WGBH/WGBX/WBTS [and WFXZ]

[George Allen]

Apologies if it's already been covered here, but I finally figured 
out what's where with RF Ch. 32 [WGBX].  3 different station call 
letters on one RF channel - no wonder I'm confused.  1 HD, and 6 
subchannels with low bitrates for them.

Does anyone know how much WBTS/NBC-10 pays [ongoing?] WGBH for use of 
the RF-32 HD slot?

What's with the subchannel dimensions of 704/480? How does that 
become 16:9?  I'm missing something here.

The same info for RF-5, where both WGBH and WGBX HD [and WFXZ] live:

I suppose that's worth the $162 million WGBH got for moving to 
VHF-low.  Did that net them more than taking VHF-hi would have?

Add another $57 million for WGBY's move to VHF-high [RF-13].

Hopefully the 4.9x power increase [later this month maybe?] will be 
enough for my rabbit ears on a Terk HD-TVA.  I can see the d@mn tower 
from my living room in Swampscott, and can just barely get them with 
the ears fully extended [visually messy...].  All these decisions by 
WGBH to cash out spectrum were probably made before cord-cutting 
became much of a thing.  Yes, I can get low-def 2-1/44-1 on RF-32, 
but on a decent large-screen 4k TV the difference is obvious.
