Re: [Elecraft] K3 phone plug
Hi John, Are you sure your external speaker is plugged in to the speaker jack and not the rear headphone jack? 73, Mike K2MK John McBee-2 wrote Problem still exist, however I have discovered that if I turn on spkr+ph to on, I have audio fine without headphones plugged in, but if I change it to spkr+ph to NO then the audio in speaker shuts off with no headphones plugged in. I have sprayed my phone connector plug with Eledtronic cleaner and put in phone jack and turned it and still no audio out speaker with phone plug out. When I turned on my K3 this evening before doing the test, I could not get any audio out speaker at all. Before it was hit and miss. So question again, cud it be phone plug on the K3 or firmware issue? Firmware agn is MCU 4.86.

[Elecraft] Yamaha CM500 Headset and Heil Adaptor
Recently purchased a Yamaha CM500 headset with a Heil AD-1-K headset adaptor for Kenwood (the red one). I love the headset, much cheaper than the Heil and performs about the same, IMHO. The only way I managed to get the mic to work was through the rear jack (yes, the mic was selected to front panel). I did read in previous threads referring to mono and stereo mic connection. Do I need to replace the stereo mic connector on the headset with a mono? Is there a trick with the adaptor or am I messing up the set-up? 73 de Bruce, N7TY White Plains, MD __ 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] Yamaha CM500 Headset and Heil Adaptor
Bruce, Unless Heil has changed the Kenwood adapter, it should work fine. Test your adapter - put a bare stereo plug into the adapter and use your DMM. Pin 1 should connect to the tip of the stereo plug. The shell of the stereo plug should connect to either pin 7 or pin 8 (or both) and the ring of the stereo plug should connect to either nothing or to pin 1 (but *not* connect to either pin 7 or pin 8). If those tests are OK, it should work - set the Mic Sel menu to FPL.bias and adjust the mic gain to indicate 5 to 7 bars on the ALC meter. 73, Don W3FPR On 12/24/2014 5:36 AM, Bruce Gab wrote: Recently purchased a Yamaha CM500 headset with a Heil AD-1-K headset adaptor for Kenwood (the red one).

Re: [Elecraft] Yamaha CM500 Headset and Heil Adaptor
Remove the adapter, plug in the headset to the rear connectors, select the MAIN:MIC SEL menu, press [1], press [2] and you're almost done. (Mic rear panel, Low Z, Bias On) Now, you need to set the equalization. I get unsolicited good audio reports with the following: Band 1: -16 Band 2: -10 Band 3: -4 Band 4: 0 Band 5: 0 Band 6: 0 Band 7: 0 Band 8: -6 You will have to tailor this to your voice and preference.

Re: [Elecraft] XV144 transverter problem
I think this condition occurs because, in my case, I am running quite high power, and it occurs if I slip back to receive while still talking. That is, being a little too quick to return to receive. I had the problem with my previous XV144 too. I have carried out the Q7 0.1uF capacitor mod as recommended by Don and, after a little testing, the problem appears to have gone. I have also lost the strange output indication that I got when there was no 144MHz output for now, although I don't think that can be related. I expect, like all these things, it will return at a crucial moment in a contest when I'm trying to work a weak multiplier! Thanks Don and Season's Greetings!

It should not be possible to create an overload situation with 1 mW of drive, although it may be possible to create an overload indication if the XV144 is in receive and it senses an RF input. First check the jumper on the front panel board near the firmware IC. The jumper block should either be off or plugged onto only 1 pin. Most likely, it is a false overload indication caused by noise pickup on the front panel COR circuit. Remove the front panel metalwork (the board can stay connected to the RF board) and find Q7. Solder a 0.1uF capacitor between the collector and emitter of Q7. That bypasses the noise and prevents a false indication. 73, Don W3FPR On 12/18/2014 2:12 PM, Jeff Uchitjil wrote: I just completed my XV144 and everything seems to work with it it, except it seems to randomly trip a relay in it for a split second.

Re: [Elecraft] KPA1000
Another consideration for a KPA1000, would be the almost certain need for 220V power. Fine and dandy if it's already in the shack, but certainly an extra cost. Sure, you can run a 1KW room heater from 110V... so what if the line voltage sags to 100V on that circuit.. the heater will just deliver a bit less heat. Or my vacuum cleaner (which draws 12 A) works fine on about 110V. But, a linear amp will want to see a pretty stiff power supply to maintain linearity. 500 W is pretty much OK on household 110 V branch circuits. And, as others have pointed out... the whole amp with power supply fits into a K3 sized case. Pretty slick engineering, I say.

Re: [Elecraft] KPA1000
The need for 220 VAC is a very good point, Ray. Operating from 110 VAC has always been a constraint for me, and likely for many of us. Of course, I'm less serious than some hams -- and since the mid 90s QRP has been a focus of mine. I sure do like having the KPA/KAT500 duo and the ability to kick it on line by simply pressing the Operate button. My last amp, an AL-811H, was far more work to use and got little use as a result. 73, Phil W7OX On 12/24/14 8:00 AM, Ray Sills wrote: Another consideration for a KPA1000, would be the almost certain need for 220V power.

Re: [Elecraft] K3/O-Mini + Remote Rig Configuration for Heil Headset
Barry, I cannot comment on the RemoteRig setup because I do not have any experience with it. There are some statements that may require clarification - I think the Heil document is somewhat confusing. 1) For a dynamic microphone, turn bias off. 2) The K3 (and K3/0 and mini) can turn bias on or off - so it is not dependent on electret microphones such as the Elecraft MH2. The choice of bias or not is a user choice in the menu. 3) The Heil microphone elements are relatively low output. 4) The K3 microphone L or H selection determines the gain of the microphone preamp. L is low amplification, and H is higher amplification. With Heil microphones, you may have to use the H setting. 5) Try the H setting with bias off in the menu and see if you can get the required 5 to 7 bars on the ALC meter. 73, Don W3FPR On 12/24/2014 1:30 AM, Barry Baines wrote: I am having difficulties getting my Heil ProSet with the HC-4/HC-5 mic cartridge to work with the K3/O-Mini + RemoteRig (purchased from Elecraft) where there is no audio reaching the K3 at the radio site.

[Elecraft] 240V Line
Installing a 240V outlet is not a big deal unless the construction of your home makes it difficult to run the cable. Barring that, a competent electrician should be able to do that in a half day; a difficult run could double the work. All that is required is a pair plus a Green wire. If you also want 120V outlets from the same circuit, you'll need another conductor for the neutral. A single 20A 120/240V circuit will run all the ham gear in most stations, even for SO2R. If you're smart, you'll use #10 copper, 20A outlets, and a 20A breaker. While #10 is rated for 30A, our stations don't need 30A, but the bigger copper will reduce the voltage drop. There are MAJOR advantages to running all the gear in our stations from outlets that share the same Green wire, or outlets whose Green wires are bonded together.

And, some homeowner associations may have rules that require the use of a licensed electrician, particularly in condo and townhouse communities, where your unit is sharing a wall with other owners. And, that may not be a bad idea, because there are quite a few people who simply don't know what they are doing with electrical wiring.

Re: [Elecraft] 240V Line
It has been awhile since I have worked with the NEC but things haven't changed that much for single phase. It has never been allowed for the green/yellow lead to carry load current. Green and neutral must be the same size as the current carrier even on a 240 circuit. Green and neutral may not be circuit breakered. A 240 circuit may only be split (down to 120) at a panel or sub panel and then each circuit must have its own circuit breaker. 120 volt circuits must have special plugs and sockets if breakered for at more than 20 Amp. Panels or sub panels may not be placed in closets or closely enclosed areas. (This is to avoid heat buildup.) Some areas are requiring arc detecting or GFI interrupters on upgrades. If you install them (generally a good idea) then place GFI/ARC type circuit breakers at the panel. Do not place at load where RFI is likely to false trip. As warned local requirements may vary but this is sort of baseline stuff. Nobody will fault you if you follow. 73 Fred, AE6QL -Original Message- From: Elecraft [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Jim Brown Sent: Wednesday, December 24, 2014 1:50 PM To: Reflector Elecraft Subject: Re: [Elecraft] 240V Line On Wed,12/24/2014 11:41 AM, Charlie T, K3ICH wrote: A lot of the older amps (Thunderbolt for example) had 120 V fans wired from one hot to ground.

[Elecraft] KPA500 Strange Operation
First, let me wish all a very Merry Christmas! OK, now the problem. I have a KX3 and the full K-line: K3, P3, KPA500, and KAT500. I have a two position coax switch that I use to drive the amp with either the K3 or the KX3. When using the K3 (P3 powered off) all works perfectly. I can change bands by pressing the appropriate band button on the amp or changing bands on the K3. Doing either results in the amp display changing to the associated band. But If I have the KX3 turned on and the K3 off, pressing a band button on the amp has no effect. The only way to change bands on the amp is to set the KX3 to the desired band and then tickle the amp with a little shot of RF. Now, the bad news. It does not do this all the time. Not 100% certain, but it seems to act like this if the amp has been powered off for a few hours. Just a couple minutes ago I was doing some sleuthing on this issue. After having the K3 online and sending RF, I tested this out and the amp subsequently behaved as it should after a K3 shutdown and KX3 startup. The amp changed bands with its own buttons or via RF from the KX3. Hmmm... Very strange. Anyone (K6KR?) able to shed light on this unusual behavior? Not a gigantic big deal, but it does make me wonder what's going on. 73, Jim Jim Bennett / W6JHB Folsom, CA __ 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] Our Christmas gift
This message may be a duplicate for some of you as it's being sent using several of our mailing lists. Most of you are aware that Rose has been treated for uterine cancer for the last seven months. This has included both chemotherapy and internal vaginal radiation. What makes this an especially nice Christmas is that all her treatments were completed this week, ending what has been the most difficult period in the nearly sixty years we've been married. The oncologists continue to tell us she's cancer free but aren't making any predictions about when she'll be back to normal, other than to say it will be several months. Her hair is starting to grow back and is about a half an inch long and dark grey. They say it will return to her normal color in a few weeks. She has several hats and caps ... they're actually stylish and cute. (:-)) We don't know future details yet ... the next meeting will be on January 14th for follow-up checks, CT scan, etc. She'll be monitored for five years. Her attitude through all this has been really positive. She's shown her strength and I'm very proud of her. The staff at the Community Cancer Center in Missoula has been wonderful. We're very fortunate and hope your family's Christmas is as happy as ours.

Re: [Elecraft] KPA500 Strange Operation
The KPA500 is my work, so I’ll try to answer… See discussion below. On Dec 24, 2014, at 9:22 PM, James Bennett w6...@me.com wrote: First, let me wish all a very Merry Christmas! And from the W6FB family as well! OK, now the problem. I have a KX3 and the full K-line: K3, P3, KPA500, and KAT500.

I can change bands by pressing the appropriate band button on the amp or changing bands on the K3. Doing either results in the amp display changing to the associated band. When the KPA500 is set for RADIO = K3 and the K3 is on, this is the correct behavior. Pressing a band button sends the button info to the K3 using the Auxbus serial communications. The K3 responds by changing bands, then the KPA responds to the BAND lines change by changing bands itself. Note that the button push on the KPA only causes a command to be sent to the radio, it does not directly cause a band change in the KPA500. The behavior is different for all other RADIO settings. In those cases pushing a band button causes the KPA to change bands. The next thing to realize is that when RF is sensed by the KPA, it will change to the frequency counted band, even if other methods have told it to go to a different band. Of course if the counted band is the same as the previous band change, there will be no further change. Hopefully this is a lot clearer than mud… Also note that powering on or off the P3 has no effect on the KPA500. The K3 must be powered on for the KPA500 integration to work, and must be powered off completely for the KPA500 to mostly ignore it (see BAND discussion below). But If I have the KX3 turned on and the K3 off, pressing a band button on the amp has no effect. This behaves exactly as described above. The KX3 does not have Auxbus, so it will not receive the button command from the KPA500 and thus nothing will result. The only way to change bands on the amp is to set the KX3 to the desired band and then tickle the amp with a little shot of RF. As expected. Note that the K3 better be completely off when this happens, or _it_ will respond to the button press, change bands, and cause the KPA to do something. Also note that the K3 has pull-up resistors on its BAND lines, causing the signals to be pulled to the +5V rail when they are not being driven low. A short time after the K3 is powered off, the +5V rail will drop to 0V. The pull-ups will continue to do their job, pulling the lines to 0, which tells the KPA to change to 60 meters. Now, the bad news. It does not do this all the time. Not 100% certain, but it seems to act like this if the amp has been powered off for a few hours. Just a couple minutes ago I was doing some sleuthing on this issue. After having the K3 online and sending RF, I tested this out and the amp subsequently behaved as it should after a K3 shutdown and KX3 startup. The amp changed bands with its own buttons or via RF from the KX3. Hmmm… Exactly how do you have the K3 and KX3 connected to the KPA500? The K3 loads the BAND lines at all times (and some other AUX signals), even when it is powered off. A change in the BAND lines is required to cause the KPA500 to change bands - if they remain stable then no band change will result. This means that after the K3 powers off and the +5V rail goes to zero, there should be just one band change (when the lines drop). After that any band changes will be due to RF. Do you have some other connection to the BAND lines besides those from the K3? By far, the best way to connect two radios to the KPA500 is to use a switch that disconnects the AUX cable from the K3 before attaching AUX signals to the other radio. Many have noted that you can generally get away with keeping the K3 connected to the KPA500, but results cannot be guaranteed. You might want to change the RADIO settings to something else (try SERIAL) when using the KX3 - with no band change reports coming in the KPA will rely solely on the RF sensing. But, give me a complete description of the setup and I’ll be able to better analyze the situation. Also, what version firmware is in the KPA500? The latest is V1.38, which is very highly recommended. The K3/KPA500 integration code did see several changes in the 1.30 - 1.38 time frame. Very strange. Anyone (K6KR?) able to shed light on this unusual behavior? Not a gigantic big deal, but it does make me wonder what's going on. Dick did a great job with the KXPA and KAT500, while the KPA500 is mine. So many developers, so little time... 73!

Re: [Elecraft] KPA500 Strange Operation
Jack - good evening (or maybe good morning!). Great info and thanks for the quick response. I have my setup exactly as in Fred Cady's KX3 book, towards the end of the book. He has a great diagram showing how to run a KPA500 from a K3 or KX3. Do you have his book? If not I'll respond and tell you what I've got. Also, yes - I have current f/w levels on all my equipment. And your other item, yep - I'm always careful to have the other radio completely powered off before doing anything with either. 73 - time for Santa to start hauling presents from the attic to the Christmas tree - the two boys are finally asleep in their rooms!

I have a KX3 and the full K-line: K3, P3, KPA500, and KAT500. I have a two position coax switch that I use to drive the amp with either the K3 or the KX3. When using the K3 (P3 powered off) all works perfectly. I can change bands by pressing the appropriate band button on the amp or changing bands on the K3. Doing either results in the amp display changing to the associated band. When the KPA500 is set for RADIO = K3 and the K3 is on, this is the correct behavior. Pressing a band button sends the button info to the K3 using the Auxbus serial communications. The K3 responds by changing bands, then the KPA responds to the BAND lines change by changing bands itself. Note that the button push on the KPA only causes a command to be sent to the radio, it does not directly cause a band change in the KPA500. The behavior is different for all other RADIO settings. In those cases pushing a band button causes the KPA to change bands. The next thing to realize is that when RF is sensed by the KPA, it will change to the frequency counted band, even if other methods have told it to go to a different band.
