      I've been thinking of using my Magenta Bat5 detector (see
      www.magenta2000.co.uk for details) and feed the constant level output to a
      digital recorder, but that only gives an audio conversion of the received
      frequency of course.

      I have, in the past, also built a detector based upon a cheap ultrasonic
      transducer (sold in pairs, one transmitter and the other a receiver) and
      I've considered getting another one to connect to a length of cable to point
      out of the window.

      The problem with large external soundcards, for me, is carrying them and the
      PC around. Even a notebook is a bulky thing to lug about and set up in the
      evening when the bats typically come out.

      There are other detectors, some of which are very expensive and aimed at the
      profeesional/achademic bat watcher and these are well out of my budget...

        Hi Steve

        Since the rapid expansion of white nose syndrome the public in Canada has been requested not to enter bat caves, most people are complying with that wish.

          Bonjour, je suis un nouvel inscrit à SpectrumLabUsers. Je m'intéresse au VLF. Pour pouvoir enregistrer sur des points hauts, j'ai un enregistreur numérique Olympus dont la caractéristique maximum est 96 kHz 24 bits. J'ai fait des essais avec enregistrement en direct avec ordinateur portable et l'enregistreur. Je n'ai pas vu de différence. L'antenne cadre est branchée à l'entrée micro. Si le signal est trop élevé, il y a un attenuatteur sur l'Olympus (modèle LS-5). Comme l'enregistrement est stéréo, je supprime un canal avec Audacity. Rentré chez-moi, je peux voir le résultat en branchant l'Olympus sur mon ordinateur portable, soit par la sortie haut-parleur soir par la sortie USB. Donc je pense que les micros internes montent très haut, sinon, utiliser des micros ultrason pour alarme, vieilles télécommandes TV, appareil chasseur d'insectes etc.
          Excusez-moi, je suis nul en Anglais.
          Amicalement

          George, I bought mine at Florida Sound, but Amazon has it for 89.00USD, about 45% of retail. It s a great unit. I m using it for monitoring five VLF stations

            It's a great unit.  I'm using it for monitoring five VLF stations from the Omaha area.

            Hi Wolf

            Many thanks, I'll see if I can find a local dealer for E-Mu (I can remember their first music synths) if not I'll have to shop on line.
