In a literary piece I am working on; I intend on fabricating a fictional television station that consists of elements of WXYZ-TV when it was owned and operated by ABC, WJBK-TV when it was owned by Storer Broadcasting and was a CBS affiliate, WJW-TV/WJKW-TV when it was owned by Storer Broadcasting and was a CBS affiliate, CFCF-TV when it was owned by Canadian Marconi/English Electric up until it was owned by the Pouliots, and WKBW-TV. In other words; this fictional television station would be all these real television stations put together.
Regarding the fictional AM/Mediumwave station; it would have a history similar to WWJ-AM, CFCF-AM/CIQC-AM/CINW-AM, CFRB-AM, and WNBC-AM. The fictional AM station would have a newsradio format; as would be the case since 1923 (The fictional AM station would sign on in 1917 with an experimental call sign similar to WWJ-AM once having the call sign 8MK, and KCBS-AM once having the call signs FN, SJN, 6XF, and 6XE)
On-air staff that I would include in the news team of this fictional AM station would be WWJ-AM's Joe Donovan, KNX-AM's Jack Salvatore, and WBZ-AM's Flo Jonic
Regarding the FM station; it would have a history similar to WWJ-FM/WJOI-FM, WNBC-AM/WYNY-FM, CFRB-FM/CKFM-FM, CFCF-FM/CFQR-FM, and WGY-FM/WRVE-FM. However; regarding the format change from simulcasting it's AM sibling to having it's own seprate programming; it would be similar to when WKNR-FM became WNIC-FM, when WVEC-FM became WWDE-FM, when WWJ-FM became WJOI-FM, when CFRB-FM became CKFM-FM, when CFCF-FM became CFQR-FM, when WNBC-FM became WYNY-FM, and when WBZ-FM became WMJX-FM. Yes; this fictional FM station would have an MOR format that would be a mix of Mainstream AC, Jazz, and Easy Listening. And this fictional FM station would have it's format programmed the way Drake-Chenault would have programmed it. It would use the Johnny Mann jingles, and would have 20/20 news segments.
On-air staff that I would include for this fictional FM station would be Canadian Disc Jockey Marc "Mais Oui" Denis and Pat Sajak for the morning show, and New Zealander Disc Jockey Colin Magee for the afternoon drive.
Regarding the fictional Shortwave station; it would be modeled after CFCX-SW relaying CFCF-AM/CIQC-AM/CINW-AM's programming for longer distances, CFRX-SW relaying CFRB's programming for longer distances, WBOS-SW relaying WBZ-AM's programming for longer distances, Voice Of America Bethany, Ohio transmitter site originally relaying WLW-AM's programming for longer distances, Voice Of America Schnectady, New York transmitter site originally relaying WGY-AM's programming for longer distances, Voice Of America Dixon, California transmitter site originally relaying NBC West Coast and KPO-AM/KNBC-AM's programming for longer distances, Voice Of America Delano, California transmitter site orginally relaying CBS West Coast ad KCBS-AM's programming for longer distances, NBC Bound Brook, New Jersey transmitter site relaying WNBC-AM's programming for longer distances, and the CBS Wayne, New Jersey and Brentwood, New York transmitter sites relaying WCBS-AM's programming for longer distances
Regarding the transmitters; the fictional AM/Mediumwave station would operate on a GE 250 Kw mediumwave transmitter; and would operate on I-A Clear Channel status, the fictional FM station would operate on a GE BF-50-A, the fictional shortwave station would operate on a GE G-100-C, and the fictional television station would operate on a GE television transmitter of the 1960's that would be capable of transmitting color

When will this fictional piece be finished?

Whenever I get done with it.

What call letters are you going to give the stations?

NPVT-AM-FM-TV for the fictional AM/Mediumwave, FM, and Television stations, and NPVX-SW for the shortwave station (modeled after the call letters CFCX being assigned to the shortwave sibling of CFCF-AM/CIQC-AM/CINW-AM, the call letters CFRX being assigned to the shortwave sibling of CFRB-AM, and the call letters CKFX being assigned to the shortwave sibling of CKWX-AM)
