Opera reaches an all
time low !
After making a guess at the carrier
level of 500 mW and not seeing any
spots for a while ,
may be the level was too low ,
Then, in came a Spot from Mike G3XDV
at - 31 dB , as non of the metering
was actually registering the Rf feed ,
checked the carrier level with the R&S ,
to find it was actually ~ 200 mW with the
test tone on !
So not 1 mW ERP , but
more like 400 uW !
And second spot at -33 dB
,
Not sure if its congratulations
to Mike for the low noise Rx , Mr JR
for the DSP or the 40ft top and
end loaded inv L in my 40x20 ft back garden ,
or the coca cola company for providing
the coil formers : ) [zero]
