KEMO is not as strong today. My humidity is 61%. KRCB is fine.

KEMO-SD 50.2 appears to be very starved of bits. No audio either. 50.1 is fine.

I have seen this before, time to get a capture and run TSReader!

There have been huge swings in signal strengths here the last few days again. There have been periods of especially good conditions to Mt. Sutro. The previously troublesome KBCW was SNR 31 dB this afternoon and KPIX was SNR 28 dB. KGO was SNR 31 dB for several hours. The really good conditions were to Salinas again. I've attached a composite spectrum analyzer image showing KSBW towering above all the other VHF stations. Even KCBA was equal to or better than Walnut Grove. The red line is the minimum signal strength of the pilot carrier necessary for the station to decode if the rest of the signal is flat.

A couple hours later KCBA was falling off the cliff.

KFTY was booming at SNR 28 dB.

KEMO TSReader output

Hi,

I got a full stream capture of KEMO.

KEMO-SD 50.2 now looks much better than the "I Love Lucy" or other show staring Lucille Ball that was on 50.2 earlier.





I wondered if Lucy was botched when created from the original tape.

Is 1.82 Mbps too low?

Salinas LPTV is a mess.... or at least most of it is.

During some really good conditions this morning I surveyed the stations down there.

KOTR analog 2 - No longer on the air. No trace of a video carrier under superb conditions.
KMBY-LD 19 - Link problems, picture pixelates all the time.
KLFB-LD 22 - Off the air most of the time and has other issues when it is on the air.
K29AB analog 29 - Link issues, not always repeating KICU. Sometimes has just a ID slide or shows "No signal."
KDJT analog 33 - Has cross hatching interference. (This could be coming from KSDI analog 33 in Fresno although not a trace of KSDI-LD on 44 is detectable here.)
K38JP-LD 38 - Link issues. Pixelates when my TV says 0 errors.
KMMD-LD 39 - Has two dashed lines on the picture. See attachment. What is going on there?

There are a few more LPTV stations down there but I can't receive them.

Don't the owners of these stations ever look at them?

The one exception is KMUV analog 23 a Telemundo station. They now ID like a normal station and have partnered with KION to air a local newscast. I expect they will transition to digital on RF 21 eventually.
