Re: [Elecraft] K1 E42 error msg
Rick, Yes, E42 says that the MCU is not detecting a signal from the VFO. You can try re-flowing the soldering in the VFO area. If that does not restore proper operation, then more in-depth troubleshooting is required. Try DC voltage checks at Q8 for starters - the drain should be at 6 volts, and the source should be less than 1 volt. The gate should be a small negative voltage if Q8 is oscillating. If those values are OK, then it may be that the buffer (Q8) is not sending the VFO frequency to the MCU. 73, Don W3FPR On 6/10/2016 9:20 PM, Rick Whitworth via Elecraft wrote: I have an older K1 that has been working fine but now i get an E42 error msg which the manual says is a vfo issue.

Re: [Elecraft] This will effect pilots and Hams throughout the Western US
That's going to be difficult to answer without knowing just what effect these "events" will have on the signals received by the GPSDO's control receiver. If the GPS signals are "spoofed" the GPSDO could very well be driven off frequency, causing the K3EXREF to cause the radio's frequency to be off by quite a bit, actual amount and direction unknown. If the signal simply is blocked, the effect will probably be very minimal and will vary by the frequency and stability of the GPSDO's unlocked crystal oscillator. Without knowing exactly what they are doing, and exactly how that will affect the actual reception of the GPS (or GLONASS) signals, it will be impossible to predict exactly what will happen and that's why it should be of concern.

If it is a concern to those with the K3EXREF, what happens to their frequency stability? Are they now off frequency? What is plan B if your K3EXREF reference fails? Does this even affect those?

Re: [Elecraft] This will effect pilots and Hams throughout the Western US
Whatever they're testing, it isn't commercial aircraft. The article seems to suggest that it's a jammer, and that makes some sense. They may be testing a system to detect intentionally distorted GPS. While it may affect a whole lot of stuff (like the cell phone network), an FAA Notice to Airmen would only cover things the FAA cares about. 73 -- Lynn On 6/10/2016 2:56 PM, Kevin - K4VD wrote: Testing and practice all make sense but what isn't making sense about this is that we're disrupting GPS.

Re: [Elecraft] This will effect pilots and Hams throughout the Western US
How times have changed. Back in 1997, when I was working as a contractor for my old company, Hughes Missile Systems (now Raytheon), I worked on implementing some jamming tests on the Tomahawk missile GPS. FWIW, we put the missile section on a wooden pedestal covered in RF absorber on top of the rotating plate (also covered in absorber cones) under "The Arc" as seen here: http://www.kgun9.com/news/local-news/test-facility-at-ft-huachuca-assures-working-communications-equipment-for-soldiers Just for giggles, I climbed (took the stairs) "The Red Tower", the top of which would contain a good sized ham shack. The tower is completely wooden and held together by fiberglass bolts. The "dish" that is behind the guy being interviewed is actually a shaped reflector that in combination with a horn located below ground level forms a folded "compact" range, for those who understand such things. The leaning airfoil shaped tower holds the test subject at the plane-wave focal point of the reflector. An M1 Abrams tank can be supported and rotated on top of this tower. We had to do our testing in the wee hours of the morning, with secure communications links to range people who could tell us to shut down at a moments notice and our jammers were on a, few minutes on-lots of minutes off schedule.

Re: [Elecraft] This will effect pilots and Hams throughout the Western US
Testing and practice all make sense but what isn't making sense about this is that we're disrupting GPS. Lots of stuff other than military rely on GPS and - just my humble opinion - It seems a little freaky that they are testing commercial aircraft. Wouldn't as valid a test simply be to turn off the GPS receiver? I mean testing for a power outage at a commercial data center doesn't require turning off power to the city. It all kind of seems strange to me.

[Elecraft] [KX3] Adding TX/RX "Relay" to KX3 Operation
All, Oh the things that come up for Field Day with just weeks left to prepare. Say someone commits to bringing a "mighty-fine" RX only electrically steerable antenna of some sort to field day 2016. Not wanting to be forever mechanically switching between TX and RX antennas... How would you approach adding an automatic TX/RX swtiching capability to a KX3 operating QRP? Would you consider some sort of "diode" switch or stick with good ole mechanical relays? I have my thoughts, but thank you all in advance for yours.

Re: [Elecraft] [OT] Street Lamps and RFI
I don't think so Jim, but don't put any money on what I think. Most of 47CFR that deals with such standards seems to classify emitters based more on their usage rather than location. I suspect that "street lighting," even if in a residential area would not have to meet Class B standards. Not that that would matter anyway, it appears that no one is enforcing any of this. 73, Fred K6DGW - Northern California Contest Club - CU in the Cal QSO Party 1-2 Oct 2016 - www.cqp.org On 6/9/2016 9:57 PM, Jim Brown wrote: On Thu,6/9/2016 5:46 PM, Phil Kane wrote: Although we wish that it would be so, it is very doubtful if there are any street lamps that are certified to meet FCC Part 15 standards as Class B devices.
