I notice a lot of 1 kg weights on
Just as a side note.. I have looked at the propagation of DTV pilot carriers
(as part of an "over the horizon" VHF radio propagation experiment) and the
Doppler shifted carriers due to reflections from air craft were typically
detected separately along with the "over the horizon" pilot carrier
Well, I once had a nutty idea which was to detect earthquakes by looking
for the phase
variation of DTV station pilot carriers due to seismic waves propagating
around, thereby
changing the physical distance between transmitter and receiver in a cyclic
manner
until the 'quake calmed down. Doing
Well I have enjoyed time and frequency measurement for many years. I have no
equipment (nor do I expect to get any) that can tell the difference between the
current second and the proposed standard. And at one point I asked if there
was a limit on the smallest time interval that could be
