Re: [Elecraft] Buggy software OT
This needs to stop here, but since Kent is saying that I don't understand, I'm going to reply. Once. We were talking about how a hypothetical airliner control system would have two different programs, written by different groups, running parallel, with either program capable of flying the plane. Part of the flight system could crash that the pilots and passengers would not notice. Airplanes in flight have to have controls that work in milliseconds without a glitch. With MRO, we have Lockheed software doing navigation, but not flying the spacecraft. JPL software flew the spacecraft, but did not navigate. If JPL did their own redundant navigation, the error would have been caught. It's not like they didn't have time, there was a week between the calculation and the burn. The facts in the Wikipedia article are correct, it just doesn't describe a system that has any redundancy. I will not comment further on this topic on list. We're way over the limit on off-topic posts. 73 -- Lynn On 1/17/2015 12:30 PM, KENT TRIMBLE wrote: Facts can also be factual.

Re: [Elecraft] Buggy software OT
The Airbus software won't let the pilot do anything that might break the airplane. The Boeing software doesn't have the same limits. I believe there are accidents attributed to both. For critical systems, there are often two different programs, written by different groups of programmers, either of which can fly the airplane. The assumption is that they'll have different bugs. On 1/17/2015 12:40 AM, Fred Townsend wrote: I think there is a big difference in flight software. In Boeing airplanes the pilot is assisted by software.

Facts can also be factual. Kent K9ZTV /On November 10, 1999, the Mars Climate Orbiter Mishap Investigation Board released a Phase I report, detailing the suspected issues encountered with the loss of the spacecraft. Previously, on September 8, 1999, Trajectory Correction Maneuver-4 was computed and then executed on September 15, 1999. It was intended to place the spacecraft at an optimal position for an orbital insertion maneuver that would bring the spacecraft around Mars at an altitude of 226 kilometers on September 23, 1999. However, during the week between TCM-4 and the orbital insertion maneuver, the navigation team indicated the altitude may be much lower than intended at 150 to 170 kilometers. Twenty-four hours prior to orbital insertion, calculations placed the orbiter at an altitude of 110 kilometers; 80 kilometers is the minimum altitude that Mars Climate Orbiter was thought to be capable of surviving during this maneuver. Post-failure calculations showed that the spacecraft was on a trajectory that would have taken the orbiter within 57 kilometers of the surface, where the spacecraft likely disintegrated because of atmospheric stresses. / /_The primary cause of this discrepancy was that one piece of ground software supplied by _Lockheed Martin http://en.wikipedia.org/wiki/Lockheed_Martin_produced results in a _United States customary unit http://en.wikipedia.org/wiki/United_States_customary_units_(American), contrary to its Software Interface Specification (SIS), while a second system, supplied by _NASA http://en.wikipedia.org/wiki/NASA_, that used those results expected them to be in metric units, in accord with the SIS. _Software that calculated the total impulse produced by thruster firings calculated results in pound-seconds.

[Elecraft] P3 SVGA WaterFall Marker Issue
Just loaded the latest P3 Beta to get WaterFall Markers. Thanks for the feature. But... I noticed a curious behavior. Using the button on my P3 which is programmed for WfallMkrs I noticed it's not controlling the SVGA marker as it does the P3 display marker. If I start with VFO A Marker off and Waterfall Marker off. Turn on VFO A marker then tap the button for the Waterfall Marker. P3 behaves normally. The SVGA does not display the Waterfall Marker. If I tap the MKR A button on the P3 to turn it off, then tap it again to turn the VFO marker back on, both the P3 and SVGA display the Waterfall Marker. If I then tap the button I have programmed for WfallMkrs the P3 turns off as expected but the SVGA continues showing the marker. Two taps of the MKR A button to turn off and then back on gets the displays in sync again.

Re: [Elecraft] K3 bugs
Dave, Maybe I overlooked it in your initial post, but I did not realize you had no microphone connected. Given those additional facts, I also believe there is some kind of bug causing it. It is good that you noticed it.

I suspect that with VOX on, the TX momentarily would more likely be caused by some sort of noise in the shack. If you have the VOX set sensitive enough, then even tapping on the operating desk or moving the microphone (or even chair 'squeaks) can cause it to go into transmit easily. If the ANTIVOX setting is too low, that may trip the K3 into transmit with sound from the speaker (or leakage from the headphones. You may want to check your MENU: VOX GN and MENU:ANTIVOX settings to be certain they are not the problem. Those settings are dependent on the sensitivity of the microphone, proximity of the mic to the speakers, and other factors dependent on your shack and the ambient noise conditions in the shack, so settings that are good for one situation will likely not work well in your situation.

Two more observations. If I turn the Waterfall Marker on and have it displaying on both P3 and SVGA then tap the assigned button to turn the Waterfall Mark off, it stops displaying on the P3 but on the SVGA where the marker is displaying the marker stays with the VFO frequency. If I turn the P3 knob to move the VFO A marker the waterfall line stays centered on the VFO Frequency and with a knob tap to QSY the marker line remains with the VFO A frequency. The MKR A frequency display in the upper left corner of the SVGA display disappears after a knob tap to QSY. The marker frequency continues to be displayed on the P3 display. Don't recall if it was that way before the upgrade. Tighe NK4I On 1/17/15 6:09 PM, Tighe Kuykendall wrote: Just loaded the latest P3 Beta to get WaterFall Markers. Thanks for the feature. But...

[Elecraft] Fixed: K1 AF sidetone loudness proble
Hello, i got it fixed. The fix was described earlier in this thread - replacement of Q10 (2N7000 Mosfet) and Q11 (J309 JFET) on the RF Board did it for me. By the way: The J309 seems to be discontinued..

Re: [Elecraft] Need size of Allen wrench for small knobs on K1
David, I don't believe you will find a proper fitting wrench in a set of metric Allen wrenches. 1mm is too small and 1.5mm is too big :-) . Those with only metric wrenches should guard the ones that come with the K1 (K2, KX1, K3, KX3 etc.) carefully. 73, Don W3FPR On 1/17/2015 4:27 AM, David G4DMP wrote: In a recent message, George Averill aver...@mchsi.com writes Can someone please tell me the size of the Allen wrench that is used to attach the small knobs on a K1?

[Elecraft] [KX3] FYI - Eneloop XX Battery Manufacturer Change
I was about to purchase some additional Eneloop XX 2500 mAh batteries this morning from Amazon.com http://amazon.com/. I went back to previous purchases and noticed that they were no longer available. Copying-and-pasting in the search window found them again, but they’re now manufactured by Panasonic (previously, they were Sanyo). I cannot imagine there is any difference in the batteries. I’ve never had anything buy high praises for the Eneloop XX batteries. I put them in *everything* that’s why I need more. :) Eight are in the KX3 at all times and I have about eight more scattered throughout the house in remote controls, BT keyboards, etc. If you don’t hear anything back from me, I guess they work just fine. :) 73, Joel - W4JBB __ 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] Getting the bugs fixed
When it comes to bugs (software and/or hardware) I do not feel there is another ham radio manufacturer as responsive as Elecraft. I personally experienced this when I first got my KAT500/KPA500 units. Long story and loads of emails - within a couple of weeks I was sent a new software to install. Elecraft had listened - without making excuses or attempting to redirect the problem. My problem vanished and I have been enjoying my K-Line ever since. A flawless system that meets all of my needs perfectly (other's mileage may vary). I can tell you from experience, not rumors or tall tales, that other current manufacturers I have dealt with would not have been anywhere as responsive. Kudos to Elecraft!

[Elecraft] K3 tuning power question
I want to verify my understanding. In the interest of protecting the output transistor(s) against a mishap in one's antenna system, would it be better to tune at 10 watts (finals off) or at 15 watts (finals on)? Or is the driver so well protected that it doesn't matter?

Re: [Elecraft] [KX3] FYI - Eneloop XX Battery Manufacturer Change
The explanation is that Sanyo and Panasonic merged some time ago, and they finally retired the Sanyo brand. But those are the same batteries.

Re: [Elecraft] K3 tuning power question
Hi Dick, The K3 uses either 5 or 10 watts to tune the internal KAT3 tuner. Mine uses 5 watts and I'm not sure under what conditions it would use 10 watts. You can see the tuning power used briefly displayed in the VFO B area when you tap the ATU TUNE button. By the way, the TUN PWR menu doesn't affect the power used when tuning the tuner. It sets the power output when you hold the TUNE button.

Re: [Elecraft] K3 tuning power question
Dick, It is easier on the K3 to tune at 15 or 20 watts. Reason -- at 10 watts, only the low power PA is active and it will be operating near the upper end of its range. Increasing the power activates the 100 watt amp and at 15 or 20 watts, everything is loafing along at much less than its full output. 73, Don W3FPR On 1/17/2015 10:00 AM, Richard Fjeld wrote: I want to verify my understanding.
