Re: [Elecraft] K3 and WSPR
Hi Mike I had problems till I used Data A mode with VOX on. Link up the serial cable - you will have this done anyway to update the K3 firmware. Then in WSPR set-up make sure the sound card is specified correctly, the power used (a look up table for dBm in the manual), get RTS to switch on transmit, checking this is OK in the K3 menu (PTT-KEY)Check the port corresponds with the computer. Enable CAT and put in the rig used from the pull down menu, no handshake, 8 data bits and one stop bit to suit the K3, Save settings (in FILE menu) Cables use line in and line out to line-in and audio out of computer. Set K3 main menu for LINE IN. You will have to adjust line in gain and audio out to suit your set up so to have 5 ALC bars input on transmit (use WSPR tune button) to dummy load. Useful to turn off PC monitor speaker or you will hear the program output audio! Wide IF filter is fine. Use standard frequency transmission to adjust VFO to zero beat, if you have the K3 TXCO this will ensure adequate stability, if not a long warm up...If not you will get a drift measurement in the reports. Use web time e.g. D4 program to get time accurate to a second or so. Get reception working first. Use preamp/ATT to get audio into WSPR about 1dB for clear frequency. Too high and it will not decode properly but do not use RF control to reduce or sensitivity will be lost. Adjust frequency to position not occupied by others in reception period. Transmit up to 20% of the time, if you have the latest WSPR use transmit first to avoid waiting too long. 5W is max needed, I have heard ZL from UK and 100mW gets reception reports from around Europe. 1W on 80m gets to the USA in the morning here! I've probably forgotten something so any problems, let us know. The manual is good too!

[Elecraft] K3: Erratic behavior of REV button
Hi Jeff, I experienced the same behavior. But after some investigation i found here it was a user error. Unfortunately the A-B (Split) button is just beside the REV Button. So when holding the wrong button because of my fat fingers the Split is gone and UP calls are generated ;-) Suggestion to ELECRAFT: in LOCK mode also lock A-B (Split) button - I normally run the pileup with locked VFO. If this would also lock the A-B (Split) button this problem cannot happen. Just turning off Split will need holding two buttons instead of one. But in pileup Split mode I do not need to go to the DX QRG. There are normally more than enough UP callers. 73 de Olaf - DK2LO -- NEU: FreePhone - kostenlos mobil telefonieren und surfen!

[Elecraft] P3 Temperature Specs
Hi all, I experience the same problem. It needs some time before the P3 displays the right frequency. It is much worse when it is cold. Now in winter time before sunrise early in the morning it is pretty cold at my station, sometimes only 13 degrees Celsius. Then it needs several minutes. At 20 Celsius it needs around 1 minute. First the P3 shows 0.0 frequency. After some time it shows frequency 36.nnn and then after some time the qrg is ok but cursors are out of display. Then after reboot of the P3 everything is ok. It is definitely worse when it is cold. 73 de Olaf - DK2LO -- GMX DSL Doppel-Flat ab 19,99 Euro/mtl.!

[Elecraft] P3, APF and diversity in CQ 160 contest
P3 and APF were an excellent in the contest for SP. P3 set up for BW of 2 KHz would show weak DX, and APF would pick it up. The position of P3 next to K3 beats a panadapter window on a computer. I worked tons of DX without ever looking at the cluster. Just look at weak signals on P3, tune and work. Signals not showing on P3 were generally too weak to copy. APF was different story for RUN. Turning on APF was too slow. Having an option to switch XFIL and APF for CW only would be great. I guess software APF toggle change via PF key may be good enough. P3 was very helpful for finding a clear frequency and also adjusting it, with a twist. That is, the free frequency could be used by a DX that was too weak to hear (without APF) but visible on P3. Some gremlins got into N1MM here. Every so often, written callsigns would disappear, SPLIT would show up, and work frequency would change from 1820 to 18200. Reloading CONFIG would cure it. Not sure whether it was KUSB, RF or Vista.

I never used APF in the CQ 160 (who has time to tune in 5 Hz steps using SHIFT or 1 Hz steps using VFO?) but here's a good tip for casual operating from Wayne N6KR: Use Preset I and II to toggle APF On and Off more quickly.

Occasionally I noticed VFO B was not on my run frequency! Could be I touched the VFO B knob (which is a good reminder to always LOCK VFO B when operating like this).

[Elecraft] K3 Power On
G'day, A while ago I reported occasional hang when powering on the K3. Lock up which needed power down and on again to recover. I think I know what causes it. I switch everything off when not in use and it is very easy for me to switch on the PSU (switcher) and then hit the K3 power button within 1-2 seconds. If I slow down on powering the K3, maybe all of four to five seconds after PSU switch on, all is OK. So maybe it just takes a few seconds for the K3 supply rails and logic to settle when first powered.

[Elecraft] K3 Firmware Reload Reminder
I know this gets mentioned regularly but it sure worked for me today. I got a very strange behavior after loading FW 4.25. My S meter would jump to full scale whenever I reduced the bandwidth below 500 Hz and the RX would go dead. After a lot of head scratching and unplugging of cables to eliminate issues, I reloaded 4.25 and everything just worked perfectly again. I guess the bits and bytes get crossways occasionally and a nice reload puts everything back in order. I hope you think of this faster than I did if you ever need a bit of help. 73, Bob K5WA __ 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] K3 Power On
Mike - The K3 is a software defined transceiver so needs time to boot up and to close down. You should always switch off your K3 with the Power switch on the front panel. Switching off the power at the supply would be like shutting your computer off at the supply without first closing down Windows. If the K3 power is cut, it will take time to recover when you next switch it on. That would be a risk as it might even cause some corruption of the firmware. 73 de David G4DMP In a recent message, Mike Harris mike.har...@cwimail.fk writes I think I know what causes it.

[Elecraft] P3 Markers A B problem?
When I first got it, turning on Marker A or Marker B would start out with the markers centered. You could then move them to where you wanted either A or B to QSY to and tap the button. With VFO A, the P3 moved that signal to center along with the marker. If you shut the marker off, and moved VFO A, the next time you turned the marker on, it was centered. Now, it stays on the last position of VFO A. Don't know what I did to cause this. If you set marker A to center freq, it will stay there through several moves of VFO A and then start staying at the last position of A. Getting frustrating. The way I perceive that it should work, if the marker is off, when you turn it on it should come up in the center of the display as that's the current frequency the VFO is tuned to. This should be the same for either VFO A or B. Any Ideas? If I'm not thinking correctly or doing something wrong, I can't find it in the book which is currently somewhat sketchy on this subject. I did a complete parameter reset and it still does this. I don't remember it doing that when I first got it.

[Elecraft] P3 Markers A B problem? Disregard previous posting
Disregard my earlier post on this subject. I figured it out. If you move the VFO far enough to go beyond what you have the span set, it centers up the marker again. Hadn't noticed that before, but finally figured out why it would be off center at times and center up at others. With the marker on, if you move the VFO, the marker stays on the previous frequency as a place holder so you can just tap the button and get back to where you were. Handy at times, but haven't found it mentioned in the book or release notes unless I just missed it.

You can also set different XFILs using the Presets. Preset takes some time to change but it may be better than pressing APF. With APF I was able to copy many weak stations on K9AY when running. Notably KH6 and KL7, plus a few WI stations, I guess, running 5W with mobile antennas. But if it takes 1 sec to turn on APF, and an average station calls once, one cycle is lost. After a weak station repeats a few times, other stations decide to use the same frequency for RUN. I find RIT good enough for APF, and faster.

Re: [Elecraft] looking for a part
Have you considered the MBR60100CT that Digikey stocks and sells in single units? Still a 100V common cathode pair of Shottky diodes. With a much higher current rating. And as an added benefit a lower Vf. It does have a higher reverse current (IR) when at high blocking voltages and a hot die. Would that be a problem for your application? At $3.86 each its higher cost shouldn't be a killer for a small project. Yes it is ten times the cost of the MBRF10100CT but still less than the shipping charges.

Re: [Elecraft] KPA 500
Hi Albert The old standard of 220,230,240 volts +- 10% has been gradually deteriorating to plus minus anything! The mains voltages in many places now goes up to and regularly runs at 260 volts! The global de-regulation and privatization of power assets globally has seen standards go down the drain everywhere. Most quality switch mode power supplies are designed for voltages as high as 260 high volts with a plus 5% rating. Many designers and export countries have not caught up with the global deregulation of mains voltage standards. In many places this has been allowed to happen in the hope that a global standard will develop. I can buy energy saving globes that are rated to work at 260 volts(Philips). Many TV's from the Korean companies are designed to work at 260 volts. There is still a lot of new equipment designed for either 220 and 230 volts nominally. This well defined standard is hardly the reality anywhere these days even with the +- 5% allowance The Tokyo high power amp looks interesting. They appear to be using VRF150's. If they have biased this amp very well they will achieve good IMD results. SPE amplifiers using the MRF150's dont achieve the best IMD performance which can be obtained from these devices. The Yaesu FT-5000's PA appears to be very well designed. The 3rd order IMD figures in Class AB according to the reviews are almost as low as Class A at 200 watts of output. They use VRF150's This a is a very good achievement by Yaesu and is a benchmark in terms of IMD performance. I doubt that the Tokyo High power will achieve such good results because THP have always used just the bare minimum bias on all their amp designs. IMD optimization has never been a design goal of theirs. I had a good chat with the designer one day and he was open and candid about this issue. Mt homebrew MRF150-EB104 amp easily achieves -40db 3rd IMD figures on all bands. My surplus ERB MRI amplifier which I bought on Ebay does even better than -40db 3rd order. These are all below one of 2 tone figures not PEP figures. The Elecraft KPA500 will use VRF2933's for which no IMD data is provided on the data sheets. I dont know why Microsemi leaves out this important data. Macom religiously supplies extensive IMD data versus bias current which makes choosing devices very easy. Anyway this will hardly be concern for anyone since the radios always have worst IMD performance than the amplifiers. I will watch the reviews and see how they both perform, the market is getting crowded! I will make my donation once I know how well they perform. It would be nice owning a compact 500 watt amp that performs well without all the mess and surplus rubbish hanging off the amp. 73 John --- On Sat, 2/5/11, Albert Crespo f5...@orange.fr wrote: From: Albert Crespo f5...@orange.fr Subject: [Elecraft] KPA 500 To: elecraft@mailman.qth.net Date: Saturday, February 5, 2011, 9:43 AM Tokyo High Power has produced a 600 watt amplifier, HL-550FX , http://www.arraysolutions.com/Products/THPtop.htm that can handle a wide range of voltages, so it is ideal for places with bad voltage regulation.

Re: [Elecraft] KPA 500
Hi Albert I just looked at the picture of the inside of the THP amp. http://www.tokyohypower.com/hl-550fx_i_pop.html I am not impressed with the construction. It looks a lot like an Ameritron inside. At most it looks like a EB104 CCI amp with a power supply and a low pass filter board in a box. The cooling looks to be primitive at best. I also dont like the switch mode power supply being so close to the high pass filter board. This is a recipe for noise and other problems. There is also a general lack of shielding. This might be ok for for 500 watt amplifier, however its very öpen I dont see real value in this amp especially after looking inside it. I would be more inclined to go buy an Ameritron AlS1300 which represents good value and has similar or better construction. It would certainly have better overhead in terms of output power. 73 John --- On Sat, 2/5/11, juergen plebia...@yahoo.com wrote: From: juergen plebia...@yahoo.com Subject: Re: [Elecraft] KPA 500 To: elecraft@mailman.qth.net, Albert Crespo f5...@orange.fr Date: Saturday, February 5, 2011, 3:33 PM Hi Albert The old standard of 220,230,240 volts +- 10% has been gradually deteriorating to plus minus anything!

Hello John, THP is a manufacturer for commercial equipment as well as per their web site. I just don't know why their ham amplifiers are so primitive. They should have the technology and know how. My past experience with THP in HF is not promising. V/U linears are ok. I would always see linear + ATU as a package. Therefore, THP + its own dedicated ATU is not that cheap.

Re: [Elecraft] KPA 500
THP's amps are anything but primitive. Check me if I'm wrong but they are the only manufacturer producing a legal limit solid state amp. The THP 2.5KFX. Notice I said legal limit, not close to or in the neighborhood, or might make it if the wind blows just right, but legal limit. The design for that amp was hashed out on the pages of QEX. It is expensive but not Alpha 9500 expensive and it is one of a kind. Why hasn't anybody else designed a legal limit solid state amp? 8 MRF-150's are about the same price as 2 Microsemi ARF-1500's 50V high current DC supply vs 200V high current DC supply (in the box). Same stupid proof auto-protection systems all the other not quite there amps employ. Well, maybe not. I don't think any of the MFJ amps will auto band switch without buying their little add-on decoder. What was that about primitive?

Whether by manual means or by using the K3 utility, as soon as I hit tune (maybe a second later) the whole shootin match shuts down. The swr must go up too high. I've got it tapped into an MFJ-250 versaload. The old gallon can and the oil level is up there. It just isn't calibrating. It doesn't like something when it gets a whif of 50 watts.

Short only the ring to the shell - do you hear dahs? If both the above check are correct, there is no K3 problem - check your paddles and the cable.

Good Evening, Winter has returned to Oregon. Cloudy skies with rain. Freezing every night. But sun every week for at least an hour or two. Luckily for me this winter has been very mild. All the wood I collected last summer and fall is lasting quite well. I will have some left over for next year at this rate. I thought it was going to be a tough winter when the roads were blocked with 15 inches of very dry snow for Thanksgiving. However, by the middle of December all the snowing for the season had finished. Unless something major comes along between now and March I'll have many cords of wood left for next year. Propagation has been less than optimal. I have been kicked off the air more than once this week due to poor conditions. Lots of noise and some fluttering. The sun has not been cooperating lately. Just checked SpaceWeather. The solar winds have been creating a lot of aurora so that may be the cause of our recent difficulties. The deer have moved back up the mountain. They are now roaming the backyard eating whatever they can find. The front yard is less green so I do not see them there.

Re: [Elecraft] Fwd: K3 Failed DSP Firmware Download
Craig, If you are able, try using a real serial port on a desktop computer if you are able - no adapter drivers to confuse the issue. I use a real serial port and have done many firmware upgrades. The only time I had a problem was when I pushed a button during the upgrade process (that was my error, not a K3 error). If you are confined to your laptop, make sure you have the correct and current drivers for your USB to serial adapter. The older Elecraft KUSB adapters used the prolific chipset, but the newer ones (ordered in the last 6 months or so) use the FTDI chipset which seems to be more stable. The older USB to serial adapters have had some problems with Vista and Win7, so if your OS is not WinXP, and you are using the older KUSB, you may want to purchase an FTDI based adapter. The K3 firmware has been loaded by many users, so that itself is not the likely problem. USB adapters and their drivers are the most common causes of failure. 73, Don W3FPR On 2/5/2011 9:28 PM, cr...@thephotoman.com wrote: Original Message Subject: K3 Failed DSP Firmware Download Date: Sat, 05 Feb 2011 18:21:05 -0800 From: cr...@thephotoman.comcr...@thephotoman.com To: elecraft@mailman.qth.net I hope someone can help me as I tried to update the firmware onto my K3 this afternoon.

Re: [Elecraft] Fwd: K3 Failed DSP Firmware Download
Don, I have trouble blaming the problem on the K3 when the real problem lies with the Operating System and properly operating drivers (or lack thereof) for the USB to serial adapters. Use of a desktop computer for the hamshack is quite desirable IMHO - mine sits under the desk and the monitor, keyboard and mouse takes up less space than a laptop. If the particular desktop does not come with serial ports, there are cards available that will add native serial ports to a desktop. Laptops are quite another story, although PCMCIA serial port cards are available and should be more reliable than USB to serial adapters. Desktop computers with serial ports are available at bargain prices in the off-lease category (I like the IBM off-lease, many of which have 2 serial ports). Most are loaded with WinXPpro and cost less than $150, and are more than adequate for a dedicated ham-station computer. Sure, you have to spend additional dollars for a monitor, but that is small change compared to laptop prices. The flexibility offered by a desktop far exceeds the convenience of a laptop for ham use, and is much more reliable (a laptop is a throw-away device if it stops working). 73, Don W3FPR On 2/5/2011 9:49 PM, don Swetzig wrote: I needed to make a real rs232 cable to get mine to worknbsp; The usb adaptors don't work very well including the ones elecraft sell.

It looks a lot like an Ameritron inside. At most it looks like a EB104 CCI amp with a power supply and a low pass filter board in a box. The cooling looks to be primitive at best. I also dont like the switch mode power supply being so close to the high pass filter board. This is a recipe for noise and other problems. There is also a general lack of shielding. This might be ok for for 500 watt amplifier, however its very öpen I dont see real value in this amp especially after looking inside it. I would be more inclined to go buy an Ameritron AlS1300 which represents good value and has similar or better construction. It would certainly have better overhead in terms of output power. 73 John --- On Sat, 2/5/11, juergen plebia...@yahoo.com wrote: From: juergen plebia...@yahoo.com Subject: Re: [Elecraft] KPA 500 To: elecraft@mailman.qth.net, Albert Crespo f5...@orange.fr Date: Saturday, February 5, 2011, 3:33 PM Hi Albert The old standard of 220,230,240 volts +- 10% has been gradually deteriorating to plus minus anything! The mains voltages in many places now goes up to and regularly runs at 260 volts! The global de-regulation and privatization of power assets globally has seen standards go down the drain everywhere. Most quality switch mode power supplies are designed for voltages as high as 260 high volts with a plus 5% rating. Many designers and export countries have not caught up with the global deregulation of mains voltage standards. In many places this has been allowed to happen in the hope that a global standard will develop. I can buy energy saving globes that are rated to work at 260 volts(Philips). Many TV's from the Korean companies are designed to work at 260 volts. There is still a lot of new equipment designed for either 220 and 230 volts nominally. This well defined standard is hardly the reality anywhere these days even with the +- 5% allowance The Tokyo high power amp looks interesting. They appear to be using VRF150's. If they have biased this amp very well they will achieve good IMD results. SPE amplifiers using the MRF150's dont achieve the best IMD performance which can be obtained from these devices. The Yaesu FT-5000's PA appears to be very well designed. The 3rd order IMD figures in Class AB according to the reviews are almost as low as Class A at 200 watts of output. They use VRF150's This a is a very good achievement by Yaesu and is a benchmark in terms of IMD performance. I doubt that the Tokyo High power will achieve such good results because THP have always used just the bare minimum bias on all their amp designs. IMD optimization has never been a design goal of theirs. I had a good chat with the designer one day and he was open and candid about this issue. Mt homebrew MRF150-EB104 amp easily achieves -40db 3rd IMD figures on all bands. My surplus ERB MRI amplifier which I bought on Ebay does even better than -40db 3rd order. These are all below one of 2 tone figures not PEP figures. The Elecraft KPA500 will use VRF2933's for which no IMD data is provided on the data sheets. I dont know why Microsemi leaves out this important data. Macom religiously supplies extensive IMD data versus bias current which makes choosing devices very easy. Anyway this will hardly be concern for anyone since the radios always have worst IMD performance than the amplifiers. I will watch the reviews and see how they both perform, the market is getting crowded! I will make my donation once I know how well they perform. It would be nice owning a compact 500 watt amp that performs well without all the mess and surplus rubbish hanging off the amp. 73 John --- On Sat, 2/5/11, Albert Crespo f5...@orange.fr wrote: From: Albert Crespo f5...@orange.fr Subject: [Elecraft] KPA 500 To: elecraft@mailman.qth.net Date: Saturday, February 5, 2011, 9:43 AM Tokyo High Power has produced a 600 watt amplifier, HL-550FX , http://www.arraysolutions.com/Products/THPtop.htm that can handle a wide range of voltages, so it is ideal for places with bad voltage regulation.

Re: [Elecraft] Fwd: K3 Failed DSP Firmware Download
Craig, I am glad to hear you had success. Unfortunately, many of similar problems are OS and USB to serial driver related. The USB cable itself is not the problem, but the available drivers to support it for the various OS versions seems to be the biggest problem. From my recall, the older KUSB with the prolific chipset is problematic with Vista and Win7 OS because Prolific does not have current drivers for those OS. Is this a Microsoft problem or is it a prolific chipset problem - I am not to be a judge, but it is a problem for the end user. There is no clear indication of who to point the blame finger toward. Buyer Beware - real serial ports seem to cause few difficulties. If you have a choice, use the native PC serial port rather than the USB to serial adapter. 73, Don W3FPR On 2/5/2011 10:54 PM, cr...@thephotoman.com wrote: Thanks for the input, Don.

David You can download the application from www.remoterig.com. Without a USB key you will not get it going but it will demonstrate the problem. The problem is that the remoterig ports have nothing to connect to until their application is actually running so anyone that polls their virtual ports will simply hang. Probably the best and fastest solution is simply allow your user to select a comport rather than you trying to help by polling for a W2, the remote rig people could also help by modifying their virtual port drivers.

Re: [Elecraft] P3 noise floor base line question.
That sounds about right. With the preamp on the K3 is more sensitive so the noise level drops. With the attenuator on the K3 is less sensitive so the noise level rises. Another way to look at it is to realize that the P3 compensates for the K3 attenuator and preamp to keep signal levels the same. So when you turn on the preamp, the P3 lowers its gain so that signals show at the same S level. That makes the noise look lower. Alan N1AL K3+P3. when the K3 is set up into a dummy load, with the pre amp OFF. the noise base line is at S1/2 (between S0 S1) on the P3.
