I often find that I listen to one frequency whilst scrolling up or down the adjacent spectrum. If I quickly tune to a new frequency to hear what's been transmitted, it would be good to be able to quickly go back to the previous frequency without having to scroll back or retype the frequency (which I've often forgotten anyway).

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 :-)

Just about a long enough a delay to cause you to hesitate whilst speaking if you are monitoring your own transmission.

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

The patch antenna supplied with the KiWi doesn't seem to be as good as some other GPS antennas.

A lot of modern double glazing uses a metalised film to provide additional heat retention, but this also has the effect of greatly reducing the strength of GPS signals.

I rarely used to get two satellites at any time with the supplied patch, but this week I ran in some more cables so that I could split the feed from an existing Trimble GPS antenna and now I'm typically seeing six at any moment with four or more at good strength most of the time.

I would like to be able to switch antenna ports directly from the BB GPIO pins via the web interface and also change some text on the web interface if some of the BB GPIO pins are switched externally.

Kari, OH1KK, has done a great job in writing the Kiwi extension to drive a MS-S7-WEB antenna switch . But I really don't want to be tied to specific hardware as I've already got a number of different peripherals that I'd like to control & monitor directly from the KiWi.

Is there an easy way (I'm not a coder) to modify Kari's extension to drive and receive commands from the BB ?

That's really good :-)

Here's my fix.
