Re: [Elecraft] KX3 Accuracy of clock

Phil, I, for one, use the KX3 clock readout every time I'm on a summit in subzero wind chills and my wristwatch is buried inside my heavy parka. Paper and pencil logging is hard enough in adverse field conditions, but having the clock right on the face of the KX3 helps a lot! The KX3 clock is

Re: [Elecraft] [ELECRAFT] KX3 Accuracy of Clock

Doing a little research I found a 32.768KHz surface mount crystal in the Newark Catalog that might be used to replace the crystal in the Battery/Clock module. It is an Epson MC306 and sells for $1.12 in the Newark catalog. The accuracy is 20PPM, which equates to about 10 minutes/year. Since

Re: [Elecraft] KX3 Accuracy of clock

I guess I have never understood why a clock on a radio was important. I guess unless you use it for automatic wake up or something. But, the one clock I wish I had was the clock for my old Hammarlund HQ-170A which needs a clock. I would never use it, it just needs to fill the space. I hate c

Re: [Elecraft] KX3 Accuracy of clock

I checked the time on my kx3 last night. After 5 weeks it hasn't changed or maybe a few seconds. Did I get the bad one out of the batch! Paul K7PM On Tuesday, December 3, 2013, Edward R Cole wrote: > Not sure how all this commentary on computer time applies to the topic title. My KX3 keeps perf

Re: [Elecraft] KX3 Accuracy of clock

I actually built one from an Arduino before. It's accurate within milliseconds (which is enough for JT65), but I'm sure it could be made better. (Source code at https://github.com/tmiw/arduino-ntpd if interested.) -Mooneer KG6AOV On Tue, Dec 3, 2013 at 4:31 PM, Ben Hall wrote: > For the very t

For the very time-obsessed, build and operate your own GPS-controlled NTP time server as described here: Yes, I admit, I have one of these serving network time here in my shack or "laboratory" as my 8 year old son calls it.

Re: [Elecraft] KX3 Accuracy of clock

Not sure how all this commentary on computer time applies to the topic title. My KX3 keeps perfect time since I did not buy the battery charger...no clock! My $12 wrist watch has about 1 second/year accuracy. The K3 clock drifts over a week or so, but is easily corrected using the Utility p

Re: [Elecraft] KX3 Accuracy of clock

If the capability exists, it would be nice if the PIC24F16KA102, "RCFGCAL: RTCC CALIBRATION AND CONFIGURATION REGISTER," "CAL<7:0>: RTC Drift Calibration bits" were configurable in a MUNU parameter. John KN5L On 12/03/2013 08:45 AM, pkhjr wrote: > The accuracy of the clock is very bad, but what h

Re: [Elecraft] KX3 Accuracy of clock

On Debian Linux and derivatives (Ubuntu and its variants, Mint and its variants, etc.) install the ntp package, sit back, and enjoy. The default configuration starts the daemon with a set of four NTP servers defined and no editing of a config file is necessary unless one has a local NTP server to

Re: [Elecraft] KX3 Accuracy of clock

On a Mac, open System Preferences, click on the Date & Time pane, and check the box for "Set date and time automatically". On Unix, read the appropriate RFCs and man pages. For extra credit, search the web for "ntp groper" and see what I was doing twenty years ago. wunder K6WRU On Dec 2, 2013,

Re: [Elecraft] KX3 Accuracy of clock

Even the native Win7 implementation is defective, updating only once every few days and not using the differences to make corrections between updates. Since I run HRD (running 24/7) and it has an NTP client in the DM780 program, I use that. But I will look at what the others have posted too.

That page says there is a built-in way to keep your clock synced, but it is hard to find. Why not just walk people through the documentation? In Windows Vista or later, you get a conforming implementation of NTP. Earlier Windows versions are broken, even though I was using NTP with no problems f

The KX3 Utility could estimate the clock adjustment, if it is the only thing that sets the clock. It knows the time it was last set and can measure the drift. wunder K6WRU On Dec 2, 2013, at 3:43 PM, Fred Jensen wrote: > Actually ... "atomic clocks" such as the UTC one hanging on the wall of

Actually ... "atomic clocks" such as the UTC one hanging on the wall of my shack [that I won at radio club raffle] don't "poll 10MHz." They listen for WWVB on 60KHz, which mine hears only at night here in CA. WWVB broadcasts a continuous IRIG-H time code with a somewhat obscure AM modulation s

Mine will drift a few minutes over a few weeks, but I do agree that 4200s in one week points at a problem somewhere. 73 Stephen G4SJP On 2 December 2013 03:39, Mike Morrow wrote: > > > After setting the clock accurately last weekend, I did not think > > about checking it this weekend but half

[Elecraft] [KX3} Accuracy of clock

Your deviation appears to be WAY off! Something else must have caused this that is different from the normal deviation. E.g., it has probably been a couple months since I reset my clock and it is about 30 seconds fast now. Still annoying when you need it to be precise. But then, Don has a point

Hi all, Does anyone know how accurate is the clock on KX3? The reason I ask is because I activated a local SOTA peak last weekend and did another peak this weekend. After setting the clock accurately last weekend, I did not think about checking it this weekend but half way through this week
