Ah yes I missed the other thread, I got confused because I'd been following a similar conversation on another forum regarding the loss of Google maps.

They had suggested Leaflet (an open-source JavaScript library for mobile-friendly interactive maps) https://leafletjs.com/ as being worth looking at, but I'm sure there are many other contenders too.

I think this decision may actually cost Google more than they may gain in the long term, and it's not as though they really need the money either.

Hi John,

I have a test setup running on http://g8jnj.proxy.kiwisdr.com:8073/ with two AM signals being modulated by a CW recording.

TEST TEST TEST 1234567890 THE QUICK BROWN FOX JUMPED OVER THE LAZY DOG

The two signals are at different levels

3598.00KHz @ S3

4548.00KHz @ S5

I can get good decodes (just) on 4548.00 with 50Hz BW and a threshold of 42 but 3598.00 is too weak.

I'll leave it running so please feel free to use it for your own tests as required.

Hi Lonecrow

Try http://g8jnj.proxy.kiwisdr.com:8073/

It's a very quick and nasty lashup which is lying on the floor of my workshop so there is a lot more unwanted noise and hash than there should be.

VHF 144MHz band antenna, 100m of coax to workshop, 20dB low noise preamp, VHF BPF filter (6dB loss) , 10dB preamp, FM BC Band notch, 10dB preamp, Mini-Circuits Mixer, 115MHz LO injection from a signal generator, 40MHz LPF & into the KiWi.

I've edited a few DX labels with local airports, but I've not done anything fancy with removing or editing the HF Band markers etc.

Best performance is between about 120-130MHz as I had to quickly build a band pass filter to remove the FM Broadcast Band and it's not very good.

I'll leave it running for a few days until I need it for something else.

Have fun,

Thanks John,

That makes a huge difference to the speed and ease of use of the TDoA function.

Much appreciated.

Hi John,

I was thinking about the possibility of using the KiWi with a down-convertor.

Some of the existing extensions are not that useful if the short wave bands are not being received or if the antenna isn't suitable for reception of stuff like Loran. Also the Development controls extension is always listed but hardly (if ever ) gets used.

Would it be possible to add an admin option to Enable / Disable individual Extensions and clear them from the drop down extension list ?
