 Been through that explanation so many times.....

 My given birth name is Curtis W. Flick, but very few even know that.
 Ask in any of the top 100 markets or so, somewhere in 49 states,
 there is someone that knows "Cowboy" so....

 Don't know.
 Carl T. Jones did the engineering for the diplex and array design.
 I did the "radio engineering" construction. ( install ATU's and such )
 And worked with almost the entire Carl T. Jones staff of consultants
 through the tune up(s) and proof(s) for both arrays. ( weird vacation
 schedules through that project )
 Magnum / P&R built the steel.

 That was the first job I/we used GPS to aid in a field proof, but used
 it entirely as a secondary reference.
 ( there were a number of firsts on that gig, like catching the ATU
 building on fire ( literally ) at tower #1 )
 (( the roofer did the station a favor, and put a metal drip edge all
 the way around, which constituted a shorted turn, and with some
 48 kw or so within 5 feet of that shorted turn.... ))

 No.
 Pretty conventional stuff.

 There is no reject power.

 Yep. All in the WIBG building.
 DX-50 upstairs for WNTP with the screened "phasor room" in the basement
 still as it was.

 New DX-10 and phasor for WFIL in the basement, next to the WNTP phasor.
 ( due to efficiency issues with WFIL and short towers, WFIL now runs 8 kw
 or so to obtain 5 kw worth of coverage )

 Don't know. Might have.

 Still there, next to the golf course / Country Club.

 Long gone now.

 Nothing I'd know about any of that.
