Very sad news announced today by NRC Canada: "As of June 22, 2026, the shortwave radio broadcast of
the NRC's official time signal (CHU) will no longer be available." This follows Environment Canada's ending its Weather
Radio service on VHF FM 162 MHz in March 2026. Now we are only have the American HF WWV/WWVH & VLF WWVB time signals
& NOAA's VHF FM 162 MHz Weather Radio service (if you live along the US/Canada border).

Continuing work on my
WWV Propagation page by dropping HamSCI's legacy Grape 1 DCR design + 1000 Hz audio + fldigi & converting over to my UberSDR
+ RX-888 MKII using IQ signal processing thanks to Nathan, M9PSY's, awesome UberSDR. You can use any time station (WWV,CHU, etc.)
to do some really serious ionospheric research! My RX-888 MK II is GPDSO frequency locked & AGC is turned off for making
measurements — two important musts! But Nathan provides three reference signals to correct your RX-888 SDR on the fly for those without
the addon GPS clock kit & Bodnar GPDSO.

May the Fourth be with you! " Added link to the new & amazing UberSDR. If you hate Linux, as I (still do, but...) this
Linux-based SDR platform (standalone or cyberspace shared) is something for you to check out! It's not your usual browser-based SDR
because you do some serious radio science with it. If you can never get enough TMI then UberSDR is for you!
Also added a link
to Amateur Radio Daily. Keep abreast of the lasted worldwide happenings & news in the Amateur Radio world. Can never get enough
radio news TMI, either!

When MFJ Enterprises, Inc. shutdown operations with the retirement of owner/operator Martin
F. Jue, it sent shock waves throughout the Amateur Radio world. But some good news! ITU Corporation has aquired the famous Cushcraft
& Hy-gain antennas & rotators product lines. The deal includes all the designs, tooling, specialized equipment & marketing
rights. ITU has purchased the old former National Guard armory building in Linton, Indiana & will relocate manufacturing from
Starksville, Mississippi to Linton. Via Amateur Radio Daily.

Am now using an RX-888 MKII SDR to extend my WWV propagation page to include 15 MHz. See Radio Magic. The beta version of SDRConsole added more control of the RX-888's internal features.
I also bought Turn Island Systems
GPSDO clock kit, which includes a much larger, internal thermal pad & copper foil-to-case contact. But even with the larger internal cooling pad, the RX-888 still runs hot & it runs really hot with the small, stock & totally inadequate thermal pad so I have my two RX-888s itting on a ventilated aluminum stand with a large, but fairly quiet, USB powered (150 mm dia.) cooling fan.
