Each of the DXE filters contains two filtered Halo HFJ-1G46ERL RJ45 sockets wired back to back on a small PCB.

Pin 10 seems to be left floating in the DXE design.

Everything is inside the box as shown by the dotted line.

I should have clarified the way it works a bit better.

Pushing the mouse wheel down whilst rotating it enables the opposite mode to the default that has been chosen. in OpenWebRX.

Having the possibility to tune using the mouse opens up other possibilities such as making your own VFO knob, using the optical encoder recovered from a scrap mouse, or buying one of the more expensive ready-made commercial items.

If it could be implemented in a way similar to that of OpenWebRX , then it would still retain the mouse wheel zoom option for those who prefer it, but offer an alternative for folks who would like to use mouse wheel tuning.

Try it and see for yourself.

If you open up the settings pane in the control panel, you should see the "Hold mouse wheel down to tune" tick box. Also set the tuning step size in the controls section, 500Hz or 1kHz is useful for SSB, as most folks use 'rounded up' frequencies.

I'm not specifically requesting this feature, as I don't wish to add to John's already massive workload of much more important issues, but I can understand the appeal of it.

Hi All,

Details of my 'Loop on the ground' (or technically just above it) can be found on this webpage.

https://www.g8jnj.net/loop-on-the-ground

Treat the page as a preview as it's more of a working notebook and not really fit for publication yet.

It may also contain some errors and content that will eventually be removed if I decide it's not really worthy of inclusion.

I hope it may encourage other KiWi owners to experiment, as I've found it to be about 10dB more sensitive than typical 1m diameter loops. Although it's still about 5dB below the sensitivity required to hear galactic noise throughout the 20-30MHz frequency range.

The S/N stats on http://rx.linkfanel.net/ (although not very accurate) currently show my KiWi and LOG to have a value of just under 32dB, which is probably amongst the best of all KiWi's worldwide.

For comparison purposes most Kiwi's using 1m loops shown on the site typically manage around 20dB and most E-Probes achieve about 15dB.

You can take a listen to my KiWi using a 10ft per side loop and pre-amplifier on this url http://southwest.ddns.net:8073

Hi All,

The Russian RSDN-20 beacons on 11.9, 12.65 & 14.9KHz are active once again after quite a long absence.

They must have found some more coins for the electricity meter down the back of their sofa.

Signals are about 8-10dB above the noise floor on my Kernow KiWi SDR in the SW of the UK.

If you use this URL it will provide enhanced contrast on the waterfall display.

The signal on 14.9KHz seems to have a second weaker transmission slotted in between the stronger 'pips', which you can just about see in the screen grab.
