*** At least half the time mixing products such as these result from
sources separate from both the receiver and the transmitters. Where
does this spur peak ? Toward the 730 transmitter ? Or somewhere else.
If the latter it's almost certainly an external and separate radiation
source/ And either snow cover, saturated ground or frozen ground can be
the trigger.
