Hi Andy,

I understand the points you are making, but having previously discussed this with Philippe, I think there are some valid concerns, that may discourage other people, in other countries, from operating a KiWi.

If a simple fix, which John has already implemented, can help remove some of these barriers, then surely it is a good thing ?

Some countries are extremely sensitive about some aspects of the radio hobby, and to be honest, if I was living in one, I wouldn't be running a KiWi. It's easy to forget this when living somewhere that is more "relaxed" about such things.

Callsign piracy has always been an issue, and using an alpha-numeric string (or emojis) to identify an individual doesn't mean that they are who they say they are. However, I can understand the problem for the KiWi admin, if someone else decides to use your callsign, and you, the legitimate owner, find out, and then blame the admin for something that he has no control over. This may sound unlikely, but I have experienced similar problems when we had the "Chat" facility enabled on one of our websdr's, which caused so many issues we, (like most other websdr admins) removed it. Any public site, that has the ability for folks to anonymously post comments, no matter how brief in content, will unfortunately be abused.

Andy - "they" already know, who you are and where you are :-)

Sometimes, when used inside a Switched Mode Power supply, the additional choke inductor in the ground (L3 in the circuit) can sometimes be more problematic than useful.

I tend to wire the DC 0v / -ve directly to the mains earth, but depending upon the local configuration, this can also make things worse.

Unfortunately, it's one of those cases where, although it may be good practice to do certain things, you generally have to experiment, in order to find the best solution for your own setup.

Fldigi has a decoder, but I note that there are a number of Linux based parsers and decoders too.

Hi Philippe,

I'd agree with John that it doesn't make sense to list KiWi's that folks can't openly use.

But I do understand your reservations, and some countries are definitely more restrictive than others.

Short range local VHF / UHF communications are certainly more problematic from a legal perspective than HF communications, which generally tend to completely ignore geopolitical boundaries

Maybe it would be worthwhile emailing some of the other KiWi admin / operators in France, to see if they have the same concerns as yourself ?

A bit more information for those interested in Wave Radars, cut an pasted links from discussions on other sites.

CODAR and WERA (now Helzel) are very similar systems, and I think that folks tend to call all of them CODAR, a bit like some brand names becoming used for all products of a certain type regardless of the actual manufacturer.

There are plenty of WERA systems operating, but maybe not in the USA, even so the chances are you will have heard one, but thought it was CODAR.

You can also use this map.

https://cordc.ucsd.edu/projects/hfrnet/

Select station placemarks in the overlay menu to show them on the map.

If you click on each map pin it will give you more data, including the operating frequency.

Alternatively, there is this list, but it takes a very long time to load.

WERA have a range of products, some of which have slightly different characteristics.

The European ones are listed in a table at the end of this document
