On the subject of project management; often times, we need to keep track of the small details that can derail a project, blow the budget and upset schedules. A quick check list can help to identify things that might not have been planned for. I developed a checklist mentality in the military. There, we had checklists for everything. Simple day to day things like disposing of garbage over the side, or pumping the CHT (sewage) tank to complex evolutions like entering or leaving port all had a checklist. On the aforementioned CHT tank; the Coast Guard cutter I was on had a vacuum flush system to conserve water. Emptying the CHT tank involved a complex set of valve openings and closings to rout compressed air into the vacuum tank and literally blow the sewage overboard. Anyone can see the danger in such a design. Failure to follow the exact procedure resulted in raw sewage blowing out of the nearest toilets, which were unfortunately (or perhaps humorously) in the lower level officer’s staterooms.
But I digress.
I have made a series of outlines for different project types. These can be used as general guidelines for project planning and management. Of course, each project is different, but these are flexible enough that they can be adapted on a project by project basis.
What better time to take the gondola to K-1? None, none at all. We do work for the two radio stations that are on the peak of Mount Killington, near Rutland, Vermont. In the summer, usually we can drive up there in a four wheel drive truck. In the winter, the gondola is the way to go. On this day, there was a 48-56 inch base, light north winds and air temperature around 10° F (-12° C) .
This is not my video, I did not have enough memory on my SIM card to film a video and I didn’t bring my expensive camera. However, this is a good example of the ride:
Not a bad way to get to a transmitter site, all things considered.
The reason for the trip today; repair work on the Nautel VS2.5 transmitter. All three power supplies and the power supply summing board needed to be replaced.
We removed this old Harris BC5HA transmitter recently:
It was installed new in 1974, when the station moved to this site from another one a few miles up the road. It functioned as a main transmitter until the BE AM5E was installed in late 2001. The BE transmitter, other than a power supply issue, has been a solid, reliable unit. Truth be told, the last time the BC5HA ran was in 2006. After that, the unit refused to run, a bad modulation transformer was suspected. It was deemed not worth it to repair, thus, out the door it goes. We ended up giving it to a local contractor who scrapped the metal in lieu of payment for his labor. The only thing he could not take was the aforementioned modulation transformer, which is full of PCB’s. That will have to be hauled away by a licensed disposal company.
We may be getting a second hand Nautel transmitter from another station as a backup transmitter. If that comes to fruition, then a couple of racks can be added to the end of the Phasor/transmitter/transmitter row and the wiring for the remote control and STL can be simplified and neatened up.
That saying originates from Greek and Roman times, when Sirius, the Dog Star, aligned with the Sun during July and August and was though to bring extra heat to the earth. The Dog Days are evil times; seas boil, wine turns sour, dogs grow mad, and all other creatures become languid; causing to man, among other diseases, burning fevers, hysterics, and phrensies.
Bad news, indeed. Add to that; air conditioners fail, general managers become cranky, transmitters overheat causing damage to sensitive control circuits, which is even worse.
We shall be busy dealing with things like this:
Air conditioning condenser with low refrigerant. This unit either has a leak or was not charged properly. I would hazard the former.
Fan blade on condenser coil failed due to metal fatigue. I have seen this in more than one place.
These wall mount Bard AC units are pretty reliable, however, even they fail from time to time. The best course of action is to have a maintenance plan, a backup plan and the number of the best HVAC contractor that can be found.
