It's all about the Software

Super station #1, 2, and 4 are offline for now...

#1 may come back in a while, but I will fire up everything in the AM.

This QRM appeared within the last few days on all my servers at the QTH, worst is on Super Station #2, which was my best system. :evil:
Starts at 1800kHz to about 2900kHz and again at 4050kHz to 4750kHz.
Heading out with the Youloop and AirspyHF+...

Had a bad case of Sciurus carolinensis or Tamiasciurus hudsonicus!
Grey squirrel or Red squirrel decided to chew on the insulation, and wires of the antenna about 4' from the 9:1 unun. Both ends were stripped about 2 so I wrapped the two back...

Something is wrong with Super Station #1, all signals are down by +20dB. Will have to walk out and check the antenna. We had horrendous winds for two days, and may be laying of ground or in pieces. Was too dark to investigate when I discovered it...

While fiddling with the RSP1A and it's needed AM BC filter, I noticed this mess on my screen. Was active this AM, then mid-day was off. Now this PM it's active again.
Peaks are at EVERY 6 kHz, which is a new one for me. The QRM drifts ever so...

I happened to be in the repeater shed and noticed a user on the new SDR-IP was down in the LW band. The AM BC filter was primarily for the RSP1A due to it's poor front end hearing/seeing AM signals all the way up into 40m. So... enjoy AM BC now on...

Super Station #1's antenna was getting progressively shorter and shorter with all the wind storms as of lately. I dropped it down and soldered the sections back together yesterday PM. Re shot the line up and over the Maple and Black Cherry trees in...

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.

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...
