Multiple KUSB Connects

In a multiple Elecraft device station, I’m curious if anyone connects all KUSBs to a USB hub semi-permanently so that when you need a connection you already have that hardware access? Realizing you cannot run two Utility programs simultaneously (at least I haven’t had success with that), what is your setup? I have attempted with a USB hub into a Mac Mini with marginal success. Please opine.

Re: Multiple KUSB Connects

I use either an Edgeport 8-port USB to serial adapter, or a Gearmo 4-port USB to serial adapter, or a KUSB or KXUSB depending on what I'm testing.
No USB hubs here, tho.

Hmm .. I've not tried that. I'd be cautious trying
it. Really no need, after all.

Hi to the group again
I have a USB hub with a USB to rs232 for my K3 and another for my KX3. I have never tried to run both at the same time but they have both been on the same hub for 2 years and they always work, Port 4 for one, Port 7 for the other and Port 5 for the WinKeyer USB which I know works at the same time as the KX3.

Again hope I did not waste band width but thought my experiance would help.

Re: Multiple KUSB Connects

In reply to this post by Phil Wheeler-2

Yes, Phil, you’re probably right. Probably over-think here. But there are KAT500 parameters that can be more easily managed in real time with the KAT500 Utility, so I thought I’d give it a try. Dunno, in the bigger picture, might this be he precursor to the idea of software control or software monitoring of Elecraft devices? Maybe. My problem is when I connect five KUSBs they all have 10-or-12-digit names that I have to go through manually to find my device that I want to control (I know, I know, poor me!!!). AND they are power hogs. Mac OS X shuts ‘em down: too much power suck combined. So, you need a powered USB hub to connect a few.

Re: Multiple KUSB Connects

Works just fine for me. I use a powered USB hub. A standard USB port can deliver a maximum of 500 mA for USB2 ports, or 750mA for USB ports. That should power a lot of USB-Serial ports, but as they say, your mileage may vary.

I use an FTDI four-port USB adapter (it’s a development device from Mouser). OS X nicely identifies each port as the serial number followed by A, B, C or D. I also use several single-port FTDI devices and note their id numbers so that I can associate them with what they are connected to. All work pretty well. They are connected as follows to my 2009-vintage Mac mini: The four-port device plugs directly into the mini, while the other ports plug into a 7-port powered USB hub. I need at least five to communicate with various Elecraft devices, and actually can run multiple device Utility programs simultaneously. We don’t recommend that folks do that, but it works for me.

By the way, my worst-case test used a total of nine FTDI USB-Serial adapters with the mini. All worked quite well, used with several different applications running concurrently. So, it will work.

In reply to this post by David Ahrendts

No problem here with my Timewave Navigator which is a 6 port USB hub to
CAT, PTT, FSK, WinKeyer, Config, and an fully configured RS232 which
connects to my KPA500. Cheaper USB hubs, Logitech etc. exhibit RF
sensitivity but then all of my antennas are in the attic as I live in a
CC&R subdivision.

Re: Multiple KUSB Connects

My friends, thank you for your many responses to this question. Clearly I’m not the only one thinking of multiple semi-permnanent KUSB connections to multiple Elecraft devices simultaneously. Lesson: all things are not equal when you select a USB powered hub.

Among the responses that I found most valuable was this one sent directly from N1HO, Bayard R. “Brandy” Coolidge — much thought has been put into his USB to Mac setup — sharing it here with everyone:

I just upgraded my shack from an Acer Netbook (1.66 GHz 32-bit,
2GB memory) to an early 2015 Macbook Pro Retina 13" at 2.7GHz
with 16GB memory (and 250GB of SSD). I had used a powered USB hub
from an "office superstore" that ran at USB 2.0 speeds, and had
Sabrent USB/serial cables (which explicitly use FTDI chips) running
to the K3 command port, the KPC 3+ (which went to another rig for
VHF packet use), the Trimble Thunderbolt GPSDO's NMEA port, plus
the SignaLink USB's cable.

When I upgraded to the Mac, I also shucked the old USB hub in favor
of a Sabrent 4-port USB3 hub. I'm running Windows 7 Home Premium under
Parallels 10, and the Mac is running Yosemite with all the latest updates.
(The Acer Netbook ran Windows 7 Starter). I've had this setup running
for a couple of weeks now, and I'm extremely pleased. In fact, just
yesterday I swapped out the SignaLink for an Asus Xonar U5 sound card,
which Jim, K9YC recommended on the list - it works perfectly. Last night, I
was able to take the rMBP, an old Alinco handheld, the KPC3+, the
special cable to run from the Alinco to the KPC3+ and one of the USB
cables with me to an ARES meeting. It all plugged in and played WITHOUT
having to fuss with COM port designations, etc., etc. Came home, spent
5 minutes (maybe) reconnecting everything and all came up smiling.

That said, I don't quite know what to tell you except that one thing
that helped maintain some sanity with my old hardware configuration
was to mark each and every cable and every USB hub port and never, ever
plug them in "wrong". Otherwise, Windows would go off and assign a new
COM port number to a given cable and I'd end up chasing my tail. I'm a
retired UNIX software QC engineer, so my tolerance for that sort of
baloney is minimal. One thing that bit me frequently, and took me months
to finally nail down, was that for whatever reason, Windows would insist
on spontaneously downloading, installing, and running a Ballpoint Pen
device driver for the Thunderbolt, basically taking over for the mouse,
resulting in all kinds of cursor movement and "clicks". I had to figure
out how to outfox it, get into Device Manager and disable that driver.
I later found a brief discussion on the Time-Nuts mailing list about it,
and a few other guys had had the same problem and disabling under DM was
apparently the only viable solution. (The Thunderbolt runs at 4800 baud).

That said, I've been amazed that I was able to pull everything last night,
go to the meeting with just the KPC3+ and then reassemble perfectly. Since
you're going to be dealing with multiple K3s, and will probably want to
run them both/all at 38400, you may go nuts trying to figure out which is
which. Remember that the K3 Utility does display the serial number in the
title bar, and you'll need to assign a different COM port for each rig,
so I think some patient labelling and record keeping could help there. I
rarely run the Utility anyway - only long enough to download and install
firmware - so I don't (personally) see the need to run two copies
simultaneously. However, you will need to figure out how/where to store
the configuration files for each rig separately; I can't remember what the
normal default file locations are offhand. But it should be possible to
bring up the Utility and manually change its COM port so that it's talking
to Rig B instead of Rig A. (Or there may be a configuration file for the
Utility as well, so that it knows what COM port, etc. to use or it may be
possible to invoke a specific COM port on the command line, in which case
you could create two desktop shortcuts, one pointing to one rig's COM port,
the other to the other - Lady Heather, the control program for the GPSDO
does that, as do many other applications). BTW, under Parallels, you can
force it to grab the various ports, including the external "sound card",
away from OS X and assign them quasi-permanently to Windows, so that Windows
will always be able to drive those devices.

Again, I'm NOT a Windows expert, but I do hope that this provides some clues,
and if you have further questions, please feel free to e-mail me, and I'll
try to help.

Very 73,

Bayard R. "Brandy" Coolidge, N1HO

Re: Multiple KUSB Connects

Just took delivery of the KUSB for the KPA500. Discovered I am up to speed on FW and saved the config. Left the KUSB connected. Did a 30W K3S tune up and EVERY RED LIGHT on the KPA500 came on. Awesome experience. Sorta like LA’s notorious 405 most nights! Checked everything. Did a quick 30W tune transmission again. KAT500 says 1:1.2 or less. W2, the same. RED LIGHT city again on the KPA500. Removed the cable and we return to sweet green all around.
So: ya don’t operate the KPA500 with the KUSB attached, right?

Re: Multiple KUSB Connects

Interesting, Jack. K3S to KPA500 to KAT500 and a W2 to MA5B typically 1:1.2. Perfecto!
Connected the just received KUSB-KPA500 cable to the amp and to a USB port on my Apple Thunderbolt 27.5 display running with the MacMini.
Downloaded KAT500 Utility and checked to see I have current firmware. I did. Saved the config. Left the cable in place.
Did a low power (amp in stand-by/amp in stand-by) 20M tune just to check if the KAT500 needed to adjust. Every red light lit up on the amp. Did not dare engage high power. No red lights on the KAT500 or the W2.
Removed the KUSB cable and all was back to normal.
Has to be RF traveling back through the new cable to the KPA500. Let me duplicate the situation again taking great care to separate the KUSB cable from any coax, and I’ll report back.

Re: Multiple KUSB Connects

Welcome to the world of high power. You will find a lot of things in your shack may not be designed to handle the higher power you now can run.
For example, take a good look at the specs for your MA5B. It is rated at 350 watts key down for any length of time, further rated at 600 watts CW,
with a low duty cycle. Make sure that all cables and connectors in the antenna path are rated for the higher power you now run. You might want
to add a good RF Choke to the MA5B to eliminate problems with RF on the outside of the coax shield. K9YC has a very good tutorial for this.
See: http://audiosystemsgroup.com/RFI-Ham.pdf <http://audiosystemsgroup.com/RFI-Ham.pdf>
Take a good look at some of the other things in your shack that also might benefit from good choking. The USB cables will be included in this,
especially the one from the computer to the KPA500.

The problem you are seeing isn’t too hard to resolve, but it will take some patience and experimenting to take care of them. There are a lot of us
on the reflector who have been through this who can help with suggestions. And realize that what you saw was not normal, but is actually not
a problem in the amplifier or radio. It’s just a result of using them. Once you get them licked, things become a lot more fun!

I've never considered doing this. Except when there's development for
brand new products, Elecraft firmware typically updates once or twice a
year. We're seeing a bit more than that now because of the new K3S and
P3TXMon.

At home, I use real hardware RS232 to control the two K3s looped through
P3s in my SO2R station. That works with K3 Utility, P3 Utility, N1MM+,
WSJT-X, and DXLab Commander. The only control lines to my KPA500 and
KAT500s are PTT via the RCA connectors.

Both the KPA500 and KAT500s are very good at RF-sensing to do their own
band-switching. I use their USB connections only when I want to load new
firmware, and I do it by simply moving a USB cable from one unit to
another. I use the AUX bus only to feed band decoders for switching
antennas and bandpass filters.

For FD and CQP, I find myself using the USB cables because the computers
don't have hardware serial ports.

73, Jim K9YC

Re: Multiple KUSB Connects

The advantage of connecting the KPA500 to the K3[S] is that you can
select bands with one button. Useful for those of us who forget what
band we wanted as we're stepping through them with the BAND UP/DOWN switch.

Re: Multiple KUSB Connects

In reply to this post by Jack Brindle-2

Jack, reporting back, as promised:
I could not replicate my red light experience tonight. Carefully keeping the KUSAB-KPA500 cable well away from any coax, I connected as I did yesterday to the Apple display and Mac Mini.
Did a TEN WATT xmit (KPA500 in stand-by). All green lights. Same for 20 watts.
Engaged OPER at 25 watts. Produced 500 watts from the KPA500. Smooth as silk.
I clearly laid the KUSB right smack on top of the power out coax. No other explanation.
So, case closed.

And in the words of the very wise moderator of this list, Eric Swartz, (he’s thinking of this right now), “let’s close this discussion on Multiple USB Connects.” Thanks much. Thread closed.

Awesome experience. Sorta like LA’s notorious 405 most nights! Checked everything. Did a quick 30W tune transmission again. KAT500 says 1:1.2 or less. W2, the same. RED LIGHT city again on the KPA500. Removed the cable and we return to sweet green all around.

Loaded K3 for sale

In reply to this post by David Ahrendts

I'm ordering a K3S and, therefore, I'm selling my loaded K3/100:

*KAT3 auto tuner
*KRX3 second receiver
*KXV3A I/O board
*KDVR3 voice recorder
*KFL3A-400hz and KFL3A-1.8kz 8 pole filters in main receiver
*The base unit filters in both receivers have also been upgraded to the KFLA-2.8 8 pole filters

In exceptionally clean and 100% operating condition. Two months ago the rig was at the factory for repair of the KRX3, it was returned and the technician notes said that the rig checked out as meeting all specs. Unit was new in July 2013, Serial Number 7561. Asking $3200. Greatly prefer PayPal for payment.

If interested, please contact me off list.

73,

Re: Loaded K3 for sale

I left off two other accessories: general coverage RX board and TCXO. These were added more recently and I forgot to add them to the list.
