K4 Field Day report

Administrator

George (KJ6VU), John (KJ6K) and I operated a basic K4 for several hours as the 20 meter CW station at the Bay-Net Field Day site east of San Jose. This was the K4's first outdoor shake-down. The stakes were high, since the K4 has to pick up where the K3S/P3 leave off, fulfilling a dual role as both a high-end desktop and field/portable station.

Observations:

- the light weight (~10 pounds) made it easy to transport and set up

- there was virtually no mutual interference between the K4 and a very active 40 meter SSB station using an antenna about 40' away

- thanks to the low noise at this location we were able to hear many weak signals clustered together, and found signal clarity to be excellent

- the LCD was clearly visible, without color washout, despite a full assault by bright sunlight bleeding through our translucent white tent cloth (some other radios at the same location had displays that were almost impossible to see)

- the ATU did was able to tune a narrow-banded 20 meter yagi on other bands, when necessary, including 15, 10, and 6 meters

- the radio ran from a very small Li-Ion battery (KXBT2, ~2.5 AH) for quite awhile, proving it works at 11 V, which is important for stations running from a somewhat depleted car battery or other emergency supply

- operators were very complimentary of the internal speaker, though I'm partial to stereo audio and was using a pair of 8", 4 ohm (passive) external speakers most of the time

We had a bit of fun late in the afternoon on Saturday when we switched from the Yagi to an AX1, Elecraft's 4 foot 20 meter whip. This may seem frivolous, but it's an important test because it shows that the radio's shielding is working well. It should handle an end-fed wire with a balun right at the antenna jack.

Here are some comments we received afterward from KJ6K:

"It was a real thrill to play with the K4 while making making CW contacts with it during Field Day. It's an amazing technical and usability design achievement. The user interface for many modern radios is so complex that an operator may need to refer to the manual frequently to figure out how to access a desired function, and never be able to do so quickly. The display on the K4 is gorgeous, and the use of touch, along with physical controls, provides a very intuitive and efficient user interface.

"My own interests in ham radio have always been mostly in the science and engineering, so my operating is mostly casual, with HF CW my favorite mode. The architecture of the K4 is really exciting; the performance and endless possibilities for features and connectivity is really cool."

Thanks, John!

Looking forward to full-contact Field Day battle mode with a couple of K4s next year :)

Re: K4 Field Day report

Hopefully there will be a lot of them in users hands by then (MINE)!!

Thanks for the update.

Re: K4 Field Day report

In reply to this post by wayne burdick

I'd be interested to hear how it does in the presence of close in strong
signals, especially SSB. I was operating a KX3 on SSB in close frequency to
someone that was far away, but they had all the knobs up to 11 and was
maybe S9+20 and about 10 kHz wide with lots of splatter. I could hear
anyone that came back to me but I eventually abandoned the frequency
because most could not hear me. 20 SSB was wall to wall with someone about
every 1.5 kHz or closer.

73,

Mark

Re: K4 Field Day report

In reply to this post by Mark Goldberg

There isn't a rig on the planet that will take out actual splatter,
although you MIGHT be able to filter out some of it at audio depending
upon the offender's voice characteristics. If the trash is truly within
your passband at RF you are going to hear it.

Most of that occurs due to sheer ignorance on the part of the operator,
but the sad thing is that there are hams out there who will
intentionally overdrive their rigs in order to create "elbow room" for
themselves. On CW they do it with fast rise times to generate key
clicks. I've seen posts from guys who admit doing it.

W3PIE on 14.080 FT8 was splattering prettybad yesterday morning. Spikes up and down the passband. Surely an overdrive issue with audio levels.

Great update Wayne

Well it's all relative.
Saturday, I got to FD, 2.5 hours from home, to a sister Clubs operation,
they invited me to come down and work some cw.
When I arrived, they were running an American rig (not Elecraft) on CW
station, I operated it for a few hours.

I asked if they minded if I ran my own radio, which was no problem.

I'm sure glad I brought my pelican case, with my trusty "old" k3 and p3,
no "s", no updates, no narrow filters, no nuttin!

It was like going from an HW-7 to a K2...

Sorry, but I'm ruined.

Have Elecraft, will travel.

I won't be moving to a k4... No need.

I'm happy.

73 all

Re: K4 Field Day report

Definitely W3PIE

I kept sending W3PIE CK LEVELS but guess they didn't know what they were
looking at. You could see the spikes across their whole TX passband and
noise floor rise.
