[Elecraft] KX3-> KXPA100=> KPA500 ... Can it be done?
Looking for a little QRO in my alternate station... I would like to be able to run my KX3 into my KXPA100 amplifier, and that into my KPA500 amp. How do I do that?

Re: [Elecraft] KPA500 strange response
How did you determine that the cables seem "fine". Did you do a continuity measurement on each pin? Did you check for shorts between adjacent pins. If selecting 12 meters on the K3 produces 6 meters on the KPA500, then there may be something awry with the BAND1 data output from the K3 to the KPA100. That is pin 3 of the cable. 73, Don W3FPR On 8/3/2016 8:12 PM, Harlan Sherriff wrote: Both cables seem ok. Also, if I select 12m on K3, the KPA goes to 6m.

[Elecraft] K1 tilt stand bail- how to make
This is from my own personal 'wayback' records source not evident to me with short notice. Alt #2 - "The Never Fail Cheap & Dirty K1 Bail"; (with apologies to Tom, =N0SS, and his probe) Take a piece of 15" long by 3/32 - 1/8" diameter sol=id wire (a heavy duty coat hanger works great!). Slide two 1/2" X 1/8" ID=vacuum hose (any auto parts store) to the middle of the wire. Starting f=rom the middle measure 2-5/8" each way and bend 90 degrees. You now have =a square "U", with the base measuring 5-1/4". From the corners of the "U"=measure 3-1/2" and bend 90 degrees so that if the "U" is sitting on a ta=ble the two bends you just made would stick straight UP from the table. N=ow, measure from those just completed bends 1-1/4" and make a 90 degree b=end such that the ends of the wire are now facing each other. Clip the en=ds of the wire about 3/8" away from the just completed bends. These littl=e stubs will fit into the screw holes on the K1 that are designed for the=tilt stand. When you first complete this stand take the top cover off to=ensure that there are no interf erence's with the KNB1 or the KBT1 when t=he stand is installed. Trim accordingly. Slide the two rubber hose pieces=to the corners. These will act as the feet of the stand. This compact stand can be flipped beneath the radio and the bottom of the=bail can snapped against the rear of the radio and beneath the antenna j=ack for stowage. To use simply flip the stand forward and use a rubberban=d mounted three-quarters the way up the parallel arms to secure the radio=at the desired viewing angle. __ 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] KX2 - updating firmware
Pete, Fine that you are using an FTDI USB to serial adapter - but what is the connection from the DE-9 conncetor on that adapter to the KX2. If it is the KXSERa cable, then it should work fine, but if you have wired your own DE-9 to 3.5mm cable, then check it to make certain it has the correct connections and has continuity on all 3 of the used conductors. In other words, if you have made your own Serial to KX2 cable, check it first. Set the KX2 RS-232 to 38400 and use KX2 Utility to attempt to connect. 73, Don W3FPR On 8/3/2016 5:18 PM, Pete Jones wrote: I am using an FTDI cable (not Elecraft KXUSB).

A 1500 watt amplifier is not going to make you a better operator. Many amps today that are being produced over seas have tetrode finals that will put out 2500 watts easily, check your coax at the frequency that you want to run and you may be in for a surprise. If you swr is greater than near unity, you may have problems with the reflected power melting down the foam by heat and creating more loss. With an amp you have to have resonant antennas, you don't want RF in the shack. And at that power level antenna tuners become a very effective Ozone generator, keeps you shack smelling nice and fresh but it does not do much for your finals and spark gap was outlawed quite some time back. I have a 1.2 kw amp and run it at 450 to 500 watts, why, because it puts me in a contest class that I can be competitive in because I don't have 6 towers with stacked beams.

The cheapest way to communicate with less power is painful for some, but the truth is always painful when you take the easy way out.

I strongly suggest that you correct the cause of this rather than spending big money on a noise cancelling headset. Have you communicated with Elecraft about this? My KPA500 fan runs at high speed ONLY during long keydown transmissions (like JT65, for 50 seconds, then 70 seconds off) and when "beacon-CQing" on 6M (efficiency is lowest on 6M, so heating is greatest). It's hard to imagine this being a problem below 15M unless you're making very long transmissions. Will this work with the K3S. I see no reason why not. Bose says EMI /EMC should be ok for HF. I don't know -- RFI to the shack tends to be greater if TX antenna is close to the shack, especially with an end-fed antenna that terminates in the shack. I understand DC Bias 8V is no problem. Right. How about the Stereo 320 Ohm Earphone impedance and the K3S recommended 16 Ohm min ? 320 ohms is >> 16 ohms, so no problem. How should the electret mike be configured Bias through 220 to 2200 Ohm?

[Elecraft] (no subject)
Since Elecraft has (repeatedly) stated no KPA1500 is to be made, then consider other sources. I suggest if you want to save money to consider a W6PQL amp: http://www.w6pql.com/1_kw_sspa_for_1_8-54_mhz.htm Note the pic of a KX3 at beginning of article. Great kit if you are so disposed; I believe also available assembled and tested from W6PQL My only relationship is having used several of his kits in my personal station and the 2m 80w pc board in the 2M80 linear I sell. Jim is very helpful in several technical conversations I have had with him. Some day I would like to acquire his 2m 1200w PA module as basis for replacement of my 8877+HV supply. It could be remotely installed in a wx-proof compartment at the base of my 2m tower, eliminating expensive low-loss coax run from the shack (and get the durn blower noise out of the shack). These LDMOS drive with 3-10w. 73, Ed - KL7UW From:To: Subject: [Elecraft] KPA500 Amplifier Combiner Message-ID: <005901d1ed2f$646e6fa0$2d4b4ee0$@com> Content-Type: text/plain; charset="us-ascii" It does not make financial sense to combine two or three KPA500s using a commercial combiner that costs thousands of dollars. SPE Expert makes a two amp combiner and Acom has one that will combine three amps. I believe that there are also some combiner boards available on eBay. The KPA500 is a very nice amp however if you really desire more power you are probably better off looking elsewhere, at least until the KPA1500 becomes available :) John KK9A 73, Ed - KL7UW http://www.kl7uw.com "Kits made by KL7UW" Dubus Mag business: dubus...@gmail.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] Where is the K3s setup for JT65 info?
Ken, I am using the USB interface to the computer and am having trouble figuring out how to set the audio levels for WSJT-X: -On receive the decoder is saturated. I have to drop the gain slider in WSJT-X to zero to be able to decode any signals. I haven't found any other adjustment for the level. -On transmit in Data A mode, the mic gain selects a Line x value. I didn't see that anywhere in the manuals. Do you select a Line value that gets you close and fine tune the level with the gain control in Windows?

Re: [Elecraft] K3S with Internal ATU(KAT3A) and Remote ATU?
I have a K3 without the internal ATU and use a MFJ-927 remote tuner for my ZS6BKW inverted V. I also have a manual tuner in the shack which is usually in bypass, just monitoring power out and incoming SWR. There some parts of 40m where the MFJ-927 doesn't get a good match and I touch it up with the manual tuner to keep the K3 happy. I don't see why you couldn't take a similar approach with the KAT3A. The MFJ-927 is a finicky beast but it has served me well for over 4 years. I don't think it uses latching relays so you have to keep it powered to use it. I could be wrong.

[Elecraft] KX2 - Dimension of the KXBT2 Li_Ion pack?
Dear KX2-users, I would like to know the dimension of the Li-Ion package: Height, width and length? How long is the power cable inclusive 2.1mm plug? As well I’am interested about the dimension of the space inside the KX2, which is reserved for the KXBT2 Lithium-ion Battery Pack. As far as I know, the package (11V, 2.6Ah) consists of three Lithium-Ion 18650 cylindrical cells with integrated security (PCB). I’am intend to order in Germany a pack of three 18650 cells with a capacity of 3400mA. To tell the dealer the specification, I need the dimension of the original KXBT2. thanks, Stephan, DD6DO __ 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] k3/0 Mini problem
GM All, I purchased and have installed a K3/0 using Remote Hams software. When I run the unit as a client, I have noticed that I am not able to use the 2nd receiver. It is absolutely quiet. I can point the transmit towards the frequency on the second receiver and it will transmit on that frequency. At the moment, it appears that in order to work split on a rare dx station, the configuration has to be reversed ie. DX station on main vfo and set the transmit frequency on some frequency in the dx station suggested listening bandwidth. Or have I missed something in the setup that would allow me to use the K3/0 Mini just like I would my home K3? I'm hoping that this is the case.

[Elecraft] K3S with Internal ATU(KAT3A) and Remote ATU?
I have a new K3S/100W with internal ATU (KAT3A) as well as KRX3A SubRX. My antennas are a 102ft G5RV at 40ft with LDG RC/RT-100 Remote ATU at base, and I’ll have a DXE-MBVE-5 43ft vertical with MFJ-927 Remote ATU at base after completing this weekend. A few questions: 1. How to best use the K3S internal ATU in conjunction with the Remote ATUs? Both can be used in Bypass mode, the K3S by command and the Remote ATUs by removing Bias-T voltage. The LDG rATU on the G5RV is “latched” in the last LC configuration before removing Bias-T voltage – still learning about MFJ-927. It seems that I might first put the K3S in Bypass, remote tune, and then if >2:1 SWR, remove voltage from Bias-T to “latch” the remote ATU, and then engage the K3S internal ATU to try and lower SWR to <2:1. Added loss, but maybe better than K3S power fold-back. But that’s where I need advice. 2. I’ll set up for “Diversity RX” when I figure which antenna should be my TX antenna, which might change based on band and direction (G5RV is N-S, and even at 40ft, reaches E-W better than N-S). In this case, I wonder if I could tune my SubRX “Diversity RX Antenna” with remote ATU for better reception? -- View this message in context: http://elecraft.365791.n2.nabble.com/K3S-with-Internal-ATU-KAT3A-and-Remote-ATU-tp7621137.html Sent from the Elecraft mailing list archive at Nabble.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
