[Elecraft] K2 Distorted TX audio on 10m and 12m only
My K2 sounds fine on all bands on all modes, both TX and RX except for 10 and 12m. On those two bands, RX is fine, but TX sounds horrible on all modes, LSB, USB, and CW. It puts out full power though. Any ideas? I'd really like to use this at field day. Of course 12 and 10 probably won't even be open...

[Elecraft] RE: K3 full power strange behaviour
When running ARQ Pactor with my K3, I notice the power level seems to wander requiring the mic level to be adjusted, this is noticeable as a change in ALC indication. I suspect those running sound card data modes may also see a similar variation in ALC levels. Note, I am not running power levels any higher than 50 Watts, usually 15 - 20 Watts. By comparison, a TS-480 doesn't vary at all. Dave, G4AON K3/100 #80 I also noted this with my K3 last week. My guess is that this is a burp in the latest firmware. I tune my amplifier with a string of dots (abt 30 wpm) and note the bar graph takes about a second and a half to indicate an accurate power level... Anyone else seeing this??

Ok I lied about the full power part. 12m doesn't make squat for power and 10m makes WAY more than it should. On 10m, with power set to 2 watts, as per the alignment procedure, I measure 7 watts out on my bird. With power set to 10 watts, I measure 18 watts out!! On 12m, with power set to 10 watts, I measure 3 watts out.

RE: [Elecraft] K3 full power strange behaviour
Just been operating cw on 80m at 100w and after a while of 'everything normal' I noticed the power dropping and then coming back up...one time it went as low as 24w and then jumped back up. Power indication on VFO B follows the power drop, SWR seems ok but I confirmed it was doing same into a dummy load; PA temp was showing about 39 C only.

I don't normally use MixW any more but I just fired it up to check, and it seems OK to me. With the transceiver set to 14.072.000 MixW is showin exactly that in its frequency display window, and the waterfall is showing a chunk of band centered on 14071, which is correct assuming that the K3 uses LSB in data mode. The K3 was erroneously reporting the data modes as reversed, and this was corrected in the latest firmware release. I suspect that this might have something to do with your problem, but since I can't see the problem myself I'm not sure what it is. Perhaps you used the options in the CAT setup screen to compensate for the previously incorrect frequency offset, and now need to take that settimg out.

I've seen the thread on the cw keys/keyboard etc to cw-psk. I'm pretty confident that I'm correct in saying no, because I think the K3 is the only radio that supports this. Unlike RTTY, which as been around long before sound cards were invented, PSK31 was designed as a sound card mode. So there is not even any legacy software that can do this. Since this would require a second serial port I doubt if such an option would be popular, especially as there is doubt in my mind as to whether the USB serial ports most people would want to use are capable of working at the nonstandard baud rates such modes would require. Under Windows you would probably have to fight with the system to get access to the serial ports and set these nonstandard UART parameters, making the task much more difficult than it was in 1986 when I wrote my own MS-DOS RTTY terminal program. My new K2/K3 logging program KComm can use the same KY software commands to generate RTTY and PSK31 when the K3 is in FSK D and PSK D modes. But there are a number of issues that need to be addressed in the firmware before this becomes usable on-air, to whit: - KY currently only supports the CW alphabet so you can't send newlines or backspaces (nor a lot of other characters that are valid in PSK31), and in PSK31 everything is sent in lower case. - There is no way to abort the transmission of text that has already been sent to the radio (as there isn't in CW if you have selected the option to send @ as a prosign instead of using it as an abort character.) - Julian, G4ILO K3 s/n: 222 K2 s/n: 392 G4ILO's Shack: www.g4ilo.com KComm for K2/K3: www.g4ilo.com/kcomm.html -- View this message in context: http://www.nabble.com/K3-PSK-D-tp18153773p18154526.html Sent from the Elecraft mailing list archive at Nabble.com. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] K3 Firmware 2.10,1.81 problems Update
Dear All, did some more on the problem. With MixW using modes RTTY or RTTYR when controlled by a K3 in data mode the frequency scale moves to the right but the signal moves to the left. They should obviously be in step i.e the display should show a signal at a constant frequency as the radio is tuned. This works correctly in USB and LSB. MixW thinks the radio mixer frequency is on the opposite side of the signal to reality. To attempt to solve the problem I reloaded the K3 software; no change. I then went back to the-non beta 2.02 etc software; everything now working correctly. I am pretty sure that this is a real problem but maybe only for MixW users using the RTTY modes. It is a problem for us though, because by using USB or LSB modes in MixW automatically switches the K3 to the same modes. This prevents use of the K3 data mode features such as prevention of compression and other data special settings. Julian (G4ILO) thanks for your interest. All my CAT corrections are zero in MixW also. Interesting that you say there was some change in the last release - K3 was erroneously reporting the data modes as reversed This looks very much like the problem but in the case of RTTY it seems it was correct but is now incorrect.

Re: [Elecraft] K3- what a radio!
This is what I wrote recently to someone who asked me how I liked the K3 (which I have had about a month now): The K3 is a really wonderful rig. I’m trying hard to think of any cons right now but none come to mind. The list of pros includes: Very quick auto tuning (KAT3) – like 1 to 2 seconds to find a match. It finds a 1 to 1 match on 160 to 6 meters with a Cobra Ultralite antenna and BL2 balun. Great sounding received audio – and that AFX button is fun. Unbelievable noise reduction and noise blanking effectiveness. Unbelievable selectivity and adjustment range. Up to 120W output (but I run it at 100W). Accurate internal SWR and power meters. Great general coverage receive. Excellent QSK – better than the K2 – as good as the TS-930S. The reports on the transmitted CW note are terrific. Many parameters are adjustable – AGC settings, AFX delay, NB sensitivity and width, keyer weight, etc. These may take time to find the optimal settings. (maybe that’s a con hi hi). The size and weight are perfect for my shack. Next week, I’ll update my photo on QRZ.com. Software updating is very quick and easy. I bought their KUSB adaptor since I don’t have a serial port on the home PC now. Many new features will be introduced via software updates. I am hoping for Automatic Character Spacing in the keyer like the Accukeyer and CMOS Logikeyers. Like the TS-930 with the Piexx digital board, there are 100 memories, + another 4 per band. I have never had a 6 meter QSO and the tuner found a match on that band for my antenna. I heard some stations on around 50.098 MHz and called “QRL?” and someone said “Yes” so I know I am getting out hi hi. But no QSO yet. Elecraft support is really great and they bend over backwards to make sure problems are resolved. I started out with a switching power supply (12V, 24A) but I did not like the noise it generated in the receiver and it also induced problems on the transmitted signal. So I bought an Astron RS-35A and that works very well. The power supply is slightly bigger than the rig, though hi hi. 73, John W2XS ni0c wrote: It's the best radio I've ever owned, and it is all that I expected over the four month wait period!

In my version of MixW the radio type is set to Elecraft K2. There is no K3 option. The K2 option was a derivative of the Kenwood option, in fact it is listed under Kenwood on the CAT selection dialog. I was one of the first K2 owners to use MixW, many years ago. Unfortunately my memory now is not very good, but I seem to recall that I originally had the exact same problem as you with the K2 and MixW. I think that the K2 used opposite sidebands to the Kenwood radios (and probably to the K3 as well.) I emailed Nick, the developer of MixW, about it, and he fixed it in the next release. So if my supposition is correct, the K2 option in MixW works right for the K2, but not for the K3. I think MixW needs to be corrected to work with the current K3 firmware, which is now correctly reporting the data modes in software to correspond with what is shown on the front panel. In the meantime, you might find that switching to the TS-2000 option solves the problem. I very much doubt if MixW uses any commands that are exclusive to the Elecraft radios, so this is almost certain to be OK. - Julian, G4ILO K3 s/n: 222 K2 s/n: 392 G4ILO's Shack: www.g4ilo.com KComm for K2/K3: www.g4ilo.com/kcomm.html -- View this message in context: http://www.nabble.com/K3-Firmware-2.10%2C1.81-problems-Update-tp18154703p18155195.html Sent from the Elecraft mailing list archive at Nabble.com. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[K3] [Elecraft] [k3] Wattmeter calibration
Finally I got round to checking the wattmeter calibration as I've felt it's been giving out power levels below what the wattmeter on the front panel reports ever since I've had it. First alerted when my Acom 1000 seemed to giving low output until I saw the amp's input reporting a significantly lower driving power eg 35w as against a K3 setting of 45w into a dummy load. Also 2 independant power meters seemed to agree even though admittedly they weren't lab standard. So I did the configuration while measuring voltage across a dummy load with my 40MHz 'scope and found I needed to wind the WMTR HP setting way down to minimum (010) to get the power up to 50 watts on the 'scope (and yes I did remember the RMS to peak conversion ;-). Seeing that the default setting is 100 I thought I might ask others what setting seems to be the norm. Needless to say I've not noticed anything odd about running 80 or 85 watts instead of 100 these past few months but (wrong) numbers do have a habit of bugging you eventually 73, Stewart Rolfe, GW0ETF (K3 145) -- View this message in context: http://www.nabble.com/-k3--Wattmeter-calibration-tp18155295p18155295.html Sent from the [K3] mailing list archive at Nabble.com. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K3 Firmware 2.10,1.81 problems Update
No, the TS-2000 option doesn't work either. I have a feeling that the issue with the K2 that I referred to affected only certain bands, where the K2 switched the sideband used by default. It only became apparent to me because I used a macro to bring a selected signal to the center of the passband and on some bands the signal moved the wrong way. I can't find an option that works right with the K3 at the moment. However, the K3 is now correctly reporting the data modes as mode 6 = normal and mode 9 = reversed, as defined in the reference manual. Previously it had them reversed. I think that rather than redefine the mode values so that they are the opposite of the K2, MixW needs to be updated. I expect that Simon has already updated HRD to take account of the change, as he was told about it a couple of weeks ago. - Julian, G4ILO K3 s/n: 222 K2 s/n: 392 G4ILO's Shack: www.g4ilo.com KComm for K2/K3: www.g4ilo.com/kcomm.html -- View this message in context: http://www.nabble.com/K3-Firmware-2.10%2C1.81-problems-Update-tp18154703p18155536.html Sent from the Elecraft mailing list archive at Nabble.com. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [K3] [Elecraft] [k3] Wattmeter calibration
GW0ETF wrote: Finally I got round to checking the wattmeter calibration as I've felt it's been giving out power levels below what the wattmeter on the front panel reports ever since I've had it. First alerted when my Acom 1000 seemed to giving low output until I saw the amp's input reporting a significantly lower driving power eg 35w as against a K3 setting of 45w into a dummy load. Also 2 independant power meters seemed to agree even though admittedly they weren't lab standard. So I did the configuration while measuring voltage across a dummy load with my 40MHz 'scope and found I needed to wind the WMTR HP setting way down to minimum (010) to get the power up to 50 watts on the 'scope (and yes I did remember the RMS to peak conversion ;-). Seeing that the default setting is 100 I thought I might ask others what setting seems to be the norm. Needless to say I've not noticed anything odd about running 80 or 85 watts instead of 100 these past few months but (wrong) numbers do have a habit of bugging you eventually I was a bit worried about doing this setting as I didn't have any accurately calibrated wattmeter other than my home made QRP ones. In the end I used my DL1 module. It didn't seem to mind handling 50W for the few seconds needed to get the reading on my voltmeter. I think the lowest I needed to wind the setting down to was somewhere in the 70s. If I'd had to go down as low as 10 I would have worried that there was something wrong with my calculations. - Julian, G4ILO K3 s/n: 222 K2 s/n: 392 G4ILO's Shack: www.g4ilo.com KComm for K2/K3: www.g4ilo.com/kcomm.html -- View this message in context: http://www.nabble.com/-k3--Wattmeter-calibration-tp18155295p18155740.html Sent from the [K3] mailing list archive at Nabble.com. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

I calibrated my K3 power meter against a calibrated (bought assembled calibrated) LP100 that is only a few months old. My WMTR HP calibration is 062. You mentioned the Acom 1000, I also have one of those. On mine (and it was mentioned in one of the reviews as well), the digital power level displayed on the Acom is over optimistic by quite a margin.

All part of having computers and radios mixed together. :-) I know that may not be a satisfactory answer but, I just don't worry about it since it doesn't affect how my K2 operates.

RE: [Elecraft] K2 Distorted TX audio on 10m and 12m only
Hi Jeff: First, note that 12 meters (along with 60, 30 and 17 meters) will NOT be used for Field Day. Those bands are off limits to contests. But your K2 should work fine there and on 10 just the same. Does this occur with a good dummy load attached? That sounds a LOT like RF feedback. Such feedback is often much worse on higher frequencies. The same basic audio/modulator stages of the K2 are used on *all* bands, so if your audio is good on the lower bands, they are working properly. The other possibility is some sort of instability in the output stages on the higher frequencies. That is quite unusual in Elecraft rigs, but when it happens it is often the result of a poor load at the antenna. Again a dummy load might identify that by making the problem go away. When checking with a dummy load. Be certain you have a good 50 ohm coaxial cable between the rig and the load (it's a good idea to use a different cable). Ron AC7AC -Original Message- My K2 sounds fine on all bands on all modes, both TX and RX except for 10 and 12m. On those two bands, RX is fine, but TX sounds horrible on all modes, LSB, USB, and CW. It puts out full power though. Any ideas? I'd really like to use this at field day. Of course 12 and 10 probably won't even be open...

[Elecraft] K3: Problems using N1MM on 6M
I encountered a couple of problems with the K3 and N1MM while on 6M. These problems seem to be resolved by updating to beta version 2.10 of the firmware. In case others encounter them here is a description of the problems. First the mode listed in N1MM's band map would indicate CW-R when the K3 was in CW mode.

[Elecraft] K3 Key-down on power-up
I've got my K3 set up for cw on Field Day with a laptop usb port driving a usb to serial converter. Rig control and cw keying are done over the serial cable, using the K3's built-in ability to send cw from pin 4(?) of the rs-232 cable. Everything works fine, but I got quite a scare when I turned on the K3 and it came up keyed-down 120 watts into no antenna. It seems that if the laptop is not running the logging program, rs-232 pin 4 can very well be in a key-down state. I don't see any way to prevent this event from happening again, except to unplug the rs-232 cable, turn the rig on, make sure vox is off, turn off the K3, plug in the rs-232 cable, and then turn the K3 back on again. Once it happens to you, you get gunshy about turning the rig on with rs-232 connected. Maybe there could be some sort of inhibit to prevent this from happening? Or maybe someone can suggest an easier way to prevent this from happening. On my old TS-850, there was an actual switch to disable vox, and I always disabled vox before turning on the rig. My permanent setup back home uses LPT keying, so I can leave the computer key jack unplugged. Thanks.

Re: [Elecraft] K2 Distorted TX audio on 10m and 12m only
I have a lot of distorted audio problems due to RF getting into my MH2 microphone or the mic cable. It is worse on 12M, 10M, and 6M. The higher the frequency the worse RF pickup problems generally are. If the rig sounds normal when connected to a dummy load (or with power turned down to zero) then it is certainly an RF pickup problem. Don K7FJ My K2 sounds fine on all bands on all modes, both TX and RX except for 10 and 12m. On those two bands, RX is fine, but TX sounds horrible on all modes, LSB, USB, and CW. It puts out full power though. Any ideas? I'd really like to use this at field day. Of course 12 and 10 probably won't even be open...

Re: [Elecraft] [K3] Transmit AM through FM Filter?
Dan, The 'without issue' part is important here. While it could possibly work, to work with spurs and other 'bad things happening' is not likely. The 6kHz filter is for AM transmit. The K3 may even prevent AM transmission if that filter is not installed, but I don't know that for certain. 73, Don W3FPR Dan Atchison wrote: Checked the archives, but unable to find an answer.

There is no indication that the radio is in Test mode, other than the failure to transmit. Actually, there is a (subtle) indication ... the TX icon blinks when in TX TEST mode. I don't think this would help. You'd still have to remember to put it into TEST mode before switching it off. There is perhaps a case for having an option for the radio to come up in TEST mode and stay in that mode until it received a valid command over the RS-232. This could be useful for those who rarely if ever use the radio *without* a computer connected. Even if you don't have a serial port that asserts key down when no logger is active, many PCs do toggle the serial port control lines during the power-on tests at boot-up, causing the rig to transmit a series of dashes. I've had this happen a few times, when I switched on the radio before the computer. Partly because I'm also developing software and prone to accidentally transmitting test messages, I have got into the habit of always switching to TEST whenever I turn on the radio.

Re: [Elecraft] K3 PSK D
Thanks Julian I can also see by http://aintel.bi.ehu.es/psk31theory.html that this PSK-31 waveform is a bit more complicated at keying than simple fsk on/off digital 1's and 0's. You mentioned an interesting aspect of the serial converter that is confusing for me: whether the USB serial ports most people would want to use are capable of working at the nonstandard baud rates such modes would require. Under Windows you would probably have to fight with the system to get access to the serial ports and set these nonstandard UART parameters, making the task much more difficult than it was in 1986 when I wrote my own MS-DOS RTTY terminal program. I purchased an old Belkin usb-serial converter that was recommended as being capable of running at 45.5 baud from the RTTY info web page. http://www.aa5au.com/gettingstarted/rtty_start8.htm Then I discovered that I did not have to use the Tx Data (which I believe is controlled thru the USART), I could have keyed the DTR or RTS control line at 45.5 baud thru the EXT FSK dll. Would not the baud rate of that control pin be controlled by the MMTTY/Ext FSK software, independant of USART standard buad rates? When I used a run of the mill usb-serial converter in the DTR or DTS, it seemed as though it keyed just fine, i.e. I heard the diddle and fsk in the K3 monitor. I am using Xp on a Vostro laptop. I use a serial adapter to tune the K3, and a second adapter to FSK thru an opto isolator. I suspect that all the Mixw type keyers have somehow solved that problem.. I continued this post because I figured it may be of interest to other FSK Rtty folks. Thanks again.

Re: [Elecraft] K3 Key-down on power-up
Dave and folks, That behavior is a natural consequence of an unpowered RS-232 signal line. The voltage on the RTS (or DTR) input to the K3 will be zero or close to it when the computer is not powered. If you check the R-232 signal levels you will find that the region around zero volts (+3v to -3v) is undefined - the system is designed that way to include noise immunity - the RS-232 receiver output might be either ON or OFF when its input is at zero volts - it is not predictable and the real state depends on the behavior of the particular LT1039ACN driver/receiver chip in the K3. Couple that with the fact that the RS-232 'no signal' or 'Space' state must be between +3 and +15 volts to assure an OFF condition at the output of the RS-232 receiver - there is just no way to avoid the 'problem'. As a result, if your K3 is set for PTT-KEY from the RTS or DTR lines, it would be prudent to power the computer on before the K3 so these input signals are at a defined state (hopefully 'space'). Even unplugging the cable will not help because that will also result in zero volts at the input. 73, Don W3FPR Dave Hachadorian wrote: I've got my K3 set up for cw on Field Day with a laptop usb port driving a usb to serial converter.

[Elecraft] [K3] Transmit AM through FM Filter?
As far as I know, the K3 filters are not intelligent, the K3 has no way of knowing what the filter is other than by your setup. If the FM filter was defined as a 5 khz filter, the K3 would probably send the signal through it and the signal would probably be spectrally purer than the vast majority of the gear that's being used on AM today. But the only way to find out would be to put it on a spectrum analyzer. Elecraft has spoken of removing the firmware block at some point in the future. There is also a block that keeps you from transmitting out of band, which is annoying when you're connected to a dummy load. [Elecraft] [K3] Transmit AM through FM Filter?

[Elecraft] [K3] Mic gain with Heil HC elements
I'm just now (finally!) in the process of learning, configuring, and adjusting my new K3 (S/N 888). I have a Heil Pro-Set with the standard dynamic HC-5 mic element, which is known to be kind of low in output compared to most other dynamic mics. It does work beautifully and the audio reports have been excellent -- but to get any ALC bars at all, I have to crank the mic input up to 60 (full scale). This is not a problem, except that there is no wiggle-room. It also makes me worry about there not being enough VOX gain, which I haven't gotten to yet in my setup tasks.

RE: [Elecraft] K3 Firmware 2.10,1.81 problems
I suspect this is an issue of MixW not correctly interpreting the information received from the K3. When in Data modes, the frequency reported by the K3 will vary depending on which data sub mode is in use. Data Default sub-mode sideband Reported frequency FSK D LSB RTTY MARK AFSK A LSB RTTY MARK DATA A USB USB/LSB CARRIER frequency PSK D USB RF frequency (carrier +/- 1 KHz) MixW assumes data modes from the K2 are LSB (there is no separate K3 driver). The firmware error prior to the new beta caused MixW to get the sideband right for Data A by chance. Mix W's K2 setting assumes that the CAT data represents VFO frequency (or carrier) instead of 'MARK' as the K3 reports. If you use FSK D and AFSK A with a standard 2125 Hz Mark, set the Digi Cat correction to -2125. If you are using FSK D, set FSK center fq to 2210 [(2125 + 2295)/2] ... if you are using AFSK A, check AFSK in place of FSK With Data A, Im afraid that the author of MixW will need to create a new K3 driver that assumes USB operation in data modes. Ideally, before then Wayne will have time to implement separate mode get/set commands (on the list) for the digital submodes (FSK D: MD6;/MD9;, AFSK A: MD8;/MDC;, and DATA A: MDA;/MDD;) so MixW (and other digital software) can tell which mode is being used from the IF; response. Then when the authors of MixW (and other software) do K3 specific support they will be able to properly need to do a K3 setting to reflect carrier vs. RF and sideband for each of the digital sub-modes. 73, ...

[Elecraft] [K3] CW feature: Swing?
I got used to this feature on the TS-2000. You can set dash/dot ratio to a number less than or greater than 3.0 (where 3.0 is the default standard -- i.e., the dash is three times the length of the dot). After experimenting, I set mine to 3.7, which gave the transmitted CW a nice little bug-like swing. At first, I thought this was what the K3's CW weight parameter was for, but I immediately discovered that wasn't the case. Would any of you other CW guys out there use such an adjustment in the K3 if it were implemented? I find that's how I naturally want to send, probably a holdover from my bug days years ago.

Re: [Elecraft] K3 for Field Day at 120W
Mark: The K3 is rated at 100 watts so why in the world would you want to mess things up with its spectral purity by running it at a higher power level. Nobody will ever notice a bit of difference in your signal strength between 100 watts or 120 watts. This is like running an engine that is rated at say 4,000 rpm but you want to run at 5,000 rpm. The excellent specs on the K3 are garanteed at the 100 watt level so please don't overdrive it unecessarily to the 120 watt level and give an excellent radio a bad name.

Re: [K3] [Elecraft] Transmit AM through FM Filter?
Of course, the FM filter can be used for AM transmit. All you need to do is tell the radio it is an AM filter. It will not know otherwise. There is really no reason not to transmit wide band AM, just like there is no reason not to transmit wideband SSB. The modes are perfectly legal in most of the world. For voice, it is a waste of spectrum but for digital modes, especially on the higher bands having more audio bandwidth may be useful. I think it might be that, in the USA it is not legal to transmit 15kHz wide AM or SSB. This is a difference between the USA rules and the rules elsewhere. In the USA, people are expected to do foolish things unless they are told not to, hence the limitations on transmitting out of band. Here in Europe, we have just as many fools, but it is considered their responsibility. We suffer greatly because of this but it also gives us a lot of freedom. -- View this message in context: http://www.nabble.com/Transmit-AM-through-FM-Filter--tp18161074p18163177.html Sent from the [K3] mailing list archive at Nabble.com. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K3 Firmware 2.10,1.81 problems Update
As Julian suggested the problem is in MixW. It has been 40 years since I had the RTTY training course in the NAVY, but, it has to do with the convoluted history of RTTY. Although SSB is on the LSB on the HF bands below 30 Meters and USB on those bands above 30 meters (Many reasons given for this most of which are not correct) RTTY was based upon the frequency of Mark (2125) and Space (2295) and the surplus military equipment available, unless you could afford some of the high dollar HAL equipment (which was also used by the military). Military protocol was to have the Mark the lowest tone in frequency. This was ok with most equipment made BPC (Before Personnel Computers). The PC brought out the conversion of telephone modems, use of the modem IC’s and finally the PC sound card for generating these tones. If you built a TNC out of a modem chip and did not include a reverse switch you were stuck to either the low or high bands. This was fixed on the PC with a button to reverse the signal that you could click on and copying. Some of the Rigs treat RTTY as SSB, others put RTTY so that the Mark is always the lowest frequency transmitted regardless of the band selected, and RTTYR reverses this. I have no idea what the protocol is for DATA (perhaps Elecraft can tell us.) As an experiment, try switching rigs in MixW and observe what is happening to the signal frequency. You wil not be able to chang frequency with MixW but you can see what happens to the signal as you turn the dial on the RIG.

HRD hasn't changed here - it's the firmware in the K3 I think. There will soon be an upgrade to HRD which supports new CAT codes currently being developed by the dwarves in the Aptos software mines. Selecting a non-existent filter should not change anything, I've passed this on to Elecraft's software engineers. I'm just back from the Friedrichshafen show and am still drooling - lots of nice radios and big hairy amps, sadly prices exceeding the funds in the 'DRV piggy bank.

RE: [Elecraft] K3 Firmware 2.10,1.81 problems Update
RTTY was based upon the frequency of Mark (2125) and Space (2295) and the surplus military equipment available, unless you could afford some of the high dollar HAL equipment (which was also used by the military). No, RTTY is always Shift low - that is Mark is the HIGHER RF frequency and space is the LOWER RF frequency. When the audio tones 2215 and 2295 are applied to a LSB transmitter in AFSK this results in the correct shift. I have no idea what the protocol is for DATA (perhaps Elecraft can tell us.) As an experiment, try switching rigs in MixW and observe what is happening to the signal frequency.

[Elecraft] K3 Update on Firmware
About 3 weeks ago I posted a problem with my K3 failing during a firmware update. I finally got around to finding the problem (yes I'm sloo) It turned out to be a faulty USB to Serial Cable.Today I picked up a Radio Shack 6 ft USB-A to Serial Cable (part number 26-949). This cable mates to the K3 connector (It has the screws ,not nuts) as I was ask by Dick,K6KR to watch for this. So now my K3 is working again!! I would like to think Dick Dievendorff K6KR for his prompt help and the many many email he sent me to find the problem.

RE: [K3] [Elecraft] Transmit AM through FM Filter?
We on this reflector have often beat to death the American FCC Amateur service rules about bandwidth since they give no numbers about what is acceptable as long as the emission stays within the Amateur band. Unlike commercial frequencies, where specific technical standards avoid co-channel interference with other services, the rules for Amateur emissions are vague in keeping with the basic philosophy about not having rules where no rules are required. From a technical standpoint, the signal-to-noise ratio drops as the bandwidth increases. The best signal to noise ratio for a given effective radiated power is found at the narrowest bandwidths. That's why CW works with signals that can't be heard at all on SSB, and why SSB gets clear copy with signals unreadable on AM. Even if the receiver filter is tailored to match the signal, the amount of noise power increases in direct proportion to the bandwidth. The effect upon the listener is that the noise gets louder and the signal weaker as the bandwidth is increased. So, without trying to argue the law, that is a solid technical reason to maintain narrower bandwidths whenever possible. In free society, such as the USA, begins with the concept that citizens can do *anything* that pleases them but, to avoid injury to others, we must adopt laws prohibiting specific behavior. The objective is to have as few laws as possible, and to write the laws to prohibit exactly the behavior that is damaging. Of course we Yanks didn't invent the concept. One predecessor was the Magna Carta. Sure, some Americans don't understand that or they choose to freeload, taking advantage of anything they can get away with without respect to the law. That injures the rest of us, then we're further put out by having to pay to keep them locked up when they are caught. But the vast majority of Americans I've known over my lifetime are what we call honest, law-abiding citizens, in spite of what the movies suggest. Indeed, like all good story tellers, novels and movies dwell on the unexpected and unusual, not the commonplace. Ron AC7AC -Original Message- Of course, the FM filter can be used for AM transmit. All you need to do is tell the radio it is an AM filter. It will not know otherwise. There is really no reason not to transmit wide band AM, just like there is no reason not to transmit wideband SSB. The modes are perfectly legal in most of the world. For voice, it is a waste of spectrum but for digital modes, especially on the higher bands having more audio bandwidth may be useful. I think it might be that, in the USA it is not legal to transmit 15kHz wide AM or SSB. This is a difference between the USA rules and the rules elsewhere. In the USA, people are expected to do foolish things unless they are told not to, hence the limitations on transmitting out of band. Here in Europe, we have just as many fools, but it is considered their responsibility. We suffer greatly because of this but it also gives us a lot of freedom. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K3 PSK D
wb7ond wrote: Thanks Julian I can also see by http://aintel.bi.ehu.es/psk31theory.html that this PSK-31 waveform is a bit more complicated at keying than simple fsk on/off digital 1's and 0's. You mentioned an interesting aspect of the serial converter that is confusing for me: whether the USB serial ports most people would want to use are capable of working at the nonstandard baud rates such modes would require. Under Windows you would probably have to fight with the system to get access to the serial ports and set these nonstandard UART parameters, making the task much more difficult than it was in 1986 when I wrote my own MS-DOS RTTY terminal program. I purchased an old Belkin usb-serial converter that was recommended as being capable of running at 45.5 baud from the RTTY info web page. http://www.aa5au.com/gettingstarted/rtty_start8.htm Then I discovered that I did not have to use the Tx Data (which I believe is controlled thru the USART), I could have keyed the DTR or RTS control line at 45.5 baud thru the EXT FSK dll. Would not the baud rate of that control pin be controlled by the MMTTY/Ext FSK software, independant of USART standard buad rates? When I used a run of the mill usb-serial converter in the DTR or DTS, it seemed as though it keyed just fine, i.e. I heard the diddle and fsk in the K3 monitor. I am using Xp on a Vostro laptop. I use a serial adapter to tune the K3, and a second adapter to FSK thru an opto isolator. I suspect that all the Mixw type keyers have somehow solved that problem.. I continued this post because I figured it may be of interest to other FSK Rtty folks. Yep, that is interesting. I had my doubts about the USB to serial converters because I haven't even managed to get one to work yet with normal serial communications. (Fortunately my shack PC has a real serial port and I'm not planning on replacing it with a laptop anytime soon.) I did wonder whether you could press one of the other unused lines into service to send the data, but assumed that it might be rather tricky getting the right timing. However, obviously someone clever has already done that. Still, I'm hoping that the KY command protocol will soon be fully functional, which will achieve the same result without any extra wires or DLLs. I'm particularly interested in being able to use it for PSK31, since my KK7UQ IMD meter tells me that my IMD is 2dB better using the internally generated modulation than it is using the soundcard. - Julian, G4ILO K3 s/n: 222 K2 s/n: 392 G4ILO's Shack: www.g4ilo.com KComm for K2/K3: www.g4ilo.com/kcomm.html -- View this message in context: http://www.nabble.com/K3-PSK-D-tp18153773p18165323.html Sent from the Elecraft mailing list archive at Nabble.com. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] [K3] CW feature: Swing?
Ron, I have paralleled both an N3ZN and Begali signature to key my K2's. I bit expensive for keying SSB transmit, but I think very impressive if not overkill. Can't wait to do the same for the K3 on the order list. Maybe I'll use just one. And move the only the Begali to the K3?! A bit obsessive, except that I actually operate C.W. here and there. :-) 72, Bill K9YEQ K2 #35, K2 # 5279, KX1 #35, Mini Modules, etc. -Original Message- I just use my Bug to key the rig! ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K3 - Sensitivity drop between Low and Hi power
max iw0gxy wrote: Hi all, I connected the XG2 signal generator to my K3 and I've injected 50microV into the antenna. I have the standard S9 but when I rise the power to 13 and up signal drop down to S8. If I turn the knob to 12W or less signal turn back to S9. I've noted this behavior on signals on air but to be sure I've used my signal generator. I do not see any change in received signal levels here when switching between low and high power. -- 73, Vic, K2VCO Fresno CA http://www.qsl.net/k2vco ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] K3 - Text Decode
Still learning my K3. CW Text Decode works flawlessly on W1AW bulletins and code practice [OK, visual decode on code practice is sort of oxymoronic]. Quality of decode seems to be very sensitive to the THR setting, but when you get it right, it is nearly perfect. Not so perfect on real hams, but not bad. Unfortunately, except for record traffic which I rarely do anymore, it is distracting to copying in my head, so I won't be using that feature much. Couldn't find any RTTY stations on to test AFSK. PSK31 was very good, once the old ham read the manual. Haven't tried the CW to Data mode yet, I'm sure it works, just one thing at a time. Firmware 2.10 has made a huge improvement in NR. Not sure if it was supposed to change NB, but that's better too. This is a cool radio! 73, Fred K6DGW - Northern California Contest Club - CU in the 2008 Cal QSO Party 4-5 Oct 08 - www.cqp.org ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] SSBCW VFO offset
This is something I thought already behaved the way I want it to, but it doesn't seem to. I've read through the manual, so if I'm missing something, somebody please tell me. If I'm copying a 6m CW signal in USB mode and switch the K3 to CW(REV) mode (which corresponds to USB), I want to see the VFO change frequency in the right direction (up, in this instance, or down when switching from CW(REV) to USB)) by the amount of the PITCH frequency. It doesn't. This means when switching from CW to SSB or back, I lose sync with the CW signal I was copying. We want to be able to stay in pitch-sync with a CW signal while switching back and forth between SSB and CW modes. If there is a setting that already sets the K3 up with this behavior, I'd like to know what it is. Otherwise, could we please have an implementation of this at the earliest opportunity? The CW-in-SSB mode behavior works great, and I love it! But we also need this VFO-offset behavior when switching between these modes as well. It should be an option you can set in Config -- Auto offset VFO CW/SSB or something like that. In the Kenwood TS-2000, it's called Frequency correction for SSB-to-CW change (ON/OFF). We VHF ops would be very grateful. Thanks, Bill W5WVO ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.
