Re: [Elecraft] OT: Changes at WWV, WWVB
There's some wrong information being propagated here. Somehow the failure of frequency comparators and/or frequency standards that were based on doing a PLL with the CARRIER of the WWVB signal is being extrapolated to the failure of all Radio Controlled Clocks which do not track the carrier but instead read the time code that is imposed on that carrier. This is completely wrong. The new Phase Modulation signal is imposed on top of the legacy PWM signal that has been broadcast pretty much since the beginning. Radio Controlled Clocks that just read the PWM encoding should not be affected by the phase changes of the PM signal, and will still work as before. The reason that some clocks may only get a lock at night is purely an issue of propagation, and will almost certainly be true for clocks located in the eastern part of the US. In fact, that is the primary reason for adding the PM signal, since it can be decoded at lower signal strengths than the PWM signal can be decoded. However, devices like the HP-117 and Spectracom 8170 performed a PLL on the carrier of the signal, since the carrier frequency itself is very accurate. These are broken by the addition of the PM signal, since it is flipping the phase of the signal by 180 degrees periodically. None of the cheap consumer Atomic Clocks do this (phase lock the carrier). People have developed external circuits that reclock the WWVB signal and allow these type of devices to continue to work. Also, WWVB did shut off the PM part of the signal for a few hours every night during a transition period that ended in May 2013. That is no longer happening, but again this only affects phase locking receivers. Specifically LaCrosse states clearly on their website that their clocks are not affected by the addition of the PM signal. Finally, I don't think there any commercially available clocks, at least at the consumer level, that support the new PM signal at this time. The decoder is patented, and I believe chips that support it are either still in development or only recently released. I'll try to do some more research regarding this.

Re: [Elecraft] OT: Changes at WWV, WWVB
There seems to be a lot of misinformation and misunderstanding about how consumer WWVB consumer clocks and watches sync and what the changes to the format at WWVB mean to them. The following which give the details from the horse's mouth http://www.nist.gov/pml/div688/wwvb-030513.cfm http://www.nist.gov/pml/div688/grp40/wwvb.cfm Consumer clocks and watches that sync to WWVB old and new generally are not affected by the changes to the modulation scheme. The changes do affect frequency standard products that phase locked to the carrier, and some specific clocks that used synchronous AM detection, not your Radio Shack atomic desk clock. The reason WWVB clocks check around midnight is because the reception is generally much better at night and with fewer interference sources switched on there is a better signal to noise available at the receiver. I would venture to say that most clocks that have stopped working as well as they did in the past would be because of an increase in interference levels due to our modern digital lifestyles and poor enforcement of EMC standards, not the change of the WWVB modulation to add PSK which is backwards compatible to the old scheme. 73 David Anderson GM4JJJ On 29 Nov 2014, at 02:16, david Moes dm...@nexicom.net wrote: I recieved a new la Crosse clock about two months ago In the instructions it stated that it would only sync a a specific time at night.And now I know why.

Re: [Elecraft] K2 Lo p on 10 12m when its cold outside.
Ed, Since those easy steps did not reveal the problem, you will have to resort to some Transmit Signal Tracing to find the problem. Use the stage-by-stage points shown in the manual Appendix A page 14 starting at the middle of the left column. BUT you will have to deviate from the instruction to set the K2 on the 40 meter band - use a failing band instead. If the measured RF voltage is greater than the expected value, that is OK. What you are looking for is the 1st stage in the sequence where the RF voltage is significantly *less* than the expected value. That is the output of the failing stage. 73, Don W3FPR On 11/28/2014 10:50 PM, EMD wrote: Hello Don, Thanks for your reply.

[Elecraft] KAT500 question
Our KAT500 (used with K3 and KPA500) seems to have forgotten its correct memories for the 20 m band or maybe developed new erroneous memories. It gives me 14 to 1 on autotune. If I set it on manual and do a tune it reads 1.2 to 1. So here is the question: if I do manual tunes every so many MHz across the band will those go into memory, or is the memory based only on autotunes? Also, any idea how this happened? THANKS!

Re: [Elecraft] [ELECRAFT] K3: Help! No output on 80m CW
The average power of voice is far below that of CW. If there is a corroded connection that is heating up and failing, then cooling and reconnecting, it could be happening with CW and not SSB. Try reducing the output of the KPA500 to 100 watts on CW and see if the trouble goes away. We one time had a failure something like this at NY4A. The trouble was traced to a male/female UHF elbow coax adapter, one of the cheeep, cheeep kind that makes the center connection around the bend in the elbow with a spring in the center. This is easier to manufacture than the good kind, which is why they are cheeep. Over time these springs heat up, lose their tension, corrode at the connection points, and display weird symptoms like you describe. Worth checking out. The only reliably non-spring elbows are Amphenol's, where the male center pin screws into the conductor from the female side. Once you know what to look for, you can tell in an instant. Throw all the spring based elbow coax adapters into the trash. They cannot be rehabilitated. If you get any from a supplier, send them back and demand a refund. I walked around a hamfest and easily found 25 of the Amphenol types to take home. You can also get the same kind of symptoms from a PL259 where the braid was not soldered, or has undergone exceptional amounts of flexing, or has lived for a long time at a current max at a high current place. These issues are exacerbated by cheeep coax with lesser amounts of conductor in the shield. Good luck 73, Guy K2AV On Fri, Nov 28, 2014 at 10:13 PM, tom...@videotron.ca wrote: Ok more detail.

Re: [Elecraft] KAT500 question
All full search tunes, whether started by manually pressing the TUNE button or an SWR-based autotune, store the tuning solution in memory. I'd suggest you erase the tuner settings for 20 meters on the affected antenna connector KAT500 Utility configuration tab) and train the tuner by pressing TUNE and provide a 20 watt tune signal on a few frequencies across the band. You don't want remnants of the erroneous settings in those memories, or you'll keep finding them. Then leave the ATU in mode MAN so that it selects from previously found tuning solutions as you QSY across the band. As for how you got there - I can speculate, but I don't know anything about your path from ATU to antennas. It probably matched a different impedance at some point in the past. I might get that result here by having an external antenna switch in the wrong position and use the KAT500 to match my 15 meter beam on 20 meters, and then change my antenna switch. You probably don't want the ATU in mode AUTO very often. After antenna configuration changes, erase the tuner memories on the affected bands, and tune at a few spots on the band. Then let the ATU choose from those settings by frequency, which it will do in mode MAN. 73 de Dick, K6KR On Nov 29, 2014, at 06:17, jsdroys...@nc.rr.com jsdroys...@nc.rr.com wrote: Our KAT500 (used with K3 and KPA500) seems to have forgotten its correct memories for the 20 m band or maybe developed new erroneous memories.

Re: [Elecraft] VOX SET Command?
Joel, Perfect! I found I must put the command at the end of the string on my Digital PF and it must be first in the voice one. That latter because if it is at the end, the KX3 goes into a state where the VOX trips and clicks repeatedly until you kill power to the rig. Easy fix. I was looking on Page 23 of that same revision of the manual and did not look further because of what it stated there about the command.

Re: [Elecraft] KAT500 question
Hi Yes erased the 80m and then did a bunch of tunes across the band, all OK.

You sure have that right re interference due to modern digital lifestyle, David.

Re: [Elecraft] [OT] Pignology
Hi all, I quite agree with you. Pignology products are really good. I have Piglet and Pigknob . They offer a high standard of quality and provide you an easy and comfortable operating . They are easy to use and configurate. They are a good option when you are in the field or coast, with activations, and you do not want your radio equipment to get dust or harm! I carry them with me most of time. I can say they have become in an essential element for my activations. On the other hand, they are just small boxes that you can carry in any pocket of your radio bag. They occupy quite little space. At home they are also quite useful because you can operate from any place, on sofa , in chair... I do recommend these products.

Re: [Elecraft] OT: Changes at WWV, WWVB
Another thing to watch out for on these 'atomic clocks' appears to be nearby lightning strikes. I have 3 of the clocks here. Two are not affected but the other one, after any fairly nearby thunderstorm, requires that I remove the battery, let it completely discharge all energy held within (this takes a few minutes as they are very low power drain and apparently have decent sized caps inside) and restart it. It will then lock up and stay that way until the next thunderstorm rolls through. But once a storm rolls through, it will unlock and refuse to re-lock not matter how many times I press the 'resync' button. Something appears to get hosed up in its OS and it declines every attempt to resync it. I can tell when it has lost sync by checking the little 'sync' icon. And, of course, the time is off . . . 73 de dave ab9ca/4 On 11/29/14 11:30 AM, Joe Subich, W4TV wrote: Unfortunately the consumer clocks seem to attempt to sync between 0200 and 0400 *local* (display) time regardless of the time zone.

Re: [Elecraft] KAT500 question
It depends on the antenna impedance (the unmatched or SWR measured with teh ATU in bypass). If the unmatched antenna SWR exceeds 10:1, at 600 watts, the ATU might be faulting to protect itself. What does your KAT500 fault table say? The ATU is rated to match antennas with 10:1 SWR at 600 watts, 3:1 SWR at 1000 watts. If the unmatched SWR exceeds 10:1, the ATU might disconnect the amp at a lower power to protect itself from destructive current through its inductors.

I might get that result here by having an external antenna switch in the wrong position and use the KAT500 to match my 15 meter beam on 20 meters, and then change my antenna switch. You probably don't want the ATU in mode AUTO very often. After antenna configuration changes, erase the tuner memories on the affected bands, and tune at a few spots on the band. Then let the ATU choose from those settings by frequency, which it will do in mode MAN. 73 de Dick, K6KR On Nov 29, 2014, at 06:17, jsdroys...@nc.rr.com jsdroys...@nc.rr.com wrote: Our KAT500 (used with K3 and KPA500) seems to have forgotten its correct memories for the 20 m band or maybe developed new erroneous memories. It gives me 14 to 1 on autotune. If I set it on manual and do a tune it reads 1.2 to 1. So here is the question: if I do manual tunes every so many MHz across the band will those go into memory, or is the memory based only on autotunes? Also, any idea how this happened? THANKS!

[Elecraft] K-Line Full break-in
I set my K3 to QSK but I don't know how to make it FULL BREAK-IN.

[Elecraft] KX3 - First 2 meter CW contact
Just finished a 15 mile CW QSO on 144 MHz using the KX3's internal 2 meter transverter. Antenna on my end was a Ringo Ranger (vertically polarized) only 12 feet off the ground and the antenna on his end was also a Ringo Ranger but his was on a real short (6 foot) ground mounted mast. There is quite a bit of hilly terrain between us and signals were only 539 both ways but with the low noise on the band copy was real easy. We tried SSB but I don't have the latest Field Test firmware in my KX3 and the transverter is putting out maybe a watt on SSB. It does the full 3.0 watts on CW. Also as previously reported, CW using the internal keyer is kind of messed up. It misses character elements and gets choppy at times. I didn't have time to try external keying with my bug but that will come in another test tomorrow.

[Elecraft] VFO tracking
I am using a friends K3 at NP2X this weekend, and quickly noticed that VFO B tracks VFO A when in Split mode. I have never seen this happen on my K3, and am unable to find out to stop B from tracking A. Yes, I have RTFM, but am still in the dark? Suggestion please. Go easy on me, I'm not on the island rum! 73, George, K5KG/KP2 Sent from my iPad __ 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] VFO tracking
There's a CONFIG menu item that locks VFO B to VFO A. Unfortunately, I don't remember the exact name of the setting and I'm 250 miles from my K3. Hope this helps at least a little bit. 73 de, Ian, KM4IK On Nov 29, 2014 5:41 PM, K5KG Email via Elecraft elecraft@mailman.qth.net wrote: I am using a friends K3 at NP2X this weekend, and quickly noticed that VFO B tracks VFO A when in Split mode.

Re: [Elecraft] VFO tracking
George, That happens when the VFOs are locked.

If your in split, and the VFOs track, you have to hold the sub button to unlink the VFOs. George, That happens when the VFOs are locked.

Re: [Elecraft] VFO tracking
Sorry for my slip. Yes, Merv is correct - the VFOs are linked not locked - my only excuse is that they both start with L. 73, Don W3FPR On 11/29/2014 6:25 PM, Merv Schweigert wrote: If your in split, and the VFOs track, you have to hold the sub button to unlink the VFOs.
