[Elecraft] Felt washer source?
I know this was discussed WAY back when in the earlier days of the K3. I need a felt washer, the type that sits between the vfo tuning knob and the front panel. Can anyone suggest a local source?

You can get felt washers at Walmart. Go to the automotive batteries. I don't know if the hole would be too big or not, but you can try it and see. 73, Joel - W4JBB On 4/14/13 8:42 AM, Barry N1EU wrote: I know this was discussed WAY back when in the earlier days of the K3.

Re: [Elecraft] Felt washer source?
Make sure that these washers are not chemically treated. I think some are. This is done to neutralize battery corrosion.

[Elecraft] Elecraft KX3 Internal NiMH Power Supply Voltage after Charge
Hello group: Last night I installed new NiMH batteries (the Powerex 2700 MaH variety) into my week old KX3 for the first time and set them for a 12 hour charge. After the charge was complete, the KX3 PS display indicates a power supply voltage of only 10.8 volts, which drops to well below 10.0 volts on transmit. I'm sure that this is lower than it should be. I haven't re-opened the case to check for bad or ill-fitting cells yet as it is a little bit of a tricky open. So I guess the questions are these. 1) What voltage have other group members experienced with the internal NiMH PS after charge? 2) What charge duration are other folks using?

After the charge was complete, the KX3 PS display indicates a power supply voltage of only 10.8 volts, which drops to well below 10.0 volts on transmit. Those are not the low-discharge variety, so are likely totally discharged on arrival. 2700/200 is 13.5h, and you need to charge more than rated capacity because charging is not 100% efficient. So for 2700, 16h is definitely warranted, and I might recommend 18h on first charge, but you can't set that. I'd give it another 4h, maybe 6h (humuan in the loop timing control from 8h :-). Undercharging is scary because it can lead to cell imbalance and you really don't want to reverse bias NiMH batteries. 10.8V/8cells is 1.35 V/cell. For a NiMH under any load, that's very much charged. 10.0V is 1.25 V/cell. At rest, that indicates a discharged cell, but under any significant load there is no problem. Set your BAT MIN to lower; probably 8.4V makes sense (1.05 V/cell, which you may well see under transmit loads), or even 8.2V. When doing test discharges on NiMH cells, I use 200 mA and discharge to 0.9V, using a MAHA C9000. That corresponds to 7.2V for 8 cells. I recommend getting one of those chargers and measuring your cell's capacities before putting them into service and then yearly or if they seem to be acting up. I have been happy with the powerex/maha batteries, but have found that the regular (non-Imedion) ones self discharge quite rapidly. 73 de n1dam __ 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] Elecraft KX3 Internal NiMH Power Supply Voltage after Charge
Steve I have several sets of batteries for my KX3 and I have 2 sets like yours. I have found from experience the first time they (or any) need to be conditioned in an outboard charger/conditioner it takes a full 14 hrs. to cycle the charge discharge. Then they go into my KX3 full power and the charger takes care of them just fine on a 12 hr. charge most of the time. After 10 charge/discharge cycles I remove them from the radio and recondition them again so they can be brought back up to where they can hold a full charge. 73, Fred/N0AZZ K3 Ser #'s 6730/5299--KX3 # 2573--K2/100--KAT100 P3/SVGA--KPA500--KAT500--W2 -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Steven C Veal Sent: Sunday, April 14, 2013 9:40 AM To: elecraft@mailman.qth.net Subject: [Elecraft] Elecraft KX3 Internal NiMH Power Supply Voltage after Charge Hello group: Last night I installed new NiMH batteries (the Powerex 2700 MaH variety) into my week old KX3 for the first time and set them for a 12 hour charge.

Re: [Elecraft] Felt washer source?
I think all of those battery washers are heavily chemically treated and I don't think I'd want one anywhere near my rig. Home Depot carries a wide assortment of felt circles for use under table legs or as bumpers for cabinet doors, etc. They have adhesive on one side (which could face the knob), but if you don't like that the felt is thick enough that you can actually shave off the adhesive with a sharp razor. 73, Dave AB7E On 4/14/2013 7:37 AM, Rick Dettinger wrote: Make sure that these washers are not chemically treated.

Re: [Elecraft] K2 + SignalLink: Setting gains for digital modes
Can't help you with the specific problem as I use a RigBlaster instead of the SignaLink. But a means to monitor your signal quality is pretty basic and the solution is simple. I have both the PSKMeter (~$45 kit) and the KK7UQ IMD Meter (~$150 assembled). Both do a great job. Both can be online at all times to monitor PSK31 and PSK63. I find that IMD levels change using the K2 depending on band to some extent and things get bumped, so I don't like to just set-and-forget. Both meters agree fairly closely when I've used them simultaneously. The PSKMeter requires inserting a BNC T-connector at the output of the K2. This is used to couple a sample of the outgoing rf signal to the meter. The meter connects to a serial port on your computer for display of results. http://www.ssiserver.com/info/pskmeter/ The IMD Meter is self sufficient. No connections to the rig or computer; a small antenna picks up your transmitted signal. Results read out on a small LED display. It doubles as a field strength meter. With no connections, it's always ready for whichever rig I fire up (K2, PSK-20, Softrock Xcvr) http://kk7uq.com/html/imdmeter.html There are probably other easy ways available, but I think it should be basic equipment in a PSK shack.

Re: [Elecraft] K2 + SignalLink: Setting gains for digital modes
Chris, what mode are you trying and what do you have your power set to? Also if your RX and TX on the Signalink are maxed, use the Signalink internal jumper to boast the gain so you can turn them down. Also check the computer volume both sound and microphone recording. And make sure the computer is recognising the Signalink as a USB audio codec .

Re: [Elecraft] K2 + SignalLink: Setting gains for digital modes
Chris, For data modes with the K2, there is an indication in the K2 itself that should prevent splattering. That is the ALC meter. Turn the RF/ALC meter to read ALC, then adjust your audio level until you see the LED display blinking the 10th bar of the LED indicator - then back off the gain a bit until that 10th LED flickering goes away. At that point, your audio level is correct. Now adjust the power knob to your desired power output level and operate. I do suggest that you set up the RTTY filter set and use those filters for data modes because the SSBC menu item is independent of the SSB setting. Set SSBCr to 1:1 (the SSBC parameter for SSB can be set to anything desired for voice). That will assure that you have compression turned off for data modes. 73, Don W3FPR On 4/14/2013 12:25 PM, Chris Kimball wrote: I operate digital modes with the K2/KPA with a SignalLink computer interface.

Re: [Elecraft] [P3SVGA] Missing Fn key display on P3 after installing P3SVGA
Hi Bob, A dyslexic typo on my part. Jim is W4ATK.

They are accessed as F1 thru F12 (CW), SHIFT F1 thru SHIFT F12 (PSK31), ALT F1 thru ALT F12 (RTTY), and the aux group, CTRL F1 thru CTRL F12.

Re: [Elecraft] K2 + SignalLink: Setting gains for digital modes
Chris, With your soundcard gains at maximum, it is possible that the output is being overdriven and causing distortion (they are not out of the picture at all.

Re: [Elecraft] Mobile Experiences
Hi Tom, You might want to take a look at the KX3 Mobile User Guide, posted on Elecraft's web site: http://www.elecraft.com/K2_Manual_Download_Page.htm#kx3_mobile I'm also a MARS op, and have used the KX3 mobile for MARS ops. The only issue I've found is making sure that the antenna is resonant. Standard-cut ham band resonators need mods sometimes, but if you're working with one of the screwdriver types of mobile antennas this is not a problem. With the shorter length antennas (Hustler in my case), the 100W amp is borderline mandatory, though I have worked a number of nets and events from the mobile without the amp: SSB, MT63, Thor, etc. Note also that I'm updating the Mobile User Guide. There will be some major structural and content refinements on the next go-around. Since I've decided to redo my mobile, I'll be document that development as it moves along. If you're interested, I accept docs for inclusion in the mobile guide and give credits. So far no one's taken me up on this. :) 73, matt W6NIA / NNN0UET On Sun, 14 Apr 2013 14:10:09 -0500, you wrote: Hello all, I'm thinking about purchasing a KX3 for mobile use, and will eventually want to use it for MARS mobile use with the 100W amp from Elecraft.

Several times I've published a simple procedure for setting computer sound card levels. It goes like this. 1) Find cliip level on the sound card. To do this, feed the sound card output to a scope, get your RTTY or PSK program going, and push the buttons that cause it to send tones to the radio. On the scope, gradually increase the sound card output slider until you see squaring at the top and bottom of the sine wave. If you don't have a scope handy, listen on headphones as you gradually increase the level until you hear the tones get raspy or harsh or brighter. With an AC voltmeter, look for the point when the reading no longer increases as you increase the slider. Of these three methods, the scope is best, your ears and headphones are second best. Use the voltmeter method only if your hearing is gone and you don't have a scope. 2) Now that you've established clip level, back off the slider by 6 -10 dB. 6 dB is half the voltage, 10 dB is about one-third the voltage, easy to see on a scope or voltmeter. If you're using your ears, back off the slider until it SOUNDS half as loud. This works because human hearing is logarithmic, and a reduction in level is HEARD as half as loud. The reason we go 6-10 dB below clip is that distortion in cheap audio stages starts rising in the range of 6 dB below clip, so we make our signals cleaner if we back it off by that 6-10 dB. . This procedure works for ALL audio output stages and all radios, and is not limited to Signal Link (which, by the way, is not that great a sound card). This procedure sets the level for the computer output. You still need to follow instructions in the K3 (or KX3) manual to set levels in the radio itself. 73, Jim Brown K9YC __ 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] K2 + SignalLink: Setting gains for digital modes
Yes, the K2 transmit gain can change with the various bands. There is some level of TX RF gain compensation in the K2 circuits, but it is not perfect. Because of the way the K2 controls power, setting the power first and then bringing up the audio to produce that power output is a bit iffy. Adjusting the audio for no ALC indication as I stated earlier and then adjusting the power knob will always work. Explanation -- The K2 tries to adjust the power output to produce the requested power in all cases. If the audio input is too low, the K2 measures the RF power output, then compares it to the requested power - the MCU will increase the power in an attempt to bring up the output power - your audio will still be low at that point, the K2 will increase the drive, and then when you subsequently increase the audio level, the power will overshoot the requested power, and then has to do the process over again to bring the power down. The result is that there are often complaints about power creep when using digital modes. For best results, adjust the audio level first for full audio but no ALC, then adjust the power knob. 73, Don W3FPR On 4/14/2013 3:23 PM, Bill Coleman wrote: On Apr 14, 2013, at 12:25 PM, Chris Kimball m...@cvkimball.com wrote: I operate digital modes with the K2/KPA with a SignalLink computer interface.

Unfortunately I lack instrumentation to study the problem. You have to adjust the gain as you change bands. Unfortunately the K2 gain profile varies wildly from band to band. Either adjust until you just barely get any ALC indication, or adjust until you just barely get the requested power out. How should I set the audio (SignalLink) drive gain and the RF (K2 Power) drive? My normal operation is not smoke-producing, so this is not a duty-cycle question. Set the K2 power level at whatever power you desire. Then increase the audio level until you just barely make that power level. You should be pretty close to just barely having ALC action. When you change bands, do it again. __ 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] K2 + SignalLink: Setting gains for digital modes
Another minor issue is that the audio drive will vary somewhat depending on which audio frequency is selected. i.e. 600 hertz vs 1800 Hz. will not exhibit the same energy to the radio. Soundcards are not flat, many rigs are not either. So if you set levels for one (if RTTY, pair of) frequency, you can over/under drive the rig. Under is better than over, at least you don't produce the dreaded IMD complaints but you may miss the contact too. ;-) 73, Rick wa6nhc Tiny iPhone 5 keypad, typos are inevitable On Apr 14, 2013, at 1:33 PM, Don Wilhelm w3...@embarqmail.com wrote: Yes, the K2 transmit gain can change with the various bands.

Re: [Elecraft] K2 + SignalLink: Setting gains for digital modes
I've been playing with this for the the last few hours. It's possible to reduce the input level to get the 10-th ALC bar to disappear and, apparently, provide too little signal to the RF amp. It seems a little sensitive on the SignalLink Tx gain control. Given that I'm at the low end of the gain for a single ALC bar indication, am I likely to be overloading? In other words, is a single ALC bar acceptable if it's at the low end of the Tx gain setting? I am going to 50% gain on both sound card levels.

Re: [Elecraft] Elecraft KX3 Internal NiMH Power Supply Voltage after Charge
Acutally NiMH cells have a Coulometric Efficiency of 66%, which means you need put 1/0.66 = 1.51 (or 151%) of the charge back into the battery.(assuming it is fully discharged). If your target cell were 2700 mAH, and it was dead, then you need to put 2700/0.66 = 4090 mAH.

Re: [Elecraft] P3 lvl cal?
Tom, There are several reasons why the signal level can be different on the P3 and K3, as explained in the How to Set Up and Interpret the P3 Display section of the P3 Owner's Manual. The main reason is that the effective bandwidth of the P3 is narrower than the K3, so more of the signal gets through to the K3 S meter than a single pixel on the P3 display. For that reason, the signal or noise level on the P3 can appear quite a bit lower than on the K3 S meter.

Re: [Elecraft] P3 lvl cal?
Hi Matt, If they matched it would be a coincidence. For example, if the P3 is set to 45 kHz span, then each frequency point on the P3 display is about 100 Hz wide. If the K3 bandwidth is 2.7 kHz, then on a wideband signal like band noise or SSB, 27 times (14 dB) as much signal is getting to the K3's S meter as gets to each frequency point of the P3. So you'd expect the average signal level on the P3 to be about 14 dB (2 or 3 S-units) lower. To illustrate this without a P3, try this: Set the K3 to the normal 2.7 kHz bandwidth, tune in an SSB signal and note the S meter reading. Now change the K3 bandwidth to 100 Hz and note the S meter reading. It will be much lower.

I wonder if the software guru's have considered or are working on a way to save the keyboard load to a thumb drive the way we can currently save an image? Seems like that would be a great option if possible. Rick On 4/14/2013, at 11:32 , Wright, Robert rwri...@ap.com wrote: Hi Bob, A dyslexic typo on my part. Jim is W4ATK. The post is here: http://elecraft.365791.n2.nabble.com/P3SVGA-data-RTTY-FSK-D-tp7560370p7560415.html Here is the crux of it: I have divided the 50 Text message capability into 4 groups CW (12) PSK31(12) RTTY (12) and an auxiliary group of 12. They are accessed as F1 thru F12 (CW), SHIFT F1 thru SHIFT F12 (PSK31), ALT F1 thru ALT F12 (RTTY), and the aux group, CTRL F1 thru CTRL F12. Each function key carries basically the same message, just personalized for the particular mode, so other than remembering the correct pre-key, F! is always CQ. etc. For the contest I used the aux group, ALT Function Keyes personalized for the Grid Dip. I'm also interested in other's creative uses for keyboard macros for the P3SVGA. For instance, I read somewhere that when Elecraft was demoing the P3SVGA at a tradeshow, they had the up and down arrow keys controlling frequency in ten Hertz steps. 73, Bob N7ZO __ 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] New K2: Order of Construction
I built a K2 around 13 years ago, which I sold, and now I'm building a second one. The first one, I put too many options in and the complexity overwhelmed me. With this one I have kept it simple and only have the KAT2, K160RX and KBT2options. I am thinking that I should construct the options first (KAT2, K160RX and KBT2) and then construct the K2 main kit and then install the options during the regular K2 Construction rather than retrofitting the options after K2 building. Is this the simplest and recommended way to incorporate the options during build of a new K2.

Re: [Elecraft] KAT500 remote installation
Knut - It looks good to me. Isn't that MFJ power supply a bit large for the power requirements of the equipment you have attached to it? Or do you have some high-power piece somewhere out of the photos? Cheers - Bill, AE6JV On 4/14/13 at 5:13 PM, ab...@arrl.net (ab2tc) wrote: Hi all, It's been quiet on the KAT500 front lately.

Re: [Elecraft] New K2: Order of Construction
I would suggest you build the K2 first so you can test the options as you build them. The K2 manual indicates when you can install the headers and changes to the K2 in the latter parts of the assembly process. If you build the options first and install them as you go with the base K2 build, should a problem occur, you will not know whether it is a problem with the option or the base K2. 73, Don W3FPR On 4/14/2013 9:50 PM, w1kbx wrote: I built a K2 around 13 years ago, which I sold, and now I'm building a second one.

Re: [Elecraft] New K2: Order of Construction
Dan - Just keep in mind that you will not be able to properly test the optional units until the base K2has been built and tested. Other than that, it probably does not make much difference what order you choose for construction. My personal K2, completed several years ago now, has all the options and upgrades except for the 60-meter unit and the external VHF / UHF transverters, and I did not feel it was overwhelming in any way. I just took it slow, spending perhaps 40 hours on the basic K2, and another 50 hours or so on all the options, including adding the KPA100 and KAT100 in a separate EC2 cabinet. My self-imposed time limit for a building session was set to 2 hours maximum, and no more than 2 sessions in any given day. Made each session both enjoyable and something to look forward to. - Jim, KL7CC On 4/14/2013 5:50 PM, w1kbx wrote: I built a K2 around 13 years ago, which I sold, and now I'm building a second one.
