Re: [Elecraft] RS232 interface
Hi Don. I was aware of the issue with Prolific counterfeits. I probably have at least two of those, including one I bought as genuine for programming a TYT handheld (Baofeng cable). :-( AFAIK Prolific do not render the counterfeit device hardware inoperative. The counterfeits won't work with the current Prolific driver, but they will work with a much earlier driver that does not detect counterfeits. It's also essential to disable Windows Update for the driver. Another thing that Micro$oft have deliberately made obscure! FTDI have only very recently taken it one step further by actually disabling part of the internal ID in the counterfeit chip, but it would appear that they've shot themselves in the foot, because some genuine chips also got disabled and they've had to retract that driver. Also a pointless exercise because their system has already been reverse engineered, including their driver and is being manufactured more cheaply by the Chinese. I sympathise with both companies over protection of their intellectual property, but they've gone about it the wrong way. Certainly in the UK at least, I believe that FTDI's latest action is illegal. FTDI have no right to penalise the end user by breaking the device that they paid for, although it is possible to reverse the action, but most people won't know how. For either company to hit the end user is just downright lazy and cowardly. The general public will not know if they have a counterfeit or not and will lose faith in these companies. The only correct way to stop the trade is counterfeits is by due process of Law, by having copyright and patent laws upheld, instead of being lazy and fixing a driver. It looks like Elecraft are confirming what a lot of knowledgeable people have been saying and that is that even genuine Prolific devices are inferior to FTDI. Presuming that Elecraft have been selling genuine devices (I'm sure they have) they've not changed to FTDI because of a counterfeit/driver war, but because the Prolific devices have given them grief. The device that I've ordered is direct from FTDI in Scotland, so it's 99% certain it will be genuine and hopefully will work OK with the K3. It would be ironic if it also turned out to be a counterfeit! I would have been happy to purchase direct from Elecraft, but it would take over a week and I'd have to pay extra taxes to our government. :-( I'm just intrigued to know why the genuine Prolific devices are so troublesome? 73, Alan. G4GNX -Original Message- From: Don Wilhelm Sent: Saturday, October 25, 2014 3:43 AM To: G4GNX ; Elecraft Reflector Subject: Re: [Elecraft] RS232 interface Alan, Yes, the FTDI chipset adapters are the recommended variety. To further confuse the issue with both Prolific and FTDI serial adapters, there are counterfeit adapters on the market. Those worked with few problems under Windows XP with the provided drivers, but both companies included code in the new drivers to detect those counterfeits and render them inoperative. The new drivers are downloaded as updates in Windows 7 and above. I do think that the number of counterfeit chipsets in the marketplace may be diminishing because of the manufacturers steps to protect their intellectual property, but it is a headache if you happen to have one. I did have one here that was a special cable for a handheld. I finally solved the problem by ordering an equivalent cable that connects to a real serial port or a working USB to serial adapter. It may be that you have one (or two) of those counterfeit chipsets - not saying for certain, but do be aware of that possibility. There is really nothing to setup in the K3 or K3Utility, but it is best that you set the baud rate for both at 38400 - K3 menu CONFIG:RS232. K3 Utility will scan for different baud rates if necessary. 73, Don W3FP __ 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] How do I turn OFF my K3 remotely
John You can send the PS0 command from HRD: MacrosDisplayCAT Comands ( PS0). You will hear that the K3 audio stops and you can then switch OFF the K3 by briefly shorting ACC pin 8 to ground. I use GSM SMS to do that (and subsequently to switch OFF the PSU). An IP power switch may be simpler, but I like to be able to switch everything OFF also if my router goes dead. One slight problem is that you need to be sure that pin8 has been grounded and the K3 has been switched OFF before you switch OFF the PSU. I do that by very carefully listening to the audio (Skype or IP-Sound). But in some cases there may be some delay in delivery of SMS and it may be difficult to ensure that pin 8 has really been shorted ( and you may want to request the relay status by yet another SMS!) But there is a very weak change in the audio noise level when pin8 is pulled to ground and when you hear that you know you can safely switch OFF the PSU. If someone from Elecraft reads this, I suggest to include in a future firmware upgrade something which makes the K3 audio make a beep when pin 8 is pulled down and K3 switches OFF. 73 Paul/OZ4UN Den 25/10/2014 kl. 04.56 skrev Don Wilhelm w3...@embarqmail.com: John, I don't know if or how that HRD does it, but remote power off is available if the software issues a PS0; command to the K3. Note that a powered off K3 is not listening to commands, there is no way to turn the K3 on via RS-232 command. To turn the K3 back on remotely, an external device must pull the ACC connector pin 8 to ground. That may require additional hardware at the remote site. 73, Don W3FPR On 10/24/2014 10:33 PM, John K9UWA wrote: Can someone tell me how to turn OFF my K3 radio remotely through HRD.

[Elecraft] K3 sub receiver gradual noise level increase
Guys I have a K3 that has developed what I think is a fault on the sub-receiver. It is S/N 883. MCU Firmware is at 4.86 If I switch on the K3 and enable the sub receiver, I hear equally as well as the main receiver but after a few seconds, an increasingly loud noise level builds up and the signal level drops down (in this situation, the noise remains present even when the aerial is disconnected). The main receiver operates without any such issues. I have saved a small video file showing the effect and how switching the sub receiver off and then immediately back on restores the receiver, until the noise returns and the signal drops out once again. See https://dl.dropboxusercontent.com/u/43142183/2.wmv I have checked internal TMP connections and also the multi-pin connectors on the sub receiver board, but having put things back together the situation remains unchanged.

[Elecraft] Using the Pigknob
I have been using the Pigknob for several months now and have found it to be a super add-on for the K3 (and some other rigs also). I control the VFO in steps of 1 kc or 100 cycles (user programmable range and push selectable at the control) and have eight (8) other buttons that I program as I wish. In my case: band up, band down, mode, auto-notch toggle, audio level preset (to work with my armchair copy station audio system), and audio level mute (AG000). I still have two more buttons that I am not using - I am leaning toward wide and narrow filter selection or NB toggle. Programming is simple - via a terminal program (I use Putty). I do not normally log, rarely work DX, and never participate in contests. I am a simple rag chewer. This control on a wire allows me to easily use my K3 without having to reach across the desk to reach it (I have mobility issues). I can place the little box on my chair arm or on the desk close to me. I have no business interest in the subject - merely find that it is one of those rare devices that actually works as advertised and is a great assist for me personally. Perhaps others could benefit from my experience. Prior to the Pigknob, I used an older free version of HRD. I still do from time to time - but not often. I never upgraded, as all I need is rig control.

Re: [Elecraft] RS232 interface
That might work for me in conjunction with real RS232 ports. Then I could perhaps control from my Nexus tablet and Android phone. I guess there's always the Pigknob stuff, but the hardware does seem rather expensive. FWIW I'm about to dump the Prolific (maybe counterfeit) hardware altogether except for the Baofeng cable which works fine with my laptop. The reason being that whilst I was experimenting yesterday, installing one of the Prolific drivers crashed the PC into a BSOD and even though I was using a different piece of hardware to attempt to control my UPS, it still crashed u7nexpectedly when I was using it for something unrelated. I've now uninstalled the Prolific driver completely and I'm performing a ReImage repair to ensure stability. The PC has been stable for two years since I built it, so I take drastic action when something like this happens. :-) I also discovered that when I was attempting to get the device to talk to the K3, although I was getting conflicting reports, some communication must have taken place because when I switched the K3 on today, I saw two error messages which were caused by c0onfig changes that I did not make (2 modules classed as installed but not actually present) and the K3 now has my callsign on the startup message. The ONLY way that could have got there is via the RS232 port. I just have to be patient and wait for the FTDI cable to arrive, which I can use on at least a temporary basis to ensure that the config is 100% and save it as a file. 73, Alan.

Re: [Elecraft] K3 problem
Jim, Check the power supply to see if it is shutting off - if it not that, try the K3 into a dummy load. If the problem goes away with the dummy load, the most likely reason is RF in the shack. I did not think I had a problem with RF in the shack until I recently tried working on 10 meters. At power levels above 75 watts, the K3 would turn off all by itself - but no problem into a dummy load, so I have to get some ferrite on that antenna. If RF is causing it, take heed of the wealth of information for attacking it in K9YC's paper on dealing with RFI at http://audiosystemsgroup.com/RFI-Ham.pdf 73, Don W3FPR On 10/25/2014 1:06 PM, Jim Bobo wrote: Just got my antenna up after 3 years of the air and tried the K3.

Re: [Elecraft] [KAT500] Faulting?
The old tube rigs and their frame relay T/R are famous for glitching the leading edge of the first dit or syllable. The problem with arcs is that the arc is not just composed of the single frequency that is creating. The broad signal resulting from the arc will be very highly invested with off-band components There are many faults in the olde stuffe that usually need cleaning up to run smoothly with modern stuff, with the modern expectations. I never had a KAT500 to go with my Yaesu FT101ZD. I also had to use a foot switch for T/R. 73, Guy On Sat, Oct 25, 2014 at 3:45 PM, Don Wilhelm w3...@embarqmail.com wrote: Eric, What is the chance that the transceiver and amplifier are 'spiking' at keydown time.

[Elecraft] KX3 KXPA100 into Ameritron ALS-600S
I want to run my just-born KX3 and it’s 100-watt companion KCPA100 into a high power linear, my Ameritron ALS-600S. But we have some issues. For instance: the combo easily produces 600 watts CW. But, on SSB it far too easily trips the Ameritron load fault, or the KXPA100 high SWR shut down. This rather acts like RF feedback. Maybe I just need to follow better RF hygiene here (higher quality coax cables, making sure RF does not loop back on a power cable, etc.). Any collective wisdom appreciated.

[Elecraft] VFO IND in the KX3?
Good Afternoon, I recently received my KX3 and its amazing. I am very active on the 630m band as a Part 5 experimental station and use an outboard transmit downconverter with an 80m IF to generate a signal. While I have RX upconverters that port to various bands, the native RX seems ok so at least at first I plan on using the internal general coverage RX. I just ran into a problem, however. I need to be able to TX on one band and RX on another, literally VFO A is RX at 475 KHz and VFO B is TX at 3675 Khz. Every time I manually enter a freq, when I presee enter, it changes both VFO's to the same band. I have been told that in the K3, there is a menu setting (VFO IND) to allow independent VFO's but I dont see that option with the KX3. How do I do this? The manual does not indicate any instructions for crossband operation but I do it with my Yaesu's and they seem very happy with this type of operation so I suspect there is a way to make this happen.

Re: [Elecraft] VFO IND in the KX3?
John, The KX3 has dual watch (up to +/- 15 kHz VFO A and B separation within the current band). But it does not allow the VFOs to be on different bands. (The K3 allows VFO INDependent in conjunction with the sub receiver, which also has its own front end filters, allowing simultaneous receive on two different bands). To do what I think you require on the KX3, you could set up 160 m and 80 m for the desired frequencies, then hit BAND+ or BAND- to go from TX to RX. It's still just a single switch press. Regarding 475 kHz receive: My guess is you'll want to use the up-converter. The KX3's sensitivity and image rejection is optimized for the ham bands, and I'm not sure it will meet your needs at this frequency. 73, Wayne N6KR On Oct 25, 2014, at 4:27 PM, KB5NJD jlangri...@sbcglobal.net wrote: Good Afternoon, I recently received my KX3 and its amazing.

Re: [Elecraft] VFO IND in the KX3?
Thanks Wayne. I have an RX converter I can put in line that ports to 80m also. I will just have to create the relay logic for RX/TX but I have all the info and materials I need to do that. Interestingly enough, the RX seems ok down there but I have outboard filters in place. Sensitivity is down a bit but its not a show stopper, or it has not been so far. More real time evaluation is in order. thanks again for the clarification. I am very happy with the KX3 and can apply my workaround to make this fill my need. 73!

You don't need a TRRS plug. You can use a TRS plug. Mic hot lead to the Tip. PTT to the Ring. Ground on the Sleeve. Then, in the Menu, set MIC BTN = PTT. This turns the Mic Button feature off.

See you there. 73, Phil, NS7P __ 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] KUSB - Urgent
Good afternoon (it's Sunday afternoon and 35 degrees C here) Please see my email below - panic over !! I trawled through the websites of various local computer and electronics suppliers and found that Jaycar - a big Australian electronic parts retailer with lots of branches - apparently had a USB to Serial convertor that works with Windows 8 and 8.1. So I just went and bought one and lo and behold it was absolutely plug and play. The K3 and Windows 8.1 are playing happily together again. Interestingly the convertor appears to have a Prolific chip as the Jaycar website has a link (from the details of this particular item) to Prolific where details of all the various Prolific chips are shown together with their compatability with the various versions of Windows. I am also forwarding this to the reflector in case any of my VK friends are having similar problems. 73 Barry VK2BJ On 25 October 2014 18:28, Barry Simpson vk...@optusnet.com.au wrote: Good afternoon My Prolific KUSB has been working satisfactorily for years with various computers up to and including Windows 7. However, I have just bought a small Windows 8 laptop to take on holiday for use with my K3 and the KUSB won't work with it. I think that your new KUSB's with the FTDI chips do work with Windows 8. If this is the case, how quickly can you ship one to me by the fastest air mail possible as I am going on holiday in just over two weeks. I await your urgent reply. 73 Barry Simpson VK2BJ __ 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
[Elecraft] Using a PK232 with the K3
Has anyone used a PK232SC with a K3? If so, how did you connect to it? Thanks.

Re: [Elecraft] Sad news, G4ILO
Indeed, sad news. Julian has faced a brave struggle for a long time and kept his face up throughout it. As it happened I was only looking at his blog yesterday while hunting for XV50 information and wondered how he was. May he rest in peace. 73 Dave G3YMC On 25 Oct 2014 at 22:06, Brendan Minish wrote: I was greatly saddened to hear that Julian G4ILO passed away yesterday http://davesergeant.com __ 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] KX3 KXPA100 into Ameritron ALS-600S
I can tell you that I had similar problems when I tried to do this with the K2 back before the K2's 100-watt KPA100 was available. I tried using an external 100-watt solid-state amplifier (good quality, made by Henry Radio) to drive a one-kW linear. Sometimes it worked, but sometimes there was feedback which caused horrible clicks/spurs, etc. There is a lot of gain external to the KX3 here. I think you have the answer in RF hygiene, which should include separate leads to the power supply for the KX3, KXPA100 and ALS-600S (or separate power supplies). Good coax and liberal use of ferrites might help too.

For instance: the combo easily produces 600 watts CW. But, on SSB it far too easily trips the Ameritron load fault, or the KXPA100 high SWR shut down. This rather acts like RF feedback. Maybe I just need to follow better RF hygiene here (higher quality coax cables, making sure RF does not loop back on a power cable, etc.). Any collective wisdom appreciated.
