Spectrographs of W1AW FMT Fall 2008 FMT

  Absolute RF frequencies to the left of zero are higher and frequencies to the right are lower. Just use a mirror and everything will look normal hi hi..... 

W1AW does appear to have started at their appointed time. WA6ZTY started his 80 meter run about a minute before W1AW stopped transmitting.

Fall 2008 WA6ZTY 80 Meter FMT run

Note: What appears to be a forth tone is actually WA6ZTY sending dots at the end of the run before returning to the carrier frequency.

Fall 2008 WA6ZTY 40 Meter FMT run 

Propagation was poor to WA6ZTY at the time, signals were too weak to be heard by ear.

 

 

WA6ZTY 80M Carrier detail

Note that the carrier shows to be .0067 Hz high on this click of the mouse Cursor at 20:58:32 central time. 

Less than +/- 75 millihertz of Doppler was noted during this 4 minute period. Remember a negative off-set from zero represents a positive increase in real RF frequency on these spectrographs.

WA6ZTY 80 Meter Low tone detail

The published low tone is 980.57 Hz. I'm showing very little Doppler on this click of the cursor 10 seconds past the top of the hour

 

 

 

WA6ZTY 80 Meter High tone detail

The published high tone frequency is 1500 Hz. I'm showing about .046Hz of Doppler on this click of the cursor at 4 seconds before the top of the hour (9pm cst)

Note: What appears to be a forth tone is actually WA6ZTY sending dots at the end of the run before he returned to the carrier frequency.
