Re: [Elecraft] K3 External ALC Mod
Roy, Yes, they are relatively critical. Only one minor point - they do not "produce" - 4 volts of ALC, instead, they allow an ALC voltage of up to -4 volts (from the amplifier) to be translated to the positive ALC voltage required by the internal circuits in the K3. If you skip to the photo on page 4, the location of the cut and the end of the 137k resistor may be more apparent to you because the annotations are not present. 73, Don W3FPR Roy Morris wrote: > The mod revision sheet of the digital IO board shows the 69.8K > soldered to pin #1, and the 100K soldered to pin #20.

[Elecraft] K3 External ALC Mod
The mod revision sheet of the digital IO board shows the 69.8K soldered to pin #1, and the 100K soldered to pin #20. The remaining leads of these two resistors appear to be soldered to pin #9 along with one end of the 137K. The other end of the 137K goes to who knows where. The cut trace does not show clearly what trace is to be cut and where the 137K terminates. It is also unclear if the 69.8K, 100K and the 137K resistors are just soldered to each other or are terminated to Pin #9. Why is it necessary to use 1% resistors? Are these values critical to produce -4 volts of ALC?

Re: [Elecraft] K2, kio2,kat100

Re: [Elecraft] Crystal filter locations on main and sub receivers?
Either will work just fine. Your choice. Just configure the radio to match where the filters are physically plugged. The 13 kHz FM filter MUST be in Main FL 1 if you wish to transmit FM.

Re: [Elecraft] K2, kio2,kat100
Brett - The KPA-100 and KAT-100 must be powered up before the K2, or at least at the same time, or the "high power" indicator on the KAT-100 will not come on, and also (I think) the actual changeover to put the amplifier "on line" will not occur. An artifact of the way the KIO2 works, I think. However, if you don't actually have the amplifier installed, I suspect that the symptoms you see are normal. - Jim, KL7CC Brett Gazdzinski wrote: > One thing I notice though, when I adjust the power of the k2 past 10 watts, > the kat100 tuner does not change to hi power. > Does it only do that if I have the kpa100? > > __ 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

The number reported following "TX EQ" or "RX EQ" is the frequency band that is being equalized, not the setting of the equalizer. To demonstrate that the EQ *settings* are in fact saved, insert these steps: 1a) rotate VFO A to clockwise so VFO B's display reads " 0.80 +2". The fifth location in VFO A will be two parallel horizontal lines " = " showing that the 800 Hz frequency range has been boosted slightly. 4a) Note that the fifth location in VFO A is still two parallel horizontal lines " = " showing that the 800 Hz frequency range has been boosted slightly. Thus, the adjustments made before cycling power are saved through power cycles. --- What has *not* been saved is the fact that the last frequency band you were *adjusting* was band 5. Thus "TX EQ 1" is displayed, showing that any adjustment you make will be to frequency band 1 (50 Hz). Simply tap keypad 5 to go back to adjusting the 800 Hz frequency band. Finally, while in TX EQ adjust mode, press the CLR button near the RIT knob to restore the default (flat) EQ settings. 73, Lyle KK7P __ 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 TX EQ Not saving on power down
Jerry, The EQ frequency bin to change is not saved. Only the *changes* to selected EQ bins is changed. Once you've tapped '5', for example, you're in that bin, but you then have to move VFO A to adjust the gain for that bin. This will be saved. 73, Wayne N6KR On Feb 12, 2009, at 2:11 PM, k4...@juno.com wrote: > Hi K3ers: > > The below is the procedure I use to activate TX EQ. TX EQ does not > save when powered off.

Re: [Elecraft] Proset Plus HC-4/HC-5
Yes, the Heil Proset Plus with HC-4/HC5 elements can be used with the K3. Yes, the Kenwood adapter is the correct one if you prefer front-panel connection of your microphone to the K3. The Heil adapter is an AD-1 K. It's red, and has an 8-pin Foster plug. Alternatively, you plug the 1/8" microphone connector from the Heil headset directly into the K3 back panel mic connector, making an adapter unnecessary. However the back panel phone jack is a 1/8" stereo connector, which makes plugging a 1/4" stereo plug a bit unwieldy. Flexible "pigtail" adapters exist, but they're clumsy and rigid adapters 1/4" to 1/8" adapters may stress the 1/8" jack excessively. I ended up with a Heil headset that came with a 1/8" stereo plug for the headphones with an adapter for 1/4" when I need the larger size. 73 de Dick, K6KR -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Terry Sent: Thursday, February 12, 2009 12:56 PM To: Elecraft@mailman.qth.net Subject: [Elecraft] Proset Plus HC-4/HC-5 I apologize if this has been covered but I couldn't find anything in the archives.

Re: [Elecraft] K2-XV222 RFI Susceptibility Problems - a solution found
That filter has pretty much the same attenuation at 50 MHz as my homebrew one, so yes, it should work fine. Mine has better match at 28 MHz, at the expense of not as good match at lower frequencies. I ended up with the following, after some tweaking My filter is a two section low-pass pi-network. The two inductors are both 7 turns #22 AWG enamelled wire on T30-6 cores. The capacitors to ground at the input and output are both 166 pf (91 pF and 75 pF dipped silver-mica caps in parallel). The capacitor to ground at the junction of the two coils is 309 pF (270 pF and 39 pf dipped silver-mica caps in parallel). Measured > 30 dB return loss and < 0.5 dB insertion loss over 27-30 MHz (mind you my measurement setup probably isn't really accurate enough to reliably measure 30 dB return losses). Also > 30 dB attenuation at 50 MHz. When I try modelling the filter with SPICE I get only a fair agreement with measurements. I think the lead length and other strays are not insignificant. So if anyone else builds one, be prepared for some tweaking if you want best performance. The K2/K60XV now (after tweaking) likes the impedance it's seeing and can provide full 1 mW output with the filter mounted right at the output of the K60XV and a few feet of 50 ohm cable to the transverter. 73, Steve VE3SMA --- On Thu, 2/12/09, wayne burdick wrote: > Minicircuits makes a 30 MHz in-line (BNC) low-pass filter > that should do just as well, for those who don't want to > roll their own: their model #BLP-30+.

Re: [Elecraft] K3 aux receive antenna input
Such small loops have worked very well. However, they are becoming more and more difficult to use indoors than ever before. Some of the most difficult QRN/QRM sources are right in our homes and their number increases every year. (I'm typing this message on one of the most prolific QRN sources today, but your refrigerator, washing machine, furnace and even many lights are just a few examples of others we have in our homes.) While a loop can be oriented so as to put a source of interference in a null (assuming the desired signal is not in the same direction), all too often our homes have multiple sources of QRN or the QRN is being propagated along the house wiring so it is, indeed, coming from all directions at once if the antenna is inside or near the house. Before investing a significant amount of money in any indoor antenna, it might be worthwhile to string up a simple loop on, say, a wall, using a few push-pins. For a smaller test antenna, wrap a number of turns of hook up wire around a large cardboard square or circle. You can tape it in place near the periphery of a disk cut from a box. Hook one lead to the center pin of the antenna connector and the other to the chassis. It's not necessary to resonate the loop, but you can if you have a variable cap about. Put it across in series with the loop and adjust the turns to get a peak across the most interesting frequencies. Resonance provides some gain but gain is not an issue with a decent receiver. You can hear all that you'll ever hear as long as the QRN level rises when you connect the antenna to the rig. Compare that to even a modest outdoor antenna and see if you like the results. If not, you'll not likely be happy with the performance of a more expensive indoor antenna. And if you do like the results from the indoor antenna, you may find no significant advantage to using the expensive one, Hi! So why would anyone buy such a loop? Lots of reasons - here's a few: 1) They cannot put up any sort of outdoor antenna. A poor antenna is always superior to no antenna at all. 2) They live in a frame or other non-metallic building with few or no electrical devices inside. 3) They *must* have a tiny, compact antenna to fit in their space or provide the portability required. 4) It looks "right". (Don't laugh. A lot of expensive stuff is purchased because it "looks right" regardless of performance - or lack thereof: everything from homes, cars, boats and aircraft to Ham rigs.)

A bit? $380 plus tax and shipping is a lot to pay for a box that replaces something you can build for a few dollars! Unless you're hoping the loop will reject RX noise, a hunk of wire works fine with a K3! And a loop will reject ONE noise source at a time. Your money would be far better spent on a copy (even an older one) of the ARRL Antenna Book, which includes several receive loops you can build.

Re: [Elecraft] K3 external qro keying line
The K3's T-R line output ("KEY OUT") can switch up to 200VDC @ 5A... so it will
easily switch the +120VDC @ 15-30mA from the SB-220.
However, it will NOT SWITCH a NEGATIVE T-R line voltage UNDER ANY
CIRCUMSTANCES!
Users with amps which offer a negative T-R line control voltage will have to
provide alternate switching (relay, or solid state).

Re: [Elecraft] K3 configuration finalization plus diversity receive antenna question
Okay. You plan to use it on the HF bands and not the FM broadcast band. I guess I jumped to an unwarranted conclusion about that. I'm sure you will enjoy your new radio very much. I hope to hear you on the air in their future.

The other FM filter on the main will only be used for 10m FM TX/RX. Here's an excerpt from a conversation I had with another fellow regarding the use of FM filters for AM broadcast reception: > Just to make sure I understand you, the AM filter is only required if > one desires to transmit in AM or use ESSB. > Otherwise, AM reception like SW can still be piped through the 13KHz > FM filter? Correct, I use the FM filter for listening to AM broadcast or SWL on a fairly regular basis. > How does the audio of AM SW sound going through the FM filter? > Bandwidth is obviously wider, so I'm assuming higher fidelity? Somewhat higher fidelity. The K3's DSP has a fairly sharp cutoff at 4200 Hz so you will never get more than that but the FM filter allows the full 4.5 KHz where the AM filter starts to roll off at 3 KHz but still has some audio response down the filter skirts. I hope that someday Elecraft will "open up" the audio in AM so we can hear 5.5 or 6 KHz which as good as it gets these days. Hope that helps to clarify. 73, James KC2UEE _ From: Bruce McLaughlin [mailto:bmcla...@bex.net] Sent: Wednesday, February 11, 2009 8:27 PM To: 'James Sarte' Subject: RE: [Elecraft] K3 configuration finalization plus diversity receive antenna question That sounds like a well-rounded package, although, I'm a bit confused by your plan to use the FM filter on the sub receiver for broadcast reception. The K-3 will not go to the FM broadcast band and I don't think you can get there using a transverter either. Also, the 13 kHz roofing filter, and the DSP are not really wide enough for broadcast FM. The 15 kHz deviation is such that I think you will have considerable distortion on a system designed for a maximum of 5 kHz deviation if it is recognizable at all. I could be mistaken about that, but you may want to check with others. I also wonder if you could save a bit of money by having only one 13 kHz filter installed on the main receiver. Assuming it will work for FM broadcast reception, unless you plan to listen to FM broadcasts for long periods of time, I would think using the main receiver for that purpose would probably be sufficient. It also could be used for FM transmission on the ham bands. As I am sure you know, you cannot transmit using the sub receiver. I have 2 K3s. The older unit has an FM filter installed in the main receiver. The newest unit has no FM receiver filter since my use of FM is likely to be very limited and certainly not at all until 10 meters begins to work again. But your plans may be different and you may have different needs.

[Elecraft] K3 Accessibility aids
I'm currently working on three different initiatives to aid access to K3 capabilities for all of us: 1) K3 Voice, an update to K2 Voice. This is a Windows program that provides on-demand aural feedback (with Eric Swartz's voice) of K3 control settings and, optionally, automatic aural feedback when controls are changed. A prototype of K3 Voice was shown at the Consumer Electronics Show in Las Vegas. The K3 has a substantial number of controls and configuration settings, and we're currently expanding from K2 Voice capabilities to the K3 "normal operation" set of controls toward configuration control. The task is huge and will evolve over time. 2) I'm working to improve the K3's Utility's accessibility so that it can be used with a screen reader and no mouse. I have two blind K3 owners that are evaluating tentative changes and are not shy about making recommendations. They were particularly critical of the Crystal Filter configuration page which is almost impossible to use without a mouse. 3) A CW memory editor (a dialog with within the K3 Utility) that helps CW enthusiasts who have difficulty manipulating a paddle to set the K3's internal CW memories using a computer keyboard. Frankly I'll use this one myself... Expect to see some of these features later this month. 73 de Dick, K6KR -Original Message- From: "David Ferrington, M0XDF" Date: Thursday, Feb 12, 2009 12:02 am Subject: [Elecraft] Specific button feedback (was: terminal window in k3 utility) To: wayne burdick CC: elecraft@mailman.qth.net Perhaps it's time for us sighted ops wanting firmware features and additions etc. to take a step back and give Elecraft some time to introduce some form of feedback for our fellow ops with vision problems. I have no idea what would work best, but perhaps something sent in Morse? That does assume all non-sighted ops can read Morse. An alternative would be a dedicated control program for the K3 specifically designed to implement EVERY function of the rig (CONFIG menu and all) and give audible feedback. Again I don't know how that would be done or how best, but I would guess the UI would need to be completely mouse-less. We are so lucky to have the use of the K3 and be sighted, and the great response from Elecraft to all our whims and whines. It wouldn't hurt for us to let that consolidate with use for a while and allow the K3 to be used by those less fortunate than ourselves. 73 de M0XDF, K3 #174 -- A society grows great when old men plant trees whose shade they know they shall never sit in. -Greek proverb On 12 Feb 2009, at 06:49, Don Wilhelm wrote: Bob, > There are 2 'modes' - the first is DATA mode set by the MODE switch, and the second is the type of data mode set by the DATA MD button. > The K3 must be in DATA mode, and to use the paddles for transmit, the DATA mode must be set for PSK D (psk31) or FSK D (rtty). > I am not certain how hams like you and Gary would know the correct setting for the mode and DATA MD unless you first have a sighted helper or other assist to read the display. > 73, Don W3FPR __ 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 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 rear panel question
Gary, I assume the diagrams in the manual didn't make it through the text conversion process. The RCA jack beside the power pole connector is a 12 VDC power output for supplying power to accessories. If you have the KRX3 second receiver, there may be a BNC connector above the power pole connector for a receive antenna for the second receiver. If you have neither the KRX3 or the KXV3, then there are no separate receive antenna inputs on your K3. The 3.5 mm jacks below the RS232 and ACC ports are, from left to right facing the back of the radio: - external speaker (stereo) - headphones (stereo or mono) - microphone input (mono) - line in (mono) - line out (stereo) Note regarding the speaker output: If you set CONFIG:SPKRS to 1, you can use a mono plug. However, if you have CONFIG:SPKRS set to 2, then unless your K3 has the recent AF Output mod fitted, plugging a mono speaker plug into the external speaker output could damage the AF amp chip. The headphone jack does not have this problem; it is safe to plug mono headphones into the headphone jack. As for the line out, if you do not have a KRX3 then only the left channel will be carry an audio signal. 73, Rich VE3KI __ 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 Birdies
Waynes firmware seems to work very well in eliminating "birdies". As he has noted it envolves shifting the 1st LO and BFO slightly [less than 100Hz] which in turn moves the "birdie" some 1 to 2 KHz. As usual Elecraft [Wayne] resolved this likely solution --PDQ-- once the "problem" was identifed/defined. He even made a house call to demonstrate its effectiveness on Wedensday. While it is still in Beta test it appears to provide a reasonable fix. Elecraft will likely release more soon. Thanks Wayne for the prompt response and personal help.

And bring 250VAC into the case of the K3? If a relay is used instead of a solid-state device, it should be located external to the K3 cabinet, especially with 100-250VAC key lines. The output switching device from the K3 can already switch 200VDC at 5A. For those switching medium-voltage AC/DC amp key lines, or want additional rig-to-amp isolation, a more viable option is to use a solid-state external interface. There are several commercial interfacing products available in both assembled and kit form. My personal favorite is the "KeyAll" from Jackson Harbor Press. It is optically-isolated from the rig and will switch 500 VAC/VDC at 2.5 A loads. http://home.att.net/~jacksonharbor/keyall.htm Paul, W9AC __ 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] Custom Skins
Hello Jim: I don’t know of any. In developing any “skin” or other protective enclosure, be aware that the bottom plate of the K2 must be open to free air movement to radiate heat from the 10 watt power output transistors and the top of the K2/100 must have unimpeded air flow, not just away from the black fins of the heat sink itself, but air flows into the back of the K2 driven by the little fan, flows through the 100 watt amp inside and comes out between the heat sink fins at the front. Covering the K2 isn’t an issue for transport, of course, and there is a supplier of very nice carrying bags right here on the reflector, but you can kill the 10 watt and 100 watt power transistors if it’s operated with something around it that restricts air movement. The K2’s external finish is an extremely durable powder coating that is rather hard to damage.

Has anyone done this, and if not does anyone know where such a thing can be developed?

Re: [Elecraft] terminal window in k3 utility
Rich, That is an excellent solution - I don't normally use the K3 Utility Command Tester or Terminal window for things like that, so I just did not think of it. I am more of a 'knobs and buttons' guy except when I am running digital modes. Along that same line, it may be that visually impaired K3 operators may do well to download and study the K3 Programmer's Reference manual to see if issuing commands through K3Utility or other terminal programs would be an easy way to set up the K3 for any particular set of operating conditions. Setting up macros/memories in K3 Utility may also be helpful. 73, Don W3FPR Richard Ferch wrote: > There are software commands that can be used to select any of the K3's four > data submodes. > > The DT0; command selects DATA A, DT1; selects AFSK A, DT2; selects FSK D and > DT3; selects PSK D. > > If you are using the K3 Utility, you can use the Command Tester to send one > of these commands to ensure that the K3 is in the desired data submode. > > 73, > Rich VE3KI > > Don W3FPR wrote: > > >> I am not certain how hams like you and Gary would know the correct >> setting for the mode and DATA MD unless you first have a sighted helper >> or other assist to read the display. >> > > > __ > 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 > > > > No virus found in this incoming message. > Checked by AVG - www.avg.com > Version: 8.0.234 / Virus Database: 270.10.23/1949 - Release Date: 02/11/09 > 08:01:00 > > __ 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 external qro keying line
I've seen numerous posts about the PTT output line on the K3 and using older amps. Yaesu's, Kenwood's, Icom's all share the same issue. Unless you are running QSK and need instant keying, I would suggest adding a small 12v relay inside the K3 that the solid state device keys and presents the user with a set of dry, isolated contacts that can handle positive, negative and up to 250v DC or AC. I have added this to several K3's to protect the switching transistor from eventual destruction. Once again, if you are using QSK, solid state due to it's fast switching time is your only option. Yes, it means touching your K3 with a hot soldering iron, but it's a "pay me now or pay me later" thing, sooner or later it will blow the switch if you are hooking up older or HB amps that use other than low current positive keying voltages.

[Elecraft] CONFIG: TECH MD
Hi John: It's kind of like setting your PC to show invisible files. There's always the chance that you might mess something up that's why it's not recommended. If you're careful when you go into CONFIG you won't mess up any of the more technical settings. If you are the careless type you might want to leave TECH MD off. I like to play around with several different CONFIG settings so I allocated them to special buttons. Then it only takes one push (or one hold) to bring them up. The obvious special function buttons are PF1 and PF2. But if you are not using the M1 through M4 buttons for recording purposes you can also use them for special features. Instructions are in the manual. 73, Mike K2MK On my K3 I often change the AGC -- S setting. I like 5 for general listening, but 20 when I'm net control so I don't miss the weak check-ins. Each time I go through the menu to first set TECH MD on and then after making the change, setting TECH MD to off. Somewhere in the manual it said to turn TECH MD off after you make changes. Is this really necessary? What are the dire consequences of leaving TECH MD on?

[Elecraft] K3 Order
James, Congratulations on ordering your K3! It looks like your list of options are complete and you have been doing a lot of research. You will love your K3 when it is assembled. Suggestions: Be sure you have proper ESD protection when you assemble your K3 and follow the manual carefully. When assembling your K3 you might want to install the DSB board for the KRX3 and the KDVR3 Board before you install the front panel to the RF board. This will eliminate having to remove the front panel later. If you are having the factory assemble your rig, open it up and carefully inspect your radio for any loose modules or parts that may have worked loose during shipping. Afterward run a complete test on the K3. Have fun, you'll love this radio. 73 Dave KD1NA I'm just about ready to place my order for a K3 (hopefully by tomorrow.yay!) After some good discussions with list members, I think I've finally narrowed down my option choices: * K3/100 kit * KAT3 ATU * KBPF3 gen. cov. Module (1 unit, will be placed on SUB receiver) * KDVR3 Dig. Voice recorder * 500Hz 5 pole (2 units, one on each receiver) * 6KHz filter (1 unit, will be placed on main RF board for ESSB experimentation) * 13KHz FM filter (2 units, one on each receiver) * 40Hz filter matching for 2.7 and 500Hz filters * KRX3 sub receiver * KTCXO3-1 1ppm oscillator * KXV3 xverter interface * MH2 hand mic I'm mostly an SSB guy, but do play around with PSK31 and RTTY. I also like to listen to shortwave broadcast stations. The sub receiver will get the gen coverage module plus a 13, 2.7, and 500 filter. The 2.7 and 500 will be matched for diversity receive. The FM filter on the RF board will be used for 10m repeaters, while the FM filter on the sub will be used for broadcast reception. I don't know if anyone here has heard of the AOR LA-390 active loop RX antenna, but I'm thinking this might work well for my diversity experiments. I'm space limited, and this thing can be kept on my window ledge. __ 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

Mac users are simply use to not having many applications available and never think to ask but I'm sure there are many of us out there who look forward to this. On behalf of all of us our many thanks. Paul N1SEZ I guess I'll get busy and finish coding the terminal page. :) Other than a conversation I had with Greg, I don't recall any other Mac users mentioning the Terminal. I find it difficult to put much effort into something that no one will use. Now that I know it's wanted, I'll get it done. In the meantime, for those wanting to work digital modes on the Mac, I HIGHLY recommend you take a look at Kok Chen's cocoaModem. It is, IMO, the finest digital mode application out there - on any platform.

Re: [Elecraft] Terminal for Mac users
I must agree with David Fleming about Cocoamodem - it is the only program I currently use for digital modes - a very easy to use, well-thought out program. Also, if the mac version of the Utility program included the terminal function, I would surely have occasion to use it.

Re: [Elecraft] Specific button feedback (was: terminal window in k3utility)
Hello David, Thanks for your note regarding us blind guys. CW feedback would be excellent and perhaps the simplest solution. I don't want to have a separate firmware program for blind guys because once developed, it may lag the wonderful updates provided in the mainstream firmware. In my humble opinion, CW feedback for the main menu and the configuration menu would FB and by far more than any other manufacturer has ever offered up. 73, Bob K3UL __ 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] How to set loop delay time for KDVR3
Good morning all, Maybe it's just me, but I can't seem te figure out how to set the loop delay time for the digital voice recorder. Can someone point me in the right direction?

[Elecraft] Specific button feedback (was: terminal window in k3 utility)
Perhaps it's time for us sighted ops wanting firmware features and additions etc. to take a step back and give Elecraft some time to introduce some form of feedback for our fellow ops with vision problems. I have no idea what would work best, but perhaps something sent in Morse? That does assume all non-sighted ops can read Morse. An alternative would be a dedicated control program for the K3 specifically designed to implement EVERY function of the rig (CONFIG menu and all) and give audible feedback. Again I don't know how that would be done or how best, but I would guess the UI would need to be completely mouse-less. We are so lucky to have the use of the K3 and be sighted, and the great response from Elecraft to all our whims and whines. It wouldn't hurt for us to let that consolidate with use for a while and allow the K3 to be used by those less fortunate than ourselves. 73 de M0XDF, K3 #174 -- A society grows great when old men plant trees whose shade they know they shall never sit in. -Greek proverb On 12 Feb 2009, at 06:49, Don Wilhelm wrote: > Bob, > > There are 2 'modes' - the first is DATA mode set by the MODE switch, > and > the second is the type of data mode set by the DATA MD button. > > The K3 must be in DATA mode, and to use the paddles for transmit, the > DATA mode must be set for PSK D (psk31) or FSK D (rtty). > > I am not certain how hams like you and Gary would know the correct > setting for the mode and DATA MD unless you first have a sighted > helper > or other assist to read the display. > > 73, > Don W3FPR __ 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
