Re: KPA500 "bypassed" when off?

Thanks. I was going to ask this question also, but forgot. It doesn't look like the K3S will display the power level from the KPA500 like the KXPA100 and KX3 combo does. Is that correct?

I have a new to me KPA500/KAT500 combo to go along with my K3S. I understand the standby and operate modes of the amp and the different power levels for each that the K3S can use. My question is will the KPA500 be bypassed when it is off and still use the KAT500 and the "standby" power setting on the K3S? I couldn't find anything in the manuals that mentioned this specifically. I did find one post that seems to indicate this, but it wasn't absolutely clear.

Here's a serious take on that. Note that a few details of the bonding of the protective earth to neutral is different in the UK. EVERYTHING else applies.

Re: Desensing issue

So, after taking the advice from group members...

I find that transmitting 400+ Watts into a dummy load does not reproduce the symptoms.
The noise floor is constant and the AF doesn't drop at all.
I presume that removes the radio, the amp and everything connected between out of the equation.

Next test will involve earthing before I am left with the assumption that the relatively closeness of the antenna causes my issue.

Re: Disabling Windows 10 Pro (and earlier) Automatic Updates

There is a Win10 utility called Windows Update Blocker (WUB), found at sordum.org. You can block updates and then enable them from this one utility. I usually turn off updates during heavy use, like weekend contests. Then, when I have nothing else pressing, I enable the updates at my convenience. I've had it left on for weeks, no ill effects.

I've been running Windows 10 Pro 64 bit since it was released.  A couple of points I find valuable:
(a) allow automatic updates to take place. I've not found this causes any issues or changes that result in misoperation.  If it does, it likely is due to something else in the system.   
(b) Perform regular computer maintenance to eliminate fragmented files, unused registry entries, and etc.   I use CCleaner for this purpose.  {The free version works but I prefer the paid version as it offers more features. }

The computer shut down procedure is VERY important.  Be sure to shut down the computer using the Windows supplied procedure and NOT by pressing the power switch.

I'm looking forward to Windows 11 like Windows 10 Pro 64 bit has given excellent and reliable performance.   I can't vouch for Windows 10 Home edition.

Re: Failure Notice

Hi Lou,

There are many versions of Linux which are called distributions or distros for short.  I would suggests starting with Zorin which is the most Windows like distro.

https://zorinos.com/

You can download and Linux distro on a thumb drive and run it "live" from the thumb drive without actually loading it on your hard drive.  This allows you to get a good feel for how it works and is a great learning tool.  I started with Zorin and ended up using Linux Mint.  I have 2 solid state drives in my shack computer one with Mint and the other with Win10.  Or id your drive is large enough you can double boot both on the same drive.  You will want to keep Win because there will be Windows apps that will not work using the Linux WINE app which allows you to run many Windows apps on Linux.  There will be a steep learning curve at first because Linux is much different than Windows including the terms used but you will find ample help for whatever distro you use online.

And it's all free!

Disabling Windows 10 Pro (and earlier) Automatic Updates

Lyn Norstad
 

Because this question continues to arise ...
 
Disabling Windows 10 (and earlier) Automatic Updates - Change the Setting of the Group Policy Editor
 
The Group Policy feature is not available in the Home edition. So, only when you run Windows 10 Professional, Enterprise, or Education, you can use the Group Policy Editor to change the settings to prevent Windows 10 from automatically updating. The group policy editor will notify you of new updates without automatically installing them. 
 
Press the Windows logo key + R then type gpedit.msc and click OK.

Go to "Computer Configuration" > "Administrative Templates" > "Windows Components" > "Windows Update".
Double-click "Configure Automatic Updates".
 
Select "Disabled" in Configured Automatic Updates on the left, and click Apply and "OK" to disable the Windows automatic update feature.

Note: If you need to update your Windows version later, you can repeat the steps above, then select Enabled to turn on this feature, so that you can continue to download the updates.
 
You'll also see other options that may better suit your needs.  And for convenience, you can also create a desktop shortcut "Group Policy" with just the entry " gpedit.msc "

How did you do it.

I am ready too dump WIN10.

Yesterday everything worked, today using JTDX, I can see 2 - 3 downloads and able to download and make 1 contact.

Would someone start a transition from WIN10 to LINUX chatline for us computer idiots?

Re: Desensing issue

Bob McGraw - K4TAX
 

As suggested, test with a known good quality 50 dummy load.  If the issue does not appear, then I would consider adding some ferrite chokes on the coax line at the K3 output.   If the issue appears with using the dummy load then as suggested, the relays in the amp may be at fault. 
 Also wouldn't hurt to add some on the DC power lead as well.   With an antenna that close there is a high likelihood of high RF levels at the operating position.

Re: Desensing issue

Stewart G3RXQ
 

Rob,
It might be a problem with the relay contacts in the SPE-1K amp. The original relays were not up to the job.
The symptoms describe the issue where the receive path is affected by poor relay contacts.
The original relays are ones manufactured in Italy. Changing them for Finder relays cures the problem .

I suggest that you join the groups.io SPE group and have a look at some the posts on the subject.

I use the SDR-Play here using the Console option.  I found that using the IF out on the K# caused signals to be reversed.  USB came out as LSB VS.

Some other peculiarities as well.  I think using this program anyway is better having it connected directly to the antenna in use via the BNC jacks on the back where one would insert a preamp.  At least this way signals and the freq display are all relative to what and where the K3 is and what it's seeing.

Sorry i'm having a mental block this morning and can't properly name the BNC jacks to use and looking behind the radio is not the easiest.  Happening more and more as time goes on.

There are many ways to set up N1MM SD, using I/Q data from some few transceiver types or a RX ANT loop or IF output feeding an external SDR. I use an Airspy HF+ in the RX ANT loop which works very well for me. YMMV.

Hi,
If I run a little extra power (ie 200W+) my receive signal drops.
I see this on the P3 as the noise floor drops and also in audio with AF drop.
Once the tx power is removed, a slow (meaning approx 2 sec) restoration of noise floor/audio is achieved.

Not having much space to play with (living in an apartment) my radio/amp are closely spaced and the antenna is approx 5m from me.
Antenna is new, coax is new and not considered as at fault as, with the previously installed antenna, I had the same issue.

I never run more than 500W.

I assume the closeness of the the antenna might be the issue but wonder whether there maybe something else I should be considering.


Using a K3 (8415) which is pretty much fully loaded (excl 2m module) and with no K3S mods. SPE-1K Amp and a Cobwebb antenna (3KW version)

Tnx in advance
