[Elecraft] Any good/clear How To docs on adding the N1MM+ software for Winkey usb smt to my k3+p3 station for windows 7?
The K3 build went nicely, no errors; same for the P3. Now just built Winkey usb smt to go with N1MM+ to add to the station for contesting. The keyer kit itself is working just fine as standalone keyer into K3. However, I'm finding the documentation for integrating N1MM+ the my Dell system 7.0 and keyer with the K3/P3 a bit much. Here I mean integrating the N1MM+ software with the above. I'd describe the docs as circular. I'm going in circles. I think I have the hardware hooked up right; that is, the Dell recognizes the serial ports, the USB and COM. What's of question is the setup/config of the software for SO2V. 73! and am age 73, hi, W0XI --- This email has been checked for viruses by Avast antivirus software. http://www.avast.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] Seperate Receive Antenna
Mike, I am using it with 2 loops, which are mounted at a 90 degree angle with respect to eachother. This allows me to switch direction, which is most pronounced on 160m and medium wave. The loops themselves are square rather than round (as recommended by LZ1AQ) due to mechanical constraints, furthermore each loop actually consists out of 2 loops in parallel to lower the inductance. I hardly use the dipole mode, since that almost always results in a much higher noise floor due to man made noise at my QTH. Jim, David, Regarding differential inputs, I concur with David that the diagrams published on http://active-antenna.eu/amplifier-kit/technical-documentation/ suggest that the amplifier has a differential input, so not sure which schematic you refer to Jim? 73, Wouter Jan PE4WJ On Mon, Feb 2, 2015 at 5:59 AM, jim jbol...@outlook.com wrote: There was a schematic published by LZ1AQ that showed the implementation of a loop required that one of the inputs of the amp was referenced to ground.

This can have significant issues as it relates to common mode noise. As a result of my research, I ended up with a Pixel loop. The amp has great characteristics, differential input, uses an A.C. wallwart for low noise, and the install instructions isolate the amp from any ground. The loop interface also has a control line input from your rig, that controls an internal relay, so the amp is protected when you transmit. The loop was designed by hams. The mechanical design of the loop is excellent, using welds at the aluminum joints. I have no interest in the Pixel company, just a very satisfied customer. So satisfied, I bought two of them and phase them with a DX Engineering NCC-1 phaser.

The N1MM+ install is pretty straightforward, and usually goes pretty easily. You must first do the basic install, then reboot and install the latest version. When you start N1MM+, it will ask for your call, name, and other vital info. Once that's done, go to Config Tab, select the top option, and plug in the info for what serial port your rig is on. If you're using a USB to serial converter, you'll have to use Control Panel to figure out what serial port it is on. You will also need to know what serial port the WinKey has been assigned to. Go to this link, click on Documents, then study Getting Started. http://n1mm.hamdocs.com/tiki-index.php?page=Document+Home As with any serial control, make sure that the computer and the radio are set to the same Baud Rate (Long Push Menu on the K3, Configure for the port in N1MM+). 38400 is the best choice. N1MM+ is very user friendly, very well written.

[Elecraft] KX1: I Killed My Rig
While doing some rework, a hot lead fell out of my hand and dropped on the board. A few segments on the display lit up briefly and then an eerie silence. Except for the little map light, nothing works. I've checked the DC voltages on the IC's and voltage regulators and the only voltages I can find out of limit are on U1: pin 7:0 and should be 1.4 pin 23: .3 and should be 4.9 pin 25: .5 and should be 5.0 It would appear that the MCU is blown although I can't quite see how these pins could keep the display from working. The hot lead dropped down in the physical between the 3 blue buttons and the MCU. I've verified that the xtal oscillator that drives the MCU is running. Before I order a new MCU, are there any other components that I might have blown due to carelessness that I can check? 72, Clark/WU4B -- View this message in context: http://elecraft.365791.n2.nabble.com/KX1-I-Killed-My-Rig-tp7597836.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

Re: [Elecraft] OT: K3 and Johnson Matchbox
Great group! I'd like the readers of this reflector to know that I received several replies to my post, with 12 pictures, and most impressive; three others volunteered to remove the case from their tuners to photograph the coils for me. That is a tedious job. K3KO suggested that some people would move a tap for the 30 meter band and I could test for it without removing the case. Per his suggestion, I had a 200 ohm 10 watt resistor and tied it across the output of the tuner and tested the 40 and 20 meter band for matching to a 1:1. It was fine. My first Matchbox (years ago) matched open wire like a slam dunk. This one is different, but so is the antenna. So, I needed to verify.

SWR with the AT in bypass is 1.3 on 80M, 1.2 on 160M. All this on ANT1. Power out on 40M up is as expected. I connected a dummy load to ANT2, and while screwing the connector on, there was a huge jump in the volume level on the 2nd receiver. The selected antenna is still ANT1.

Re: [Elecraft] KX1: I Killed My Rig
Clark, U1 pin 7 is the VSMTR signal and the voltage source comes from the product detector U5 pin 2. Either the product detector is damaged or U1 pin 7 has a shorted input. To check which, remove U1 and bend pin 7 out a bit, then plug it back into the socket with pin 7 hanging on the outside. If U5 pin 2 (and pin 1) are then at 1.4 volts, U5 is likely OK. U1 pins 21 through 28 drive the display directly, so that is why the display is garbage.

Re: [Elecraft] P3 beta software - Span Step NOT sticky
Andy Mike, The Step Span in not remembered through a power cycle on my P3. I have different REF LVL adjustments for each band on my P3 and they stay that way through band changes and through power cycles. I power my P3 from the K3 and I do not use the P3 power button. Could that be a factor in Mike's loss of REF LVL data? 73, Mike K2MK Michael Eberle wrote Yes, I noticed the Step Span on mine seemed to reset after a power cycle.

Re: [Elecraft] Seperate Receive Antenna
Thanks, Jim, that's opened out the discussion very well for me. I am not able to determine how bad this makes the performance, since the output is floating and I think hardly susceptible to common mode problems. I'm in the market for such antennas but most are outside my budget. I would like to have 2 loops (could be large loops) a half wavelength apart for diversity reception on 160 and this system with its delay line might do that economically. 2 amplified receive aerials (eg from CCW here in UK) with a phasing box would also be economical. The next on my list is the shared apex. thanks again for the link 73 David G3UNA Subject: RE: [Elecraft] Seperate Receive Antenna Dave, Here is the quote from W8JI Start quote 10-29-2011, 05:36 PM #8 W8JI Quote Originally Posted by WV6U View Post Here is one broadband RX loop design that I found very interesting and something worth trying out.

Re: [Elecraft] P3 beta software - Span Step NOT sticky
I just checked on a newly upgraded P3/SVGA and stepped span is remembered through a power cycle. (I also checked the code just to be sure). If I turn on stepped span and then power cycle the unit and press the SPAN key, the span is in stepped mode. If I press a key that I assigned to stepped span, it shows OFF when I press it, which means it was previously on. The P3 (and PX3) save values to non-volatile memory when the data is changed. In other words while you are adjusting it and not when the power switch is pressed, so it doesn't matter if you pull the plug or push the button to power it off. -Paul -- View this message in context: http://elecraft.365791.n2.nabble.com/P3-beta-software-Span-Step-NOT-sticky-tp7597820p7597829.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
Re: [Elecraft] Seperate Receive Antenna
David, Not sure what ur budget is. The amp in the Pixel is a Cliffton Labs design, using the Norton architecture. Jack of Cliffton labs cannot share info of the amp design, as he is under non-disclosure. He does sell a great amp, using the Norton structure, that has a gain ~ 50% of the gain of the Pixel amp. The Pixel amp and his for sale amp use the exact architecture. The interface to the amp is also well thought out. The amp is protected if you hook up a signal that goes low when the xmitter is keyed. It removes power from the loop. Take a look at Dallas Lankford's page on Yahoo groups. He has done A LOT of work in the area of low noise antennas and loops with amplifiers, and has some GREAT articles on that Yahoo group page. He discusses how to use the Cliffton amp with loops with good results. I just went and bought a Pixel, as I did not want yet another project to get 75% done and then sit. Dallas Lankford is a great resource for BCBDX and loops/low noise antennas. Also, if you mind the gap and account for common mode, the LZ1AQ amp would work. Again, just take note of potential CM issues.
