You will have difficulty decoding anything from that signal, it is US Navy, 850Hz shift 50bd KW-46 Encrypted, Lualualei, Hawaii.

Try using some of the KiWi's preset stations in the FSK extension, to get a better "feel" for the different shifts and baud rates.

The most common FSK signals tend to be Russian 200Hz (or near) shift "BEE" format.

If you click on the column headers Internal / HF / External on the http://rx.linkfanel.net/ webpage, it will sort that column in descending order.

Personally, I like to sort by the HF value, as that is often a better indicator of actual performance.

However, the whole SNR measurement process can only really be used as a rough guide, and unfortunately the majority of KiWi installations are badly let down by poor antennas, often in very noisy urban locations.

The KiWi's in the top 10% (70 out of approx 700) SNR scores, are generally OK, but some of the rest are really awful, which is a great pity, and IMHO a great waste of resource.

Purchasing a receiver is only a very small part in the overall process of receiving signals. Although you can't really do without one, even a top of the range model, isn't going to make up for a poor antenna.

Signal to Noise Ratio is what matters, not absolute signal strength. Good transmit antennas don't always make good receive antennas, as they are required to do different things.

I'll keep on repeating this mantra until things improve, but I suspect I'll die first...

The port is defined in the actual device configuration file.

Some port numbers are used for specific purposes, like 80 for web pages or 22 for SSH, others are chosen and sometimes become a defacto standard, but the can be changed if required.

Imagine your IP is like a street address for an apartment block. The port number defines which apartment within the block is the actual address to send and receive mail.

With SDR++, you simply use the same url format you would use to connect to any other SDR+++ server, bur with your IP details instead, followed by the port number :5259.

You should be able to connect to your own server if both devices are using the same local network.

If you wish to connect outside of this, over the internet, you will need to add a port forwarding rule to your router.

The KiWi makes this easy, by offering a number if options to configure this function.

Which KiWi is your own KiWi, where is it located, and is it public ?

Thinking about this, as this forum only allows limited information to be included in our profiles, it would probably be a good idea for folks to include their KiWi URL(s) in relevant posts.

Two or three times an actual MW broadcast frequency is often observed when very strong local transmitting stations are present.

In this case 3 x 1278kHz = 3834kHz

Sometimes these are actual harmonics being radiated by the transmitter, sometimes they are externally generated by objects such rusty wire fencing, that is rectifying and re-radiating signals, and sometimes they are produced somewhere in the reception chain.

Many times it can be a combination of all of the above.

Placing some attenuation, or better still an amplitude / frequency slope equaliser ahead of the affected KiWi can often help to minimise such problems.
