Subject: [Flexradio] Flex 1500 on 10 GHz weak signal
got a chance to try out my new Flex 1500 on 10 GHz last Saturday.
the N.E.W.S. Group was running MDS (Minimum Discernable Signal)
testing on 10 GHz. (you can read more details in August QST -
Microwavelengths)
basically, a distant signal is reduced in 1 dB steps with each station
recording the
level where it is no longer audible. then it is moved in frequency a few
KHz, and the
level increased in 1 dB steps with folks trying to find it again.
with the Flex, I lost the signal 2 or 3 dB before the best stations, but I
found it again
at the same level, using the waterfall display. the other stations, by
ear, needed
about 5 dB more signal to find it coming up out of the noise - a typical
difference.
I could not hear any signal when it first appeared in the waterfall.
this should be great for portable operation.
I was running this on a Netbook, making a nice portable package. the only
problem
is that the PowerSDR display is bigger than the Netbook screen in the
vertical
direction. any way to make display size an option?
now for the two meter transverter for the microwave IF. I dug out my
Miniverter
(www.w1ghz.org/miniverter.zip) and am considering updating it to mate with
the
Flex 1500. any interest?
