Re: [Elecraft] KPA-1500 s/n 56

[Bob Wilson, N6TV]

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

Re: [Elecraft] Firmware Update TM Command

[tomb18]

The command is useful for displaying the ALC level when you are using the radio 
remotely with appropriate software that supports it. Win4K3Suite will have this 
enabled in the next release. 73 Tom

Re: [Elecraft] Firmware Update TM Command

[David Box]

Bob

This is a macro command so does not appear in the config or menu.  Take 
a look at page 27 of the Programmer Ref.  You can use the command tester 
in the Utility to try it out.


Just for reference here is the Programmer Manual reference

TM (Transmit Meter Mode; GET/SET; K3/K3S only)
RSP format:  TM0;  (SWR/RF metering) or TM1;  (CMP/ALC metering). This 
sets the transmit meter mode for
the LCD bargraphs, as well as for the BG command (equivalent to using 
the METER switch). When TM0 is in
effect, BG returns the RF level. When TM1 is in effect, BG returns the 
ALC level.

Re: [Elecraft] K2/100 -- FT8

[Dennis Moore]

I use my K2-10 on digital modes. Haven't tried it with FT8 but it's fine 
with JT65, WSPR, RTTY. I installed the N0SS fixed audio output mod 
(http://www.farcircuits.net/w3fpr_K2%20audio%20Fix.pdf), didn't have the 
circuit board so used solderable perfboard.

[Elecraft] power varying - KPA1500

It is quite easy to determine if the K3S's output is dropping.

And, I suspect your no speaker out problem isn’t with the KIO3 board at all. 
It’s likely the audio speaker amp and it on a board in the front panel.

Re: [Elecraft] power varying - KPA1500

[David Box]

Carl

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?

Re: [Elecraft] The new KX19

Whilst I do understand that this was only a half day special offer, 
could you confirm that the anti-gravity mods reduced the inertial mass 
as well as either the local value of the gravitational constant or the 
gravitational mass?  My previous experience of such technology is that 
the device tries to disappear on a near parabolic orbit, except for 
being slightly limited by air resistance.
