[Elecraft] Announcing the new Serial Box USB with built-in FTDI USB-to-Serial adapter

2018-08-10 Thread Bob Wilson, N6TV
"The Serial Box" (S-BOX) is intended to be the "Swiss Army Knife" of
interface boxes, with many possible configurations and uses, for both
Elecraft and non-Elecraft gear alike.

The S-BOX is now available in a new model, the Serial Box USB (S-BOX-USB),
which has a genuine FTDI USB-to-Serial adapter built in, providing a single
virtual serial port.

See https://bit.ly/S-BOX for new photos, details, and pricing.  A
compatible USB cable is included with every new S-BOX-USB ordered.

The original S-BOX remains in production and may be ordered instead, if you
already have an FTDI USB-to-Serial adapter, or enough real serial ports
available for rig control and keying.

To review, both models eliminate serial Y-cable confusion and complexity.
They make it particularly easy to connect any modern transceiver to *both* your
computer *and* an Elecraft / SPE  / ACOM amplifier *and* a SteppIR
controller / KRC2 / ShackMaster SM-8, all at the same time, with automatic
band changes for all connected devices, and no serial port "collisions."

Both the S-BOX and S-BOX-USB can be used to connect a PC or MAC to the KX2,
KX3, K3, or K3S.  They also can be used to connect the KPA500 and KPA1500
to a KX2, KX3, and most non-Elecraft transceivers, with automatic band
switching.  KUSB, KXSER, KXUSB, or KX2ACBL?  Not really needed if you have
an S-BOX.  Economical phono and standard serial cables can do it all, no
soldering required.

The four open-collector keying circuits inside the S-BOX provide
computer-generated CW, FSK, and PTT keying to one or two transceivers, with
good timing, even when using a USB connection (if FTDI, not Prolific).
This works with any transceiver, including the KX2 and KX3, which do not
provide internal CW keying circuits like the K3 and K3S.

Finally, RemoteHams software users are finding it especially convenient to
use the S-BOX to remotely power up a K3 and amplifier, using the "Use RTS
as Power" feature built-in to the RemoteHams RCForb
 software -- RemoteRig hardware is *not*
 required.

For the latest eHam.net reviews of the S-BOX, see:

Thanks for your support.

[Elecraft] Problem with using a muffin fan on top of a KPA1500

2018-08-10 Thread Wayne Burdick
A muffin fan (or other large fan) placed on top of the KPA1500 will, of course, 
cool the heat sink. However, it will also delay or even prevent onset of the 
amplifier's own fans. 

This is a problem because the amp's fans cool both the heat sink *and* the 
interior of the amplifier. Due to the power levels involved, many components on 
the PC boards require cooling, including low-pass filter inductors, relays, and 
high-wattage resistors in the T/R switch and attenuator.

Please do not use external fans to cool the amplifier's heat sink.

73,
Wayne

Re: [Elecraft] HRD slow accessing K3 frequency controls

2018-08-10 Thread Joe Subich, W4TV


Note: The K3/K3S Programmers Reference specifically states that the FA;
command (change frequency) requires  0.5 seconds when changing bands and
that *all command handling is deferred until the process is complete*.

I don't know if band changes enter into the equation for you but if an
earlier version of HRD operated correctly and the current version does
not, the fault would appear to lie with HRD.  I suggest you raise a bug
report with HRD LLC either through their support organization, if you
have a current support subscription or via the HRD Support forum
 if you are not a current subscriber.

HRD LLC released 6.4.0.876 yesterday.

   ... Joe, W4TV

Got it!  It was suggested in an email that I install an old version of 
HRD. I did that (5.24.xxx) and sure enough - all is working just fine now.


Question is:

Is it the fault of a Windows update?

Is it the fault of an updated version of HRD.

Fact is:

It is not the fault of the K3!

The jury of users can figure the rest out - I will merely run the old 
version of HRD and enjoy it.

Re: [Elecraft] KPA1500 - adding fans

2018-08-10 Thread Jeff Blaine
The kind of noise the amp makes is related to but a separate issue to 
the loudness.  Last night I was doing some comparison listening while 
trying to find some DX on 20m and noticed that while the FAN2 setting 
was definitely louder than FAN1, it seems a more "pleasant" noise 
compared to FAN1 which tends to have some sort of a sequel-type note to 
the sound it makes.

[Elecraft] Aged K3 - connector replacement

2018-08-10 Thread Tom Boucher
After deliberating for years about my ability to change the 28 way
motherboard to front panel connector on my 10 year old K3 for a gold plated
one, I finally plucked up the courage and did the job in about 2 hours.
Elecraft supplied me with a replacement connector some years ago. I have to
say it was a lot easier than I expected and hopefully will now perform
without all sorts of random faults being displayed and regular removal and
re-fitting of the front panel.

So if, like me, you are not sure about doing the job, remove the front
panel and top and front bottom panels to give maximum access. Remove the
old connector by snipping the plastic between each pin one at a time, use a
solder sucker and hold the pin while removing it with a small croc clip.
When they are all out, clean solder out of all the holes with fine
solder-wick braid and flux. The new connector should then push into place.
Re-solder on the opposite side of the board to the connector and the solder
will flow through and around each pin.

My K3 appears to be working perfectly now, so am hoping it will now stay
that way!

I also used a QC15 and then moved to the QC25 and found that either is a very 
comfortable headset to wear for long periods of time.  The little microphone 
that “dangles” in the cord actually works quite well with both the K3s and KX3 
in most surroundings.  All that it requires is a good TRRS jack to two TRS male

 I have tried a couple of the add on boom mics but I prefer to use my desk

[Elecraft] Noise cancelling headphones

2018-08-10 Thread Mike Kasrich
I've used the QC-15 and the are good. I had a headset buddy but the boom 
was "limp" it worked. I have a Uflymic for the QC15 if anyone has an 
interest.



My choice now is the Bose QC25 and modmic by Antlion.  The QC25 has been 
replaced by the QC35 so you can get a "25" in an affordable range.

Re: [Elecraft] KPA1500 - adding fans

2018-08-10 Thread Richard Zalewski
Very good info Tony.  Saves me the experiment.  I think it also shows that
the guys at Elecraft did a good job in cooling design.

[Elecraft] KPA1500 - adding fans

2018-08-10 Thread N2TK, Tony
For the heck of it brought my KPA1500 from the basement to the shack desk. Ran 
a test with 10 CQ’s on 6M with 1K out on FT8. By the time the CQ’s were done 
the amp temp was up to about 75C. The amp is set so the fan is always on at #1.
Added two 4” 110VAC fans in series to cut down the speed and noise and covered 
the exhaust holes on the top of the amp to extract air. Then I tried with just 
one 4” fan in the center running full speed. Bottom line there was virtually no 
difference in the top temp of the amp with these settings. 
I know, not very scientific. Just seeing if there would be a noticeable 
difference with adding fans.
Time to move the amp back to the basement. I never hear my amps ☺
73,
N2TK, Tony

Re: [Elecraft] HRD slow accessing K3 frequency controls

2018-08-10 Thread Bill

I will amend the above:

It is not the fault of MY K3.

Re: [Elecraft] HRD slow accessing K3 frequency controls

2018-08-10 Thread Bill
Got it!  It was suggested in an email that I install an old version of 
HRD. I did that (5.24.xxx) and sure enough - all is working just fine now.


Question is:

Is it the fault of a Windows update?

Is it the fault of an updated version of HRD.

Fact is:

It is not the fault of the K3!

The jury of users can figure the rest out - I will merely run the old 
version of HRD and enjoy it.

Re: [Elecraft] HRD slow accessing K3 frequency controls

2018-08-10 Thread Bill

Also have noticed that when using the K-Pod to QSY:

HRD is very slow to report the current frequency and cannot keep up with 
the VFO. The K3 display works properly with the K-Pod.

Bill,
Please let me know if you see slow comms between the K3 and otehr 
programs.  I am seeing that in some cases.


73s and thanks,

prior postings)
K3 is fully updated and no connection changes have been made in over 6 
months except to test

  (replaced all lines for testing purposes)
K3 is currently operated using a Genovation and K-Pod - works wonderful!!!

At this point I am done wasting time on using HRD for the K3. For 
whatever reason, it does not perform as I expect. I can use it - just 
not expect to do multiple QSYs at a fast pace (such as checking various 
net frequencies quickly). Others mileage may vary.
