Best MWDX antenna?
~SIGINT~:
No blocking in effect, it is your browser setting. Images are hosted over http and the HFU is over https. This is called "mixed mode". There will be a setting somewhere in the browser to allow "mixed mode" browsing. I am willing to bet that you are using a Chrome based browser. Google, the self proclaimed "Internet police", at some point elected to disallow mixed mode browsing therefore by default, all Chrome based browsers have that function disabled.
It's a scam if you ask me. There is no need for https (encrypted traffic between the server and browser) unless processing / accessing sensitive data such as on-line banking or on-line shopping yet Google has forced everyone to adopt https so that they can get that pretty little "green shield" next to the URL bar that gives people that false fuzzy safe feeling that the content they are viewing is "safe". That couldn't be any further than the truth. But hey, certificate authority companies love it. They are raking in the cash by issuing people / sites certificates. For me, my hosting provider wants $100s of dollars to install a certificate. They won't even allow me as the site owners to install my own like Let's Encrypt . BS that is. Some day I have to find another provider.
RobRich:
Makes sense. I did not look closely at the URLs, as like you noted, most larger sites use SSL these days.
I have added your domain to my own local treat as secure list.

BTW, I am using Chrome Canary on this tablet at the moment, but I tend to use my own optimized dev releases of Chromium on Linux, plus I do cross builds for Windows. I apply higher SIMD baselines, opt level tweaks, various additional LLVM passes, PolIy loop optimizations, etc. I have been building Chromium for years, even well before my GitHub repo releases.

As I suspected, sensitivity is way down on the Kenwood R-2000 on a few HF bands. Suspect a failing cap or few, plus maybe the front-end amp and/or follower.
Tested against my R-600, which I rarely use, so naturally it is now drifting a little too much for my liking. Warm up helps, but that is annoying. Probably needs recapped as well, though I probably will check the usual R-600 suspect of cracked solder joints first.
So, want to figure out how to fit a Yaesu FRG-7 on a nightstand? lol Might have to toss a portable on there for awhile.

LOL, that is why I have the ICOM IC-R75 on the nightstand. The clock / timer function in that receiver is perfect for me. I have it set to 1 hour and the radio turns off automatically.
I see you have been busy with Chromium_Clang. I personally despise Chrome and most derivatives. The only version I occasionally touch when I have issues with my old locked down version of Firefox ESR is a portable version of Iron Browser. The key being "portable", no traces of Chrome junk left behind.
Now, back to scanning the house for sources of EMI / RFI. I found an unused telephone jack at the service entrance yesterday that has a buzz to it so it has my curiosity peaked. I am using an ultrasonic probe to look for leakage.

Actually, one of the best MW antennas that I remember making was to shunt-feed the 50ft tower that I had at the time. In the middle of the day, the NYC Big-3, (AM660, 770, and 880.), all came in at S9 from 300 miles away. Extremely low noise, being a couple hundred feet from the nearest powerlines. Originally, I did that to get on 160M, 75M, and 40M. On TX, a manual MFJ-941D tuner tuned all that in, but my GND losses were bad for transmit. However, on RX´ing, it was quite good. https://www.qsl.net/w9rb/webdoc9.htm

My 148' LoG was a decent MW antenna. Still the isual nighttime issues with an omnidirectional on MW, though phasing against one of verticals could help.
Tossed a Tecsun PL-330 on the nighstand last night. Reception works okay for the particular purpose, and I used a portables on a nighstand with a grasswire antenna for quite awhile years ago. Just annoying to deal with small buttons.
Just noticed my -20dB variable attenuator was fully engaged, thus some of the low signal reports in my shortwave loggings this morning. o.0 Oh well.
