Re: [Elecraft] K3 receiver troubleshooting
Guy, thanks for the tip. I will give it a try. A relay in the kxv3 rev 2 failed, an Omron part. It is now obsolete. Elecraft sells a new rev 3 version of the kxv3 for $88 as an upgrade. You trade in your defective module. The failure occurred during the night that we had electrical storms so I assumed some solid state part in the rx path had probably gotten zapped. But we could inject a weak signal after the kxv3 and hear it, but not before it. Of course that sounds like a simple diagnosis, and it is when you are reading the final outcome, but not when your rig is spread out on the bench.

[Elecraft] K1-4 4 band version gone?
All this talk about the K1 backlight led me to look back at the K1 order page. There is no option for a 4-band version, nor for the KFL1-4 4-band filter module itself. Is this an oversight, or has the 4-band board been discontinued? If so, when and why? Also if so, then the K1 description page should be edited to remove reference to the new 4 band board... or at least explain that it is no longer available.

P-T, If you follow the instructions frequently given on this reflector, you will have proper power control and no flat-topping. For soundcard Data modes, monitor the audio input level on the ALC meter. You should have 4 bars illuminated with the 5th bar flickering. The first bars of the ALC meter do not actually indicate ALC - the onset of ALC is at the 5th bar, so the lower bars are used like a VU-meter to aid in adjusting the audio drive level.\ The closed loop method of power control used by the K3 requires that you fully drive the audio and use the power knob to set the desired power output.

Hi Johnny, Martin of SCS has been quite friendly towards me. He tried to help me even if he was on vacation. What more can one ask? However, I'm a bit disappointed over the documentation for the P4. So far there is only an installation manual. The full manual with command description etc. is missing. I had to download the manual for another modem in order to get info on the command set. And I've not so far found any information of the misc info that can be displayed on the P4 screen.

Yes, Bruce, it looks like this: /T//he K1...A compact, high-performance CW rig that _you_ can build./ // /HF operation is more fun than ever these days--five watts is all you need to work worldwide DX. That's why we've packed up to four bands into our affordable, easy-to-build K1-4 transceiver. You can order the K1 as either a four-band radio *(K1-4)* or a two-band radio *(K1-2)*. The new four-band K1-4 covers 40, 30, 20, and either 17 or 15 meters. (All band parts are supplied with the kit and 17 or 15M are chosen as the last band at build time.) You can also upgrade the K1-2 to a K1-4 by purchasing the four-band KFL1-4 module and replacing the KFL1-2 in your original K1-2. The KFL1-2 two band module covers your choice of two bands (80, 40, 30 20, 17 and 15 meters available). Combining a K1-4 with an extra KFL1-2 band module on 80 + (15 or 17M) gives you all six bands on your K1! Both module types simply plug in to the K1's main board, internally, and you can swap either type in at any time./ needs an edit -- unless lack of a 4-band module is a temporary situation.

[Elecraft] Fwd: Re: K1-4 4 band version gone?
Really? Thought I saw one. Hmm ... I just took a look and it looks like you are right; maybe now you have to change out two band modules. If so my 4-band K1 is now golden. Perhaps Elecraft is phasing out the K1? Or maybe some part no longer available. It's been around a while: I built S/N #18 during my K2 process. Adding the backlight mod this weekend if it arrives in time. And I'm going for the bright option: 0.006 Amps vs. 0.010 Amps? 4 mA won't shorten my operating time on batteries much!

Re: [Elecraft] K1-4 4 band version gone?
Bad news...for those who don't have one. The K1-4 was my introduction to both Elecraft and purpose-built QRP rigs. It's easily in the top 3 favorite radios I have owned in half a century. I think Gil called it a cute mini K2 in the link below, and that's a pretty good description. It's big enough to operate like a real radio in the shack. It's small enough to take anywhere. It tunes smoothly and sounds exceptionally good. It has everything you need for CW and nothing you don't. The KX1 isn't a good substitute for the K1, in my opinion. It's a very specialized rig with lots of compromises for those who need minimum size and weight. After the initial fun of a new rig, my KX1 has been sitting on a shelf with very little use. Whenever I grab it to go camping, I pack the K1 as well just in case. Then I end up using the K1 the entire trip. If I was a backpacker, the roles would probably be reversed, though.

Re: [Elecraft] K1-4 4 band version gone?
The part that has become unavailable is the blue trimmer capacitors that are used for tuning the bandpass filters. That does *not* spell demise of the K1, but only the 4 band board. Yes, sorry that it is gone, but the K1 with a 2 band board and an extra 2 band board will give you 4 band capability - and you can mix and match the 4 bands in any combination of 2 bands that you want. In other words, the choices are more flexible than with the 4 band board. 73, Don W3FPR On 7/17/2014 1:46 PM, Phil Wheeler wrote: Bummer -- and Lisa's exact words from that link were more definite and final: /The 4-band board was discontinued due to a part availability issue that was crucial to the functionality of the KF1-4.

Re: [Elecraft] K1-4 4 band version gone?
Hi Bruce, The 4-band module requires extremely low-temperature-coefficient trimmer capacitors because of its narrow-band pre-mix and RF band-pass filters. The last source for these exotic trimmers dried up recently. A redesign using higher-TC trimmers might be possible, but the filters would end up being triple-tuned, which would force the use of SMD components throughout, and tuning the filters would then be very difficult without a spectrum analyzer. Sales volume for the K1 has decreased in recent years due to the KX1 (which is smaller and has a DDS VFO), and the KX3 (which covers all bands, all modes, with up to 12 W output and has a much more capable auto tuner, nicer user interface, etc.). So the cost of a redesign wouldn't be recovered. That said, for the time being we're continuing to offer the two-band version and the other options (KAT1 ATU, KBT1 battery pack, etc.). The K1 is one of our full kits, and has a bit of a fan club of its own. We'll update the website to reflect the change in option availability. 73, Wayne N6KR On Jul 17, 2014, at 4:13 AM, Bruce Beford bef...@myfairpoint.net wrote: All this talk about the K1 backlight led me to look back at the K1 order page.

Re: [Elecraft] K1-4 4 band version gone?
Thanks for taking the time to reply with the details, Wayne. It's a shame. I (and many others) feel the K1 has some advantages over the KX1, such as the analog VFO, higher output power, and 4-pole filtering. It's internal antenna matching unit also offers more tuning range than the KX1. I have also built a 160m/80m 2 band board for mine. I have built and own all the Elecraft rigs, and each has provided great enjoyment, each has it's strong points. Time marches own, it would be wonderful if a 4-band redesign solution could be found, using modern components. Perhaps a pre-built, pre-tuned SMD based board. But, I imagine the potential sales volume would not justify the costs. Too bad.

The last source for these exotic trimmers dried up recently. If all the other parts of the KFL1-4 were still stocked, perhaps those original white ceramic trimmer capacitors could be used again. I used my KFL1-4 for two years with those because I did not want to pull and rebuild the KFL1-4 I built in 2001 after the blue trimmers were made available. Yes, I did need to re-align my KFL1-4 about every six months when the original white capacitors were still in place. This would be an unfortunate compromise, but I'd rather have even the original KFL1-4 with those problematic trimmers than use two KFL1-2 filters to get four bands. I used two KFL1-2 boards (40/20m and 30/15m) prior to the availability of the KFL1-4. Sales volume for the K1 has decreased in recent years due to the KX1 (which is smaller and has a DDS VFO)... I greatly prefer the performance and physical form of the K1 over that of the KX1. I never bought the BS that some KX1 owners slung around after KX1 introduction that the KX1 replaced the K1. Did it?? Try using that KX1 on 15 or 17 meters. Even for backpacking, the K1 is a far better radio to cart along if ham CW band RF performance is valued. The K1 is also less quirky to build than a 80/40/30/20m full-house KX1. ...and the KX3... I believe that there are a number of advantages of the K1 over the KX3 when the extreme sophistication of the KX3 is not required. The K1 is much lighter, less bulky, much lower power consumption, and is incredibly easier to fully master than the KX3 is at even the neophyte level. I purchased the K1 after seeing its introduction at Dayton 2000, and then waited the six months for delivery of #175 in November 2000. After almost 14 years it remains my favorite and most utilized HF ham rig owned in 46 years as a ham. It is a very very good radio, and I greatly admire Wayne's design for this classic QRP rig. Thanks, Wayne. So the cost of a redesign wouldn't be recovered. I've always thought that the K1-line would be the first to be discontinued. I am pleasantly surprised that the *start* of that is happening *only* now. It was a very good run for a great QRP radio...those 14 years!

[Elecraft] KX1 Receiver issue
I have had my KX1 for close to ten years now, and it has been a great traveling companion with lots of fun QSO’s. Two nights ago, I got the rig all hooked up and discovered that no audio was emanating from the headphones. The AF gain control, filter pot, and RF gain control made no difference. I hooked up the paddle and found that the TX is working fine, and I could hear the side tone through the headphones. To see if a loud signal had any effect on the KX1 receiver, I put a dummy load on my K3 and sent some test tones, none of which were being received at close proximity. This problem occurs across all 3 bands. The antenna tuner is working, and my SWR meter show a perfect match. Any suggestions as to where I should start troubleshooting? Tnx.

However, with OE the sound quality is greatly improved. Any idea why? Several possibilities. How old are you? How much hearing sensitivity have you lost due to exposure to loud radios, loud music, noise at work, use of firearms? The audio output stages in Elecraft radios are not designed to produce the very high levels needed to overcome a lot of hearing loss, and may run into distortion when asked to do so. Wayne designs them this way to minimize current drain -- all of his radios are designed to be good back-packing radios too. I worked in pro audio for a lot of years, so I have hearing loss both from that and from my years in ham radio. The output stages in my Elecraft radios are good enough for my hearing loss, and my expectations of what a ham rig should do, but they may not be good enough for everyone. All headphones are not created equal, even good ones. Their load impedance and voltage sensitivity can vary over a wide range. The Bose headphones may have greater voltage sensitivity, so the Elecraft output stage doesn't have to work as hard. One thing that all of us can easily do is use RXEQ to get rid of low end noise that is of no use for communications, but burns some audio headroom. I have RXEQ in my KX3 set to max cut on the three lowest bands. Cutting the two or three lowest bands on a K3 would probably help headroom by about 2 dB. 73, Jim 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 Message delivered to arch...@mail-archive.com

Re: [Elecraft] K1-4 4 band version gone?
Here's another thought that perhaps one of us could put together: give up the internal battery space for a considerably larger filter board that could be used to allow room for additional 2 band style filters that don't share components (and, thus, don't need high-tolerance parts). No new parts would be needed; the existing 2-band parts kits, and the controller from the 4-band board would serve. This would also open the door for selecting a completely arbitrary set of four bands (eg 15/20/40/80) as the filters would, again, be completely independent of each other. I'll have to give mine a close look for mechanical feasibility when I get home. -kb7psg On Thu, 17 Jul 2014, Wayne Burdick wrote: The 4-band module requires extremely low-temperature-coefficient trimmer capacitors because of its narrow-band pre-mix and RF band-pass filters.

Re: [Elecraft] K3 weak rx audio when AFX is NOT active?
Problem solved! it seems a brand new 4' long 3.5 male to 3.5 male cable was the culprit, when I removed it from the mix, the problem went away. Some how Murphy managed to mess with the cable, and my feeble mind. It went from out of the box working one day, to weird failures the next day, all in only 8 hours, sigh. With the recent 'I blew up my audio chip' thread fresh in my mind, paranoia took over, and I feared the worse, due to the loud pop I hear when I turn on/off the new amplified M-Audio AV40 speakers, so figured I had killed something. It's still very weird that it would change/fail only with the AFX on/off setting? I will be purchasing/installing the K3AUDPROTMDKT in the near future! http://www.elecraft.com/order_form_parts.htm#K3%20Parts quote Even though the K3’s audio output I.C. has internal protection, a small number have failed under extreme conditions such as a dead short across the speaker output. This modification adds a 1-ohm resistance to each speaker output that tests show prevents failure even under these conditions. Some soldering of leaded parts is required to make this modification. Included with all new K3s shipped after mid May 2013. /quote $9.95 seems like a very cheap price to pay for the piece of mind that a bit more insurance against a potential Audio IC failure.

Don wrote: The K1 can remember the frequency offset settings for 6 bands... The K1 remembers the frequency display calibration settings (OFS) for all *nine* HF bands between 160m and 10m (60m is excluded), and automatically uses the one previously stored for a particular band when that band gets assigned to a filter board's b1 or b2. ...so having 3 2-band boards is quite practical. You get to choose which 2 bands go together on one board for most of your operating pleasure. It is worth noting that a small problem will arise if multiple KFL1-2 boards are built that duplicate one of the bands...such as a board for 40/20 and a board for 40/15, both for the same K1. The K1 MCU can remember only *one* frequency display calibration setting per band. In the example I use above, one of those two boards will have some calibration error on 40m unless the 40m heterodyne crystal frequencies of both filter boards are very nearly the same frequency. They'll likely be close enough.

Re: [Elecraft] KX1 Receiver issue
Len, If you can hear sidetone, the audio amplifier is working, that means you can start with the Product detector and/or the muting transistors. Check the voltage on the gate of Q2 and Q3 - if it is zero (or very low), then check U1 pin 6 (the /MUTE signal) - If that pin is also low, you may have a bad output from the firmware IC - best check is to substitute another firmware IC. If the /MUTE line is OK, then try tapping on pin 1 of U5 - do you hear any clicks in the headphone? If so, the product detector is working. If you have something to measure RF voltage, measure the RF voltage at U5 pin 6 - you should have at least 200 mV peak to peak or 40 mV rms (as read by an RF Probe). The next place to check is U6 pin 4 - the output of the Rcv Mixer. If you have nothing there, the only components between there and the product detector input is Q8 and the Xtal IF filter. All OK so far, tap on U6 pin 1 (input to the RX Mixer). If you have noise there, all but the front end if the RX is OK. You can check the RF voltage level at pin 6 - like U5 pin 6, you should have at least 40 mV rms or 200 mV peak to peak. Still all well to that point - there is a possibility that Q7 is either shorted or conducting during receive. Check the DC voltage on the base - it should be zero volts. If you suspect Q7, it can be removed for receive (but not transmit). If taking it out of the circuit restores receive, replace it.
