I would suggest the option of inhibiting TX unless the FlexWire PTT pin is
based, along with the normal Delay PTT that is already in the software
(and not working). This allows for the flexibility required with expensive,
complicated sequenced systems. PTT-Out should still go to ground when
I have noticed at times (particularly during fox hunts) what I can best
describe as a noise hill that usually drifts around in frequency. For a
width of several KHzon the panadapter I see what is shaped like a normal
curve that trails off for many more KHz. In panfall mode I can see a
brightening

I've seen that too. The ones I've seen do drift, but very slowly and you
can hear them - a low frequency noise. But . they do not appear on
either the K3 or the K2 - all running on an Astron RS50.
I also hear (and see) birdies on the 1500 that are not there on the K2 or

One of the things I have noticed with the 1500 --- when I see birdies on on
the panadapter on a given band, if I increase the preamp gain a step they go
down into the noise. I gave on the acer aspire one netbook and got a Toshiba
crossover (sized betweeen a netbook and notebook) with a

The noise hump that wanders around is usually a switching power supply, and
not necessarily the one powering the radio. Switching wall-wart supplies
are especially bad.

In order to have the folks at FlexRadio to only have to 'fix' this bug once, I
have put together a quick document outlining the scope and requirements. I
believe it covers what needs to be implemented in PowerSDR and the Flex-1500 to
allow reliable sequencing of external equipment,

First thing you need to do is power the radio and computer from a battery

Thanks, Brian, this is all excellent advice and it's actually what I

each, and yes, there is a grounded cable entry plate with lightning

Yes, Power out is only reported now on a percentage value.

Hello Mike,
For over a year, I had a problem with 'noise hills' mostly on 40m. The
peaks were spread approx 60 KHz apart and their amplitude was about 10
to 15 dB above the normal noise floor. They would go away completely
every few days for a couple of hours, but they always came back again.
An update on my noise hills: I put a dummy load at the antenna end of the
coax, and they aren't there any more. There are some other quirks that can
be seen but of a much different nature that are probably switching supply
generated and some internal 1500 artifacts.
Thanks again to all who
Call the power company and have them shut down their generators!
