Any better site than Leif's site for digital mode identification?

[KE7IZL]

Leif's website signals.taunus.de seems to block my IP address, even though I'm not a spammer or bot, and have never tried to use any software to dump his website (something he expressly forbids) nor any other automated techniques for accessing his website. His site was great for signal identification back in the early 2000s. It's useless for me now though, unless he unblocks me (I've already sent him an email, and am waiting for a reply).

If I can't get to his website anymore, then I hope there's an alternative of some kind. His station info about each mode, including obscure/rare ones like ARQ-E. It had not only audio samples, but also spectrum images, and even correlational images. I've never found any other site with this much info so many other modes. Other web sites have a decent amount of info, but nothing as extensive as this guy's website, and most only talk about some of the more common modes like ham radio modes and a few of the more well known commercial/government type modes such as Pactor, ALE, etc.

Last time I checked was probably around 2010 or something, and then just gave up on his site. I checked again today, hoping I'd be able to access it again, but I can't. So now I'm just hoping that somebody else has also posted a website somewhere with just as much extensive info on an equally large number of HF digital modes (including the more exotic ones).

Mine is blocked too (for like ever) ...was a vy good site , I have not seen him on WUN
in a very long time ...try joining WUN club on IRC chat or UDXF,
I use to use it to, it was a great site for identification of dig sigs. then
one day it just blocked me...long time ago ...vy long time.
anyhow try joining UDXF on IO it,s great for info like you mention.

Maybe you could share the URL?

@Teotwaki - It is there in the very first sentence.

@KE7IZL - I could not get in either regardless of VPN location, browser etc. What I can do is use the Wayback Machine and found a date that does have the site archived with digital audio samples. Perhaps use this for now until you find something better. This archive is from May 2007. There is sure to be a site with the newer modes.

Thanks for the info "Vagrant" helps me too...73,s Marcy

 

[Teotwaki]

I don’t think anyone is being blocked in a personal sense. I suspect the site is no longer maintained and no one can gain access.

 

[Marcy57]

In my case this was when it was active and still being used and updated
just one day blocked me and I used it all the time...just gave up ...Marcy

Signals - The HF monitoring site

Here's the real problem with that. It doesn't have the latest modes available that the website actually had. Before I stopped being able to get access, there were modes available there that aren't available on the last Wayback Machine copy of the site. At some point the Wayback Machine got blocked from the site and so was unable to archive everything. There's missing WAV files, spectrograms, etc. Some of these are only from modes that ever were available at www.signals.taunus.de and so the only place they exist now is in my memory. They may be lost to history, unless somebody else also received and recorded the same modes.

So I'm hoping that somebody else on this forum knows of an alternative to that website, containing extensive info on an equally large number of different HF digital modes. Hopefully in the years since that website became unusable, somebody else has stepped in to fill the void.

A good place to go with unknowns is at reddit in signalidentification. I and other lurk there and help. In fact some of us figured out modes before they were known just by looking at them (in my case ARQ-E which I figured out when it was not so rare_. With new modes always appearing, most websites have trouble keeping up.

UMmm what ever happened to 'sigid wiki' ?

Signal Identification Wiki

This wiki is intended to help identify radio signals through example sounds and waterfall images. Most signals are received and recorded using a software defined radio such as the RTL-SDR, Airspy, SDRPlay, HackRF, BladeRF, Funcube Dongle, USRP and other devices.

Librarying radio signals is like trying to library all existing books and expecting a person to know how to use it. Many will come to a wrong conclusion (often by picking what looks "closest"). The reddit place gets people who will recognize a mode that is not at the other pages and try to analyze it (what I do)--often successfully.
One of the big mistakes that many make is thinking a waterfall is an identifying signature. In fact, it is only one tool and a limited one as settings of the receiver can make the signal look completely different ; and different signals can have essentially the same waterfall. It does show bandwidth and other things but a sound file is essential. And an IQ file often crucial. One thing people forget (even on reddit) is that location is essential (and even some forget frequency anywhere in their post).

Also, another excellent references that many do not know is the updated every year or two
are the books by Proesch. He covers HF. VHF/UHF, and satellites in separate books. These are far better than any website in identifying unknown signal. Though not cheap, they are very worth it.

I have the 2020 "Frequency Handbook for Monitoring HF" from Roland Proesch and it is
excellent.. and a big help...73,s Marcy

Up until this thread I had never been there yet it immediately showed that "no access" screen you spoke of occurring in 2010. That says that probably 99 .9 to 100% of the entire world is automatically blocked.

It's likely that it's nothing personal and that:

Leif took the site private on or before 2010 for only a select group of his closest friends
Leif stopped maintaining the site and could care less about it
Leif is dead and the web site just hangs there until the server crashes.

His "Technical" handbooks are very good for identifying signals with the "Frequency" ones giving frequency lists. By the way, I have the 2022 Frequency Handbook and I think he may have or will release a 2023 edition--it is hard at the website to get the year of the most recent one. (Be careful as eBay and Amazon sell older editions.)

Regarding the site in the OP, he's using HTTP which is insecure and most browsers aren't going to play well with that. The browser is probably facing a challenge that it's ignoring because the web page is insecure. If the guy was still maintaining it, he could simply get a signed cert, put it on his site, disable HTTP and force HTTPS. There was an amateur guy posting in one of the GMRS groups on Facebook that had a similar situation. He just didn't know any better and was hosting the page himself. I gave him that information, he applied it and now his site is accessible again. It's nice to see there's other options though. Pretty cool.

I also have (old) Monteria 2005 HF Monitoring Handbook thing is huge alot of good info yes some outdated like most but I still go to it, Klingenfuss several handbooks (many years of his books on my shelf)
and the book I mentioned from R. Proesch ...from what I understood from postings Leif D. is still around but
he moved to a qth with alot of qrm and guess? that curtailed his monitoring ? thats how I understood it?
good dx to all 73,s Marcy

And again, no one has mentioned searching the Utility DXers forum logs to see if a particular frequency with that mode had been reported. Yes there is a search feature and the logs are downloadable as plain jane text files every month.
