KPA-1500 s/n 56
Locked
 
|
I received my KPA-1500 s/n 56 last Friday and have it on the air. All
is well with the exception of not being able to use the KPA-1500 Utility. I do not get a notification sound from the computer when I plug the USB cable into the computer. I've reset the KPA-1500, tried different USB ports, no success. Any suggestions appreciated.

I’d suggest using the Windows Device Manager to view COM ports, see what COMn gets added when you unplug and plug in the USB cable from the amp. If none change, it might be a device driver needed. Usually Windows finds this driver automatically if needed, but sometimes you need to reinstall the driver. There is a link to the FTDI driver website on the page for KPA1500 Utility. There may be advice in the KPA1500 utility help text under troubleshooting.
The USB port is used for factory burn in software, so it was working at least at that time. If you can’t get it quickly, contact Elecraft support, they probably have a better checklist than I do. 73 de Dick, K6KR > On Apr 1, 2018, at 11:43, Ed Gilliland <[hidden email]> wrote: > > I received my KPA-1500 s/n 56 last Friday and have it on the air.

When running the KPA1500 at full power, sometimes the power will fluctuate. EXAMPLE: I was checking in to the Elecraft SSB net a little while ago. While transmitting, the power dropped to around 400W. This has happened on 20M CW as well. I wonder if the K3S output is dropping. (??).
If I run at 500W or so, no problem. Carl Yaffey K8NU Recording studio.

Thanks Dick,
That's the first thing I did Dick but nothing on the Windows Device Manager changes and there is no notification sound that you usually get when unplugging/plugging a device into a USB port. I wonder if the USB port in the KPA-1500 is dead. I reinstalled the FTDI driver, no help. I uninstalled/reinstalled the KPA-1500 Utility, no help. The KPA-1500 Manual under Troubleshooting suggests the Windows Device Manager, unplugging/plugging the USB cable method to locate the proper com port. I've run out of talent...hi! I'll send a note to Elecraft Support.

I replaced the USB cable with a known good cable, no help.
I am using the K3s. I neglected to order the AUX cable when I ordered the amp but since have placed one on order and should be here tomorrow but I don't think it will help in this case. Maybe Elecraft Support will have an answer. I REALLY don't want to send the amp back to Elecraft. 73, Ed On 4/1/2018 16:22, Dick Dievendorff wrote: > OK, we tried! > > Any spare USB A to USB B cables around that you can try?

I would expect you did a restart and went back to the Dick's suggestions? It is a PC issue. What version? Anti-virus program?

Note the one item I have as failed. If you find the same on your machine, simply quick uninstall, then go to the top tool bar and click on action and scan for hardware changes. The snippet tool won't let me copy to point it out to you. See if that doesn't do it. So, to summarize, Device manager, click on the Universal Serial Bus Controllers, right click on marked USB devices marked with a fault indicator and then uninstall each of them, then go up to menu and then scan for changes. That should do it. Of course, you have to select the correct port when using the utility, and try each one to be sure you have the correct port!

Ed,
Can you connect the K3 Utility to your K3S using the USB cable supplied with the K3S? If not then it sounds like you have a FTDI driver issue. http://www.ftdichip.com/Drivers/VCP.htm http://www.ftdichip.com/Support/Documents/InstallGuides.htm If the K3S connects to the K3 Utility then please send an e-mail to < [hidden email]> letting them know your KPA1500 USB issues. 73 Howard K6IA ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |

Hi Bill,
Thanks for the reply. I'm using Windows 10 Pro, Windows Defender. I thought that you had nailed it. I checked the Allowed Apps in Windows Defender and the KPA-1500 Utility wasn't listed. I added it and restarted the computer, no help. Shouldn't I hear a notification sound when I plug/unplug the KPA-1500 USB cable. I do when I unplug/plug the keyboard.

You might try removing the USB connector, Restart, check the device manager, if a device isn't linked, remove it , then plug in the USB. If that doesn't connect, remove it again, and then sort through the comports in the utility and if that doesn't work, you may have different problem. I suspect your issue is within your PC not the amp. Let me know.

Carl,
I haven't seen any responses to your question -- have you determined anything further by now? Assume you're not using ALC hook up? 73, Roy K6XK "When running the KPA1500 at full power, sometimes the power will fluctuate. EXAMPLE: I was checking in to the Elecraft SSB net a little while ago. While transmitting, the power dropped to around 400W. This has happened on 20M CW as well. I wonder if the K3S output is dropping. (??). If I run at 500W or so, no problem."

I have not experienced any of this type problem. I have my CONFIG:PWR SET to PER BAND so that the K3s switches power levels depending on if the KPA1500 is OP/STNBY. Since you are saying this depends on your output power then would first look for RF feedback issues. Are you using the Aux cable between K3s/KPA1500?

Ed,
Did you ever install any Prolific USB devices in your system? Prolific Device Drivers are buggy and can often interfere with the FTDI drivers. Prolific Device Drivers can be uninstalled. You can use the free USBDeview facility to look for this: https://www.nirsoft.net/utils/usb_devices_view.html Scroll down to the bottom of the page and click to download the 64-bit version, (direct link https://www.nirsoft.net/utils/usbdeview-x64.zip). Unzip to empty directory, then run usbdeview.exe. Scroll way over to the right and click on the column header "Device Mfg" to sort by that column. Look for "Prolific" in the list. Right click and uninstall. Then reboot and reconnect the USB cable to the KPA1500. If it's still not recognized, you may have a bad USB port on your amp. 73, Bob, N6TV On Sun, Apr 1, 2018 at 11:43 AM, Ed Gilliland <[hidden email]> wrote: > I received my KPA-1500 s/n 56 last Friday and have it on the air.

Another possibility, especially if you are reaching behind the KPA1500 to
insert the USB cable, and can't see the connectors well, is that you've accidentally pushed the square USB-B plug it into the square RJ-45 (Ethernet) connector instead of into the USB-B connector which is just above it. 73, Bob, N6TV On Mon, Apr 2, 2018 at 8:55 PM, Bob Wilson, N6TV <[hidden email]> wrote: > Ed, > > Did you ever install any Prolific USB devices in your system?

Thanks Bob,
I looked at the USB-B connector again, unplugged from the WinKeyer and plugged into the KPA1500, no virtual port was created. Elecraft agrees with you about the USB chip being bad. They've sent me an RSA so the amp will go back for service. I asked if we could do a board swap but they have other mods to make to the RF deck and that they will give the amp top priority repair status. I used USBDeview, no PROLIFIC drivers and the three COM ports listed are all using FTDI drivers. Nice utility, thanks. 73, Ed On 4/3/2018 04:37, Bob Wilson, N6TV wrote: > Another possibility, especially if you are reaching behind the KPA1500 > to insert the USB cable, and can't see the connectors well, is that > you've accidentally pushed the square USB-B plug it into the square > RJ-45 (Ethernet) connector instead of into the USB-B connector which > is just above it. > > 73, > Bob, N6TV > > On Mon, Apr 2, 2018 at 8:55 PM, Bob Wilson, N6TV <[hidden email] > <mailto:[hidden email]>> wrote: > > Ed, > > Did you ever install any Prolific USB devices in your system? > Prolific Device Drivers are buggy and can often interfere with the > FTDI drivers.
