It's all about the Software

I was tired of the old $20 HP Windows 7 netbook disconnecting from the LAN intermittently, usually while I was away from town. Moved it over to my daughters old W10 laptop that also hosts two Icom remote bases. When either of the two Icom's are...

Just a heads up...
My servers may be offline intermittently today due to power interruptions. Horrendous winds and rain are taking trees down onto powerlines throughout the area.
Just had a 10 second outage and new IP address given. My free DYDNS...

All servers at my QTH are down, no Internet/phone service.
My PCARC site is up though, same provider, but 10 miles away.

Widespread power outage in our area (not weather related). On the 20KW diesel genny for now, but expect another interruption when switching over to commercial power possibly.

Any users of my system notice when this QRM started?
VERY broad banded, and effects all HF bands. Noticeable on ALL SDR's here at the QTH! :x
I have a hunch it may be a powerline insulator arcing due to the sound and width of QRM.

See the examples...

For some reason my Free Dynamic DNS still has not updated. IP changed at about 1700z, but ISP's still haven't gotten the update.
I forced an update few hours ago.
KA1GJU@W1WQM is currently working due to being on a different IP and physical location...

Did some antenna improvements on Super Station #3 since it wasn't getting much use for reasons unknown to me. It was a 51' vertical, but now it's a 150' EFW as an inverted L, with about 65' vertical and 85' horizontal. The noise floor is still ~2...

While attempting to search for the source of 17M QRM I had to build new definitions of servers. I quickly learned it was a lesson in futility and total waste of time. :x

While looking primarily at servers located on the other side of the 'pond', I...

Enjoy the SDR's whilst the neighborhood is powered down!
Currently on my 20KW Diesel Genny for time being, all servers up.

May have power outages tonight, so my local servers may be down (Superstations1-4) while I power up the diesel generator and put everything back online. May have lots of static crashes due to lightning currently offshore as well, so 160m will be...

Possible update in last 48 hours? Super Station #4 was getting the 10 second time out warning. Apparently W10 decided to change the status of the port it was listening on and blocked it via Windows Firewall. Re-enabled and refreshed, all is well in...

I noticed a slow degradation in #1's RXR's... needed more and more visual gain and pre-amp.
Found that one of the dozen Sciurus carolinensis (Grey Squirrel) had chewed on the insulation of the antenna wire, exposing the wire to the weather. The flat...

While trying to connect locally (LAN) receiving a read failure message.

The log looks like:

We have a line of severe storms passing through, will attempt to get them back on line this evening, or tomorrow AM at the latest.
PCARC is online as well as Super Stations #1 and #3. I'd rather spare the equipment vs having to replace all the SDR's...

I have just setup my server for public access. It is using SDRPlay / Loop antenna.

It took me a few to realized why it was not connecting to the outside world. I had thought the Firewall and Router was properly configured initially but it was not....

For those that use my WD8ED SDR-Radio Server, you may have noticed it was down a day or two. The power here recently took a serious brown down after a lightning strike nearby. It took out the video display and power supply of the iMac 24 I was using...

Severe wind storm here in New England, power out 1530z. Currently on 20KW diesel generator with all servers powered up.

I even took some screen shots while the neighborhood was powered down to compare when it returns! No more electric fence noise...

Today I tried to add VHF/UHF capabilities to Super Station #4, but the Stridesburg HF Multicoupler that feeds all four SDR's from one antenna feedline doesn't pass VHF/UHF signals without a +28dB loss. The plan was to place a diplexer in front of...

Can someone report if my server is working alright?
212.187.10.14 login/pass = free/free

I can connect to my own server but get kicked after say 30sec with a message: no activity and console is not realy starting.
It looks like it starts but...

I spent yesterday attacking performance issues with the central On-Air server which runs on a small NUC here.

Performance issues found, fixed.
Increased socket timeouts.
All now much better.

Line of severe winds and rain killed power to PCARC clubhouse. Once returned, I will restart the Server there and look antennas over.

Climbed twice today in the high winds (but warm 23c/73f temps) to fix the 160M antenna up at 90'. I replaced the center insulator and added a few inches of antenna wire to accommodate the stretch of the antenna rope used to carry the weight of the...

Apparently I had the wrong antenna for the last several months! Now on the proper one as published (51' EFW in a vertical configuration with a 9:1 and good ground.)
I have numerous coax's entering the room where the server is located, all leading to...

While overhead NYC at 37,000', I could see a line of weather approaching the KA1GJU QTH both visually and with the onboard radar. The race was on!
I had my wife (N1YGF) pull the power and internet on the servers attached to the two Rohn25 lightning...

Had to reset both the Fiber Optic to Ethernet converter and the router after a nasty thunderstorm event a week back. Thanks to the Covid thing, no access unless escorted into the building.
Now appears to be functioning as it should.
