What is all this Droid stuff? I am afraid the latest shipping date estimate of 16th December is just too late for all of us in the UK. The tax applies when it arrives, not when it was sent. So that is only 2.5% but the Dollar is going up again as well. I am wondering about cancelling. I have been thinking about it for a while. As far as I can tell there are no advantages over the XV144 at this time. The milliwatt output for driving microwave transverters is not in place yet.

Re: [Elecraft] AF/RF Knob situation - joined the club Me Too!
Don Ehrlich wrote: ...Not so, and obviously not a problem of a single batch of knobs... I think there has been some misunderstanding here. My reading of Eric's explanation is that the KNOB MANUFACTURER screwed up in a single batch (or perhaps a few consecutive batches) of knobs. Typically, with parts made in batches, all the batches go into the same bin after initial inspection to make sure they meet specs, and are subsequently shipped out from the mixed bin, irrespective of the original manufacturing batch they came from. This would mean that, out of a given lot shipped to the customer (Elecraft), a few of the knobs in each shipped lot will likely be from the bad manufacturing batch until ALL knobs from the bad manufacturing batch(es) have been used up (or the problem is discovered and all existing knobs are purged). This could potentially take a LONG time, and explains why some end users have in the past received two different shipments from Elecraft of knobs that turned out to be bad. According to Eric, the problem was discovered months ago and there are no more bad knobs in Elecraft stock, only newly-manufactured knobs with the fiberglass fill.

[Elecraft] K3 fails low power cal
I've sent this to Elecraft tech but thought I'd post it here too. My K3, using latest firmware, fails the low power cal on 160. On all bands the power out doesn't vary with the power knob until the K3 kicks over to the 100W amp then acts correctly. I've tried, several times, the power cal using the K3 utility but fails each time.

[Elecraft] K3 PSK31 split freq?

Hi All, Just checked some of the knobs and it would seem some of the threads in the knobs are not parallel and get tighter as the grub screw is screwed further in. It would seem that a tapered tap has been used on some of the holes and due to small shaft hole has not been through enough to make a parallel thread. 73 Tim gm4lmh __ 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] K3 Distorted Sound while using AM
If you're using the 2.8 or 2.1 filters for AM mode reception, it would probably sound distorted. The 2.8 works fine for listening to AM in SSB mode though. matt W6NIA K3 #24 On Sat, 05 Dec 2009 21:50:28 -0800 (PST), you wrote: Hey Joe, Thanks for the fast reply! No, I do not have the AGC Off, nor have I changed any of the settings within the AGC (Menus). I should have stated that in my original post. Anyway, I am really stumped as what the problem is. If you happen to have a K3 equipped as mine, could try to listen to an AM station with the Volume turned up, to see if you are receiving the distortion? I should have been more specific, the radio is totally loaded. It does have the 8 Pole filters in both receivers. From my recollection I have the following filters: 250 Data CW, 2.1 for SSB, 2.8 for SSB, and 6 for AM, and 13 for FM. I hope this makes it a litter clearer and not more confusing. Thanks Joe, Rick Thanks, Rick Joe Planisky wrote: Hi Rick, Do you perhaps have AGC turned off and the AF LIM set to a value of less than 30? The distortion and eventual cutting out of audio at high levels you are describing sounds a lot like the intended AF limiter action. If so, the solution is to either turn on AGC, or increase the AF LIM setting closer to 30. I find an AF LIM setting of 28 allows as much dynamic range as I want while still protecting my tender ears from various pops and static crashes. The AF limiter is intended to protect your ears and speakers from unexpectedly loud signals when AGC is turned off. It will prevent the output from exceeding the preset value at the expense of distortion. 73 -- Joe KB8AP On Dec 5, 2009, at 8:50 PM, Richard Jones - KJ5QY wrote: Hello, I am having a problem when I go into AM, or AM sync.

Re: [Elecraft] K3 Distorted Sound while using AM
My audio will distort and cut out as you describe if it's a very strong AM signal (nearly full scale on the s-meter) and the volume is turned up to that extreme. But that is really loud. I usually have the AF Gain set at 1/4 rotation or less, so don't really consider it a problem here. I never under any circumstance have to go up as far as 3/4 on the AF Gain (unless the AGC is off and the RF Gain is way down, in which case there is no distortion). FWIW, you can set Config: AF GAIN to HI or LO. The feel of my AF RF controls are smooth. They have a very small side-to-side play but no bad wobble/looseness as you describe. When I rotate the RF Gain full CCW it is very quiet, just a very faint noise level can be heard with the AF Gain full CW. I consider it normal operation. 73, Drew AF2Z On Sat, 05 Dec 2009 20:50:25 -0800 (PST), you wrote: Hello, I am having a problem when I go into AM, or AM sync.

Re: [Elecraft] K3 and Firewire
Top posting feels all wrong ;-) Forget Firewire for this. Firewire is admittedly very good but it's far from standard on non-apple products and USB3 is going to give it a good run for it's money in all areas except perhaps Pro A/V where latency is a huge concern. However the real issue with both firewire and USB is the need it then creates for the Vendor (elecraft in this case) to maintain drivers for various versions of popular operating systems for the life of the product ( what happens to those drivers when the product becomes EOL) . I have an SDR-14 and I can transfer up to a 190KHz slice of the HF spectrum via USBv1. How much bandwidth is really required ? (Main RX / Sub RX + I/Q of the 12KHz IF + Rig control ? ) A much better solution would be Ethernet and IP based protocols. it's also a lot more flexible in that the connection to the radio can be routed over any network providing sufficient bandwidth is available. This also avoids the need to maintain a set of high quality drivers for a diverse and ever changing range of operating systems. 100M Ethernet should be sufficient but by all means use a Gigbit port, it will only add a small amount to the overall cost. Use a little tiny embedded computer to run the IP stack and there could even be a web server in there allowing for remote rig control, Audio I/O etc without needing to use anything fancier than a Flash capable web browser. Embedded computers are getting very small and very capable, take a look at this one for example . http://www.directinsight.co.uk/products/karo/triton-tx51-imx51.html 73 Brendan EI6IZ On Sat, 2009-12-05 at 21:59 -0500, p...@n4lcd.com wrote: Just thinking out loud into the future Firewire can do a lot of things that USB and serial communications never will. It's faster with video and disk I/O because the protocol is leaner, and you can create networks with it. I think that a FireWire network between a rig like the K3 and a computer would be the perfect interface because every piece of software can have its own dedicated connection to the radio, something difficult to implement with a serial connection. Firewire will also stay around because it's used as the Fly-by-wire bus for the F-22 Raptor. Any thoughts?

[Elecraft] Filter talk and contests etc
With all the filter discussions and contest crowded environment etc. This AM during the 160 contest, I was just tuning and working a few to give out a point, as I tuned across 1814.0 there was a 10 over 9 6 land station calling cq, and at 1814.35 another 6 land at 20 over 9 calling cq, but between I hear a signal at 1814.2 so narrowing down the K3 I proceeded to work VQ9LA who was just above the noise level. Have done this many times since owning the K3 and its a real tribute to its selectivity and ability to cope with signals loud enough to squash most receiver front ends. Im sure it does not make for friends when you come on within a few hundred cycles and work stations out from under the big signals, but sure makes for nice DXing on topband. 73 Merv KH7C __ 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] [K3] K3 and Firewire
Hi, I agree with you, Brendan, Ethernet is the way to go. Ethernet is always transformer coupled so there are no problems with ground loops and that also helps with noise, although the unshielded Ethernet cables don't help in this regard. More and more microcontrollers, especially ARM based ones, now come with fast Ethernet controllers onboard and IP stacks are easy to come by these days. So a separate embedded computer to run the Ethernet interface is often no longer necessary. Knut -AB2TC Brendan Minish wrote: Top posting feels all wrong ;-) Forget Firewire for this. Firewire is admittedly very good but it's far from standard on non-apple products and USB3 is going to give it a good run for it's money in all areas except perhaps Pro A/V where latency is a huge concern. However the real issue with both firewire and USB is the need it then creates for the Vendor (elecraft in this case) to maintain drivers for snip -- View this message in context: http://n2.nabble.com/K3-and-Firewire-tp4120102p4121993.html Sent from the [K3] mailing list archive at Nabble.com. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
[Elecraft] [K3] KRX3 install question?
I'm installing a KRX3 in K3 #2006 and have a small confusion. I'm on p. 20 of the KRX3 installation manual. I have confirmed that R91 has a value of about 22 ohms (21.9 on my meter). The 4th step on the page says that if that is the case, skip directly to the next page. Being curious, I looked at the next step on p. 20 which talks about cutting some traces if they have not already been cut. On my board, these traces are NOT cut. But it looks like I have been directed to skip this step. So should I cut the traces or not??? 73, Randy, KS4L __ 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] AF/RF Knob situation - joined the club
Hi Julian, I am just reading your emails now as I eat my Sunday morning breakfast. (Hopefully my wife won't notice I'm reading email at the breakfast table..) I was not able to read or respond to list postings most of yesterday (Saturday). Our Elecraft company holiday party was last night and I was busy with preparation for that and welcoming our out of town employees as they arrived, giving them a tour of our new headquarters. (Gary Surrency, Lyle Johnson and a number of others.) I think you may have misunderstood my earlier posting to the list regarding the concentric AF/RF K3 knobs. I definitely was -not- saying that the only serial number range where concentric AF/RF knobs could crack was from the problem plastic batch earlier this year. That was just the trigger point that prompted us to change the plastic formulation. Its quite clear that some concentric knobs from earlier K3s have been broken. In many cases over-tightening of the set screws could cause breakage of knobs on earlier K3s. Most of the failures reported to us fell in that category, but there certainly could have been other failures. The number of knobs failing inside the problematic plastic s/n range though were an order of magnitude higher than those outside that range. The jump in knob failures earlier this year is what alerted us that there might be a manufacturing / supplier issue. That's why, when we encountered the problem batch from the manufacturer earlier this year, we decided to go further than just requiring them to replace the bad ones with proper equivalents. As noted in my earlier list posting, we also changed the plastic formulation to add glass fiber to the mix, which makes the current knobs extremely rugged. We tested them by over tightening the set screws to an extreme, way more than is easily done by hand with the supplied Allen wrenches.. The set screws on the new formulation knobs always gave out first. :-) We couldn't break them short of hitting them with as hammer. These knobs are custom manufactured for us by EHC, a highly respected custom knob manufacturerr. That's why we were caught off-guard when they ended up having problems. I also noted in my earlier posting that we will replace for -free- under warranty, indefinitely, all concentric K3 knobs that have problems. That applies to -any- s/n K3, not just the ones in the problem batch. When any customer contacts pa...@elecraft.com and reports a breakage of any of these knobs, we will send out a complete set of four new concentric knobs, no questions asked. If you are nervous about your concentric knobs, please feel free to email pa...@elecraft.com and we will send you a new set gratis. And of course, -all- new K3s have been shipping with the improved plastic formulation concentric knobs for a number of months. When I get to the office tomorrow, I'll post the approximate date and s/n range to the list and our K3 mods/alert page so there is no confusion. 73, Eric WA6HHQ Julian Moss wrote: Hi Don. I'm replying direct and copying this to Dave G4AON and to Eric because I sense that some members of the list are tired of this issue but I want Elecraft to see it. Your explanation does not make sense to me. Al WA6VNN's K3 has serial number 31. Dave G4AON's serial number I think is 80. Don K7FJ has now posted to say the problem is apparent with his K3 serial number 195. All those radios were made at the end of 2007. How do they come to have knobs from a faulty batch which was manufactured during early 2009 if I understood Wayne or Eric's original explanation of the issue correctly? I don't see a problem yet with my own K3 serial number 222 but that may be because it hasn't been as heavily used as some of the others. But I am afraid that if I needed to remove and replace a knob for any reason that might be enough to cause a fracture. In short, I no longer have confidence that the knobs on my K3 will not fail. I'd rather fix the problem now than wait for a failure to happen and then send for a replacement at a time when it may not be so easy or convenient. But rather than lie about having a broken knob to get a replacement as some people have suggested I'd rather be able to obtain new ones officially. 73, On 06/12/2009, Don Wilhelm w3...@embarqmail.com wrote: Julian, Not all older K3s are experiencing the knob problems. I have one of the early K3s along with the others in the K3 Firmware Field Test group, and there have been no identified problems with the knobs used at that time in my recollection. This is the result of a batch of faulty knobs, just as Eric has described, and while it will take a while for all of the faulty knobs to be identified, it is just a batch problem - IMHO, there is no need for Elecraft to arbitrarily supply knobs to those K3 owners that do not have a problem. It may take a bit of time for failures to show up, but the fix is available at no cost

Re: [Elecraft] [K3] Does anyone have an answer to this? Re: M1-M4: Can the CW Paddle that has four memory switches, be wired directly to the K3? Switches built into paddle base.
Mark, Well, on the basis of anything is possible, I guess one could add extension wires to the PC board where the M1-M4 buttons make contact. But I don't believe anyone would really want to do that. There are no direct access signal lines to the pushbuttons. However, any pushbutton is accessible through the RS-232 interface, so if you can devise something (dedicated controller or PIC) that would take input from those switches and massage it into the proper syntax to put into the RS-232 port, then your pushbuttons can be used. I am not certain why you are opposed to an external keyer, some keyer chips with memories are quite small and might be contained directly on your paddle base or adjacent to it. I am thinking of some of the keyer kits offered by K1EL - check out http://k1el.tripod.com/K12.html for info on the K12 keyer, it is quite small. 73, Don W3FPR Mark M W2OR wrote: Shall we assume the answer is no to the below question ??

Re: [Elecraft] [K3] Does anyone have an answer to this? Re: M1-M4: Can the CW Paddle that has four memory switches, be wired directly to the K3? Switches built into paddle base.
I suspect no one has responded because people are not sure and don't want to lead you down the wrong path, Mark. You need to make the circuit closures at your key that the M1 through M4 buttons do on the front panel. To do that with simple switches would involve paralleling those button contacts with connections to the switches at your key. First you'd have to dig into the front panel to make the connections and then there's a whole spectrum of problems that might occur with wires connected to those circuits. Noise radiation into the receiver, RF pickup that would activate those functions spontaneously, or activate some other Front Panel board unexpectedly when you transmit are just a few that come to mind. Bottom line, it appears to require some serious technical evaluation and testing of the installation. The better approach would be to command those functions via the rear panel RS232 interface, but that requires a lot more than a switch at your key. It might be done with a black box interface unit to produce the right data outputs in response to a switch closure at your key, but again that also requires a significant design effort.

Hmm... 12V at 500 mA is only 6 watts-- perhaps the 14 watts refers to the power drawn by the wall wart while supplying rated current. If that's the case, then I wouldn't use it for the K3 (mine with one Rx and no antenna tuner draws one amp. at 14V.) My K2 QRP version with most accessories, including DSP, draws about 300 mA, so the wall wart might power your K2. 73, Chuck NI0C __ 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] OT: wall wart for RX-only PS?
Hello Doug, Most of the wall warts are just rectified AC. Very little if any filtering. I would not advise it unless you put it across a battery, however, I would be more comfortable getting a surplus laptop switching power supply and adjust the voltage down to 13.5 VDC or so. Most of the laptop supplies are about 15 VDC and VERY good on filtering and capacity. I used two silicon diodes in series to drop the voltage to run my 817 on both RX and TX. It was the size of a double deck of cards. I got mine for $15. Good luck.

Re: [Elecraft] [HAM] Windows 7 and LoTW
Dan, I have Windows 7 Home Premium 32-bit. It is an upgraded system from Vista. I just uploaded my latest contacts to LOTW without any problem. This is the first time I've tried it with Windows 7. I use DX4WIN for my log. I used a filter in DX4WIN to select only the latest entries. I then created an ADIF file and was then able to create a tq8 file without any problem. LOTW accepted it. I haven't touched any LOTW stuff on my computer since the upgrade to Windows 7. About a year ago I had trouble creating a tq8 file. Come to find out my certificate had expired. The error messages I was seeing didn't give any indication that the problem was with an expired certificate. It's been long enough that I forget just what the messages said. I'm not sure what is wrong for you, but I can say that LOTW seems to work fine on my Windows 7 computer. Roger, W1EM The error appears to be related to the way tQSL writes to its own data files. I have checked all the permission issues and tried running it as the Admin and even as an XP SP3 program. No luck. I hope to find someone who has found the secret formula. This is in Win 7 Professional. The tQSL program and the LoTW setup has never been my favorite.

No, I do not have the AGC Off, nor have I changed any of the settings within the AGC (Menus). I should have stated that in my original post. Anyway, I am really stumped as what the problem is. If you happen to have a K3 equipped as mine, could try to listen to an AM station with the Volume turned up, to see if you are receiving the distortion? I should have been more specific, the radio is totally loaded. It does have the 8 Pole filters in both receivers. From my recollection I have the following filters: 250 Data CW, 2.1 for SSB, 2.8 for SSB, and 6 for AM, and 13 for FM. I hope this makes it a litter clearer and not more confusing.

The distortion and eventual cutting out of audio at high levels you are describing sounds a lot like the intended AF limiter action. If so, the solution is to either turn on AGC, or increase the AF LIM setting closer to 30. I find an AF LIM setting of 28 allows as much dynamic range as I want while still protecting my tender ears from various pops and static crashes. The AF limiter is intended to protect your ears and speakers from unexpectedly loud signals when AGC is turned off. It will prevent the output from exceeding the preset value at the expense of distortion. 73 -- Joe KB8AP On Dec 5, 2009, at 8:50 PM, Richard Jones - KJ5QY wrote: Hello, I am having a problem when I go into AM, or AM sync.

We have a lot of power interruptions up here in the Santa Cruz mountains, thanks to storms, falling trees, and wild fires. Rather than buy a lot of commercial units, I have put together a bunch of little home-brew back-up power supplies for most of this gear. I simply find suitable batteries at swap-meets and use a wall wart as a float charger, with a parallel feed to the equipment. To avoid overcharging the battery, I carefully match the normal charging current so that current into the battery falls into the trickle range (5% -10% of the 10 hour discharge rate). This tends to work quite well. When power drops, our internet router, AC powered phones, Ethernet switch, etc. all continue to work just fine, even through relatively long outages. Likewise, my 12-14v ham gear runs on a couple of big Costco deep cycle batteries that are charged from a little 10A supply. Again, charging current is kept below that which could degrade the batteries.

Re: [Elecraft] CAT
Jim, See the K2 Programmer's Reference for all the commands that can be sent/received via the K2 through the KIO2 interface. Keying uses the KY command, and in SSB or RTTY mode, the TX command will set the transmit state (pulls PTT low). If your software application can issue those commands, then it is possible - if the commands are not available, all you can do is appeal to the applications author to include that support - I don't know those specid\fics of MixW. Please resist the temptation to refer to the K2 AUX I/O as an RS-232 port - it is NOT, even though it contains TXD, RXD and Signal Ground as RS-232 signaling levels. Other pins are used for internal K2 signals that are used by other Elecraft devices such as the KAT100 and the KRC2. Connecting a standard computer serial cable to this AUX I/O connector can damage your K2. Just because it uses a DE-9 connector does not make it a serial port (that should true for any device using a similar connector - if it is not marked as an RS-232 connector, it probably is not, check the manual for the device first). 73, Don W3FPR Jim Dunstan wrote: Hi Is it possible to send a PTT and,or the CW keying commands to the K2 via the RS232 port if the K2 has the KIO2 module installed . using software such as MixW. __ 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

Hit the Xmit again and it came back alive. Did not have that issue again. I wonder what that was? The other issue is that I hit a key on N1MM and the K3 jumped in frequency and the RIT was way off.

Re: [Elecraft] [K3] K3 Distorted Sound while using AM
I think I found at least one of the problems. If you go into the RX EQ (by clicking the MENU button, then turning the knob until you see the RX EQ 1). Next, turn the lowest base control (Number 1) up from the 0 EQ position until you here the distortion on AM. It will not take much. On my rig, just taking it a few levels (Db) above the reference the distortion on AM is there in a vengeance. The following is the most important as I have found: If you have/get the distortion and you raise the Shift Control (While in AM or AM Sync) from *150 to 155, the distortion completely goes away!!! I am not sure what is going on here. I hope this, and the posts above will give some additional information on what I am experiencing, and hopefully an answer.

The AF knob feels like it was one of those old potentiometers that we are all aware of (Get scratchy after use and loose). From my understanding Elecraft used extremely fine pots with a very long life (They do have a bad wobble/looseness in them though). Upon further investigation I found that if I rotated the RF gain control from the fully clockwise position (all the way open) to the full counter clockwise position (all the way closed) that when you almost get to the end of travel the radio audio goes completely dead. I have tried this multiples times and it is very repeatable. After more investigation I found that if I rotated the shift (While in AM or Sync AM) control from its standard (Normal) value of 1.50 to 1.55 this horrible distortion would disappear? I am really confused as to what is going on here. This happens while in the Normal AM mode as well as the Sync AM mode. I have tried to explain this in away that I hope most people will understand my problem (I am not an EE). Could others please let me know if it is my unit or a wider problem?

Some sort of DC blocking between DSP and DAC could help. (also for the PB shift clicking effects) 73' Paul PD0PSB Richard Jones - KJ5QY wrote: I think I found at least one of the problems. If you go into the RX EQ (by clicking the MENU button, then turning the knob until you see the RX EQ 1). Next, turn the lowest base control (Number 1) up from the 0 EQ position until you here the distortion on AM. It will not take much. On my rig, just taking it a few levels (Db) above the reference the distortion on AM is there in a vengeance. The following is the most important as I have found: If you have/get the distortion and you raise the Shift Control (While in AM or AM Sync) from *150 to 155, the distortion completely goes away!!! I am not sure what is going on here. I hope this, and the posts above will give some additional information on what I am experiencing, and hopefully an answer. Thanks, Rick Richard Jones - KJ5QY wrote: Hello, I am having a problem when I go into AM, or AM sync. Example: I go to an AM Shortwave station. If I turn the AF gain past approximately 3/4 or farther the radio starts to Stutter, Distort, and finally the audio disappears. I cannot make out what is coming out from my speaker. The audio is completely distorted or gone. I noticed I could rotate the Af gain (Counter Clockwise) and it would go back to less distortion. I did check the external speaker jack and also unplugged it only to find the same problem. The AF knob feels like it was one of those old potentiometers that we are all aware of (Get scratchy after use and loose). From my understanding Elecraft used extremely fine pots with a very long life (They do have a bad wobble/looseness in them though). Upon further investigation I found that if I rotated the RF gain control from the fully clockwise position (all the way open) to the full counter clockwise position (all the way closed) that when you almost get to the end of travel the radio audio goes completely dead. I have tried this multiples times and it is very repeatable. After more investigation I found that if I rotated the shift (While in AM or Sync AM) control from its standard (Normal) value of 1.50 to 1.55 this horrible distortion would disappear? I am really confused as to what is going on here. This happens while in the Normal AM mode as well as the Sync AM mode. I have tried to explain this in away that I hope most people will understand my problem (I am not an EE). Could others please let me know if it is my unit or a wider problem? I am using 3.59 and the serial number is 283?. This unit was fully loaded and built by Elecraft.
