[Skimmertalk] Skimmer and Live Audio

[Stan Stockton]

David,

Yes, QSB, changes in noise, etc. will have an effect for sure.

Speaking of storms, last night we had one.  I went to the station this 
morning and found that the USB ports on the computer do not work and the 
SDR-IQ will not come on.  Tried plugging it in another computer in my 
office with a working USB port and no success either.  Trying to get 
attention of RF Space to see what to do next.  If anyone has any 
thoughts I would appreciate hearing them.

Until this happened, what I was going to do was run a test on a band 
with no noise and have a line of sight signal with no QSB and run it 
about 25 times to see if I got an accurate reading of what the dB 
difference should be between various levels of power. If that test would 
prove that the thing is dead on, then it would be interesting to use 
this for some comparisons of antennas and stations.

While I was there I put the IC-765 on 14050.  You can hear the audio 
right now by going to

http://71.29.254.161:88/broadwave.asx?src=1&kbps=128

I left the filter in the wide position and the antenna is a 1000 foot 
beverage NE.  The S meter can be viewed at www.k5go.com Click on live 
camera and then JAVA or ActiveX.  There is a delay of 10-20 seconds.

Stan, K5GO
