This is a simple user configuration issue with Writelog. MMTTY always produces DUAL CHANNEL MONO output. However, you have told Writelog you have a stereo soundcard and assigned RTTYrite to "radio right." WriteLog is panning the output audio (actually turning down the left channel in the soundcard mixer) to send the AFSK audio to the channel you selected. Check the Writelog help files - there are at least three ways to fix your problem: configure your soundcard as a mono soundcard, assign RTTYrite (the RTTY window) to the left radio, or tell WriteLog your only radio is "radio left." Even if you have set-up Writelog for a single radio you must still tell WriteLog that the radio is radio left" if you are using a stereo soundboard. You may also be able to use the WriteLog Soundboard control application to disable Writelog's control over the soundcard mixer. 73, ...

[Elecraft] K3 Audio I/O & WriteLog/RTTYrite/MMTTY
A cautionary tale I am a long time user of MMTTY and DM780 for audio digital modes on my K3. In getting ready for FD I set up RTTYrite with MMTTY for the first time in WriteLog. When I went to test the output I found that the K3 went into transmit mode but no signal was generated. Pulling the audio jack out at the computer produced the expected squeals from the laptop. After rechecking all settings I wiggled the audio line in plug to the K3 and was able to get some signal. After repeated tries over several days with the same results I concluded that the jack on my "old" (#70) K3 was loose and I ordered a new audio I/O board. After replacement I had the same problem! I eventually discovered that there was no signal coming out of the left channel of the laptop, which is the only channel the K3 responds to. Wiggling the plug apparently caused the right channel portion of the plug to contact the left channel jack. On a tip from a friend I checked RTTYrite/MMTTY. Sure enough, even though I set the balance in the center with the toolbar app, when I fired up Writelog/RTTYrite/MMTTY it would reset the balance to the right channel only. It also locks the toolbar app out from changing the balance back. MMTTY stand alone does not play this nasty trick. I have observed it only when used in WriteLog/RTTYrite.

[Elecraft] K3 Channel Hopping & Memory questions
When the 6 Meter band is dead, I like to either scan a range of frequencies or channel hop with my K3. Channel hopping is preferred because 10 specific frequencies can be monitored without the scan stopping on unstable (frequency or amplitude) signals from nearby electronic devices. I usually set up for channel hopping ten discrete CW and SSB frequencies on either side of 50.100 MHz. After setting up the bank of 10 memory channels and flagging each with an asterisk, when I press the M>V button and turn the VFO-A dial, I can manually scan each memory channel. As expected, the mode stored (CW or SSB) is the one I hear when the VFO-A knob is turned. But when I start the automatic channel hopping, the mode does not change. The mode used in the hopping appears to be mode that was in effect when the scan button is pressed. Can the firmware be modified so the mode stored with each memory position is the one that is used when channel hopping? On another memory related matter, it appears that the filter bandwidth chosen for the last stored CW memory is the bandwidth applied to every CW memory in the bank of 100 memories. The same holds for the last filter chosen for a SSB memory. Are there plans to also store the preferred bandwidth AND mode chosen for each stored memory channel? Thanks to all on the Elecraft team who continue to improve the functionality of this great K3 radio. 73, Rich - K1HTV __ 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

To set them most effectively, set the TXEQ for your mic and voice FIRST, with no compression and enough gain to get some ALC indication. In general, you want to turn down the bass (the lower bands) so that you're not wasting power on breath pops and the parts of your voice that don't contribute to intelligibility. Have a good listener tune you in with a wide IF bandwidth, and tell you when you have it right. THEN do a final setting for the mic gain, and dial in some Compression. For competitive audio, keep compression between 6 and 10dB on peaks.

At one point the ham next to me running cw while I ran SSB (both of us xmitting a lot), saw me run my hand over the top of the K3-he did the same to his and we took off our headphones and remarked at the same time "it's running extremely cool." There was relatively cool air coming out at the exhaust point. We also noticed no cross interference form on e another even though we were 3-4 feet apart.

Re: [Elecraft] power pole pins
PowerPoles have huge advocates and huge objectors. They are very convenient for setups that are frequently changed, since connecting is simple, safe and easy and the metal contacts are shielded making an accidental short less likely. A HAM friend of mine with 40 years experience in high end aircraft electronics does not like them because there is no positive locking mechanism to keep the connectors together. Many are concerned about the metal pins designed to hold two poles together. They can sometimes come loose from the connection. IF this happens you have a piece of metal floating around that could cause a short circuit. That is why many of us don't use the pins. __ 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] my K3 F/D experience
My "FD" experience was a bit different. I operated some with my K3/10 "1D" from the home QTH with the old dipoles up on 75/40/20m. I wanted to play SSB QRP and see what kind of fun I could have. I used HamRadio Deluxe, PSDR for interface then spotted and pounced. I only ran for a couple 2 or 3 hrs and very casually. I had about an equal number of QSOs on 20 and 40 with just a handful on 75, since the operations were mostly mid afternoon Saturday. It seemed that the 20m QSOs were easier than 40m, with seems counter intuitive. I use a Softrock on the IF to drive PSDR and I chose mostly the stronger stations to pounce on, but not all, by any means. One really neat 75m QSO was working W0CIA who was running an 817 at 3w from the top of a fire tower somewhere here in northern MN. Lots of positive comments on the good signal for the 10-12watts. I ran with the Elecraft hand mike and the compression set at 16. I only recently started using compression at all, and it makes a very big difference. Been hamming 55yrs and never used compression on any of my previous gear. Old dogs can learn new tricks. The local club had a Field Day station I visited over the weekend, I ran a bit of 40m with a Kenwood 450. Very smooth little rig to operate, but it seemed I had to call more than at home QRP. Lots more adjacent frequency QRM and I sure missed the Softrock panadapter. My K3/10 spends most of its life as my 6m - 10Ghz IF rig.

Re: [Elecraft] my K3 F/D experience
Yep, it's already there (although not settable from the K3 Utility). From the FW release notes: "MCU 3.19 / DSP 2.17, 6-14-2009 * POWER-RELATED CONTROL LOCK: The PWR, MIC, and CMP controls can be locked by tapping '1' in CONFIG:PWR_SET. This is useful in some contests, such as Field Day, where a carefully-set up K3 might be used by multiple operators. Accessing a locked control flashes "LOCKED". SPD/DELAY/MON functions are still accessible. Tapping a locked knob still displays the current parameter value, even though you can't change it." (Of course, there's nothing to stop an op who knows the "secret" from simply unlocking the controls.) 73 -- Joe KB8AP On Jun 29, 2010, at 6:25 AM, Paul Christensen wrote: > ... > Probably not too SSB-neighborly that way.

[Elecraft] power pole pins
The pins used to hold power poles together are not unique - these types of pins have many applications and are standard items at most any well equipped hardware stores.

Not sure if this is already implemented, but I could almost see a need for maximum PWR and Tx compression settings, controlled only through the K3 utility software where those parameters could be set to some temporary maximum value -- say 100W for stand-alone K3s and ...~35W for use with amps on contest weekends where the K3 may be shared among several button-happy operators. Locking down those parameters and making them only adjustable through utility software might be enough keep guest ops from experimenting with controls that can do the most harm on the bands.

[Elecraft] my K3 F/D experience
I took my K3 to our club's Field Day operation. We have some serious contesters and DXers in the group, most of which are Yaecomwood owners. A couple have TenTec. Most of these guys have 5 band DXCC or are Honor Roll, etc. We can operate CW and SSB on the same band simultaneously and often do. Band conditions here in the NE were not very good. My K3 has the Heil Proset for head phones and boom mike. I thought you all might like to read my observations: The first operator wanted me to set the receive equalizer flat, change the filter settings, etc to make the rig more suseptable to noise, QRM, etc because he said that without all the hash, intermod, etc, the bands sounded dead. He wanted the K3 to sound like what he was used to. While he might have been happy with the new settings when I listened to it, it was tiring...meanwhile that guy barely gave up the use of the K3 for the entire weekend! His arguement was that without hearing a bunch of noise he couldn't tell if the spot he picked to run stations was quiet or was being QRMed by adjacent signals. Interesting. Two other CW ops sat down for a while, running 35+WPM and were very impressed with the smoothness of the rig. They both liked the filtering and the strength of the front end in the presence of other strong signals. EVERYONE cranked the RF gain to the max, even when I showed them that if they ran it about 2-3 O'clock and adjusted the audio gain instead they would have a more pleasant audio to listen to. Oh well, bad habits die hard. One comment I got was that this was the smoothest VOX of any rig the guy had operated. One problem we had was that the guys couldn't get the Ant 1 and Ant 2, and the several coax connectors straight in their minds. So occasionally after switching a coax I had to go over and see why there was no output. It was always operator error. The transmitting into no load did not cause any problems with the K3. Just the first time, I paniced because I thought that the finals had blown 2 hours into the operation. Fortunately it only took a few seconds to see what happened when someone mentioned they changed antennas. I did get a comment on the ease of figuring out the menu options as they were more intuitive than the operator was used to. Comments on the small size compared to the other rigs we had. Only one negative comment was the buttons are close together. We use band pass filters in the coax because of the 2 stations per band, but did not need those in line for the K3. Also, while I could hear some interference when I sat down behind a Kenwood 930 from another station, I never heard the K3. Every operator cranked the K3 output to max (110W output) could not get them to leave it at 100. But there were no problems observed. Every op had to fiddle with all the buttonsthat's to be expected. Hey, we're hams. For the entire 24 hour period, I barely got to use my own rig. At one point there was a waiting list to sit down behind the mic or key. When I got home, it took a bit to get things back to normal for me because I had to figure out what everyone did. Of course I reloaded my configuration which speeded up that process. Bottom line: The rig performed flawlessly. Even with pretty hard use, everything went well. Thanks for a great product!

Re: [Elecraft] K3: FD 2010
We used 3 K3's at our (Midland, Tx ARC) field day set up. Had the same results that Brian spoke of. I was impressed by the receover perfprmance and the ease of operation. And Brian's a;so right about the onslaught of orders-I'm putting mine together now. Wow what a concept and what a rig.

There was significant resistance to using tribanders placed in a line 150 ft and 75 ft apart, because the former monoband antennas themselves were supposed to provide significant isolation, but even the skeptics were convinced.

Re: [Elecraft] Weird K3 Problem
Many thanks to those of you who commented on my K3 problem, which was that the front panel button functions were "scrambled." You've all correctly identified the problem as being a stuck pushbutton on one of the rotary encoders. The front panel buttons tap onto a voltage divider chain, whose voltage is read by an A to D convertor that tells the microprocessor which button is pressed. If one button is stuck, it messes up all the buttons because the divider chain for the other buttons is then wrong. (In effect, each button is then sitting on a wrong rung of the ladder). In my case, repeatedly pushing the errant button caused it to start working again, at least temporarily. If the problem recurs, which I suspect is likely, I'll have to send the front panel back to Elecraft, since I'm told swapping the encoder is not an easy job. Dale at Elecraft told me this problem tends to occur with encoders that aren't used frequently. That was my situation, since the problem encoder controlled the CW keyer speed and I use an external keyer. 73, Jim W8ZR __ 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] Anderson Power Poles?
Do you have a pre-made cable? Mine snaps securely onto the K3 connector, fits snugly and has never fallen out. At the time I bought my K3 there was a big discussion here about how to assemble these plugs, so I decided to just skip all the fun and order a pre-made cable. Anyhow, if there's one thing I hate when buying some new piece of gear it is having to solder plugs. It is strictly plug-n-play for me; not play with the plugs. One thing I like about the APP's is they seem very durable. I frequently plug and unplug the power cable (and all the other cables on my K3) during t/storm season. They fit as well as the first time they were used. Convenient also-- don't even have to look at the back panel; just reach back and yank the cord out or snap it in. 73, Drew AF2Z On Mon, 28 Jun 2010 09:03:31 -0400 (EDT), jim ab3cv wrote: >After watching the PP connectors on my K3 wiggle around at Field Day, I >have to question again why Elecraft chose these toads-in-a-tuxedo for a >connector.

On the amplifier 15pin plug, I use pins 1, 9& 14, yes it's that simple. On the K3 RS232 I connect the amplifier pin 1 to K3 pin 3 (I think, I may have these two crossed) On the K3 RS232 I connect the amplifier pin 9 to K3 pin 2 (I think, I may have these two crossed) And On the K3 RS232 I connect the amplifier pin 9 to K3 pin 5 as ground Within the K3 RS232 I need to link the RST and CTS together, well RTS is pin 7 on the K3, but what pin is the CTS??
[Elecraft] K3 microphone input noise
Hi, My K3 last arrived last week and I have been getting to grips with it. However, I think I may have an issue with noise in the mic amp /adc. The headset I hoped to use is one that I have successfully used with my FT1000MP, a Sennheiser HMD25-1. This has a 200 ohm dynamic mic insert. With the K3 I find that I need to use the high gain setting and a relatively high mic gain level (30 -40) to get anywhere near the required 4-5 bars of ALC. With that much gain I hear more noise than I would expect to. The noise is mostly white but has a distinct whine which I estimate to be at around 1500Hz. The situation is the same using the front or rear mic sockets. I have also tried a number of other headsets. A Bayer DT190 with a 200 ohm dynamic mic insert gives similar results to the HMD25-1. A Sennheiser HME25-1 which has an electret mic insert is a little better (probably because it has a higher output level) although still requires fairly high gain. The best results so far have been with a low cost computer headset or a £1.00 electret mic capsule. With both of these I was able to use the low gain setting and a mic gain less than 20. So, some questions... What sort of gain level should I expect to use for a dynamic mic? Are other K3 mic amps as noisy as the one I have, if not then where should I start looking for the noise issues? Does anyone else hear the tone in the noise with the mic gain turned up? 73 Ian. __ 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] Help with ideal SSB contest settings
With Rob, Don't be scared to crank up the mic gain and compression setting, Only if you set them to the extremes you will cause trouble on the bands, especially when you use an amplifier. Have fun!

The KIO2 works at a fixed baud rate of 4800bps and some of the adapters that work OK at higher speeds will garble the data at that speed. I would also emphasize the advice that you *must* use a properly wired (as per the KIO2 manual) cable between the loose end of the adapter and the K2. - Julian, G4ILO.
