I was just studying the likelihood of me being able to pick up KVOS-DT on channel 35 when it comes on full power from a site on Orcas Island later this year. KBCB-DT has its transmitter mast about 300 feet from the one for KVOS-DT and from my location in a Port Moody high-rise cannot pick up KBCB-DT, but can just about get a watchable analogue signal with a set-top antenna. A better, more directional antenna may work, but I have Coquitlam Ridge in the line of site.
Enter these co-ordinates into Google Earth and zoom in. 48°40'49.4" N, 122°50'26.4" W The transmitter buildings are visible and shadows of the present masts are cast in a north-north-west direction across some of the buildings.
From FCC documents, looking at the antenna height, radiation pattern and transmitter power between the two stations, KVOS-DT antenna is to be over 40 metres higher above mean sea level and will transmit with almost 4 times the ERP compared to KBCB-DT. The antenna patterns on both will put around 75% of the ERP in our direction. Four times the transmitter power will result in double the signal strength and might make a difference to some who are marginal like myself.
With reference to other Bellingham stations, there seem to be a few channels up for grabs. See here: http://www.recnet.com/cdbs/fmq.php?nprm=611033
In regards to K38JH Bellingham translator - this appears to be an application for an analogue NTSC transmitter, which makes no sense. The reason I state this is because the transmitter has a frequency offset. See here: http://www.recnet.com/cdbs/fmq.php?facid=128176
Click on the View Map link from the page and the analogue signal strength contours are shown. Analogue TV transmitters have frequency offsets such that if weather conditions produce co-channel interference from a distant transmitter, the interference pattern on the screen between the two vision carriers will be almost horizontal lines as opposed to a zero beat pattern which is extremely annoying. Almost any low level interference can produce an effect on analogue signal, but digital is not so affected because of the capture effect.
Another interesting Bellingham station is K54IQ. See link: http://www.recnet.com/cdbs/fmq.php?facid=130161
The primary station owner is shown as in Sherbrooke, Quebec which is strange for a US station. However, this application has been rescinded. I suspect that companies are just trying to acquire the Bellingham channel allocations for later use.
