Re: [Elecraft] How Accurate of 50-Ohm Dummy Load for 50 Watt TX Gain Calibration?
Thanks to Wayne, Tony, and Don for their answers to my question. I am going to use my DL-1 20-watt load and do the calibration manually and monitor the heating of the resistors (actually, I have a nice Fluke temperature measurement tool to do job if needed). 73, phil, K7PEH On Mar 28, 2015, at 5:37 PM, Wayne Burdick n...@elecraft.com wrote: Anything under 2:1 will allow the TX GAIN calibration to work, but I'd shot for 1.5:1.

Actually, my smaller 150 watt dummy load is closest with a range of 42 ohms on the load to about 55 ohms on the high end as I step through the frequency ranges of my Antenna analyzer. My 1500-watt dummy load is worse as the resistance goes up to 87 ohms Z (resistive plus reactive) with 54 MHz test signal (using MFJ 259 analyzer). My little Elecraft DL-1 20-watt dummy load (mini-module kit) is best as it is flat 50-ohms resistive across the entire HF spectrum. I am thinking of using and following the advice of Wayne to let it cool down between bands. But… If I want to let the dummy load cool down between bands then can this be done using the automated procedure with the K3 utility or do I have to run the manual procedure. In other words, does the automated procedure allow me to automate the process on a band by band basis. I have not tried it yet because I didn’t want to start something until I was ready to finish it (and I have not installed the latest firmware yet). Question: How accurate should the dummy load be — is an SWR of 1.2:1 and under good enough? Question: Does the K3 Utility allow me to perform the TX gain calibration on a band by band basis?

Re: [Elecraft] ESTATE SALE: K2 with options KPA100 +KAT100 in EC2 Enclosure
The frequency display alignment is easy enough to do, there is good information about this on the webpage of Don W3FPR: http://www.w3fpr.com/dial_cal.html I recommend the N6KR method which is linked on that page -- tune in WWV either zero-beating against a second AM shortwave receiver, or use spectrogram to see the frequency of the WWV tones, then use the N6KR method to align the VCO/BFO. With a bit of care, you can get the dial showing the right frequency to within 20Hz. 73, Matt VK2RQ On 29 Mar 2015, at 11:31 am, James kvochick jameskvoch...@me.com wrote: Estate radio for sale: K2 Transceiver (serial number in 58xx range) Transceiver includes: KSB2 SSB Module K160RX 160 Module KNB2 Noise Blanker KAF2 Audio Filter KAT2 20 Watt Tuner KIO2 Serial Port Kenwood Microphone Rework Modules KPA100 KAT100 (100 Watt Amplifier and 100 Watt Tuner) Built in an EC2 enclosure (includes serial cable to connect to K2 All manuals I’ve had the station on the air, and despite the frequency display being a little off (probably needs an alignment) everything seems to work great.

Re: [Elecraft] K3 - MCU/FPF/DSP1 Firmware Update Failure
Ken, Actually, since you have the P3 in place too, there are 5 possible points of failure instead of 3. To what I mentioned before, add the P3 RS-232 'thru' path, and the RS-232 cable between the P3 and the K3. Eliminate the P3 and the P3 to K3 cable by connecting the RS-232 cable directly to the K3. 73, Don W3FPR -- Ken, Since the K3 is doing its thing normally, try another USB to serial adapter, or another computer.

Re: [Elecraft] 50 Ohm Load - source?
I just built that RF load kit from OHR. Works as advertised. At 150 MHz, the impedance is 50 + j2, which is pretty good for metal oxide resistors. At HF, I can't measure any reactance but that's probably due to the SWR meter. The load is convection cooled (flow-through). Kit instructions are clearly written and easy to follow. 73, matt W6NIA On Sun, 29 Mar 2015 16:47:52 +, you wrote: I found this link: http://www.ohr.com/index.htm Robie - AJ4F On Sun, Mar 29, 2015 at 4:34 PM, Jim Miller jimmil...@stl-online.net wrote: I tried to Google it and made it to the OHR Website but could not find it.

[Elecraft] [KX1] 20m Power Out Question
Hi, all. I recently uncovered a bad solder on C41 that had been there from my initial build some years ago. Now I get 4.1w on 40m and 2.7w on 20m--both much higher than I've ever seen. I'd like to get more power out on 20m even if it takes away from 40m. L2 is wound pretty tight so there isn't much movement in spreading the windings. In searching the mail list for ideas, it does seem as if 20m should be closer to 40m. Should I rewind L2 loosely so it is easier to move around? Or leave it alone? And, yes, I've checked the number of turns on L1 and L2 as well as the capacitor values multiple times. These measurements are with the ATU out of the circuit.

[Elecraft] Elecraft CW Net Announcement
Good Morning, The arrival of spring in Oregon has brought back many birds and given me a few deer sightings. The hummingbirds, at least the first species, have returned and are busily eating bugs. More flowers are opening for them also. The weather has been unpredictable but no weatherman does very well around here. It is wet and cool in the winter and dry and less cool in the summer; that is accurate enough. Propagation has gradually improved over the week to where on Friday it was almost back to good. The solar wind has slowed but its effects have left the ionosphere in pretty good shape. While watching the stars come out last night I had the treat of a duet: a saw whet owl and a coyote were enjoying the dusk with a call and response routine. Here are the times and approximate frequencies of today's nets Please join us this afternoon and evening. 14050 kHz at 2200z Sunday (3 PM PDT Sunday) 7045 kHz at 0100z Monday (6 PM PDT Sunday) 73, Kevin.

Greetings all, Thank you all for the schematics for the KPA500 that was e-mailed to me off the list. After much gnashing of the teeth after looking at the schematics, I have decided to go the safe route. I will be sending the ailing amp back to Elecraft. Who would ever thought that you could get 17 pages of schematics into the small package that the KPA500 lives in and besides .. Elecraft will fix it within 15 days (maybe sooner) for $99.00 plus extra parts and shipping both ways. Could come to less than $200. N2QT - Not a word out of you!!! Ya hear?

Re: [Elecraft] KX3 ANT feature request

I have two antennas which need different tuner settings for each HF band. Whenever I change from one to the other I have to retune the ATU and vice versa when I go back to the other one. Would be so much quicker and easier to just select ANT 1 or 2 with that unused button on the KX3. __ 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] SSB net announcement
I always wondered about that too. 17 is hardly ever what you would call crowded. We're not limited for example, by celebrating radios that don't cover the WARC bands such as the Collins Collectors Assn. net later on 14.263 at 2000Z. Fun for the nostalgia aspect but pure h3ll when a big contest obliterates the band. (Sorry about the 'plug' for the CCA net.) 73, Charlie k3ICH - Original Message - From: Fred Jensen k6...@foothill.net To: elecraft@mailman.qth.net Sent: Saturday, March 28, 2015 11:53 PM Subject: Re: [Elecraft] SSB net announcement Phil, why don't you hold it on 17 meters this weekend? A number of the SOTA crowd that frequent the SSB freq's from summits went to 17 and 12 meters today. SFI is pretty high relative to what it has been, 17 might be a good analog for 20. 73, Fred K6DGW - Northern California Contest Club - CU in the 50th Running of the Cal QSO Party 3-4 Oct 2015 - www.cqp.org On 3/28/2015 8:47 PM, Phil Shepard wrote: The weekly Elecraft SSB net meets Sunday at 1800Z on 14.3035 MHz.

Re: [Elecraft] [KX1] 20m Power Out Question
Clark, Spreading or compressing the turns on the L1 and L2 toroids is the way to do it. So, do whatever you need to to accomplish that. Actually, you do not have to adjust all the turns, just move the end turns closer together or further apart. Yes, you should be able to achieve a bit more power on 20 meters, but remember that the KX1 LPF is a compromise - play with the toroids a bit to see what you can accomplish. Actually, you may be better off rewinding L2 on a new core (assuming you have one). I have found that some of those yellow cores vary in permeability, and if the one you have installed has a greater permeability than normal, the cutoff frequency of the LPF may be too low and shunt some of the 20 meter RF energy to ground. 73, Don W3FPR On 3/29/2015 1:55 PM, engineercm wrote: Hi, all. I recently uncovered a bad solder on C41 that had been there from my initial build some years ago. Now I get 4.1w on 40m and 2.7w on 20m--both much higher than I've ever seen. I'd like to get more power out on 20m even if it takes away from 40m. L2 is wound pretty tight so there isn't much movement in spreading the windings. In searching the mail list for ideas, it does seem as if 20m should be closer to 40m. Should I rewind L2 loosely so it is easier to move around? Or leave it alone? And, yes, I've checked the number of turns on L1 and L2 as well as the capacitor values multiple times. These measurements are with the ATU out of the circuit. __ 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
