"SmartSDR for windows has lost connection please reconnect".

@Lee

The connection is exactly what it means and somehow the connection is fractured between the radio and the client.

Here are all the places it can fail in order from Client to Radio:

• The client software
• Computer NIC card drivers
• Physical NIC card on the computer
• LAN Cable
• Network Switch
• (Wifi if involved) - this is the weakest link and the first place to look
• Another LAN cable
• NIC card on Radio
• Radio software

The quick test is the link.local test where you do the following:

• Turn off the PC
• Turn off the Radio
• Connnect a LAN between Radio and the PC
• Turn both on
• Connect to the radio and see if still fails.

If it fails, then the problem is the radio or the PC.

If it doesn't fail then the issue is with the actual network.

I hope that helps a bit.

@John KB4DU Personally, I think that all AV stuff is evil. :) I don't even have it installed.

Systems scans require that every file is opened, examined and closed and that takes a LOT of CPU and Disk time, especially if you have a Disk that might be older and partially failing (even SSD).

Generally, if you think of how AV works, you can easily see the impact it can have even during the day (non scheduled scan). You want to open a file for editing. The AV 'spy driver' grabs it first and checks to make sure it is ok and then lets you open it (in fact, it is opened twice and that takes CPU time and power).

It is like this. You get a letter in the mail. Before you can read it, your Mom has to open it first and make sure it is safe. Then reseal it and hand it to you. LOL

The same is true for Firewalls that do deep packet inspection on your network communications. As they say, there is no free lunch.
