Nice. It would appear that you are not the prick most people in other hemispheres would have us believe. Many many moons ago when cable TV was still analog, I put an A/B switch on the main line of my cable and used the B side to feed my distribution amp in which the output was connected to a set of rabbit ears and the A side to feed the cable box. That setup broadcast the whole VHF spectrum to any TV in the shop I would put a clip lead to. One day the cable guy comes in - they had been driving around "sniffing" for leakage, and my store was a real hotspot. He thought I had an open ground, but I told him I knew where the bad crimp was and threw the switch to A and the problem went away. The next day I went back to using the B side and a couple of months later they came in again, so they must have sniffed routinely , so I abandoned the plan. I should have tried broadcasting the output of the box alone - maybe they wouldn't have bothered me if it was a narrow spectrum. |

That is a well made Agile modulator with a decent VSB filter before the upconverter. My comment wasn't meant to imply that he wouldn't get a modulator, just in case something happened to it. Too much stuff is being lost or damaged in shipment these days. Fedex just lost a Sadelco FSM of mine. The love to leave my packages at similar addresses on other streets. Some of the old analog FSM have a crude but useful Spectrum analyzer mode built in. Peter might even want more than one modulator, on adjacent channels, to show how old TVs deal with Intermod and Co-channel interference. I finally have a HP 1.3 GHz counter to fill in the gaps in the programming chart for that model. I believe it goes down to the T channels, that were used for reverse feed but I can't access my outboard drives until I complete electrical repairs. An open neutral from the pole pig fried most of my equipment, and all of the surge suppressors on one phase. I currently have one working 20A single phase circuit and a lot of dead equipment after that phase went over 165 volts. As usual, the utility just rolled their eyes when I told them the neutral was open. They sent an automated call just before midnight, canceling the service call, since their so called 'smart meter' reported that I had power. They don't report an open neutral. I had to threaten to report them to the PUCO when I called back, before they actually sent out a truck. Once again, I got attitude, then the lead tech saw the bare neutral arcing where it had broke. That drop was installed in 1964. -- Never piss off an Engineer! They don't get mad. They don't get even. They go for over unity! ;-) |

That stunt could have wiped out communications for emergency vehicles on the VHF high band, the two meter ham band and airports. You could have indirectly caused people to die. We had people do that in Apartment buildings, near Cincinnati. We had to install monitors in all of our trucks to find them as soon as possible. If the FCC got involved, it could have lead to time in prison. Cable TV uses those frequencies on a shared basis, under the condition that leakage levels be maintained. On big problem was morons slipping 300 ohm flat antenna cable under a carpet, to move the TV to another location. It could be detected from blocks away. Our sniffer system was outdated, but the video carrier for MTV was on the right frequency so we could still use the receivers. -- Never piss off an Engineer! They don't get mad. They don't get even.

They told the seller that they had over a two week backlog, and to use anyone else. I wasn't given the choice. Fedex often delivers after 9PM, which doesn't help. UPS often gets here after dark, as well. -- Never piss off an Engineer! They don't get mad. They don't get even. They go for over unity! ;-) |

Instead of an incorrect delivery, you get a note in the mailbox saying "We tried to deliver but no-one answered the door. Please come and pick it up at our warehouse" (40 minutes drive away). I've watched couriers delivering such notices, rather than walk the ten steps to the front door and ring the doorbell. CH. |
| "pfjw@aol.com" <peterwieck33@gmail.com>: Sep 02 06:58AM -0700 Thank you all for the information and suggestions. I will be able to test the concept with our big Sony CRT type TV we brought back from Saudi as it has an on-board OTA tuner with NTSC/PAL/SECAM compatibility. So, I will report back when it arrives from Ranger, TX. And. after Kutztown, I will report on range. Thanks again! Peter Wieck Melrose Park, PA |
