Re: [Elecraft] KDVR
To my understanding as its been explained before the KDVR records the audio to the memory before the processing but when you play it it is then injected into that same place in the chain and is thus sent through the processing. Therefore you can make changes to the processing settings and replay things and hear the difference. ~Brett (N7MG) (Previously KC7OTG) On Sun, Jun 6, 2010 at 10:04 AM, Merle Bone merleb...@charter.net wrote: I have a couple of questions about the DVR that I could not find answers to in the manual.

[Elecraft] K3 IO1 Error Message
When I switched on my K3 on Saturday afternoon prior to using it in Field Day it came up with IO1 error message. I will contact technical support but wondered if anyone had experienced this before. Associated symptoms are: Doesn't recognise Sub Rx, ATU or 100w PA, ie max output is 12w. It was working perfectly in the week and I am thinking a connector may have worked lose in transit. Accessing the Field Day site involved a drive along bumpy farm tracks and a steep grassy incline which my 4x4 SUV coped with OK but apparently not the K3!!

Re: [Elecraft] How to test serial communications?
Thanks, Kevin. I assume (though the referenced test procedure doesn't say it), that with pins 2 and 3 shorted to each other, each character you type on hyperterminal should be echoed on-screen twice, once locally and once by the loopback. If that's the case. then it may be that I just have a bad *computer* port, which would be good news indeed. 73, Pete N4ZR The World Contest Station Database, updated daily at www.conteststations.com The Reverse Beacon Network at http://reversebeacon.net, blog at reversebeacon.blogspot.com On 6/6/2010 4:51 PM, R.

Re: [Elecraft] K2 ATU and 43-ft Vertical
The base loading coil is nearly identical in design to the toroidal coil of AD5X, linked below. I do intend to find 160 80m tap locations for the antenna. FYI - The maximum power I've run with my 43-foot vertical and matching system is 1200 watts with no problems experienced for several months. But then one humid morning the unit did arc from the output connection across the electrical box to a nearby ground point (you could see a nice carbon trace across the box). The SWR jumped suddenly and the amplifier (ALS-1300) tripped out like it should. I replaced the output screw with a ceramic feedthru and haven't had the problem since. As Tom W8JI stated, the voltages can be extremely high especially if you are running high power. If you run an amplifier, I'd recommend using a ceramic feedthru output, and keep the output port several inches away from any ground connections.

Re: [Elecraft] How to test serial communications?
Pete, If you are using HyperTerminal (or most other terminal emulation programs), you can turn local echo on or off. When doing the kind of testing you're doing, I turn it OFF to avoid confusion. (1) In the New Connection - HyperTerminal screen, select File Properties. (2) In the New Connection Properties dialog box, click the Settings tab, then click the ASCII Setup... button. (3) In the ASCII Setup dialog box, make sure the Echo typed characters locally checkbox is UNCHECKED. (4) Click OK to commit the ASCII Setup settings. (4) Select the COM port you are going to test in the New Connection Properties dialog box and click OK to commit all settings for that port. Then the only thing that will appear on your screen as you type are the looped-back characters.

Re: [Elecraft] K3 IO1 Error Message
Chris, Random error messages on boot up still plague me frequently. Normally I get a whole series of them beginning with BP3 usually but they can vary. With me Sub always works but ATU and 100w module doesn't until I've sorted it by repeated power up cycles or just leaving on for a while and then turning off and on. One time recently it took a good hour of trying before it turned on correctly I've never been able to figure out any logic to this; no connection with temperature or the radio being moved, different firmware etc. The most recent official release dealt with 'bus timing issues causing random error messages on switch on..' but no real difference here and I'm pretty convinced it's software and not hardware or seating problems, as when I've got rid of the errors the radio works perfectly. Just when I think the problem's here to stay and decide it's time to tackle the support guys again the radio starts to behave and I don't bother but it's quite frustrating when it's in a I'm not going to start up properly mood. 73, Stewart, GW0ETF -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-IO1-Error-Message-tp5148110p5149863.html Sent from the Elecraft 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 - Help Needed in Chicago Area
Hello: I¹m in the process of assembling my K3, and I¹ve run into a problem trying to configure the reference oscillator. For some reason, I¹m unable to receive any kind of signal at all. I have a windom antenna that I plan to erect, but at the moment, I just have have it connected to the radio and then spread out in my shack over bookcases and windows, etc. I probably have about 20 25¹ spread out. Still, I¹m not receiving anything. I¹d like to ask if there is a K3 owner in the Chicago area who could either allow me to bring my radio there, connect to his antenna, and try to do the configuration or someone nearby, perhaps with a 40M dipole who could arrange to broadcast a signal at a specific time, etc. Ideally, I¹d like to bring my rig to your shack and try to configure there. I need to be able to receive WWV, and I need to be sure that my receiver is functioning properly before I install the 100Watt amplifier and the fans.

Re: [Elecraft] Would you be interested in a K2 PSK31 digital interface card?
I have a particular need which is not a digital interface per se, but need to know if this project addresses it, or if some subset addresses it. This will be used in ongoing rudimentary research on 160m antennas and ground phenomena currently under way. I will need a fixed audio output from the RX which is independent of the AF gain control, which will be fed to a meter reading in dB. We will be taking field measurements on weak signals on small antennas from low level self-contained transmitters fitted with small antennas. I saw N0SS sell off his last remaining fixed audio boards before I realized what they were. I will probably be encouraging some local friends to outfit their K2's in a similar fashion. Also, is the fixed audio board file that N0SS has in a format that can be fed to one of these small quantity PCB companies, or would it need to be converted? 73, Guy.

Pauli had a great design, and I know there are many who would like to reproduce it.. Now to relate the other half of the story -- when I was offering kits and boards for the W3FPR Fixed Audio Output, I was amazed to find that one day that Pauli ordered one. I quickly sent him an email asking why, since he had developed a great digital interface for the K2, and he replied that my solution was quite simple and elegant by comparison. Yes, the microphone and PTT switching must be done in an external interface box (many do that), but just the addition of a fixed level audio output alone is very helpful to working digital modes with the K2. If you are interested in this more simplified solution, check out either the original design on my website www.w3fpr.com or see the updated board that Tom Hammond N0SS developed which mounts easily between the Front Panel and the Control Board. Tom no longer offers either the kits nor the boards for this design, but he has offered to provide the board layout to anyone interested. See www.n0ss.net for more information. The design is not complex and can easily be implemented on perfboard if you do not want to go the route of ordering a lot of boards (and selling them to others) from FAR circuits or other board sources. 73, Don W3FPR NQ3RP wrote: I've tried to find one of EA3BLQ's interface cards for the K2 but have not been successful.

So I wondered if there was any interest out there in obtaining one of his boards. My main interest is in making the K2DI VIII board on this page http://www.qsl.net/ea3blq/k2di_pci_tec_ang.htm . If you would like one please post a reply here. If I get enough responses I'll see about doing the run. If you want the K2DI PCI card also please state that also. If I get two dozen the cost should be about $20 per board ($40 for the two). If you would like a complete kit state that also.

[Elecraft] (Elecraft K3) KDVR
Re-the current thread on using the KDVR for checking transmitted audio: When using SSB I like to monitor my audio sidetone in my phones, probably because, like most hams, I like the sound of my own voice! I recognise that this may not be a true reproduction of the outgoing signal, but it does give me an idea of the level of residual back ground noise from fans, dog barking, wife yelling at me to get and do something useful and so on. That way I can make adjustments to the mike gain and compressor gain if neccessary. The trouble is that the K3 produces a slight processing delay between my speech and the sidetone, which I find most disconcerting. I usually end up using my old TS-850 for 'phone instead of the K3 because of this.

Re: [Elecraft] (Elecraft K3) KDVR
Tom, try these steps. 1. With dog and wife away, and fans off, see how you sound, adjust as necessary. This is your baseline. 2. Dog barks, put outside 3. Wife yells, see #2. 4. After front door slams, followed by ominous silence, go outside to retreive all your belongings from the front garden. 5. Bang fist futilely on door for readmittance, and be alert to catch the rigs as they come through the window. Seriously, set it once and forget it.

Re: [Elecraft] Would you be interested in a K2 PSK31 digital interface card?
Guy - The boards as designed by EA3BLQ did not provide a line out audio signal, so using one of his boards would not provide the type audio you are seeking. While Tom's (N0SS) board does provide a fixed audio, it also requires that you make solder connections to the Control Board of your K2. If you are comfortable with doing that, then I suggest you ask Tom for his files and have a couple of boards made. Please contact Tom @ N0SS (at) arrl.net for any more discussion about your needs.

There is a modification to improve the supply rail decoupling on the bus which would appear to have cured my K3's ills in that department. Send a mail to Elecraft support. 73 Stewart G3RXQ On Mon, 7 Jun 2010 09:32:52 -0700 (PDT), GW0ETF wrote: Chris, Random error messages on boot up still plague me frequently.

One time recently it took a good hour of trying before it turned on correctly I've never been able to figure out any logic to this; no connection with temperature or the radio being moved, different firmware etc. The most recent official release dealt with 'bus timing issues causing random error messages on switch on..' but no real difference here and I'm pretty convinced it's software and not hardware or seating problems, as when I've got rid of the errors the radio works perfectly. Just when I think the problem's here to stay and decide it's time to tackle the support guys again the radio starts to behave and I don't bother but it's quite frustrating when it's in a I'm not going to start up properly mood. 73, Stewart, GW0ETF __ 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] Would you be interested in a K2 PSK31 digital interface card?
The boards as designed by EA3BLQ did not provide a line out audio signal, That is not correct. The EA3BLQ Digital Interface board (K2DI v. 3) provides a buffered/amplified signal from J5 (demodulator output before the volume control). This is the definition of a line out signal. While not quite the same as Tom's board (Don's design), the EA3BLQ K2DI board is functionally identical on receive and provides for PTT microphone switching/muting that is missing in Don's design. The K2DI board can be used on a stand alone basis if one does not need the digital mode VOX (e.g. tone switching) or transformer input/output isolation provided in the K2DI-PCI daughter board. 73, ...

Re: [Elecraft] Part across ant output on KPA100
Glenn, You are reading from the newer KPA100 manual and you have an older KPA100 on your hands. That would be RFC10, and will be found in KPA100s without the more recent T/R switch upgrade KPA100UPKIT. If you look closer, you will find toroids at L15 and L16 wound on red toroid cores, and a similarly marked RF Choke at RFC1. That T/R switch design change was to combat a potential parasitic oscillation just above the 40 meter ham band. I would suggest that you install the KPA100UPKIT on that KPA100 while you are working on it. If it does not have the upgraded shield - with the spring clips, speaker shield, narrow opening above the SO-239 jack with 2 soldering lugs that connect the shield directly to the SO-239 jack, you should also install the KPA100SHLDKIT (or something like that designation). 73, Don W3FPR Glenn Biggerstaff wrote: Hi ,I am repairing a KPA100 that suffered some lightning damage .I have fixed most of it ,but have a question .The alignment and Installation (page 44 in the manual ) calls for 10 k from the center pin of the ant connector (J2) and ground. I have that but only with a part that seems to be added from the center pin to ground removed .It is marked 5800 101 and I think it is a inductor. It measures a couple of tens of an ohm dc and seems to be about 880 uh .Is it supposed to be there ?I don't see it on the schematic .
