Try at 19200 (or other speeds).  If I recall correctly, you can 'talk' to the P3 at whatever speed you wish, but it talks to the K3 at 19200 only.

On the other hand if you're not serial connecting the P3 to the K3, the baud rate is in the K3 menu.

When I disconnect the RJ45 from the radio, communication is complete and I can install updated firmware and I can use N1MM+ logger for the upcoming contest. I do not have the E980297 cable I can use for the second option. I would like to retain the complete functions of the P3. The RS232/P3 and USB ports can not be active at the same time?

New release of Win4K3Suite

Tom Blahovici
 

Hello,
There is a new version of Win4K3Suite available.  This release improves the SDRPlay interface, includes a Startup macro and has overall improvements.
 
Win4K3Suite is a full featured control program for the K3/S, KX3 and KX2.  It has a built in Panadapter that works with LPPAN and a sound card, as well as the SDRPlay RSP's. It supports the KAT500, KPA500/1500 and the KXPA100 on most of the above radios.  
A unique feature is that is has 6 built in Virtual Radios, each of which works just like an Elecraft radio.  This allows sharing of a single COM port with up to 6 applications.  It also has a built in HRDLogbook server and the EiBi Shortwave database.
You see more information here: https://www.youtube.com/results?search_query=win4k3suite
and download a fully functional 30 day trial at va2fsq.com

Re: Loses Time

And a day later I'm +1 second on the clock immediately after I turned the radio on.   Things may have improved a lot for me with this adjustment over a long time period like a day.  Time will tell I guess.  Over short time periods I wouldn't trust the clock very far.

So adjust if you want.  Don't rely on the clock unless you really just can't afford the extra weight of a wrist watch on your backpack trip with the radio.

I'm using a 10x probe. 100x might be better but I don't know the circuit.  I don't like loading down oscillators which could shift the frequency I'm trying to adjust.  This is a cheap but very good $120 or so frequency counter from China and is being fed around the back with a 10MHz external reference (Trimble Thunderbolt GPSDO).  This version is good out to like 6GHz.  Not a sales pitch, but my HP units can't beat it for portability.

I needed to use a pretty skinny probe to reach back to the PCB.  There's a hole for the tip of the probe to slip into if you can reach it (I couldn't with the original probe I tried).    Definitely ground your probe shield somewhere.  I'm clipped to a 1/4" jack for paddles.  The little hole right next to it has the trimmer pot/cap (can't quite tell from out here).  I used a ceramic blade adjustment tool, but plastic would likely be better only due to the fact that it's a tight fit and the ceramic isn't exactly bendy.  Plastic probably would get around the scope probe a little easier -at least with mine.

My gut feeling is to recommend some minimum warmup time like 15-20 minutes before doing this adjustment.  I turned it on and spent maybe 5 minutes looking around for the counter (lost the darn thing on the workbench -it's small!)  I've already drifted about 0.12 Hz, but this kind of thing isn't exactly a precision oscillator with double ovens and all that.   That said, I'm optimistic that my clock won't be terrible now.

Re: Loses Time

It just speaks to the garbage clock that Elecraft is using.  I was hopeful the cal would help but it seems to be where it was before I started.   The cheapest junk watches from Walmart keep better time than a Rolex.  Elecraft must've gone way out of their way on this clock.   Or something else is going on that I don't see.  Either way, the internal clock is useless.

The “Elecraft K3: Front Panel - Power and RTC” schematic sez 32kHz, and that there’s a trimmer!

Keith,

I suspect you mean 32.768 kHz, not MHz, which is a standard real time clock frequency.

Your K3S tunes above 30 MHz?  Mine doesn't.

If the frequency given isn't a typo, the K3 won't tune that frequency or any of its harmonics.

I would tune to a high harmonic and so use the accuracy of the K3 reference.

 

Many clock and watch crystals are optimised for a body-worn temperature, or about 25Celcius.

The K3"S" has a tweaker under the main VFO knob. You will need a very accurate freq counter. 32.768Mhz. The K3 clock is not very accurate and no adjuster.
I have replaced the CR2032 during repairs per owners request, but the old battery always has good voltage.
IE I have NEVER seen a dead or leaky one. If you don't use the clock, you can take the battery out. It only keeps the clock time.
