Yet another change in the audio streaming URL's

First, an apology to all on line listeners over the fact that the audio streams had been down for weeks before I discovered the problem. That is how busy I have been with other matters! Emails from my host that were sent a month in advance warning of a change in audio streaming servers somehow never made it to my Inbox. Here are the new URL's to bookmark in your favorite computer based player or Wifi radio:

Troubadour 1700:
http://69.80.74.84:7010

Liberty & Justice 1640:
http://69.80.74.84:7012

Personally, I hate URL changes in audio streams. They outdate your streaming bookmarks so fast, that even just a year later, half of them no longer work. But this was a business decision by my host and it is beyond my control. All audio links on the websites should be updated by the time you read this. Our pages on Tune In should also be working again shortly, as well as listening over the phone through Zeno Radio. Our phone numbers for listening remain the same:

Troubadour 1700:
1-786-265-1649

Liberty & Justice 1640:
1-786-265-1650

AM Stereo Experiments had mixed results

After an experimental period of several weeks operating in C-Quam AM Stereo, Troubadour 1700 has gone back to mono operation with the installation of a second new SSTran AMT-5000 transmitter. But in retrospect, I may have been too critical of the ASMAX-1 AM Stereo transmitter I had been using for the experiments. It did sound very good and provided excellent stereo separation and competitive signal range. I had to modify the ASMAX-1's audio input to give it the "SSTRan sound" that has been a trademark of Minimum Wage Media's AM signals. But after the installation of the second new AMT-5000, a few anomalies and artifacts that I had blamed on the ASMAX-1 were still there.

The trickiest part of our AM operation is the fact that we have two transmitting antennas only 12 feet apart in distance and only 60 kHz apart in operating frequency. A major adjustment or tuning on one often effects the efficiency, range, and behavior of the other. Plus, ground conductivity is never the same, especially as the seasons change. So to get both stations at absolute peak antenna tuning and at equal maximum signal output is a difficult challenge. But I am happy to report that we are pretty much there at this point and certainly better than through most of our history. So the current setup will remain as it is through next spring, minus the AM Stereo, unfortunately. During the winter months, I will need to concentrate on the goal of vastly expanding our network of transmitters throughout north central Massachusetts and the Nashoba Valley region with the creation of an Indiegogo fund raiser to help make it happen.
