Here's an excerpt from R-I post saying which stations are threatened:
The only major L.A. FM stations who are not threatened are KYSR and KROQ, who broadcast from different mountain ridges....The following FMs are there (on Mount Wilson), though the stations with asterisks have
backup facilities at other sites:
[90.7 KPFK], 89.3 KPCC, 91.5 KUSC, 92.3 KHHT, 93.1 KCBS-FM*, 93.9 KXOS*, 94.7 KTWV*,
95.5 KLOS, 97.1 KAMP*, 99.5 KKLA, 100.3 KSWD, 101.1 KRTH*, 101.9 KSCA,
102.7 KIIS, 103.5 KOST, 104.3 KBIG, 105.1 KKGO, 105.9 KPWR*, 107.5 KLVE
The following TVs are there or on adjacent Mount Harvard, and I know of
no backups:
2 KCBS, 4 KNBC, 5 KTLA, 6 KSFV-LP, 7 KABC, 9 KCAL, 11 KTTV, 13 KCOP, 18
KSCI, 22 KWHY, 28 KCET, 34 KMEX, 40 KTBN, 44 KXLA, 46 KFTR, 50 KOCE, 52
KVEA, 54 KAZA, 56 KDOC, 58 KLCS, 62 KRCA
Millions of dollars worth of equipment could literally go up in flames... Wow.
Never mind the observatory...
That's a lot of dead air for a market that size, should the worst happen.
