Re: [Elecraft] [OT] Ham Radio near high voltage power lines?
Jerry, I'm sure you can make something work. I used to have HV power lines about 150 yards from my house. It was only a problem during rain/snow/fog with conduction across the insulators. I had a cubical quad and could identify the offending pole and could likewise null out the noise. Oddly, I don't recall there being a problem on the 80m or 40m dipoles. You could always do a quick noise check with a mobile HF rig or a handheld AM shortwave receiver. __ 73, Jim - N4ST -Original Message- From: elecraft-boun...@mailman.qth.net On Behalf Of ae...@carolinaheli.com Sent: Tuesday, April 27, 2021 09:50 To: elecraft@mailman.qth.net Subject: [Elecraft] [OT] Ham Radio near high voltage power lines?

Re: [Elecraft] Gurus
FWIW, be careful with your measurement process. I got very depressed when I saw that my K3S had harmonics only 20db down on most bands when measured by Tiny SA and its telescoping antenna. It was not being overloaded and in fact I measured similar results when feeding a dummy load. Then I went outside the shack at a distance from the antennas and found that the harmonics were 40dB down or better.

Where is it (with respect to the shack)? 5el Cushcraft located 55 feet from the shack. 2. As others have observed, the first thing to check in any system when something like this happens is to suspect EVERYTHING in the antenna system, ESPECIALLY ever piece of coax and every connection. That means getting serious to check that every connector is wrench tight, and to "rattle" all cables and connectors while watching for any changes. By passed Daiwa antenna switch. Swapped coax jumper cables. 3. What WAS the SWR on CW? What was it on FT8? 1.1-1.2 SWR on CW. Meter pegged +10 on FT8 4. What happens if you click on TUNE in the software you're using for FT8? That is how I have done the FT8 testing. 5. What power did you use for each mode? Have used 50W & 100W on CW. 8W, 10W & 50W on FT8 The FT8 SWR is fine at 8 watts, before K3S PA is engaged. No good at 10W when the PA kicks in. 6. Are any of your coax connectors, including adapters, junk? If they don't say Amphenol 83-1SP, or have a MIL spec number stamped on them, there a VERY good chance that they are JUNK. When I got back on the air in 2003, I filled my parts stash with all sorts of no-name adapters from ham vendors. Over the next 6-8 years, they caused me all sorts of grief. Flimsy construction, spring wire in elbow adapters, out of physical tolerance center conductors that don't mate well to form a solid contact. I had Tee adapters fall apart. I may have some "junk" connectors. DX Engineering crimp/solder PL-259s. Have swapped jumpers. Bypassed antenna switch. No observable difference.

Hold TUNE to do automatic power calibration on 6 meters at the 50 W level. After a few seconds, tap XMIT to terminate the TUNE operation. NOTE: If you have difficulty reaching full power on 6 meters after making this change, it could be because your PA module is actually a KPA3, not a KPA3A. In this case, re-do the above procedure, changing the TXGN HP menu setting back to the original (i.e., without "ATN6" showing).

Re: [Elecraft] What is a reasonable turnover time to hear from Elecraft support:
Depends on the issue. In my case it was just some replacement K3S modules. Here is my time line for a recent issue. 4/12 - K3S PA failure reported to Elecraft 4/14 - Email from Elecraft with testing procedures. 4/20 - RMA received and LPA/PA returned to Elecraft 6/13 - Refurbished new style LPA/PA received 6/14 - Configuration assistance from Elecraft - Back on the air. So for me it was about 1 month from reporting initial problem to received "new" parts and that included a 2-week vacation by the guy handling the RMA accounting. FWIW, I never called Elecraft although they did call me to discuss testing procedures/results. 73, Jim - N4ST -Original Message- From: elecraft-boun...@mailman.qth.net On Behalf Of CUTTER DAVID via Elecraft Sent: Wednesday, June 15, 2022 00:03 To: Stephen Dubin ; Stephen Dubin via Elecraft Subject: [SPAM] Re: [Elecraft] What is a reasonable turnover time to hear from Elecraft support: __ 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

For some reason, your email and a couple others recently are showing up as [SPAM] ??? __ 73, Jim - N4ST -Original Message- From: elecraft-boun...@mailman.qth.net On Behalf Of CUTTER DAVID via Elecraft Sent: Wednesday, June 15, 2022 05:09 To: Elecraft@mailman.qth.net Subject: [SPAM] [Elecraft] What is a reasonable turnover time to hear from Elecraft support: I answered this today and the response from the reflector came in blank.

Re: [Elecraft] Field Day and FT-8
New QTH and only a 33-foot vertical for an antenna so far, so wasn't going to play Field Day. Finally broke down and made 50 FT8 contacts in a little over two hours Sunday afternoon. Didn't nano-analyze the signals, but only saw a couple of obvious problem signals, mostly 3X audio harmonics . Some shack room noise being transmitted from a hot mike. Did notice that a lot of folks insisted on calling on freq instead of operating split. _ 73, Jim - N4ST -Original Message- From: elecraft-boun...@mailman.qth.net On Behalf Of Bob McGraw Sent: Monday, June 27, 2022 12:54 To: elecraft@mailman.qth.net Subject: [Elecraft] Field Day and FT-8 AMEN!

Re: [Elecraft] K3 INTERFACE WITH LDG Z100A
I have tried to find a way to interface a K3S with an LDG-200. It needs a digital to analog conversion interface since the LDG uses discrete voltage levels as inputs for the proper band. I don't know if the Z100A uses the same analog signaling. In the mean time, I wrote a macro to drop my K3S to 20Watts, do a TUNE, wait 2 seconds and then cancel the TUNE and bump the power back up to 70W for digital work. A one-click mouse solution for using the LDG memory auto-tune. _ 73, Jim - N4ST -Original Message- From: elecraft-boun...@mailman.qth.net On Behalf Of Bob McGraw Sent: Sunday, September 4, 2022 09:35 To: elecraft@mailman.qth.net Subject: [Elecraft] K3 INTERFACE WITH LDG Z100A I purchased a Z100A with the idea of interfacing it to a specific brand/model of radio. I investigated the Z100A requirements to initiate the control of the tuner via the transceiver. From my earlier work, I don't see there is a command from the K3 that will support the requirements of the Z100A. However, there are many ICOM radios that do have the provision. Thus the command comes from the radio. From the LDG manual: "The LDG Z-100A includes the IC-104 DC power cable, as well as a three foot IC-100 Icom interface cable. However, interface cables for a plethora of other radios are available as an optional purchase, definitively making the Z-100A the last tuner you'll ever need to purchase. Press "Tune" on Tuner - Keys Automatically * IC-105 Alinco interface cable - uses EDX-2 jack, DX-70 and DX-77 * IC-108 Yaesu interface cable - uses TUN/LIN and KEY jacks, FT-891, 991/A, 857, 897, 100 * IC-109 Yaesu interface cable - uses TUN/LIN jack, FT-DX10, 1200, FT-950, 450 (NOTE: Do not select external tuner in settings) * IC-115 Yaesu interface cable - uses LINEAR jack, FT-DX101D, 3000 * IC-106 Kenwood interface cable - uses AT-300 jack * IC-105 Alinco interface cable - SR8T, SR9T" * Compatible with any Icom radio that is AH-4 or AH-3 compatible. (6M tuning from Tuner button for radios that are only AH-3 compatible) * Partial radio list: IC-706, 703, 718, 7000, 7100, 7200, 7300, 7410, 746, 756, 7600, 7610 (and all variants). I find nothing to indicate the LDG100Z will interface with the K3. In reviewing the signals on the ACC connector on the K3, I do not find one dedicated to the TUNE function.

Does the tuner have to get connected to the K3 ACC jack?? Or does someone have a wiring diagram so I can marry the correct connections between the 2 units? 73?s, Greg N9GB O __ 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 hamsh...@n4st.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
