Re: [Elecraft] XV144 - does it power spike
Most of the YaKeIc I've ever worked with have this issue. Anytime you use ALC to control the power output there is a chance that that can happen if you are turning the power way down. When the rig is first keyed, there is a window before the ALC voltage is set properly that can allow this. It may be only milliseconds but with solid state devices, that could be all it takes. With transveters in general, they operate from a low level stage and the effects on ALC are either minimal or non-existant. In the case of the K2 and K3's with their external transverters, I do not believe they incorporate any ALC so whatever you set the drive level to, that's all you get. For many years we at K8GP used TS850's to drive DEM transverters using the low level outputs from the 850's and never had an issue. Now that we have many K3's in the group (YEA), they even work better. Now the nay-sayers will condem not using ALC but in the transverter world, the correct way to set one up is to watch the output power while increasing the drive level. Once a peak is reached (or you get to the amount of drive needed for your amp), back the drive off slightly and you are done, you can't overdrive it that way. So while some folks shy away from transverters because they might think they are too complicated, the performance you get from an Elecraft transverter and a K3 FAR outperforms ANY multimode-multiband rig regardless of manufacturer. 73, Merry Xmas to all.

Re: [Elecraft] Feature request - CW PTT
I understand the explaination as the PTT acting illogical. And yes, no other rigs act like this. I believe this is a carry over from several years ago when an update was made that fixed an issue that even in PTT mode, if the key was hit it would actually transmit. Now at least it doesn't transmit but yes, the KEY OUT does close and it shouldn't; in PTT mode, it should just look at you until you press the PTT. Maybe this discussion will jog Wayne's memory and he can have another look at it to see if it can be corrected.

Re: [Elecraft] K144XV receive gain
I've done extensive testing and Eric confirmed that the gain is fixed, only the s-meter reading is adjustable via firmware.

[Elecraft] K3 Feature request
Now that the K144XV is available and a lot of us are planning to use it to drive microwave transverters, it would be really nice if there was some way to easily adjust IF gain. I know there was a gain change after 3.97 so it appears this is available in the firmware. Is there a way that along with RF freq, IF freq and offset offered in the XV config that there could be a gain per band setting added? When you add a transverters, most times the transverter has a fair amount of conversion gain and having the S-meter sit at S5 with noise doesn't help dynamic range. For eme'ers, we typically have lots of gain in preamps that drives the S-meter up. Using the ATT works but it's either in or out, nothing in between. Just a thought.

[Elecraft] K144XV receive gain
After seeing several postings about the K144xv gain and experiencing issues myself, I did some testing. Comparing a K3/K144XV on 2m vs 6m. On version 3.97 firmware, on 6m -87dbm yielded a S9 signal with the PR6 preamp in but the internal preamp off - best setting. On 2m, this yielded a S9+5 signal with the internal preamp still off. After loading 4.12 or higher, the same -87dbm gave the same S9 on 6m but now only S5 on 2m and still only S7 with the internal preamp on. To achieve the same S9 reading, I had to increase the signal level to -72dbm with the internal preamp off. The release notes for 4.12 reference a gain change on the K144xv and by the results of the 3.97 test I agree, there was too much gain but instead of dropping 6 db or so, it appears that they dropped 15db. Hopefully this will be rectified in the near future.

[Elecraft] [K3] Separate PTT outputs for HF, 6m and Transverters
Hi all, I have built a number of interface boards for my K3's that some of you may be interested in. Since a K3 only has one PTT output, I have built an interface board that takes the LP Keyout, DIGOUT0 and DIGOUT1 and generates a separate PTT output for HF, 6m and non-Elecraft transverters that use the low power outputs from the KXV3. It also provided a switched 12v to control the 6m preamp since DIGOUT1 is used on this board. The board contains 6 RCA jacks, one is 12v in from the 12v jack on the K3 rear panel and another RCA is provided with 12v out. There is a switched 12v jack that is activated on 6m for the remote preamp and then the 3 PTT output for HF, 6m and VHF transverters. This is not in competition with the KRC2 which does band decode and lots of other cool stuff, this is a quick and easy way to control amps and transverters. It is NOT for folks running QSK as the relays are typically 35ms switching. I will have some pictures up on the K8GP website tonight. I have about $30 in parts and will provide the units assembled and tested. You will have to provide a interface cable with a DB15HD for the ACC connector on your K3, the other end of this cable connects to this board via a push on connector (supplied) and a suitable enclosure. If you are interested or have questions, please reply off list directly yo me. 73, Terry __ 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

I own two K3's and maintain 6 others for our contest group. I've never had even a hint of an issue with the RS232 interface loading/saving configs or firmware. I might add to all K3 owners as I've learned after many years of working with networking gear. Load new firmware when it is available, even if you think you don't need the new features. Even though companies much bigger than Elecraft (Like Cisco) try their best to maintain backward compatability, it doesn't always work.

Re: [Elecraft] K3 Ground Loop Issues using Ameritron ARB-704
Haven't followed this too close until I saw Ameritron. W3ZZ had almost the exact issue very early after receiving his K3 when they first were released. For him the issue only showed hum on 160m but the problem turned out to be the QSK mod factory installed on his amp caused there to be a DC voltage on the RF coax between the K3 and the amp. Since there is no DC blocking cap between the antenna jack and the SWR bridge in the K3 (or at least then there wasn't) this caused the DC voltage to be grounded and caused the hum. I added a .01 HV ceramic disc right at the input jack of the amp. Disconnect the amp completely from the K3. Measure the DC voltage from the center conductor of the coax coming from the amp to ground and key the amp. If there is any DC voltage there, you need to add a blocking cap. YMMV - This is only what I found and it worked for him.

Re: [Elecraft] K3: Do you Juice your K3?
I believe the way ALC works in the rig, unless you tell it you want more, it wouldn't do it even if you increased the capability. And it is the software that tells it how much to put out, so unless you change the software so it will go above 120w it won't. Unlike, say a TS850 where you just turn the ALC pot up on the inside. Higher voltage may lower the IMD but at what cost? What does it do to the MTBF of all the components that are rated say at 16v. I would like to hear Wayne's thoughts as a designer on this.

Re: [Elecraft] Elecraft 70cm transverter, K3 and repeater access tones?
While I don't have a 432 Elecraft transverter, I have had a lot of experience with DEM transverters and K3's over the last year. If you change the crystal in the transverter to use 26 MHz for 432 then 30 MHz would be 436 and this works well with a couple of caveates. The bandpass filters start to cut off pretty sharply around 27 MHz and you will find the rx is down about 6 db, mostly not a problem since most transverters have ample gain. On the transmit side, I have found the output is reduced to about -6 dbm and isn't as adjustable as it is at 28 MHz, probably ALC action with reduced output from the bandpass filters. I have used it and it works well, you just have to play with the levels and as you go up in frequency, you have to watch that you don't overdrive the transverter. DEM offers a crystal that allows their transverter to cover 435 with a 28 MHz IF, this equates to a 25 MHZ IF for 432 and the 12m bandpass should work well for this but once again, as you go up, the bandpass will be dropping until you reach around 27 MHz. I have considered re-tuning the 10m filters down to give flatter response at 26MHz giving away 28.8 and up which I never use anyway but haven't decided which way to go. Since the FM band in the US is 440 to 450, it's a waste since nothing you do is ever going to give you 20 MHz of bandwidth. I just keep a 70cm FM transceiver around and just use the K3 for weak signal work around 432. Hope this helps.

Re: [Elecraft] K3 external qro keying line
I've seen numerous posts about the PTT output line on the K3 and using older amps. Yaesu's, Kenwood's, Icom's all share the same issue. Unless you are running QSK and need instant keying, I would suggest adding a small 12v relay inside the K3 that the solid state device keys and presents the user with a set of dry, isolated contacts that can handle positive, negative and up to 250v DC or AC. I have added this to several K3's to protect the switching transistor from eventual destruction. Once again, if you are using QSK, solid state due to it's fast switching time is your only option. Yes, it means touching your K3 with a hot soldering iron, but it's a pay me now or pay me later thing, sooner or later it will blow the switch if you are hooking up older or HB amps that use other than low current positive keying voltages.

[Elecraft] K3 transverter output question
Not sure if this is a question or observation. Saturday I was setting up a DEM transverter to be used with a K3 and found the low level output of the K3 is dependant upon the input attenuator setting on the DEM transverter. I set the max output on the K3 in the menu to 1.8 dbm , which the rig displayed. When the DEM was adjusted for max attenuation, the K3 showed 1.8 dbm but when I turned the attenuation pot on the DEM transverter to decrease the attenuation and get more output, the output of the K3 dropped to .7 dbm as noted on the K3 readout. A assume this is because the 10m input of the DEM is not 50 ohms but it just surprised me after dealing with many other rigs. I guess even the low level output is ALC controlled which would probably explain it.

Re: [Elecraft] Silly question - what is KEY OUT?
This isn't a bug, it's the way it was implemented. Originally, whenever in cw, hitting the key would cause the rig to transmit, either in VOX or PTT mode. A change was made so that the rig would not transmit unless it was in VOX or the PTT was engaged. In PTT mode, the rig still keys but doesn't output any RF; different from the way most all other rigs behave but it works. Hopefully, once Wayne gets peoples' Duckies included, they go back and set it so unless in VOX mode the rig doesn't even key when the paddles are closed. Terry -- Original message -- From: Merv Schweigert k...@flex.com The Key Out relay is only energized during transmission. This is what you would want for an amplifier. So for example if you turn your VOX off and press your key or paddle, the Key Out relay will not energize. If you turn your VOX on it will energize but you will also be transmitting. If you are in normal VOX control, the Key Out relay will stay energized longer than your key press based on your VOX delay setting. So it won't follow your dits and dahs. I suppose if you turn QSK on, the Key Out will follow the dits and dahs of your key presses or the internal keyer. May be a bug in my K3 2306, but if you hit the paddle the key out does key the amp with the VOX turned off.

In general, TX and RX antennas should be well-isolated. If you hear the COR (carrier operated relay) on any K3 activate -- either the one on its RX ANT jack or the sub receiver's AUX input -- you should try to improve isolation. You'll know it when you hear it, because T-R normally involves only PIN diodes on a K3. There will be extreme cases where a band-pass filter or external shorting may be required, depending on the situation. There are many multi-K3 installations, some permanent, some for DXpeditions. We've had many reports about the ability of the K3 to function well in such cases -- often much better than older rigs. I'm sure you can get further help in specific situations from some of those monitoring this list. I'm not the right guy to ask, at least at present.

With MON, you hear the slightly delayed audio from the monitor as well as your own voice. This may be perceived by some as a slight echo. The delay is due to how DSP works. Tx audio is processed by the DSP (leveled, filtered and equalized), converted to a nominal 15 kHz IF, clipped (if compression is on) and then sampled, downconverted to audio, filtered again, and passed to the speaker or headphones (or, now, LINE OUT :-) There is some delay associated with all of this processing. This is most likely what you are hearing as a slight echo effect. If you record MON and then play it back while you are not speaking, you'll hear no echo.

[Elecraft] RX audio in both ears for sub receiver
If the K3 has the capability, the best would be to supply both ears both main and sub receiver audio but add a slight delay to the left ear for the sub receiver and and a slight delay to the right ear for the main receiver. This will give the good old stereo effect that the main receiver is on the left and the sub receiver is on the right. I've done this for many years using two radios and audio delay boards meant for repeaters.
