[Elecraft] K2/100 Keying a Drake L-4B
Hi Elecrafters, I am ready to key my Drake L-4B using my K2/100 but I read from a previous post: If you already have the KPA100, look on the rear panel and you will see an RCA jack marked PA KEY OUT between the ground connection and the power connector - this will allow you to key your external amplifier directly - but only if your amplifier has a positive voltage for its keying line. If your amplifier uses a negative voltage keying circuit (like the Collins 30L-1 and some others) you will need to construct an external circuit to key the amp. 73 --don n4hh K2/100 #2028 Does the Drake use a negative voltage for the keying (line)? If it does what modification do I need. I installed the Soft-key mod made by Harbach. I am not sure whether that converts the Drake to positive voltage keying. Any help is appreciated.

Re: [Elecraft] K2/100 Keying a Drake L-4B
A simple way to find out is turn the amplifier on and measure the voltage on the keying input on the amplifier, noting the voltage and its polarity. Next switch your multimeter to measure current and connect it to the same place on the amplifier. The amplifier should key and you will see how much current needs to be switched by the radio. This procedure should work with any amplifier. 73 - Mike WA8BXN ---Original Message--- From: Ariel Jacala Date: 08/04/13 07:57:01 To: elecraft reflector Subject: [Elecraft] K2/100 Keying a Drake L-4B Hi Elecrafters, I am ready to key my Drake L-4B using my K2/100 but I read from a previous post: If you already have the KPA100, look on the rear panel and you will see an RCA jack marked PA KEY OUT between the ground connection and the power connector - this will allow you to key your external amplifier directly - but only if your amplifier has a positive voltage for its keying line.

Re: [Elecraft] K2/100 Keying a Drake L-4B
Ariel (and all), I don't know the specifics of that amplifier, but one can make a quick measurement to find the answer for yourself. Turn on the amplifier and measure the voltage at the amp's Keying input with your DMM. Is it positive or negative? How large is the voltage? If you are concerned about the keying current, set the DMM to measure current. The amplifier will key, and the meter will indicate the current that is developed. 73, Don W3FPR On 8/4/2013 7:56 AM, Ariel Jacala wrote: Hi Elecrafters, I am ready to key my Drake L-4B using my K2/100 but I read from a previous post: If you already have the KPA100, look on the rear panel and you will see an RCA jack marked PA KEY OUT between the ground connection and the power connector - this will allow you to key your external amplifier directly - but only if your amplifier has a positive voltage for its keying line.

[Elecraft] KAT500 vs K3 ATU
I am considering getting a KAT500 to provide me with higher power auto-tuning. Currently, the KAT3 is capable of achieving a match on all bands using my open-wire fed 160-meter dipole, with some help from a 4:1 balun. I believe both tuners are T-matches, but I don't have enough information to judge whether the KAT500 will achieve the same matches that the KAT3 will.

Re: [Elecraft] KAT500 vs K3 ATU
Gary, Both tuners are L-C or C-L with the cap being able to be on the transmit side or the antenna side. The L and C values can be found in the K3 schematic package available on the Elecraft website but, so far as I know, the KAT500 schematics haven't been published yet. I would expect, that if you K3 can tune the antenna, certainly the KAT500 can too.

Re: [Elecraft] KAT500 vs K3 ATU
Essentially the same lumped values of L and C and hence the same tuning range. The distributed reactances inside the larger tuner are somewhat different because of component size changes, so there are some minor differences that show up on 6 meters mostly. If you install the KAT500 Utility (available free on our web site), the individual KAT500 L and C values are shown on the Operate Page. You don't need the ATU to do this. Both tuners are switched L matches, with a series inductor and the ability to switch the selected capacitors to either end of the inductor. 73 de Dick, K6KR -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Gary Ferdinand Sent: Sunday, August 04, 2013 7:37 AM To: elecraft@mailman.qth.net Subject: [Elecraft] KAT500 vs K3 ATU I am considering getting a KAT500 to provide me with higher power auto-tuning.

[Elecraft] Elecraft CW Net Announcement
Good Morning, After a chilly week the temperatures are climbing back into the upper 60s again. It feels good not having to heat the house. Summer should be a time where I can work on my garden rather than carry wood. It was nice to receive some precipitation though since fire danger was rising. Hopefully we will get more rain between now and October. Propagation was great yesterday on 20 meters. Even with the sun as calm as it is now there are still ions flitting about. I scanned 15 and 18 meters yesterday and found they were both open. I was hearing well across the ocean into Asia. Lots of JAs and some Russian stations. Other, weaker stations, popped up now and then too. I keep trying 10 meters but have yet to hear anyone up there. I am not sure at which time of day this band opens.

Re: [Elecraft] K2 alignment and test part 2
Mike, The best use of the 'scope is during the transmit bandpass filter alignment - just connect the 'scope (with a 10X probe) across your dummy load, and use it to indicate the RF amplitude - that is faster then looking at the slower to change display on the K2. If you have the KAT2 option (or the KPA100), you can use the 'scope amplitude reading to calibrate the wattmeter for forward power. Use the peak to peak voltage and square it, then divide by 400 to give you the power (assuming your dummy load is a good one at 50 ohms pure resistive). Other than that, you will not have to use the 'scope much at all -- of course if you need to do some signal tracing, it is the best tool to use. Hint for that, multiply the 'Expected' RF voltages in the manual by 2.8 to give the expected peak to peak voltage. As far as frequency calibration, I would not believe the frequency counter in a 'scope would be sufficiently accurate for doing the dial calibration. You may want to defer the dial calibration until the last step after you have Part III done and then look at the K2 Dial Calibration article on my website www.w3fpr.com to set the 4 MHz reference accurately and achieve good dial calibration. For the filter alignment, use the information in part 3 of the dial calibration article for use of Spectrogram to get the best results. If you do not have a good copy of Spectrogram, look for the download links on my home page - near the bottom. The XG3 is excellent for setting the S-meter HI reading (CAL S HI) Yes, you can use it when doing the receive bandpass filter alignment. The K2 is designed to use minimal external equipment for the alignment and calibration. Most of the essential tools are built into the K2, and they work very well. 73, Don W3FPR On 8/4/2013 3:35 PM, Mike Weir wrote: In my K2 build I am approaching the alignment and test part 2 stage.

Re: [Elecraft] K2 alignment and test part 2
IF your scope is well calibrated you can use it for many d-c measurements as well. Whenever I'm adjusting a level for a peak or minimum reading, audio or dc, I prefer my scope instead of a DMM because the scope is instantaneous and provides an analogue (moving trace) instead of a digital readout, even though my DMM provides a bar indication below the numbers to emulate something approaching an analog display. Of course, the scope is ideal for such adjustments at RF as well as Don mentioned. Indeed, my scope gets used to provide me an analogue display for setting a signal level as much as any other use. If I could only have one piece of test equipment to troubleshoot something, it would be my 'scope. (Don't forget to convert the RMS values given for a-c measurements to peak-to-peak as Don mentioned.) One bane of digital displays is that they often provide a false sense of accuracy and lead the unwary into thinking their digital exactness is important or even desirable. It's almost never important to whether a voltage is 4.12V or a bit over 4 volts. I will confess to being one of the early adopters of digital watches decades ago, but I soon replaced it with a round faced pulsar. I had no interest in learning that it was 9:56 a.m. when all I wanted to know was that it was almost 10. 73, Ron AC7AC -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of VE3WDM Sent: Sunday, August 04, 2013 2:25 PM To: elecraft@mailman.qth.net Subject: Re: [Elecraft] K2 alignment and test part 2 Don thanks very much for taking the time to get back to me and I will use the scope for the procedures you indicated.

[Elecraft] KX3 Roofing filter questions
Hi, After installing the roofing filters in my KX3 (which was a while ago), it seemed to me that the received audio was down somewhat from the levels I recall from before the filters were installed. At the suggestion of another KX3 owner, I tried the following experiment: I hooked up my XG1 signal generator directly to the KX3. With the AGC turned off, in CW mode and the narrowest bandwith so that filter 3 was selected, and the XG1 at 50uv, I let the AFV indication stabilize, then noted the AF db was at 0.0db, Opening the PBT control until filter 2 clicked in, and the dbv jumped to +1.1db. I kept going until filter 1 clicked in, and the dbv jumped to +1.4db. I tried this sequence in both directions, both at 50uv and 1uv, and that ratio of 1.4 - 1.1 - 0.0 was repeatable at both signal levels. Is this normal for using the roofing filters?

Re: [Elecraft] posting of kx3 shacks and antennas.
I use one of the following antennas: 1. A home brew Carolina Windom for 40 up 35-40 feet. 2. An interlaced 40/20 meter delta loop, apex up, base ~6 feet over ground, and fed at a corner 3. An 18' vertical with 2 9' radials fed at the vertical base which is ~15' feet above ground. My shack is too messy to be photographed at this time. My Field Day operation is entirely different. I participate with a team of others who also own KX3s, except one. our antennas consist of beams and 1/2 rhombics. The towers are AB-577 portables.These are not for the average home shack. 73, Barry K3NDM - Original Message - From: Richard Neese kb3...@gmail.com To: elecraft@mailman.qth.net Sent: Sunday, August 4, 2013 4:09:23 PM Subject: [Elecraft] posting of kx3 shacks and antennas.
