OpenWebRX [using a transverter/down-converter with the Kiwi]
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,

Suggestion - Admin option to Enable / Disable individual Extensions
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 ?

Not really interesting.
Ooops, I should also have added this YouTube link which shows you how to use them.
Although this shows them being used with a printed circuit board, you can do the same thing with power supplies, cables, PC's etc.
Just be aware that the KiWi takes time to process the signals, so there will be a delay of 1-2 seconds between you moving the probe and seeing a change occur on the waterfall or spectrum display.
