically, the dah period is twice the dit period (i.e., a dah sound plus its space is equal to two dit sounds and their spaces). I measured the dahs instead of dits because I don't have a keyer; just pluged my mono straight key plug into the paddle jack and it gives dahs. I measured the period by averaging over five dah periods with the K3 readout set at 22 wpm and 21 wpm, giving periods of 0.207s and 0.219s, as mentioned. I measured the sidetone at the headphone jack using audio waveform software. 73, Drew AF2Z On Thu, 03 Jul 2008 07:39:55 -0700, andy, ae6y wrote: Those dashes sound a little long.

The actual overall wpm is set by the sender depending on the timing of the gap between each character and each word.

Re: [Elecraft] K3 CW speed request
Drew, I don't think that is correct. Normal CW has a dash that is three times as long as a dot. If you have dashes as short as twice as long as dots, the code sounds very strange. The ratio, i.e., three to one, is purely of the length of the character. Normal spacing between dots and dashes is one dot length, independent of the dot to dash ratio. If the transmitted code sounds OK, and the dashes are truly as long as you say, then the speed control is mis-calibrated. I note that the K3 has a menu entry for what they call CW Weight, defined as the dot to space ratio (although often CW weight is used to mean the dot to dash ratio). Not sure if there is a way on the internal keyer to vary the dot to dash ratio. Most outboard keyers allow you to play with the dot to dash ratio, and some people like to vary it a bit from three to one. 73, Andy, ae6y. - Original Message - From: [EMAIL PROTECTED] To: Elecraft@mailman.qth.net Sent: Thursday, July 03, 2008 7:57 AM Subject: Re: [Elecraft] K3 CW speed request Dahs are actually twice the length of dits, I think.

[Elecraft] OT: K3 at Faroes (OY) - Bad News/Good News story.
Hallo, In less than 48 hours we (DL6RAI, DL2MLU, DD1LD, DK7MCX, DD5FZ) will be leaving Munich to start our journey to Suðuroy, the southern most island in the Faroe Islands (OY). snip The bad news: Traditional Faroese food: Dried mutton and whale meat and blubber. The Good News: There is PLENTY OF IT. ;-) ;-) ;-) Traditional food Traditional Faroese food is mainly based on meat and potatoes and uses few fresh vegetables. Mutton is the basis of many meals, and one of the most popular treats is skerpikjøt, well aged, wind-dried mutton which is quite chewy. The drying shed, known as a hjallur, is a standard feature in many Faroese homes, particularly in the small towns and villages. Other traditional foods are ræst kjøt (semi-dried mutton) and ræstur fiskur, matured fish. Another Faroese specialty is Grind og spik, pilot whale meat and blubber. (A parallel meat/fat dish made with offal is garnatálg). Well into the last century meat and blubber from the pilot whale meant food for a long time. Fresh fish also features strongly in the traditional local diet, as do seabirds, such as Faroese puffins, and their eggs. Late development: There is no McDonalds on the Faroes, but Burger King has arrived. Mutton Whoppers with blubber sauce - for those brave DL's, and I'll buy just to keep the station running!

I am asking if the speed control resolution could be halved. What everyone really wants to know, Charles, is *why* this is important. It would cause speed changes to be slower, and special care on the part of the programmer to assure precise timing. Timing issues in a radio like the K3 are complicated, because of the asynchronous events which also have to be handled. In addition to the inaccuracy of the keyer, the operator's spacing is highly variable (even if the keyer supports autospacing, which the K3's does not). In my experience a resolution of 1 wpm is quite adequate. I've been a CW operator for 51 years, although I'm not sure how relevant this is.

Mutton is the basis of many meals, and one of the most popular treats is skerpikjøt, well aged, wind-dried mutton which is quite chewy. The drying shed, known as a hjallur, is a standard feature in many Faroese homes, particularly in the small towns and villages. Other traditional foods are ræst kjøt (semi-dried mutton) and ræstur fiskur, matured fish. Another Faroese specialty is Grind og spik, pilot whale meat and blubber. (A parallel meat/fat dish made with offal is garnatálg). Well into the last century meat and blubber from the pilot whale meant food for a long time. Fresh fish also features strongly in the traditional local diet, as do seabirds, such as Faroese puffins, and their eggs.

Re: [Elecraft] K3 CW speed request
On Thursday 03 July 2008 17:09:04 Vic K2VCO wrote: What everyone really wants to know, Charles, is *why* this is important. It would cause speed changes to be slower, and special care on the part of the programmer to assure precise timing. Timing issues in a radio like the K3 are complicated, because of the asynchronous events which also have to be handled. In addition to the inaccuracy of the keyer, the operator's spacing is highly variable (even if the keyer supports autospacing, which the K3's does not). In my experience a resolution of 1 wpm is quite adequate. I've been a CW operator for 51 years, although I'm not sure how relevant this is. So the question is, what's magic about 21.5 wpm? Thanks for the reply Vic. Nearly all my operating is on CW rag chew. The microphone is only plugged in for the Radio Club SSB net. I have ten year's experience of CW operation and I would say that I am still learning. I like to send at a speed that is close to the other guy's speed. I like to send clearly with correct spacing and without too many mistakes so that the other guy can copy well. At my present stage of learning CW I can comfortably send at 21 wpm on the K3 speed control. I am referring to a rag chew that can last up to 30/45 minutes. I do not know what overall speed I am sending at and it is not necessarily relavent to this discusion. There are days when I can send well at 22 wpm on the K3 speed control and meet the above requirements to ensure that I am sending clearly and in a way that the other guy can copy well. However, there are days when the K3 speed control of 22 wpm is too fast and days when the K3 speed control of 21 wpm is too slow. On those days I would like to be be able to set the K3 speed control to 21.5 wpm. There is nothing magic about this :-) perhaps one day I shall find the need for a K3 speed control of 22.5 wpm :-) Perhaps the reason why I have this problem with the K3 speed control is because until I started using the K3 internal keyer I have always used the Logikeyer from Bob Locher. I hope that I have described my situation adequately and that I have now clearly explained the reason for my request for a finer resolution on the K3 keyer speed control knob.

RE: [Elecraft] [K3] VFO fine-coarse tuning
The problem is that if you changed the tuning rate when not at a .000 setting and the system automatically put you on a .000 setting, the rig would change frequency by that amount, either xmit or receive! Normally you'll be going from fine to coarse, so one would expect that you'd not care about the digits you're hiding or the offset they represent since you're hiding them. But, with today's tendency for some Hams to channelize, for example routinely assuming that SSB stations are on exactly 2.5 kHz intervals across the SSB sub band, it can sometimes result in an apparent tuning error unless you go to the fine rate and correct the offset. One hilarious episode happened to me when I tuned up on 75 meter SSB one morning and signed my call. A station called me back saying I was off frequency. Off frequency? I wasn't in a QSO. I replied and asked him what he meant. He said that I was a few hundred Hz high. High? High from what? You're at 3987.8 instead of at 3987.5 where you belong, he replied. I thought, Oh my gosh!

Re: [Elecraft] OT: K3 and antenna questions
It's temporary, but works fine for now. I drilled 2 holes in the bedroom wall and slid 2 lengths of nylon tube therein, they stick out a few inches outside. A piece of 450 ladder line about 3 ft or so goes from the PL in the rig to a connector block on the inside wall and the 2 wires from outside feed thro to that. Height above ground is about 15ft at this point. One wire goes to the bottom of the garden about 3ft up, then thro a rt angle for about 6ft rising to 4ft or so. The other wire bends at about 80deg and drops to 8ft at the garage barge board, then thro rt angle down between the houses to a tree at the front, about 6ft up. Wire is 20swg SnCu used on several projects. BTW no rf or any other kind of earth on rig. Occasionally hear US 80m ssb early morning. No balun; after initial tuning the K3 remembers its settings and changes instantly on band change. I think I asked it to fine tune on a couple of freqs but can't remember which.

Re: [Elecraft] [K3] VFO fine-coarse tuning
Hi Ron, Channelization is a subject that is beginning to create more and more debate on the air. I must admit that, being a 6m operator where channelization makes sense other than in a contest environment (the band is large -- why QRM each other?), I might have a predisposition in that direction. But aside from the channelization debate, yes, I understand your initial objection. The way to solve that is to simply leave the actual VFO frequency unchanged when pressing the COARSE button -- but as soon as the VFO frequency is moved, drop the offset. Part of my intuitive feeling about this undoubtedly comes from how the TS-2000 was designed to work, and I guess I'm used to that. I don't know about current FT amd IC rigs.

I hadn't thought about it much, but now that I have, I think it may be the intent of the designers to let us switch between Fine and Coarse to speed the movement to another frequency, not to zero out to the proper decimal point. In fact I would find it disconcerting to hear the CW pitch (freq) of the VFO change upon pushing that button. I did notice that if you move the VFO after selecting Coarse the third or second decimal point is dropped, depending on whether you tap or hold. That seems like the best compromise to me.

The way to solve that is to simply leave the actual VFO frequency unchanged when pressing the COARSE button -- but as soon as the VFO frequency is moved, drop the offset. Part of my intuitive feeling about this undoubtedly comes from how the TS-2000 was designed to work, and I guess I'm used to that. I don't know about current FT amd IC rigs.

[Elecraft] [K3] Filter prices
The high prices of the roofing filters for the K3 and optional filters for other rigs reminds me of a little history. In the very early '80s, I desired to purchase a CW filter for an Astro 200, long after CIR went out of business. I happened to be visiting Phoenix, AZ for a few days, so I dropped by Network Sciences, the company that had made the Astro filters and had also been the filter supplier for Drake, Atlas and other manufacturers. It was still there, but obviously about to fold. I met with Howard Falk, the owner, who said he could supply me with an 8-pole CW filter for the Astro. We chatted a bit while a technician, apparently the only other person around, checked out my filter. Howard said that he had essentially been driven out of business by the Japanese filter manufacturers. Drake and others had switched to Japanese suppliers since they could get the filters for a little over $1 each, whereas his cost was over $2 each. Note that there were no middlemen. Drake was selling their filters for $40 or $50 each, I forget which. A tidy profit. Howard charged me $40 for that CW filter, by the way. Since Howard's tale was only one data point for me, it would be interesting to verify it through other sources. Inflation since that time has been about a factor of 2.6, according to official US Government figures: http://data.bls.gov/cgi-bin/cpicalc.pl Some of us would disagree with the official numbers, putting it closer to a factor of 10, but the official factor is close to the actual increase in retail prices for the filters. If the costs have gone up in that proportion, the profits are huge. Especially if one figures in the interim advances in manufacturing, such as monolithic structures, etc. Of course, there is at least one middleman involved with the Inrad filters, increasing the cost to Elecraft. No doubt high markups are necessary along the line somewhere because of the low volumes involved. Nevertheless, I find it especially disturbing having to pay these modern prices considering that the filters have apparently not been designed or chosen for good IMD performance or advantageous group delay characteristics. Also, some filters are reputed to have been defective. Of course, the filters may not be totally to blame for the mediocre front end performance of the K3 (compared with the professional-level performance that some of us had hoped for.)

[Elecraft] [K3] Filter prices
Jerry, I cannot comment on the price level over time even if I have been both in the radio business and a ham for many decades. One can always wish for lower prices, only way to make that happen is by competition which Drake was utilizing. Nobody forces you to buy a K3 with or without filters. I can honestly say that during all my active years I have never listened to a receiver as good as my K3 and yes I do have other rigs as well. The front end at least of my K3 stands up very well in comparison and does handle very high signal levels on the lower bands without any problems. 73 Len SM7BIC The high prices of the roofing filters for the K3 and optional filters for other rigs reminds me of a little history.

The cost of what you pay for distributed goods doesn't just reflect the difference between what the manufacturer sells his product for. There are many other factors involved, like shipping, packaging, employee wages, warehouse rent, taxes, OSHA requirements, city and state regulations, federal regulations and the list goes on and on and on. It just costs money to stay in business even if you never sell anything, you still have to file all the paperwork and pay the fees that allow you to be in business. I'm surprised Mr. Falk didn't just put adds in the ham magazines selling his products for $10.00 each and make a healthy profit, unless he had some sort of agreement not to compete with those distributors buying his products. If his products were equal to the ones sold by Drake, etc., once the word got around, the others would need to reduce their prices or he would capture the after market trade.

My opinion is the an internal option for this preamp is needed. Dangling still another box with the attendent extra cables outside the K3 isn't desirable here. Yes the preamp does handle the LF rx antenna-- still more complication. Perhaps Elecraft can come up with both an internal and external fix and let the market decide. I'd like nothing better than pushing the preamp button and getting a souped up 6M preamp without more external junk.

Re: [Elecraft] K3 Two amplifiers 1 key line
Lee, You should be able to provide control lines for HexFETs or some other kind of switch with just a little bit of logic and the signals from the ACC connector. Look at the Band Data outputs - the only time *both* Band3 and Band1 are at a high impedance state is on 6 meters. A NAND gate (with pullup resistors on the inputs) will give you a LOW output on 6 meters and HIGH on all other bands - call this 'partial band decode'. Now add an inverter to the KEYOUT-LP signal (another pullup resistor is needed at its input) and feed its output to one input each of 2 more NAND gates - the 'partial band decode' NAND gate output feeds the remaining input of one of these NAND gates and that one will have a low output when HF is selected *and* Keyout is active. Invert the output of the 'partial band decode' and feed the inverted output to the input of the other NAND gate that you connected the inverted Keyout signal to - that NAND will have a LOW output when 6 meters is selected *and* keyout is active. I don't know how much voltage and current your amps PTT inputs require, so I leave the final keying of the amps up to you. A pair of the K2 Amp Keying Circuit on the Elecraft website or one of Tom Hammond's K2 Amp Keying kits can be driven by the circuit I described and be used to key your amplifiers. A 74AC00 dip and a 74AC04 will do this task with one NAND gate and 4 inverters to spare - it takes longer to describe in words than to draw it. To be safe, I would not consider letting the RF path determine which amp transmits - if you ever find the ANT1/ANT2 selection changed (by an inadvertent button tap), you could send RF to the wrong amp. You may not be able to simply run the KEYOUT to both amplifiers - that will only work if both amplifiers have the same voltage on their PTT IN lines (measure with your DMM with the amplifier on and nothing connected to the PTT IN jack). 73, Don W3FPR Lee (WW2DX) wrote: I have a HF amp on ANT1 and (soon to be) 6M amp on ANT2. ANT2 is dedicated 6M antenna. Has anyone come up with a way to PTT each amp when on desired band?

[K3] RE: [Elecraft] VFO fine-coarse tuning
I don't feel a big need for the main VFO dial to zero out the insignificant digits, but I would like the first step of the RIT knob, when being used as a fast tuner, to go to the next rounded frequency step above or below. I have noticed that a lot of SSB stations seem to be on exact multiples of 1KHz and this would avoid some need to use the main VFO knob when quickly tuining around. I don't think it's creeping channelization, I think it is just a natural tendency when you have a digital readout and are searching for a frequency to call CQ that you pick a round number to call on. - Julian, G4ILO K3 s/n: 222 K2 s/n: 392 G4ILO's Shack: www.g4ilo.com KComm for K2/K3: www.g4ilo.com/kcomm.html -- View this message in context: http://www.nabble.com/VFO-fine-coarse-tuning-tp18264970p18269048.html Sent from the [K3] 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] [K3] Filter prices
Wow, I wish we could buy 8 pole filters in amateur radio volumes for a wholesale price 1-5$. Or even $30-$40! They just don't exist. (But let me know if you find some..) Our filters -were- designed for their excellent IMD performance. Also, we have these filters tested for IMD and passband response during manufacture. Its always possible one can slip through, but not very often. And the K3 -does- provide top of the line front end performance. Even if you subtract 5-7 dB from our verified lab test numbers at the ARRL and Sherwood you are in the top tier of all amateur rigs. Period. All of the reviewers (ARRL, Sherwood, Radcom etc) have praised the K3 for its top of the line performance. Let's also remember that the IMD dynamic range numbers we are now testing for (95-100 dB+) push the limits of many test lab set ups. Without careful measurement technique and appropriate gear it is easy to confuse the IMD limits of the test set up equipment with the rig. I've personally tripped across that many times here in my lab and have helped others clean up their lab set ups. Also, there are several methods to test IMD dynamic range. (IMD product at MDS, at S5 etc.) With a non-linear device like a crystal filter, the level of test signal is critical for accurate comparisons. It does not act like a transistor amplifier does when subjected to signals at its upper limits. We've seen several folks (including ourselves) test at signal levels way above the max the filter will ever see and then incorrectly try to extrapolate back to IMD performance at expected use strong signal levels. Its easy to get widely varying and inconsistent results when testing that way. But the bottom line is: How does a radio perform in actual use? I'll let our customers past and future postings speak for that. :-) 73, Eric WA6HHQ - Jerry T.

RE: [Elecraft] Re: K3 microphone
I am far from being an expert but here are a few ideas. Make sure you have the front panel mike selected. Press the main button and then rotate the vfo B knob until you come to MIN SEL. Be sure it is set to FP (for front panel). If you are using an electret mike element be sure the bias is on. You can check using the same display. Tap #2 on the keypad to toggle bias on or off. Then be sure the monitor is on and set high enough to hear yourself in head phones. Put the rig in test mode, turn on the vox and speak into the mike while listening for yourself. Adjust he mike gain until you see 4 to six bars on the display. If you don't hear yourself and/or don't have any bars showing at that point, more things will have to be considered. I assume you do have a mike cable wired for the Kenwood standard connections.

Re: [Elecraft] Re: K3 microphone
Gil, You did not say what kind of microphone you are trying to connect. If it is an Elecraft mic, then you will need to turn on the bias - it is turned off by default. If it is a Heil, are you using a Kenwood adapter (and no bias)? If it is some other brand, have you re-wired the microphone plug to match the Elecraft pinout? Do you have the mic gain turned up enough?

Re: [Elecraft] W2MU FD
I operated Lee's K3 this weekend at FD and its truly amazing radio. All the CW ops this weekend at W2MU FD made the same observation on the receiver. All were quite impressed. I ordered mine today and hope I receive by CQWW CW. 73, Ray W2RE Lee (WW2DX) wrote: I took my K3 #464 to FD this year to let a few club members have a real taste of what the rig has to offer. An IC-7000 in the SSB tent and the K3 went into the CW tent. We had a blast, the rig performed flawlessly for solid 24hrs and 1500 cw q's. The remarks were I can't beleive I can hear such a weak signal, The rxer is so quiet!, Best CW rig I ever operated and Where is the buckshot and the QRM? It was great to see the high bands open even 6! Worked CY0X :) I will have some pix and youtube videos up later tonight, just search for ww2dx.

Re: [Elecraft] KRX-3
Hi John, That is inaccurate. We are working to ship by order date independently for the kit and built versions. As per our shipping status page: --- We are now starting to ship against our backlog of KRX3s. We will contact you for confirmation 1-2 weeks prior to shipment. We are now working through the backlog of K3 orders held for shipment until the KRX3 was released, and backlogged KRX3s for K3s in the field. We are shipping in two parallel groups: kit and built K3s. Since -F built K3s are built to order, and because the kit and built versions are built on different production lines, the s/n sequences will not be exactly in sequence between the two groups getting KRX3s. --- There are a lot more KRX3's backlogged for the kit version than for the -F built version, since the initial orders strongly favored kits. We are working through both of these groups in parallel (with different production people) and as a result the -F serial numbers will appear to jump forward faster than the kit versions. Were running as fast as we can. It will take 5-6 weeks to ship all of the current KRX3 backlog. There are a -lot- of them. Its possible a few people may have been notified out of order in the initial rush, but I think I've got that straightened out. 73, Eric WA6HHQ jac wrote: Nope; they do not seem to ship on order date.

Its OK to argue in a polite manner, but please do not jump on anyone personally for stating their opinion. If its out of line I'll jump in and address them directly.

I've build a list of all available menu entries with the possible values. Based on that i will start building a XSD-File. Pls intervene if i am wrong... Next i will check all menu entries against the different firmware level and possible dependencies with the different hardware options. As a result we will have an over all config-XML-File (based on my config... to be extended...) a config-XSD-File and a UserConfig-XML-File which defines the users installed hardware and firmware. Using XSL we should be able to check the entries in a config file automatically. Even a user specific config-XML-file can be generated with this information.

[Elecraft] K3 Beta Firmware Release -- MCU Revision 2.13
K3 beta-test firmware revision 2.13 is now available. Full details appear below and in the release notes. The use of beta-test firmware is encouraged, but optional. Please send any problem reports to [EMAIL PROTECTED] For instructions on how to obtain and load beta firmware, please see: http://www.elecraft.com/K3/k3_software.htm 73, Wayne N6KR * * * MCU 2.13 / DSP 1.83, 7-3-08 New Features: * MEMORY ERASE: During memory recall or store, tapping CLR erases the present numbered memory (00-99) and flashes ERASED. You can rotate VFO A to select and erase any number of memories. * POWER-UP KEY/PTT PROTECTION: If any external device attempts to key the transmitter within 2 seconds of power-up, ERR KEY or ERR PTT will be shown on the VFO B display, and transmit will be inhibited. This applies to KEY IN, DOT, DASH, PTT, vox, or computer-initiated transmit (TX or KY commands). It should prevent accidental transmit during power-on when a computer, keyer, or other device is powered-up at the same time as the K3. Once all keying/PTT/vox activity has stopped, the message disappears, and normal transmit activity can be resumed. Miscellaneous: * RATE, FINE, and COARSE VFO tuning controls are all now saved per-mode rather than per-band/per-memory. * ANTENNA CONTROLS are all now saved per-band, not per-memory. These include: - Main RX/TX antenna selection (1 or 2) - Sub RX antenna selection (MAIN or AUX) - RX ANT in/out selection - Preamp/attenuator settings for RX ANT ON and RX ANT OFF - DIGOUT1 menu parameter setting for ANT1 and ANT2 * PTT RLS MENU ENTRY (PTT release delay). This menu entry allows the the operator to specify a delay from release of PTT to exit from transmit in voice and audio data modes. Not applicable to CW, FSK-D, or PSK-D. The default is 0. A higher value may be needed in ARQ and similar data modes, where the transmit DSP “pipeline” must be fully processed before the carrier is dropped. * NARROW CW/DATA FILTERS (100/50 Hz): Corrected distortion and loss issues. * SYNTHESIZER: VCO CAL improvements related to “ERR VCO” and “ERR PL1” error messages. For software developers: * '$' character in CAT commands targets the sub receiver. At present only the AG$ command is implemented (sub AF gain, e.g. AG$; AG$050;). * FI command provides last four digits of the K3’s exact I.F. center frequency, in Hz. For example, if the selected filter has an offset of 0.00 and is not shifted, the I.F. is exactly 8215000, and “FI;” will return “FI5000;”. * MD COMMAND DURING “TUNE”: For the duration of TUNE, the MD command will return the operating mode that was in effect at the time TUNE was activated, not CW mode. This should fix a problem with third-party panadapters that may have seen TUNE as a mode change to CW. Sub receiver: * KRX3 MENU ENTRY: Settings now include NOT INST, ANT=BNC, ANT=ATU. When the sub receiver is installed, the operator must select one of the two “ANT” settings based on what is connected to the KRX3’s “AUX RF” input: the KAT3’s non-transmit antenna (ANT=ATU) or the rear-panel AUX RF BNC jack (ANT=BNC). * BSET-MODE ANT1/2 ICONS: When the sub receiver turned on, you can use BSET mode to view or change the sub’s antenna assignment: MAIN (sharing the main receiver’s antenna) or AUX (using the sub’s AUX RF input). When AUX is selected, the ANT1/2 icons will either turn off (if ANT=BNC was specified for in the KRX3 menu entry) or one of them will be on (if ANT=ATU was specified). * SUB RX FILTER SETUP: In menus, toggling between RF and SUB and switching filters or modes now properly sets up sub if applicable. This allows the operator to hear the effect of any changes on the sub receiver’s own filters (if SUB AF GAIN is set so it can be heard). NOTE: You must turn the sub receiver ON before entering the menu if you want to listen to the sub during filter changes. --- http://www.elecraft.com ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

I'm trying the initial receiver alignment/test on my KX1. I can hear my transmitted sig from another rig, but nothing on the air.

[Elecraft] K3 Beta Firmware Release -- MCU Revision 2.13
Brilliant! I had to find an undocumented feature to clear Argo V memories. Even though Argo is firmware upgradable they never had time (or took the time) to do that. It is very nice to see real refinement in a transceiver that I already own. I keep looking in the mailbox for a bill, but so far - nothing. ;-) Also highly regard your per mode scenario, and am reasonably sure the CAT FI command will allow the developers of my K3 panadapter software to progress their product in parallel with you. So even more cool K3 related features to come. Don't have a subRX so cannot enjoy the improvements their, but do have a second K3 on order that will be my subRx and it will benefit from all the other upgrades. Even with the rough band conditions there is plenty coming out of Aptos to keep the radio entertaining. ;-) [Elecraft] K3 Beta Firmware Release -- MCU Revision 2.13 wayne burdick n6kr at elecraft.com Thu Jul 3 21:23:55 EDT 2008 K3 beta-test firmware revision 2.13 is now available.

[Elecraft] FW: XV144's TRANSVERTERS NEEDED
Friends, I need four additional Elecraft Transverters to complete my 9 band K3 microwave station and put it into competition in the VHF/UHF/Microwave contests. Ive been using transverters (902, 1296, 2304 3456, 5760 and 10 GHz.) feeding them into an IC-7000 (144 MHz. IF) up until now this has worked out fairly well. Our team has finished in the top 3 rover category in the nation in the past few contests. This past June we had a great score in the new Un-limited rover class and should again place very high. For pictures and soap box go to Waynes, N6NBs write-up at http://www.arrl.org/contests/soapbox/?con_id=154 I would like to be the first (mostly) Elecraft station to win or place very high in the VHF and M/W contests. The ultimate VHF/UHF/Microwave station would utilize the rock crushing filters/DSP in the K3 (needed on mountain tops where high RF is always present) along with 9 XV transverters; XV144, XV222, XV432 and an additional six XV144s that will be used as I.F.s for the other six M/W bands. As you can imagine this is not an easy or inexpensive proposition . separate transverters, antennas and amplifiers on each band! So . Im looking for four additional VX144 transverters, working or not, to add to our station. The cheaper the better. Ive already put a ton of money and resources into this project. Ive been selling off equipment that I had at the Fresno State Universitys, now defunct, HF and EME station. Fortunately I owned the majority of it. Please let me know what you have to offer. Unfortunately, my new K3 isnt due to arrive for 3-4 months (I just ordered it), but on the other hand it gives me time to acquire components and build the station. 73, Dave / W6TE DM-06 Fresno, CA (559) 323-6095 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

The reason they are not available in other data modes is because they are not applicable (AFSK and FSK D), or the fact that the center frequency allowed for the sharpest FIR filters is limited to something under 2 kHz makes them not general. 73, Lyle KK7P ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] K3 Filter prices
Jerry: I don't know if you own a K3 or not but if you don't then you should invest in one before knocking the K3 down. The fact that Sherwood Engineering and others have found the K3 to surpass the receivers in those expensive radios like the IC-7800 and the FTDX-9000, should be enough proof of the performance of the K3. I have owned many different receivers/transceivers over my ham career and I honestly have not found anything yet to be the receiver in the K3. Just my 2 cents worth from Fern with K3 #412. The high prices of the roofing filters for the K3 and optional filters for other rigs reminds me of a little history. Nevertheless, I find it especially disturbing having to pay these modern prices considering that the filters have apparently not been designed or chosen for good IMD performance or advantageous group delay characteristics. Also, some filters are reputed to have been defective. Of course, the filters may not be totally to blame for the mediocre front end performance of the K3 (compared with the professional-level performance that some of us had hoped for.)
