The reason we killed the FSN up there was that the tower owner decided that even though we only had one transmitter operating on one channel, they decided that we owed them 6X the original lease amount per month because we were re-broadcasting six stations on that one channel. They figured that every station on the 3.0 SFN owed them the full lease amount. So the SFN site for ch27 on Shaw is no more.
Huh. There's no FCC filing indicating that...

Trip,
By the time that happened I was no longer working for Peal as I was then a (very) part-time maintenance engineer for ABC15. Scripps had taken ownership and paid the vendors for all of the SFN loaner equipment (xmitter, antenna, line, microwave, etc.) well before the tower company changed the deal. Given the exceptional competency of the KNXV engineering dept, I'd look to the mothership for an answer to that.

For what its worth, I was told this long ago about shaw butte, 3 months later my signal levels dropped from -10dBm to around -33dBm which is around what most my majors are from south mountain show. So I do personally believe it was dropped but always mention such supposedly exists as I have never seen an official statement of such. Is there any way in "render" to get such specific tower data when there are multiple towers on the same frequency? I know in the past when there were issues at shaw butte, I could tune the signals if I went a bit south of thunderbird.

Every now and then I will see plp0 (that has "no" data) have a very high signal strength (around -20dBm, not as high as it was, but higher than I usually see from south mountain) but once plp1 is accessed I don't see that high level again even when tuning just plp0 unless tuned to a completely different frequency and even then it may be days before I see that higher level again. Now having my smartkom, levels are all essentially the same so it is tough seeing those numbers vary like they did.

My understanding from one person I heard from (someone other than bobchase) said that it was having the multiple .1 channels that "brought up the price" as it was thought each major "should" pay their share but that really doesn't make any sense to me as it is just data and shouldn't matter how many streams it serves (though some things before the tower are often licensed on a per station, possibly per stream basis to do the encoding).

I do hope I get an excuse to play with getting low vhf to work (however where I want to put such is a bit too narrow)
