QRM: Radio China International - From Albania - OV +++
Hi Giulio,
Adding a series tuned notch filter across the KiWi RF input will help reduce the problems on 7345KHz.
These values give the bets compromise between notch depth and attenuation on the… (more)

No, you need to either notch out the strong signal which has a minimal reduction in overall performance across the whole frequency range, or put an attenuator in line which will reduce the… (more) -

Monitor Battery Voltage At Remote Site
I've often wondered if it would be useful for the KiWi to be able to present a simple webpage in place of the existing top bar which has limited formating options.
Perhaps this could also allow… (more)

Re-designing the OV marker space?
Hi John,
I wonder if it would be worthwhile bringing the OV indication out to one of the P9 GPIO pins ?
It could then be used to drive an external attenuator circuit via a suitable averaging circuit,… (more)

OpenWebRX [using a transverter/down-converter with the Kiwi]
Hi Lonecrow,
That doesn't sound good.
If you open up thew new Signal Generator extension and switch it on using the default settings you should see a carrier at 10MHz on the waterfall with a level of… (more)

OpenWebRX [using a transverter/down-converter with the Kiwi]
Hi Lonecrow,
OK that's good so it doesn't look like anything major is broken.
I'd suggest that as you are making a lot of changes to the config, it may be a good idea to buy a few decent quality SD… (more)
