  • About
    I am a still photographer working on collecting visual and aural ethnographic materials. As a researcher my work is inspired by the work of Alan Lomax (ethnomusicologist) and John Collier Jr. (visual anthropologist). My aural research interests include folklore, oral history and photo-elicitation.

    I am working to tune my ears to the rich world of sound. I am learning to record dialogue and natural sounds. In recording dialogue, I strive for high quality recordings, but the captured “spoken content” is often more important to me than the nuances of microphones. That said, I often record in the field and face some of the audio challenges that location sound people do.

    What interests me the most about participating on this site is to increase my audio knowledge and to understand the way the members solve complex issues that they face in their work.

    Sincerely,

    Mark Kirchner

    I have built BNC antennas before. Here is a photo of a BNC antenna that I made attached to a Lectrosonics ground plane antenna.

    Rachel, Replace the metal screws with nylon screws. They still may burnish the finish of the microphone. Good luck. mark

    50 Ohm coax.

    You can see that soldering on the circuit board one needs to be very precise. This is a G3 I did a few years ago.

    What I think Glen was meaning to say is a dipole antennas made from 50 Ohm Coax cable. The Lectrosonics YouTube site has a DIY video on the subject.

    Wilcox Sound will re-wire your Cos-11d for about $150 if you still think there is some life in it.

    Judge, There is a lot of information on this site with regards to your question. Use Google like this> gain staging jwsound or g3 set-up jwsound The key is to not use the internal search tool from this site. Once you know the secret there is years of good reading and knowledge here. Good Luck

    Jon, I had an internal boom cable that had a nasty kink in it. I coiled the section along a smaller diameter wooden dowel, then heated it with my hot air gun. It got pretty warm, then I plunged it into a bucket with water and Ice. The cable came back to the original form. I hope this helps. Mark

    Roubi, I have made antennas from nitinol nickel-titanium wire, but decided to use small diameter multi-strand cable instead. I understand that you are making antennas for receivers, not transmitters at this point. When I made nickel-titanium antennas, I would file a series of small notches in the terminal end of the wire. The notches would be covered by the SMA pin after soldering, but would add a mechanical bound inside the soldered connection. The colored caps are sold at B&H in New York, made by Lectrosonics I think.

    Roubi, Here are some of the antennas I make. One of the tests I do is to put the SMA connector into a vice and then I lock vice grip pliers on the antenna wire. I then try to rip the antenna wire out off the SMA. Lectrosonics antennas are super strong. I pulled a Remote Audio antenna wire out, but it was difficult. Mine are 3rd place so far. You might think it is crazy to put a $40.00 antenna in a vice and then try to destroy it, but I wanted to know. I also did not want "talent" pulling an antenna out.

    Hi Martin, We will just have to see how this all plays out. Mark
