Ionospheric Heaters?

Hi Ron,

As far as I'm aware DARN is only occasionally used these days when they can afford to put some money in the electricity meter.

However there are a whole host of other atmospheric sounders and radars that can be heard almost continuously.

Here is a quick guide to some of the more obvious ones.

How do you use your SDR

Hi All,

Mine is fully public 99% of the time.

I don't think the bandwidth used is excessive, but I'm on a VDSL service with no user cap (as far as I'm aware).

Hi All,

Mine is fully public 99% of the time.

I don't think the bandwidth used is excessive, but I'm on a VDSL service with no user cap (as far as I'm aware).

However it does get very high usage and sometime I have to kick users off so that I can log in and use it myself.

I have a particular problem in that a lot of Dutch music pirates use my SDR all day long to monitor their own transmissions around 6MHz.

What I really need to be able to do is to be able lock out certain frequency ranges or restrict the amount of time individual users can stay on the SDR before getting automatically kicked off. I currently have the inactivity time out set at 15mins but I may have to reduce this still further.

I now have a second Kiwi on order, so it would be good if I could link them in some way so that they both appear as one Kiwi but with eight possible connections.

I previously raised this suggestion in this link https://github.com/jks-prv/Beagle_SDR_GPS/issues/48

I know that there is at least one other station running multiple Kiwis on different ports so I don't think I'm the only Admin who may be interested in this idea.

Most of the time (when I can log in) I use my Kiwi for general short wave listening and enjoy spotting 'unusual' activity on the waterfall. I also enjoy listening to NDB's, BC stations and Amateur stations. Quite a few of my users seem to listen to HF Aero traffic as well.

I note that quite a few folks use the WSPR extension (logged as SWUKSDR) especially on the 472KHz band. I've also got antenna switching and this gets used some of the time mainly by the BC listeners in order to try and reduce interference or other stations that are co-channel.

I think the KiWi has been an excellent purchase and It's certainly re-awakened my interest in Short Wave Listening.

Well done John, and thanks for all the ongoing support and rapid resolution of any problems that may occasionally arise :-)

Hi James,

Your notches are doing a great job, as your SDR seems to be a lot happier now :-)
