At about 4 am we lost power on V1 and remotely found the cabinet would not become ‘ready’. On-site it was quickly apparent that tube bias was not satisfied and looking over the schematics again I decided to quickly isolate the tube to know where I should start looking. As soon as I pulled the…
Quite suddenly and without warning on February 27th, the V2 cabinet for our KBCW was constantly crowbarring (a safety function on high-voltage/high-power transmitters to prevent a tube short or other high beam current events from destroying the Inductive Output Tube) and would not hold high voltage for any amount of time putting our transmitter at…
While checking the Mobile DTV pavilion at the NAB convention in Las Vegas today I came across several mobile and portable devices showing off how well they can decode and display the new mobile DTV signals being broadcast. All save one…
I was recently talking with a sales rep I deal with and we got on the topic of the aging TV engineering workforce. He told me a rather depressing story about a recent SBE chapter meeting in his area where one of the old timers started poking fun at a couple younger members who were…
Regardless of what some liberal arts students or free-love hippies may tell you, you don’t get something for nothing. Or, better yet, as the redoubtable Robert Heinlein coined, “TANSTAAFL” (There ain’t no such thing as a free lunch). This simple truth frames the cold, hard realities about to face broadcasters after the current mobile DTV…
Not too long ago I had some time to review the capabilities of an Insignia CECB (coupon eligible converter box) and found that it was quite capable for its intended purpose. However, it lacked a few features and I discovered a matrix that showed one converter box with the most features of any CECB and…
This year’s NAB had a bit more energy among television broadcasters than the NAB show last year and almost all of it was around the mobile DTV plans and testing currently going on. Despite the interest in mobile DTV and the NAB claiming ~105,000 registered attendees, the North and Central halls were only mildly busy.…
No “film at 11” drama here; yes, it works and it works surprisingly well for a $60 piece of electronics ($20 after the $40 coupon is applied). For those that don’t know, this Insignia brand NS-DXA1 DTV converter box is one of a few available devices which are part of the US government’s effort to…
To be succinct, I simply don’t (and won’t) buy as much as I did before. For the past few years I didn’t think too hard about buying the week’s more popular DVD release of the latest blockbuster (or near blockbuster). This is why my DVD collection sprang to over 400 titles! I didn’t always buy…
Not many people get inside Sutro Tower, so I consider myself pretty fortunate. My current employer doesn’t have transmit facilities or other interests at Sutro, so I was escorted through the gate and into the facility by a contract engineer, John Buckham, that our SF station has who also maintains a radio station there for…
