I have a radio with tuning similar to your Jensen, a Kloss Tivoli table radio, modeled after the old KLH stuff of the 60’s. The potentiometer is devilishly difficult to get to to clean and it behaves the same way your radio does…haven’t had the patience yet to really tear into it to fix it properly…yet.
I actually have an old 1960’s KLH FM only tuner of the same style…works quite well with the old fashioned variable cap.
IMO, there really isn’t a really well built player with a good transport manufactured anymore, as there just isn’t that much of a demand.
The closest thing I can think of is from Tascam…but their quality has gone down considerably in the past decade or so…just like everyone else.
Another question: How old are the CDs that the volunteers are having trouble with? I do know that some commercial CDs manufactured in certain time frames have been subject to “bit-rot” due to manufacturing issues.
There are many variables involved here. Would it be worth it to crack open the old Denons to see if they need a cleaning? Only you guys can answer that question. In my case, I would give it a shot…but that might bring diminishing returns for you…good luck.March 31, 2019 at 6:47 pm in reply to: Audio chain conversions between digital and analog #41320
For our LPFM, all music files are uncompressed 44.1 KHz PCM, while all of our block programming that we download via FTP ranges from 192-256 kbps mp2 and mp3 all the way down to 64k mono mp3.
We just recently installed a Barix pair to stream our program audio from our studio in McMinnville to our transmitter out in the sticks (using stereo 384kbps mp3 stream) to replace the pair of old Dell Poweredge servers that we used to use to send programming at 192kbps mono .ogg streaming, using a local Icecast server. Not elegant, but it worked well enough for the time we needed it.
We would use uncompressed PCM to the transmitter, but the wireless connection at the transmitter end isn’t robust enough to support it and be reliable.
The audio from our automation is analog through our board, into our EAS, through some audio limiting and out to the Barix. At the transmitter audio flows in analog from the outputs of the Barix to our audio processor/stereo generator. I still need to find a good basic multi-band analog audio processor to pre-process the audio out at the transmitter site…but that is another story for another day.
Also, consumer 8 tracks run at 3.75 IPS, whereas most broadcast carts run at 7.5 IPS. The 8 track cartridge format was definitely a compromise for convenience sake, to be sure.
I had one of the plushier models of 8 track home decks in the past, a Superscope model with Dolby B and all of the bells and whistles, the frequency response of which competed well with the best cassette machines of the time.(wow and flutter not withstanding) Once cassettes got better, there was no reason for the 8 track to be around anymore.
Dan, with your permission, I can convert the .rm files of the KGW Columbus Day Storm audio, convert it to mp3 and host it on my site for streaming, if that would help.
The KWIP translator is now at 103.9, with fairly good coverage here in the Mid-Valley.
FWIW, 36.1 is still on in Salem, but it seems that no one seems to be maintaining it, many of their sat feeds are not working well at all. Frankly, it wouldn’t be a big loss to Christianity if the station were to go away, maybe a gain.
We did get the CAP first, but no over-the-air alert.(We monitor OPB radio and have a waiver to monitor KPXG instead of KWVT.) Both our EAS decoder and CAP/iPAWS machines are from Gorman-Redlich, the only failure with them was an incorrect timecode, otherwise they passed along the alert just fine. (One thing I don’t like about the G-R boxes, though, is sometimes they are finicky at the end of an alert and don’t switch back to studio audio. More than once, I have had to make a run to the studio to reset the EAS because we were inadvertently rebroadcasting OPB radio or the audio of one of Ion-TV’s crime shows! Also, some of their earlier units shipped with severly underengineered power supplies.)
I was expecting to receive the test over OPB-FM, but instead we got it through iPAWS. Worked surprisingly well…at our end, anyway…and it is only a test.
I just hope that it works successfully and that I can navigate the FCC’s new ETRS reporting system to their satisfaction. Listening for the test right now.
Yeah, it was a great, uplifting service. It was good to meet you and Phil again and chat even if it was only for a minute or two. Wish I could have stayed for the whole service, but my wife had a previous engagement in Newport she had to make. It would be great to hear more about that second online project that you mentioned.
I didn’t get to know him for very long, but found that he was a very gracious guy. My wife took his and his wife’s final formal photos together just a few months ago and we were able to chat with his widow this week as we delivered the framed portrait they will use for the service. While we were there, his wife showed us some other pictures of their many missionary trips to various parts of the world. He was really big on collecting eyeglasses for those in poor areas that he was visiting who couldn’t obtain them otherwise. My wife and I are planning on attending his memorial service as well, maybe we’ll see you there, Dan.
Every time I hear Trump speak, I can’t help but think of how he would be a great wrestling “manager” for a WWE character.March 16, 2016 at 6:02 pm in reply to: Radio Meltdown (CBS for Sale, IHEART upside down and Cumulus a penny stock) #18783
Like many, I have moved from terrestrial radio to on-demand content, such as podcasts. With a good data plan for mobile digital devices I can pretty much listen to what I want, when I want, and rarely tune in a radio anymore. For personalized streaming music, I have my own private Shoutcast server at my house, streaming what I desire to listen to, processed the way I like it.
Radio hasn’t even been any good for breaking news or emergency information anymore and that was radio’s strong point for so long, with that now lost, radio no longer has a strong point (with the exception of live sporting events) and it is just a matter of time before the big, expensive AM plants will have to be shut down.
Fantastic detailed explanation, Andy!
