[Hi-zreceivingarraydiscussions] Hi-Z 8 160m

Following up. . .FWIW. . .I have noticed that the array is noisier than 
normal.  Over a period of a few days I notice It is not hearing moderately 
low level signals that the TX array is hearing.        73. . . Dave, W0FLS

Hello Lee and company. . .

Over the past couple of weeks or so I’ve noticed some spurious signals in my 
Hi-Z 8 circle 160m array.  I’ve always had BC spurs on 1820, 1830, 1840, 
etc. but these are low level signals, just a few db above the noise floor. 
They seem to be random in frequency spacing.  Some are 1 KHz apart, some 
more, some less.  They are not clear, stable signals. . .rather, they are 
warbly and “fuzzy” (something like AU) and seem a little broad.  There are 
lots of them as I tune up down 20 or 30 KHz in the 1810 – 1835 KHz part of 
the band.  The array seems to have normal performance, reasonably good 
directivity, F/B, etc.  The signal levels do not change with direction of 
the array which leads me to believe it is something internal to the array. 
The weather here is very cold right now.  When it decides to warm up I will 
go out and re-seat all the various connections including the F connectors, 
connections from the preamps to the elements, element connections to ground 
rod, etc.  I do have the 75 to 50 ohm box in line as I feed the array from 
the shack with RG58.  I do not have a preamp in line.  Any ideas what might 
be going on?

73. . . Dave, W0FLS
