[WriteLog] Question for Wayne re: DigiRite logs

[Ken K6MR]

Since my PG&E noise is still grinding away my mind wandered back to the WW Digi Test.  There was a suggestion (sorry, forgot who) that perhaps the problem of people not hearing/decoding stations could be clock related.

So I ran stats on all the DT times recorded.  I don’t really know what they should be, but they don’t look way out of whack.

For radio 1:  sample size 202247, mean 0.318, std dev 0.316.  Radio 2:  sample size 121571, mean 0.288, std dev 0.409

I would have thought that the mean would be closer to zero given the large number of samples.  N6ZFO where are you when I need you?


Just scanning through file I see something I don’t understand.  When transmitting, I usually see:

14:54:29 TX: WT8V NV6D CN80
14:54:34 145430  34  0.1 1829 +  WT8V NV6D CN80
14:54:34 145430  35  0.1 1829 +  WT8V NV6D CN80
14:54:35 145430  36  0.1 1829 +  WT8V NV6D CN80
14:54:35 145430  36  0.1 1829 +  WT8V NV6D CN80
14:54:36 145430  39  0.1 1829 +  WT8V NV6D CN80
14:54:36 145430  39  0.1 1829 +  WT8V NV6D CN80

Which I assume means my DT is 0.1 (100 ms?).  This is reasonably consistent for most of my TX lines.

For a few I see:

15:06:37 TX: CQ TEST NV6D CN80
15:06:41 150638  35 -0.4 1828 +  CQ TEST NV6D CN80
15:06:41 150638  35 -0.4 1829 +  CQ TEST NV6D CN80
15:06:42 150638  36 -0.4 1829 +  CQ TEST NV6D CN80
15:06:42 150638  36 -0.4 1829 +  CQ TEST NV6D CN80
15:06:43 150638  38 -0.4 1829 +  CQ TEST NV6D CN80
15:06:43 150638  36 -0.4 1829 +  CQ TEST NV6D CN80
15:06:44 150638  35 -0.4 1829 +  CQ TEST NV6D CN80
15:06:44 150638  35 -0.4 1829 +  CQ TEST NV6D CN80

And others are:

15:07:07 TX: CQ TEST NV6D CN80
15:07:11 150707  34  0.6 1829 +  CQ TEST NV6D CN80
15:07:11 150707  34  0.6 1829 +  CQ TEST NV6D CN80
15:07:12 150707  35  0.6 1829 +  CQ TEST NV6D CN80
15:07:12 150707  36  0.6 1829 +  CQ TEST NV6D CN80
15:07:13 150707  39  0.6 1829 +  CQ TEST NV6D CN80
15:07:13 150707  41  0.6 1829 +  CQ TEST NV6D CN80
15:07:14 150707  41  0.6 1829 +  CQ TEST NV6D CN80
15:07:14 150707  41  0.6 1829 +  CQ TEST NV6D CN80


So from one to the other is 1000 ms?  That seems way too big.  But what do I know.  Maybe it’s normal.

So does all this data mean anything?

Scratching  my head.
