From June of this year, I found this. So perhaps this is a newer STL:
** U S A. 26110 FM, KOVR TV, Stockton CA. Audible virtually daily now,
adverts including Walmart & program preview, mention of “CBS-13” 0559,
news 0600 on 10/6. On 11/6, “60 Minutes” 0115, Tony Awards coverage at
re-tune 0450, ID “In high definition, CBS-13 News” 0508, weather 0513.
Quite good on peaks (Craig Seager, Bathurst NSW, Icom R75, Discone,
ARDXC via WORLD OF RADIO 1621, DXLD)
KMK282 is its own symmetrical call. KOVR is really on RF channel 25
now with a megawatt ERP, but pretends still to be ``channel 13`` for
continuity and to avoid confusing viewers (Glenn Hauser, ibid.)
