DTV Construction Permits

Post by djb » Sat Nov 11, 2017 9:24 pm

According to the FCC site, many stations have permits for the allotment change. Interestingly, WNEM will move to WEYI's transmit frequency, and cut power in half, and switch to elliptical polarization. WEYI moves to RF18. CW46 moves to RF23 (which I'm thinking is why WNEM, directly across the street has to move from RF22), with a power reduction as well.

Here's a dirty table I compiled of the current licenses and CPs.

Code: Select all

      VIRT           RF              kW          AntHght            Polar-Direct/Non-Direct
L	5		22		1000		278.4		HPOL-D
CP	5		30		 585		307.6		EPOL-D

L	12		12		 30		293.4		HPOL-ND

L	14		26		 450		287		HPOL-D

L	19		15		 200		312.7		HPOL-ND

L	25		30		 193		335		HPOL-ND
CP	25		18		 98		394.6		EPOL-ND

L	28		28		 500		269		        HPOL-D

L	46		46		 70		312		        HPOL-D
CP	46		23		 43.9		312		        HPOL-D

L	49		48		 851		294		        HPOL-D
CP	49		35		 678		294		        EPOL-D

L	66		16		 25.1		357		        HPOL-ND	
CP	66		16		 245		371		        CPOL-D[

What doesn't make any sense at all to me, is in areas north of Lansing/Detroit/Grand Rapids, why frequencies have to be changed? Is it really that big of a deal that WEYI has to move and WNEM takes WEYI's former frequency? Honestly...why doesn't WEYI stay where it is?

If I would have to guess, it's due to RF46 having to switch frequencies. So, 46 switches to RF23 (why 23 was chosen, who knows?), but TV-5's RF22 is a stone throw's away from 46's RF23. So, TV-5 moves off RF22, over to RF30 (again, who knows?), which forces WEYI to RF18.

If my opinion, 46 should switch to RF18, and the rest could have been left alone.

It's like Northern Michigan with WTOM going from 35 to 16 and WPBN from 47 to 35...why isn't WPBN going to 16?

What's even more perplexing about this is that in Detroit, WTVS is moving to RF 20 when it's on the same tower as WWJ-TV, which is taking over RF 21 from WMYD, which in turn will move to RF 31. Not to mention before full-power analog broadcasts were shut down, many stations had their pre-transistion digital allotments (that they were assigned in 1997) right next door to their then-current analog allotments.

From what I seem to remember reading somewhere, the repack channel assignment process the FCC used was done mostly, if not entirely, through software automation programmed to use a certain set of criteria.

As for the reductions in power at WNEM and WEYI, I assumed that, according to their CPs, it's because their post-repack antennas are going to the top of their respective towers, where their old analog antennas were.
Isn't it nice how deregulation has brought us such oversized and dangerously overleveraged broadcast owners? (Yes, I'm looking at YOU, Sinclair, Nexstar, Cume-U-Less, and iFart!)
