Re: K4???

Agreed. I will just happily keep using my K3 until I get a "still want
this order" from Elecraft. Then I will eagerly away the box(es).

Re: K4???

In reply to this post by wayne burdick

Wayne,

quick question ... I am giving very serious consideration to a K4, but
the kit version. Assuming the new timeline on the factory version
works out, should we expect a kit by Sept 2021?

Thanks,

Neil, KN3ILZ

Re: K4???

Historically, they spend couple weeks to a month to get the steps worked out on their production line. Then finalize the assembly manual. So usually the kits are about 4 to 6 weeks after factory built. YMMV!

Re: K4 Kit???

Yep, just more fun to "build" one eh?

Actually, I'm just plain "Cheap" and hoping to save a few bucks on a kit
version.
However, recent Elecraft kits are more like erector sets, but I DID build a
K2 complete with soldering stuff.

Re: K4 Kit???

Administrator

We certainly appreciate the interest in a K4 kit. It does take longer to get the kit version out since many new drawings are required to accurately communicate details on modules, cables, and hardware to builders (as opposed to in-house assembly personnel). Can't really put a date on the kit version at this time, but it will be well after we begin shipping the K4 and K4D.

There's an intermediate approach that many of our customers have used over the years: get an assembled basic radio, then install option modules yourself as required and as time/availability permits. Option modules will come with detailed assembly instructions.

Some will be, including the KAT4, KPA4, and KRX4 (the latter is what turns a K4 into a K4D). But customer-installation docs take some extra time. Our documenters are busy as beavers working on the owner's manual. (I don't mean chewing it, though a printed copy would be a good source of fiber.)

Re: K4 Kit???

In reply to this post by wayne burdick

Or you can do what I did with my K3: burn up a static drain resistor on
your antenna entrance panel, decide that the smell is coming from the
K4, take it completely to pieces to try to find the burned
component, and then -- after discovering what actually happened -- put
it all back together again.

Can you give a rough estimate of how many parts there are in a K4
compared to a K3? About the same? More? Less? (More parts = more fun.)

Re: K4 Kit???

I believe Elecraft equipment has static drains built in but I always put
a resistor in a PL-259 plugged into one arm of a coax tee with the
antenna on the other arm, on the connector on the radio. It doesn't
have to be precipitating to create "precipitation static" and it won't
take long for those infinitesimal little charges to fill up the input
capacitance on the first RF stage.

Re: K4 Kit???

ICE lightning arrestors include a static drain. I think the ones now made
by Morgan Mfg. and Array Solutions do too, but haven't confirmed that.

Hi Drew,

Rather than a parts count -- an esoteric parameter I get paid to worry about -- I'll give you a qualitative breakdown.

Even a basic K4 is the equivalent of:

K3S +
P3 +
KRX3 (for dual-watch purposes) +
KXV3 +
KDVR3 +
Linux/Intel MPU +
large touch screen +
external monitor adapter (like P3 SVGA, but HDMI)

+ more controls, more antenna jacks, more digital I/O ports, and all the DSP/ADC/DAC/FPGA hardware needed to create a modern SDR. It also has a multi-processor architecture with unlimited potential for future expansion.

Of course there are economies related to it being an SDR, such as no crystal filters in the basic unit.

From this you could take an educated guess.

Can't really put a date on the kit version at this time, but it will be well after we begin shipping the K4 and K4D.

Re: K4 Kit???

In reply to this post by W2xj

Not in my experience. Chokes are inductors and, together with stray
capacitance, can create unwanted resonances and accompanying
parasitics. Resistors just bleed the charge off an otherwise nearly
infinite input impedance which is the whole idea in the first place.

**"Nearly infinite" is not a really good term mathematically, but it's
short and conveys the idea
