This recording demonstrates electromagnetic interference #EMI #RFI caused by a newly installed Ruud Model RA-16 #HVAC air conditioning unit as received on my Kiwi SDR tuned to 21 MHz. This radio interference degrades my reception over 18 through 36 MHz. youtube.com/watch?v=PPfQ2e…

Be careful with your postings to online discussion groups. My posts on the Tuna Tin "S" #HamRadio #QRP transmitter project earned this mention in the "Up Front" section on page 22 of the December 2022 QST magazine. Thanks to James KN6QNJ for catching this!

My new Ruud HVAC's RFI is finally resolved with clip-on ferrites and a brute force line filter, with no help despite multiple calls for assistance to the installer and manufacturer. The original 16 dB increase in RF noise is now down to 1 dB or less. photos.app.goo.gl/Fdmf7LbawSYBCi…

Proof of concept... A vintage analog TV UHF modulator paired with an $11 Amazon RF amplifier module yield a low power analog UHF television station. FCC rules do not permit unlicensed low power transmitters on commercial television frequencies in the U.S. photos.app.goo.gl/eyQo7AbmUmboSy…
