Re: [Elecraft] BFO resets itself after cal fil (K2)
Aha! Then I did not fully understand the inner workings of the K2. I just looked att the schematics and noticed the BFO and the mixer. Out of that I made the conclution that the BFO value must change the pitch. So what you are saying is: During filter setup, it is normal for the pitch to change but when I press XFIL the save-routine inside the K2 is compensating for the change and restores the pitch to its original position?

Of course, if you move the BFO enough, the signal will no longer be inside the passband. You must move the VFO to change the pitch, just changing the BFO will not do it.

Re: [Elecraft] PACTOR iii
Pactor III is 2.4 KHz bandwidth, not 5 KHz. However, various other modes plague of the amateur bands, it is not confined to Pactor III. I See ROS stations sending out beacon/CQ calls endlessly in the hope of someone reporting their signals with a link back via the internet. Even the lowest symbol rate of ROS spreads 2 KHz on most frequencies, that is 4 characters per second taking up 2 KHz! Pactor, like Amtor before it, has it's place as a 2 way communications tool and can take up little bandwidth (P1 or 2, that is), it even makes for an excellent means of chatting on the keyboard between two stations. Unfortunately, most of the activity here in Europe seems to be stations calling into the Winlink network to send pictures (split into several parts) into the internet and exchange e-mail of a non ham radio nature. For some bizarre reason officialdom seem to turn a blind eye to it... Perhaps more so than packet in the past. On an Elecraft note, my K3 works well on ROS, Amtor and Pactor (I, II and III). My KPA500 even switches fast enough to use it on Amtor! 73 Dave -- Of course once it finds a PACTOR III box and opens up the full bandwidth the PACTOR-bot wipes out 5 KHz in a flash. SNIP ...

[Elecraft] Noise from compressor
Riddle me this! I have strong interferance since installing an air source heat pump. It is most annoying on 20M. It is also present on 40M and 15M. My 40M antenna is twice as far from the compressor and the noise on that band is reduced. On 20M is is S3-4. It used to be S1. Here is what I have done in trying to eliminate this problem: 1. I removed the 220VAC from the compressor at the breaker panel. The noise is gone. 2. I turned the breaker back on and put my indoor units on fan only. The noise is gone. I guess this proves the noise is coming from the compressor. Also when I turn my beam toward the compressor the noise increases. 3. I disconnected my power supply and connected the K3 to a battery. The noise is gone so It is not coming in on the house AC circuit. 4. I disonnected the antenna at the K3. The noise is gone so it seems it was coming from the antenna. 5. I reconnect the antenna and turn the RF gain to zero. The noise is gone from the speaker but on the waterfall it is NOT gone. I am hearing a buzz in the speaker or headphones and can see many vertical lines on the P3 waterfall. The wider my bandwidth setting the more noticable problem but the lines are there for the entire width of the P3 scan. Maybe 40 lines on P3 display with a 5 khz scan width. I have tried placing 3 capacitors across the 220VAC terminals where it connects to the compressor. LG, LN, NG with no measureable results. I would be very happy if someone can shed a little light on this. 73, -Robby VY2SS So the noise is present in the IF -- View this message in context: http://elecraft.365791.n2.nabble.com/Noise-from-compressor-tp7513403.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

Re: [Elecraft] Noise from compressor
Hi, Robby — The noise is very likely coming from the pulse-width modulation (PWM) circuitry that runs the blower motor located in the air handler enclosure (often located in the attic or on the top floor of a residence). In poorly designed and shielded circuits the noise can escape from that enclosure out into other parts of the A/C system — riding on wiring to the thermostat(s) on the walls and on power leads to the outdoor unit. In one installation I saw, the air handler enclosure in the attic provided a very good shield, preventing direct radiation from the circuit. However, the high frequency energy from the PWM was leaving the enclosure and radiating to nearby antennas via the thermostat wiring (and to a lesser degree, the power wiring to the compressor). At least one manufacturer sells a kit (priced in the $100-$200 range, plus local labor) that is meant to be installed at the air handler by one of their authorized dealer's techs. Whether it's effective or not, I can't say, and you might be able to convince them that as a long-time radio amateur you can do the installation yourself. Be very careful about assumptions as to the source of the noise; so much of the wiring between the various components of the A/C system is unshielded that it's hard to say for sure until you do some detailed sniffing with an AM radio or other suitable detector. I doubt, for instance, that an HF beam can distinguish between the direction to the compressor and the direction to portions of your interior wiring. In the system I mentioned above, in that residence the peak noise pickup was around the thermostat on a hallway wall on the first floor of a two-story (plus attic) building. You'll probably do better with this kind of question on the RFI reflector. I suspect the K3 is incidental to the issue. Bud, W2RU On Apr 30, 2012, at 8:20 AM, Robby.VY2SS wrote: Riddle me this!

[Elecraft] Connect your radio and computer wirelessly
This popped up on the KX3 reflector but I thought it should be here too. Pardon if someone beat me to it. Here's a neat new device that connects your computer and radio over an ad hoc wireless network. It is really designed for the iPad and the maker's program HamLog but I see it having application here. Communication with the computer is wireless and communication with the rig is over its serial port. No USB or serial port from your computer is required. 1. Take your iPad to the field and log your contacts with HamLog, then import them into your home logging program (yes the program supports ADIF file transfers). HamLog supports Elecraft radios, including the KX3. 2. Maybe you've had bad luck with ProLific and FTDI drivers trying to run USBSerial converters. You could have your radio and computer talk wireless while you access the internet over a network cable. Go to pignology.net I have no connection with the company - just interested in the possibilities and marveling at the creativity. -- Buck k4ia __ 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] JT65HF -- Data Mode A
John, What are your filter settings? The default filter settings in DATA A are Fc = 1500 Hz, width = 500 Hz. The JT65 sub-band is 2 kHz wide, centered at 1270 Hz, so with the default DATA A filter setting you will only be able to copy a small fraction of the sub-band and therefore only a small fraction of the signals that are on at any time. Your K3's filter width should be set to 2.5 kHz or so to cover the whole JT65 sub-band. 73, Rich VE3KI N9KW wrote: I recently downloaded JT656HF by W6CQZ and have on several occasions monitored 14.076 \ MHZ with my K3/Signalink USB using this software.

When I first got the P3 I did not like the U shaped cursors, but now that I have a larger display for the P3 I find I like the U shaped cursors better for weak signal work because they don't hide the smaller RF signature of the weak signal. If I didn't have the SVGA board I would and still do use the vertical cursors. Now I'm looking forward to mouse controlled QSY on the SVGA screen.

When I first boot everything up, I have my P3 set up to display both waterfall and bandscope displays. However, the P3SVGA only shows the bandscope display. I have to turn the dual display off then back on again in order to get both displays via the P3SVGA. Also, my frequency markers on the SVGA display are reduced to a 1-pixel wide line instead of the broader green and purple markers. Is anyone else seeing this? Right now it is just a minor inconvenience, but it would be nice if this gets fixed in the next firmware version.

Re: [Elecraft] BFO resets itself after cal fil (K2)
Thank you for the help.

The use of a broadband noise source and an audio spectrum analyzer application running on the computer soundcard will make K2 filter setup easy and uncomplicated. 73, Don W3FPR On 4/30/2012 2:49 AM, Erik Linder wrote: Aha! Then I did not fully understand the inner workings of the K2. I just looked att the schematics and noticed the BFO and the mixer. Out of that I made the conclution that the BFO value must change the pitch. So what you are saying is: During filter setup, it is normal for the pitch to change but when I press XFIL the save-routine inside the K2 is compensating for the change and restores the pitch to its original position? Is that correct? Which in practice means that I cannot adjust the pitch manually (like on an old radio), it's up to the K2 routine to set the pitch. ./Erik 2012/4/29 Don Wilhelmw3...@embarqmail.com Erik, The K2 will preserve the pitch when the BFO is changed. Of course, if you move the BFO enough, the signal will no longer be inside the passband. You must move the VFO to change the pitch, just changing the BFO will not do it. The filter passband edges will change, but the pitch of a tuned signal will not. That is why it is important to use a broadband noise generator (often band noise will do) and some type of audio spectrum analyzer (I use Spectrogram) to view the shape of the passband - you can see when it is centered at your target pitch. Use no signals in the passband when changing the filters, having signals present will only confuse your view of the passband shape and positioning. If you need Spectrogram, you can find it on my website www.w3fpr.com - look near the bottom of the opening page. 73, Don W3FPR On 4/29/2012 4:40 PM, Erik Linder wrote: Don, tnx for the answer.

But if I want something more narrow I like to use FL2 - FL4. And now I know that I can get in 20 or so Hz if I work hard enough. :-) But the main problem here is that I cannot adjust my filters at all right now. :-( I can move the BFO (change the pitch) as long as I am in cal fil but as soon as I save the filter and return to listen the pitch has changed to default. The BFO-value _has_ changed, it _has_ been saved. (I see the display showing BFO freq for a short time). But still - the pitch is where it was before I changed the BFO-value. And I have changed it much - like 50 to 100 units. USB, LSB, CW - the mode does no difference. So: Received pitch of the signal transmitted from my 2:nd TRX: 1500 Hz The BFO value is (lets say) 128 I change the BFO value too 100 I hear (and see on the waterfall) that the pitch is changing. I press XFIL (to save) Display shows BFO freq for a short time. I press XFIL a couple of times to get round to FL1 again. The pitch has now jumped back to 1500 The BFO-value is at it's saved 100 I can now lower the BFO value once more and when I come around the pitch will be 1500 and the BFO is saved with the new value. Isn't it suppose to work like: Change the BFO to get the correct pitch Save Return to the filter and the pitch is where you programmed it to be. __**__**__ Elecraft mailing list Home: http://mailman.qth.net/**mailman/listinfo/elecrafthttp://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.**htmhttp://mailman.qth.net/mmfaq.htm Post: mailto:elecr...@mailman.qth.**net 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/elecrafthttp://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.**htmhttp://mailman.qth.net/mmfaq.htm Post: mailto:elecr...@mailman.qth.**net 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] Loading inductor Question
Ken: Toroidal cores have many fine qualities for loading coils. Of course not all core have the same qualities so be sure you have the right Al rating. You will want a low rating. Also remember you will lose those fine qualities if you saturate them so be sure your core is big enough for 250 watts (2.5x safety margin). I use Teflon wire on mine for lower losses. Finally, it is very difficult to tap a toroid whereas coil taps are easy on an air core coil. Don't use toroids if you need taps. 73 Fred, AE6QL -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Ken Alexander Sent: Monday, April 30, 2012 8:15 AM To: Elecraft Subject: [Elecraft] Loading inductor Question Folks, Given that inductors on toroid cores are used extensively in autotuners, is there any reason (assuming I choose the right size core, made of the correct material for the application and winding it with the right size wire) for not using one as a base loading inductor on a vertical antenna?

Re: [Elecraft] Loading inductor Question
Ken - A toroidal inductor should work fine, it is understood that the core must be of the proper material and size to handle the expected power and frequency range. Keep in mind that many of the automatic tuners use toroidal inductors in their design. There is some advantage to having the loading inductor out in the air, as it dos radiate somewhat, but the convenience and practicality of an actual design may dictate that the inductor (s) be enclosed. Being a conservative sort, I would tend to use bigger cores and larger wire sizes that an absolute engineering solution might dictate, mostly for safety factor and insurance against core saturation when handling unusual situations. - Jim, KL7CC Ken Alexander wrote: Folks, Given that inductors on toroid cores are used extensively in autotuners, is there any reason (assuming I choose the right size core, made of the correct material for the application and winding it with the right size wire) for not using one as a base loading inductor on a vertical antenna?

Re: [Elecraft] Noise from compressor
On 4/30/2012 6:13 AM, W2RU - Bud Hippisley wrote: The noise is very likely coming from the pulse-width modulation (PWM) circuitry that runs the blower motor located in the air handler enclosure (often located in the attic or on the top floor of a residence). In poorly designed and shielded circuits the noise can escape from that enclosure out into other parts of the A/C system — riding on wiring to the thermostat(s) on the walls and on power leads to the outdoor unit. In one installation I saw, the air handler enclosure in the attic provided a very good shield, preventing direct radiation from the circuit. However, the high frequency energy from the PWM was leaving the enclosure and radiating to nearby antennas via the thermostat wiring (and to a lesser degree, the power wiring to the compressor). This is an excellent description of what is likely the mechanism causing your problem, and so is Bud's suggested solution. This is yet another example of the manufacturer leaving out the parts needed to prevent RF noise. In this case, they even have the balls to charge extra for them. I also concur that the RFI reflector is a good resource for this kind of problem.

INMARSAT has a service that requires minimum equipment and may by now, have internet hook up available.

John Bohnert wrote I recently downloaded JT656HF by W6CQZ and have on several occasions monitored 14.076 MHZ with my K3/Signalink USB using this software. I am still in the process of trying to set up the software and gaining an understanding of how to use it. I experience the following: 1) If I set my K3 in data mode A, no decoding of JT65 signals occurs during the 12 second decoding period, but 2) if I set my K3 in the USB mode, decoding of the JT65 signals does occur in the 12 second decoding period. I have not tried any transmissions. I would appreciate any advice/solutions so that I can use data mode A with JT65HF. I use the K3, Signalink USB and FLDIGI on a regular basis for PSK31 with data mode A and have not had any problems. N9KW John Hello John, First of all I would highly recommend you try asking JT65-hf related questions on the jt65...@googlegroups.com list. Their list is totally dedicated to helping folks with the JT65-hf software. You can join it here: https://groups.google.com/forum/?hl=enfromgroups#!forum/jt65-hf That said, I run my K3 with a SignaLink USB and JT65-hf on Windows 7 I also bought the SignaLink cable for the K3, so I can use the rear jacks. I'll address your 12 second comment first, then give you a few pointers after that. I'm assuming when you say 12 second you are referring to the, 48-60 second, section of a minute. There should be 'NO' signals during that time. If there are, your computers time sync with NTP is wrong. Anything above 2-3 seconds off 'nothing' decodes 'any' time during the entire 60 seconds. The only time you should see any signals in the waterfall is between 0-48 seconds, then there is a 12 second quiet time. (good opportunity for setting the volume levels in JT65-hf so they read 0 in receive) (top left in the JT65-hf window, where it says Audio Input Levels) Time syncing you computer is 90% of the problem with bad/no decodes To much receive signal strength is the other 10% (above 4 or 5 it goes into the red to show rx is to hot) Meinberg is good for setting your clock http://www.meinberg.de/english/sw/ note: the internal Windows time sync is NOT accurate enough for this task! === Settings for JT65-hf operations with the K3 and SignaLink USB. K3 in DATA mode A, (which for the K3 defaults to USB) Data A also sets the K3 so there is no compression during transmit. If you use straight USB mode there may/will be distortion on your signals. While in DATA A, set the MIC knob (lineout level) to Line 10-20 if this needs to be any higher, you can jumper JP3 in the SignaLink. JP3 – This jumper can be installed to increase the SignaLink USB’s Transmit Audio Signal. In Receive, under MAIN CONFIG menu, the LIN OUT is set to [nor 010] If the volume is to low you may need to jumper JP2 in the SignaLink. JP2 – This jumper can be installed to increase the Receive Audio signal going into the SignaLink USB’s built-in sound card. the above settings interact with TX RX controls on the SignaLink Set the K3 as above, then use the TX RX knobs to tweak the levels needed for JT65-hf to work. For TX I set the K3's PWR where I want (say 5w) MIC knob (lineout level) is set to Line 10-20 then turn the SignaLink TX up til I get the K3's ALC to the 5th bar For RX I set the K3 MAIN CONFIG menu the LIN OUT is set to [nor 010] then the turn the RX on the SignaLink USB up so the reading for the JT65-hf 'Audio Input Levels' shows L 0 This is set with no signals being received, like during the time between 48-60 seconds. In JT65-hf rig control, I use DXLabs Commander. I set the width of the K3's filter to 2.0khz and if you have a P3 set it's span to 3khz In Windows 7 under the 'recording devices' for the SignaLink USB properties are set to: Listen to this device NOT checked Power Management set to 'Continue running under battery power' Microphone level '37' 1 channel, 16 bit, 44100 HZ (CD Quality) Exclusive Mode 'both' boxes are checked ** side note, I was just trying RMS Express for WinMor and after 3 days figured out the SignaLink USB's DLY MUST be set down to off. So it could possibly be the cause of some problems, on some other modes ** I have found you can use much less power in TX than you might think. I have only short verticals (7-9' tall) on 10-20m I may have to run as high as 20w to get to Russia or S. Africa from Texas. But otherwise I make most contacts with 1-5w. Using a 7' tall vertical on 160m and 20w (1.2w ERP) I made a QSO with California receiving a -14 report.

Re: [Elecraft] N9AA
Yes, I guess you could say I am a new ham, having only been licensed since 1977. Despite this, I've sent and delivered a few hamgrams, and the difference between them and Pactor is that a ham had to be the intermediary, as opposed to sending a communication directly to someone who is not licensed. The same was true of the NTS, so these are not analogous with Pactor or any of the other automated email forwarding modes. I really can't understand why people don't get the distinction, because it really isn't all that subtle.

Re: [Elecraft] question for psk31 users
Gerald, Ron and all, CAUTION: That document's rig setup is incorrect for Elecraft gear. Following the transmitter setup described in that (and many others on data modes) will not allow the K2, K3 or KX3 to function properly. and may (in fact) may create a distorted signal - it is a sure way to create power creep on your digital signal. You must first set the audio drive power For the K3 (or KX3) set to DATA A submode and either turn the power down or turn in TX TEST. Now adjust the audio until you see 4 bars solid on the ALC meter - the 5th bar could be flickering slightly (this is NO ALC for the K3 and KX3 -ALC starts at the 5th bar) For the K2, adjust the audio until you see an ALC indication, and then turn it back a bit. That is it - adjust the *desired* power level with the power knob and operate. Setting the power level to max and using the audio drive to bring the power up to the desired level will work with transceivers that do not use a feedback control loop to set the power level - the K2, K3 and KX3 *do* use a feedback loop, most other transceivers just adjust the drive and take whatever comes out of the PA stage. 73, Don W3FPR On 4/30/2012 2:34 PM, ron wrote: On 04/30/2012 02:06 PM, KC6CNN wrote: I am now up and running on psk31.

Re: [Elecraft] question for psk31 users
Gerald, You do not say what type interface you're using (i.e. SignaLink, RigBlaster, etc.). Regardless, sidebars on your signal is indicative of you overdriving your transmit audio - not too much power. As long as I do not overdrive my transmit audio, I can run 100W without sidebars and do so regularly on WINMOR. Check your ALC. It should be not more than four bars with a flickering fifth bar. On my SignaLink, I adjust my transmit audio with the TX pot on the front. I can tweak it a bit with the mic gain. 73, Joel - W4JBB On Apr 30, 2012, at 13:06, KC6CNN kc6...@gmail.com wrote: I am now up and running on psk31. I had my power set to 25watts and all is well.

Do not use the MicroHam interface for loading firmware - that is when you need your USB to serial cable connected to the P3 in place of the MicroHam interface RS-232 cable. 73, Don W3FPR On 4/30/2012 6:13 PM, Joe Subich, W4TV wrote: microHAM interfaces *replace* any other connection to the computer.

Re: [Elecraft] Fw: KPXA100 amp for KX-3
Bob, Sorry, but none of that information is not yet available. As far as size, I can make a wild guess based on the volume of a typical 100 watt amplifier and 100 watt tuner and say that the total volume will be similar to that of a KPA100 plus a KAT100 - which fit inside an Elecraft EC2 enclosure. It will be but I doubt if the process is far enough along that the projections you are asking about can be available. I am certain Eric will correct me if I am wrong. BTW - a nit - there are no dashes in Elecraft model numbers except for a couple of the mini-modules. 73, Don W3FPR On 4/30/2012 6:26 PM, Linda and Bob wrote: See message below - Original Message - From: Linda and Bobdlrwi...@verizon.net To:elecraft@mailman.qth.net Sent: Monday, April 30, 2012 12:40 PM Subject: KPXA100 amp for KX-3 Does anyone know the approximate weight, size (HxWxD) of the KPXA100 for the KX-3?

Re: [Elecraft] Fw: KPXA100 amp for KX-3
Some time last year Eric or Wayne gave an approximate idea of size and weight they had in mind back then. I am presuming the K2 and K3 amps/tuners are a good volume/weight predictor just need to be re-laid out for the KX3. the two together was something like 4 x 5 x 9 and 6 pounds as an idea back then I thought. 73, tom n4zpt On 4/30/2012 6:47 PM, Don Wilhelm wrote: Bob, Sorry, but none of that information is not yet available.

[Elecraft] KX3 Receive Isolation Amp: When to use it
Like all zero-I.F. (or nearly zero I.F.) transceivers, the KX3 radiates a small amount of local oscillator (L.O.) energy backwards: through the mixer, and out the antenna jack. Normally this is not a problem. However, if you have another rig in the same location, with the two antennas not far apart, you'll hear the KX3's L.O. signal when both rigs are tuned to the same frequency. If this is a problem, all you need to do is turn on the KX3's isolation amp. This has no impact on performance, but it does add about 15 milliamps to receive-mode current drain, so you should only do this when necessary. The isolation amp is turned on using the RX ISO menu entry. 73, Wayne N6KR __ 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] Fixed audio output missing on the KX3?
I was going thrugh the manual today, and it seems that a fixed audio output is missing entirely from the KX3, why? Fixed audio output is important for us who routinely run digimodes. There is also a lack of a separate audio input, which is just as important when running digimodes. So to run digimodes, it seems to me that I will have to disconnect the microphone and connect a suitable audio interface to the mic connector, and also to the speaker/headphone output, then I need to adjust the mic gain and the speaker volume on the KX3, and then do similar adjustments on the interface/PC. Quite cumbersome, when it all should have been included in an ACC connector on the KX3. Both the FT-817 and the IC-703 have miniDIN connectors on the back with audio in, audio out and PTT, something similar would have been a big advantage on the KX3 when running digimodes. When microphone and headphone jacks are used for digimodes, it will mute the speaker, and it will make it take unnecessary long time to change from digimodes to SSB/CW and vice versa. Yes, I know that the KX-3 utility program supports CW, RTTY and PSK-31 through the digital interface, but that program is kind of limited in functionality and modes. On the FT-817 and IC-703 and others as well, it's just a matter of changing the frequency and the mode (if the Data modes are employed). I think this is a real shortcomming on the KX3! Will it be possible for a future upgrade to the KX3 to install a miniDIN (or a separate jack) to accommodate a fixed level audio output, audio input and PTT input? (Yes, I understand that drilling or case replacement will be involved is such an upgrade.) The best upgrade will of course be a built-in USB Interface with and integrated USB sound card, like the IC-7600, TS-590 etc...

Why settle for KX3-2M? Why not KX3-2M/70cm? This pretty much says it I think. Why settle for only 2 m, why not also include 70 cm in the KX3-2M? With a 2 m and 70 cm module available the KX-3 will complete replace the FT-817, at least in my travel kit.

Re: [Elecraft] Why settle for KX3-2M? Why not KX3-2M/70cm?
Hi Martin, A 2-m module is difficult enough given how little space is available. We'd like to do other VHF/UHF bands, but I'm not sure if it's possible. It would be fun to try. 73, Wayne N6KR On Apr 30, 2012, at 4:35 PM, Martin Storli - LA8OKA wrote: Why settle for KX3-2M? Why not KX3-2M/70cm? This pretty much says it I think.

Re: [Elecraft] Fixed audio output missing on the KX3?
Martin Storli - LA8OKA wrote: It seems that a fixed audio output is missing entirely from the KX3, why? Hi Martin, Our goal was to make the KX3 the smallest, lightest, most portable all- band/all-mode radio ever. We had to draw the line somewhere on features, battery size, number of controls, I/O connectors, etc. Included are features that felt would be used most often in portable settings. Audio-based data modes are a good example: we fully support these modes, but as you pointed out there's the small inconvenience of sharing audio I/O with headphones and speaker. On the other hand, PSK31 and RTTY can also be supported by the KX3 with nothing but the serial port (using ASCII send/receive commands). So we're providing a very usable alternative for the two most popular digital modes. You can use the Terminal function in KX3 Utility, running on PC/Mac/Linux, to do full data communications in CW, RTTY, and PSK31 modes. I don't think we can support digital audio data over our serial port, but if figure out how to do it, I'll let you know. 73, Wayne N6KR __ 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
