Mar 3 Podcast #1089: Freeform Radio of the 70s and 80s and Why Audio Reviewers Can't Hear Obvious Flaws
This week we take a trip down memory lane and discuss Los Angeles free form radio from the 70s and 80s. We also discuss a technology that may make LCD TVs obsolete. And finally we talk about audio reviewers and whether it's worth listening to what they have to say. Plus we read your emails and the week’s news.

Freeform Radio from the 1970s and 80s
The other day I was wondering about a DJ that used to work at KLOS in Los Angele. Her name was Linda McGinnis. She had a beautiful voice and was an excellent DJ. So I wondered if she was still on the radio someplace. As it turned out she had passed away in 2003. If you lived in San Diego or the Bay area during the 70’s and 80’s I am sure you heard her.
However, in doing my search I found a couple of recordings that some had done and digitized off of an old cassette tape and posted on the Internet. It was an hour of Linda’s daily show from October of 1981 replete with commercials of the day. It was a glorious trip down memory lane!
This started my trip down the rabbit hole! I found many other recordings from the DJs of KLOS and KMET all making me sad for the days when radio had true artists spinning the tunes. Back then, at least on freeform rock stations, DJs would curate music for you and help you discover artists and bands you never knew you needed to hear. For the past few days, I have been listening to these recordings in my car with a huge smile on my face.
Some DJs like Jim Ladd (from both KLOS and KMET fame) have freeform shows on Sirius radio. Jim can be found on Deep Tracks channel 27. Otherwise if you had a favorite DJ from your youth I recommend that you search his or her name and see if there are recordings from back in the day. You will thank me for this.
Surprisingly, Apple Music Radio is old school with it's DJs. My tastes have broadened to include country music so I listen to Apple Music Country and find their DJs are very much like the DJs of the 70s and 80s. They create sets based on their mood, time of year, or what their listeners are requesting. The DJs are in the industry and based in Nashville so they have their fingers on the pulse of what is happening in the country music scene.
I have discovered a bunch of country artists before everyone else in my circles. It's kind of fun being ahead of the curve like I was in highschool! I am giving my daughters music suggestions and they are wondering how on earth this old man knows about new artists before they do!!
I haven’t listened to the other Apple Music stations but I assume the same thing happens there. Do you have a favorite station that’s old school? Let us know because it's probably available through an app.
I am going to play about a minute of Linda on the radio. It made me sad and happy at the same time. Also, John in Cornwall there is a baseball comment in there that I hope you enjoy!

Meta-display concept could retire LCD panels in big-screen TVs
The metasurface display technology could replace the LCD layer in flat-screen televisions, bringing thinner panels, higher resolution, fast response times and lower power consumption. Full article here…
-
The metasurfaces are 100-times thinner than liquid crystal cells, offer a tenfold greater resolution and could consume less energy.
-
metasurface cells would replace the liquid crystal layer and would not require the polarisers, which are responsible for half of wasted light intensity and energy use in LCD displays.
-
The new technology pixels are made of silicon, which offer a long life span in contrast with organic materials required OLED. Moreover, silicon is widely available and cheap to produce.
-
The metasurface array could effectively just replace the liquid crystal layer in today's displays, which means manufacturers won't need to invest in brand new production lines to make panels.
-
The next phase of research will be building a large-scale prototype and generating images, which is hoped to be achieved within the next five years. Once the prototype has successfully generated high-definition images it is expected the technology will be integrated into flat screens and available to the public within the next 10 years.
A Room Full of Audio Reviewers Can't Hear Obvious Flaws
A couple months ago, I went to a press event I decided not to write about. The reason I demurred is that I could hear crackling and hiss coming out of the speakers when nothing was playing. But it occurred to me that no one else noticed that the system—a six-figure rig with some well known high-end gear in it—had the noise floor of a transistor radio playing static.
This is not the first or last time I've been in a room with audio reviewers who seemed to have no clue. I can recall one demo where the tweeter was blown on one of the speakers, and another where the source material turned out to be 96 kbps MP3.
No wonder some of these folks avoid double-blind tests like the plague.
