Mario finds a monophonic earphone with 6 foot cord

Many thanks to SWLing Post contributor, Mario Filippi (N2HUN), who writes:

Attached is a picture of a recent purchase of mine from eBay, a six foot long monophonic earphone for use with my Panasonic RF-2200.

Single mono earphones of that length are not easy to find. Most are too short for night stand use. And with the abundance of RFI emitting appliances in the home, a six-foot long earphone allows me to move my portable radio far away from things like laptops, cell phones and noisy power supplies.

73’s,

Mario N2HUN

Thank you for sharing this, Mario. I love how practical and affordable this is and the fact that the earpiece is identical (save cord length) to the original that would have accompanied the RF-2200. Click here to check out this item on eBay.

Some time ago with a friend of mine I created a very big archive of CW QSO recordings available for everybody who want to listen to CW traffic. The idea was born by the need to give to newcomer HAMS material to train on real CW traffic on the bands (with QSB, QRN, QRM, etc.).

So we started to record our ragchewing, ordering files with date/calls of participants/frequencies/keys used and WPM speed of QTC. At the beginning it was not a serious matter, but nowadays the archive counts thousands of records with local and international radio friends…hours and hours of “swinging morse code.” Some of these QSOs are made with ex professional RT involved on radio ham bands spending time talking about the past golden era and having QSO with OMs on the radio.

We released this large archive of recordings in a Google drive folder that can be shared. The archive is located at the following link : https://drive.google.com/drive/folders/1XaF3Mvwa6WvgOCzZjp0NwzgnYdNHsW2Q

Thank you for sharing this, Luigi! What a wonderful idea. I think I will approach you about adding a few of these to the Shortwave Radio Audio Archive as well as there are very few ham radio CW recordings.

How the Cassette Tape Helped Create the Internet (WNYC Studios)

In 1983, Simon Goodwin had a strange thought. Would it be possible to broadcast computer software over the radio? If so, could listeners record it off the air and onto a cassette tape? This experiment, and dozens of others in the early 80s, created a series of cassette fueled, analog internets. Our friend Simon Adler at Radiolab reports.

This is a segment from our November 26th, 2021 program, How Cassette Tapes Changed the World. [Read and listen to this piece at WNYC Studios…]
