Sorry folks, I haven't been checking this board lately. I spoke to the Chief Engineer at WIFR yesterday to find out why the HD programming has not been available lately. As it turns out, they lost their CBS provided HD satellite...

WIFR is operating at 49.6kW which is the maximum allocated for it by the FCC. We are operating under a STA due to an antenna center of radiation which is slightly lower than our allocation (due to the antenna being side-mounted). This...

For those of you monitoring DTV status in Northern Illinois, WIFR-DT CBS in Rockford in now up for equipment testing. It may be on and off over the next couple of weeks but should generally be available. There is a little work to be...

Timmy, Just talked to Jeff from the transmitter site. WIBW-DT is now running at 95kW as of 8:05 PM. Good luck with your reception and let us know if you have any better luck now. Again, thanks for your feedback. It helps more...

Hi Guys, if all goes according to plan, the DTV should be up at 95kW tomorrow morning. Thanks for your support

Hi, while I'm not in Freeport I am in Rockford (NE side). I am able to get WREX-DT OTA using a small set-top antenna (Silver Sensor by Zenith/Antiference bought at Circuit City) and a Samsung SIR-T151 tuner. Furthermore, believe it or...

Hi guys, Here's where WIBW stands as of 3:30 today...we took the DTV off air so that we could run the main (analog) signal on the temporary line that was being used to feed the DTV. We have installed the channel combiner/splitter in...

Actually, to determine ERP in a given direction the formula is: MAX ERP * relative field squared. So if the relative field at a particular azimuth is .6 and the MAX ERP for the station is 1MW, the ERP that azimuth is: ...

Tim, I should have mentioned that WIBW is using a temporary transmission line at the moment. It is very lossy and consequently we are operating at only abour 25kW. We are waiting on a component that will allow us to use the correct...

Tim, We have found that intermittent reception as you described is most commonly as a result of multipath interference ('ghosting' in the analog world). Multipath is caused by the signal being received at the antenna by reflected...
