These are the first visits of this year to Table Mt and no obvious issues were found, other than continued deterioration of the tower and its associated hardware. The following actions were taken:

On the morning of June 4 I went up to Table Mt to install a UPS and automatic transfer switch (ATS) to help with power interruption issues. The weather was not bad (T=52 F), when I got there the view toward the ODOT tower looked like this: When I left, Read more…

After 4 weeks of observation, and with no further microwave radio restarts, it appears the situation has indeed stabilized. That does not mean that there are no further dropouts – there are occasional dropouts, and there have always been dropouts as nearly as I can tell, although they were not Read more…

On September 29, with Robert Hantzsche’s help, the second microwave radio was replaced (at Table Mt). From there, it appeared there was still an issue on the Studio side that was limiting. The most likely issue would be the cable, as that radio had been replaced, and when replacing it Read more…

In order to improve the signal reliability, it was decided to replace the vintage 2014 microwave radios in the STL system with next-generation units from 2021. Because the technology is not the same, the radio unit on the studio end needs to be replaced first – the studio end is Read more…

The signal interruptions that we have experienced starting in the first week of May 2021 are not from any audio components, or from the studio side of the network. They come from somewhere after the transmitter side microwave dish. Beyond that the current diagnosis is given below. A trip up Read more…

Dan Sullivan volunteered for us to have a look at the studio side microwave dish on Sunday March 7. He found that it had fallen onto the roof due to the pole that was mounted from below coming loose from its moorings – so much for wondering what the problem Read more…

On Thursday March 4, Don and I went to the transmitter site on Table Mountain to see if the problem occurring with our broadcast was on that end – which seemed likely at the time. Once we made it there on Don’s snowmobiles, we examined and re-aimed the microwave dish Read more…

If you hear drop outs or garbled sound output when listening on 89.5 or 94.1 FM, those sounds may result from a failure of the transmission of the signal from the studio at 1661 Hwy 99N to the transmitter on Table Mountain. This signal is transmitted via a microwave link Read more…
