Failure to do Maintenance=Failure to have Tower

This is a tower behind one of our FM transmitter sites.  In the past, it has housed paging and two-way services.  It has always been sort of a slum, in my opinion.  Several times, malfunctioning or improperly installed 900 MHz paging radios from this site have caused interference with our 950 MHz STL receivers.  In recent years, all those things have gone away however, to be replaced by a Wireless Internet Service Provider (WISP).  Even with this change, the site is mostly overgrown and uncared for.

Yesterday, I noticed the tower was not as tall as it used to be, so I walked down the hill and saw this:

It appears this happened a few weeks ago. View from the other side:

Looks like the bolts that held one the flanges together failed, the tower was pushed over by a strong NE wind causing the other two legs to fail.  Truth be told, the tower had been in rough shape since the mid 90’s.  I am surprised that it stayed up this long.

Carnage

WISP sector antennas. I don’t know if they owned the tower or were tenants. Either way, this is going to cost a few rubles to repair.

Looks like the shelter took a little bit of damage too. To be honest with you, I hope that this is it for this site. I would be nice if they take down the stump, scrap the lot of it and move somewhere else.

Upgrading the firmware

The original V series Nautel transmitters have required a couple of firmware upgrades in some cases.

Upgrading the power module firmware, WDVT, Rutland, VT

Upgrading the PA module firmware on Nautel V-5D transmitter, WDVT, Rutland, VT

The first was for the controller to add a little bit of bias to the PAs during analog operation.  The second one I have had to do is to the PA modules themselves which was to keep the power supplies from shutting off during re-transfer from Generator power to commercial power.

I have done several of these and once you get the hang of it, it only takes a few minutes to complete.  Still, I remember when transmitters didn’t have firmware.  The low voltage control circuits were either 120 or 240 VAC with big relays and contactors that loudly confirmed their closure before any meters began to move.

Regarding Nautel transmitters in general; the newer models are not same rugged, reliable designs that were common in the past.  We have AM ND series transmitters that have been on the air for 20 years without a single failure.  The models rolling out of the factory these days often have switching power supplies fail without reason or warning and RF pallets that are fragile things.  Ah well, I suppose all things are cyclical.

Sex Pistols backed by KGB

If this is true; Sex Pistols, The Clash and The Ramones were Financed by the USSR, then it was their best move ever.  According to the article:

The USSR government at the time spent “hundreds of millions of rubles” on this covert operation destined to create utter chaos… We even infiltrated mainstream radios to promote their music and reach millions of people everyday…

As far as I am concerned; The Sex Pistols, meh.  However, The Clash was pretty good and when I was living in California in the mid 1980’s, The Ramones were hugely popular with the surfer crowd and pretty much everyone else.

So, without further adieu and with special thanks to Комите́т госуда́рственной безопа́сности (КГБ):

There you have it; an English punk rock band, financed by a Soviet security apparatus signing (sort of) about an American car. Next thing you’ll tell me is that Billy Joel is a CIA front.
