[NLRS] 432 Radar source KNOWN!

[Bill K0AWU]

Hi Guys

  For a while I thought it was my imagination, NOPE it is real. I have been 
HEARing a LOT of HEAVY turboprop traffic since we got home from our 
Florida trip. On about 4 or 5 occasions I have made trips to the yard with 
binoculars to try to get a look at these "birds". Just a few moments ago while 
listening to STRONG 432 radar, I once again hear the deep rumble of 
turboprops. A quick trip to the backyard with the binoculars this time 
confirmed a theory.

  The radar we are hearing is airborne radar from 4 engine turboprop aircraft 
fly constant E-W patterns over northern Minnesota for an unknown distance 
in both directions. The AWAC type dish was VERY visible as well as a P-6 
type stinger extending the fuselage beyond the tail. This flight a few min ago 
was by far the lowest flight that I have observed.

  With the aircraft overhead the radar nulled out, only to return a few 
moments later as he passed the zenith. 

  I thought they had been moving down to 432 every once in a while, but now 
I think it was just a matter that they were getting closer and as a result 
LOUDer!

  I would guess we know why they are flying. Only time will tell how much 
longer it will be needed.
