The source code is available for cocoaModem but the developer hasn't supported 
the program in quite some time.

Macs as supplied with OS 10.14 and above could have a problem with cocoaModem - 
which is an excellent program for dual receive split RTTY operation.

So it's more than just which Mac to get, it's will the machine run the 
applications you want to run.

If anyone has run cocoaModem under 10.13 or 10.14 please report.

Re: [Elecraft] Best Mac to use with KX3

[Jack Brindle via Elecraft]

WSJT-X runs just fine on my 2010 Mac mini with a core-2 duo processor. Almost 
every Mac that runs an Intel processor has at least a Core-2 Duo (the exception 
being the very first Intel iMac that used a single core Core-2 processor).
I would not want to use a Mac with a sub 2 GHz processor - the low end MacBook 
Air and last generation low-end mini come to mind here. Everything else should 
be prime for a shack computer. 

If you plan on running VMware Fusion, Parallels or VirtualBox you want a 
powerful Mac with at least two cores, the more the better. Give the Mac at 
least one of those and Windows as many as you can. You don’t want to starve 
either OS since both are running simultaneously.
My choice at this time to replace my shack mini (which is constrained to El 
Capitan) will be a 6-Core i7 mini with 16GB or Ram (don’t scrimp here) and 1TB 
of flash disk. It will last a long time, so putting extra money into it up 
front is a good thing. If Apple were to release an 8-Core i9 version of the 
mini that would be my choice instead…
On the laptop side, my choice was a 15” MacBook Pro with 4-core i7, 16GB memory 
and 500GB flash. Again, don’t scrimp. If it follows the pattern of my last 
MacBook Pro, this baby will last me eight years or so (the old one, constrained 
to El Capitan is still in use as a server).

Basically, get as much horsepower as you can afford. That means lots of cores 
in the processor, lots of RAM, and a reasonable amount of flash. 256GB is a 
minimum here. Macs last a long time, so you are making an investment for the 
long term.

Good luck and enjoy your Mac!

Jack, W6FB

Re: [Elecraft] Best Mac to use with KX3

[Walter Underwood]

The only program that requires significant CPU is WSJT-X, for JT65 and FT8. The 
fldigi program might needs more CPU for some modes, but I’ve never noticed it. 
Macs usually have very high performance hardware for the year when they are 
released. I would expect any Mac from the last five years or so to work fine.

Re: [Elecraft] KAT500 Utility Operate -> Memorize

[Dick Dievendorff]

See KAT500 Utility help.

ATU settings found by tune are stored without pressing the button.  If you 
create an atu setting yourself, using the radio buttons for inductors and 
capacitors, you can save it with that button.

Re: [Elecraft] CM500 Mic ?

[Nr4c]

The packaging used to say “Dynamic” mic. But it’s not. It’s an electret. 

And it comes with a small battery box to provide the bias when using with 
radios that don’t provide bias on the audio jack.

Re: [Elecraft] KAT500 Utility Operate -> Memorize

[Bob McGraw K4TAX]

The tuner will memorize the antenna selection and matching elements 
every time it tunes.


As to the Utility, what ever you change in the Utility will be be sent 
to the tuner when Memorize is selected.     Not it is not necessary to 
hit Memorize every time the tuner resolves a match.

Re: [Elecraft] CM500 Mic ?

Yes but..when one looks at the SPECS  one will see "Microphone

Re: [Elecraft] FW: [Elecraft-K3] K3S Comparison table finalized (linkattached)

[Jamie WW3S]

and that was my real life experience in last weekends 160 contestI felt 
the 7610 could hear just a bit better than the K3, especially those ESP 
signals right at the noise.I worked several DX I wouldn’t have with the 
K3.BUT...in crowded condx, the 7610 thumped and pumped when someone 
was close to my passband, even with a 200 hz filter enabled. I didn’t get 
any of that with the K3, its front end is like a brick wall..to be fair, 
I had the noise blanker enabled on the 7610, which some comments post 
contest said that could be some of the thumping I experienced.

I'd be interested in seeing a similar comparison of the K3S to the

That makes the K3S #1 and the 7610 #9 if you want to count for some

reason. The difference in 2 kHz dynamic range is 106 dB compared to 98 dB.

The table is sorted on 2 kHz IMDDR3. However, the table also shows dramatic
differences in blocking dynamic range. For example, the K3S is 20 to 30 dB
stronger in this regard than all of the direct-sampling radios in the table.
This is due to the K3S having narrow-band filtering (crystal filters) ahead
of the ADC. This can greatly reduce desense and other artifacts in any
high-signal situation (Field Day, KW neighbor, multi-TX station, etc.).

[Elecraft] Looking for ELECRAFT KBPF3A for my K3s

[Graziano Roccon (IW2NOY)]

Hello,

i am looking for a Elecraft KBPF3A for my K3s.
If anyone want to sell it or know someone that want to sell it, please 
let me know.
I would prefer in Italy or Europe, USA become too expensive for customs 
and shipment costs.


Thanks a lot, Graziano IW2NOY

[Elecraft] KX3/PX3/KXPA100 + accessories for sale

[David Orman]

Hi,

I have a KX3/PX3/KXPA100 combination I'd like to sell. I am the original
owner, and purchased all of the above in 8/2014. The KX3/PX3 was purchased
factory assembled, the KXPA100 was purchased as a kit, and assembled by me.
The KX3 is fully loaded, as you will see below, to include the 2m option.

All of the equipment is in excellent condition, and the PX3/KX3 have the
Side-KX options installed, including the plastic covers. The covers are in
good shape, with minor scratching as to be expected from plastic covers.
Photos are included below, with covers off/on.

In the interest of full disclosure, while performing the suggested
capacitor modification to improve the power-on delay on the PX3 (as guided
by Elecraft) a solder pad pulled up. This was repaired with a solder bridge
to the new capacitor in question, and the unit has functioned perfectly
since this time (April 2017). I am adjusting the requested price
accordingly, even though there is no impact to the performance or
functionality of this unit (and the power on delay is significantly
improved!)

I have included a video in the link below so you can see the PX3/KX3/KXPA100
functioning. I also adjust ref/scale and move around the band both via
radio and via PX3 in the video, so you can see it is functioning as
expected.

Everything else is exactly as delivered from Elecraft, and functioning
properly. The KX3 has had the full set of calibration performed on it, to
include extended temperature compensation, nulling, and filters, as I have
a bench of test equipment including a GPSDO locked signal generator.

Here's what I'm including, and current list pricing:

MH3 Hand Mic. for KX3
$59.95

KXFL3 Dual-Passband Roofing Filter
$149.95

KXAT3 ATU for the KX3
$199.95

KXPD3 Precision Keyer Paddle
$129.95

KXBC3 Int. NiMH Charger/Clk for KX3
$79.95

KX3-2M-AT 2M All-Mode Internal KX3 Option
$259.95

KXPACBL KX3 to KXPA100 Adapt. Cable
$49.95

KXPA100-K 100 W External Amplifier - Kit
$749.95

KXAT100 Internal ATU for KXPA100
$379.95

KX3-F 160-6 M Xcvrr Assm
$1,049.95

PX3-F Panadapter for KX3 - Factory Assembled
$599.95

XG50 Simple 49.380 MHz Signal Source
$39.95

SUBTOTAL $3,749.40

Keep in mind this subtotal does not include the Side-KX sides/covers. I am
also including the original sides for PX3/KX3 in case you wish to use them
instead. I do have the upgrade board for the paddle, as well, as well as
various tools/parts for the accessories. I am also including a few KXUSB
cables which currently list for $32.95. I'll also throw in the 2m antenna
seen attached to the radio in the photos.

KX3 serial number is 6755, PX3 is 0630, and KXPA100 is 1218.

---

I'm willing to sell the whole package for $2800 OBO.

My reason for selling is simple, I've moved to a pure desktop setup as I've
not found myself working remote as I had anticipated.

https://photos.app.goo.gl/g6rqVoXqF8i1FnL63 has photos and the video
showing operation, after which all were stored.

I live in San Antonio, TX and would prefer to arrange for local (you can
check it out in person) or regional pickup (happy to meet half-way). I have
batteries, so if meeting elsewhere, we can turn it all on so you can verify
operation if desired.

My call-sign is K5DJO, name is David Orman, please respond directly to my
email ( orma...@corenode.com ) and I'll pass you the rest of my contact
information so we can discuss via phone if you'd like! I can provide
additional photos/videos if requested.

Respectfully,
David Orman / K5DJO

Re: [Elecraft] CM500 Mic ?

[Walter Underwood]

If you are using a KX2 or KX3, you’ll get logic bias as well as mic bias on the 
CM500 mic. If you separate out the mic bias, you’ll get more and cleaner 
output. A stereo to L/R splitter will do that job, plus it breaks out the PTT 
line. I wrote that up on my blog.

I recall that it is Electrect.  Should plug in direct on the back panel

Re: [Elecraft] Last Click Serial Port

[Don Wilhelm]

Mike and all,

That is my experience with RJ45 plugs as well.  Rather than just pushing 
on the 'boot', it is helpful to pull the boot back a bit and push on the 
connector body itself, then slide the boot back in place.  That is true 
not only for the K3S RJ-45 connector, but any RJ-45 in my wired ethernet 
network.  Listen for that final click.

Since I have incurred a situation at lest 3 times on my K3S, since it might

the K3S when working an something and like a fool thinking when I put it all 
back together it is going to work first time.  I do have everything labeled so 
I do get everything into the right connector.  The problem I have had to arise 
several times, once everything is ready to check the, the RS232 serial port 
will not communicate.

After a lot of work each time it has turned out to be that the RJ45 connector 
for the RS232 jack, even though what appeared to be fully plugged in, pushing 
on it there would be a faint “click” signifying it is truly fully seated.  From 
where I thought I had it fully plugged in to actually being full could not have 
been a 64th of an inch if that. Not even sure if there is any further travel I 
just hear the faint click.  So if you use the RJ45, even though the RJ45 
appears to be in fully, if you have com port communication problems to your 
computer or cant talk to your P3, see if you hear that faint “last click” in 
the RJ45.  It is not just my particular K3S, I have seen the same situation on 
a second one.  73 Mike K4PI
