• silly question

    From Jake T@21:1/5 to All on Tue Dec 14 05:17:57 2021
    Maybe a silly question, maybe not, but thought I would ask anyway. As I indicated in one of the prior posts, for this week at least, I've been
    trying to capture audio of the coyotes on the landscaper's equipment
    grounds, something I got permission for last week and places me a lot
    closer to them. However, at home, which is probably 200 meters or so
    further away, I'd like to be able to monitor the outdoor audio from
    inside. Right now, I have an old Radio Shack dynamic 1/4
    mic plugged into an old guitar amp I had in storage. There is weak
    gain as I have to turn the amp all the way up for results, but it does
    sort of work with a lot of hiss of course because the match is so poor,
    plus the whole set up is unwieldy. So, looking for something simpler, a
    lot smaller, sensitive and cheap to monitor the outside from indoors.
    Does not have to be perfect as I won't be recording from it. What would
    you use? Thanks.

    I'd be looking at radio mics. They can be pretty cheap. Wrap the mic
    itself in cling film (Saran Wrap?) as it probably won't thank you for
    a rain shower.

    Depending on what you buy, it will probably be good enough to record
    from.

    If you have permission to run a cable, use the headphone/ aux output on
    the H2? Gives you proof the unit is working as well.

    Otherwise, a pair of walkie talkies, though as one needs to be
    permanently transmitting, battery life may be a problem.

    Another alternative, a short shotgun mic in a "dead cat" with the
    longest cable it will drive. Some of the cheap camcorder mics can drive
    a reasonably long cable and are not too bad for directionality.

    You might be pushing your luck to get reliable transmission from a radio
    mic over a distance of 200 metres and then through the walls of a
    building (unless much more power is permitted than the 9mW limit which
    applies in the UK and a lot of other countries.). Increasing the power
    of the transmitter will use up batteries too quickly and mounting the
    receiver outside will involve bringing power and signal cables through
    the walls.

    If you know anyone with R.F. experience, you could get them to help you
    mount the transmitter section of the mic in a waterproof box with a
    balanced and tuned dipole aerial on a high pole. That will give a much
    longer and more reliable transmission path (easily up to 1/4 mile, in my experience).

    Sorry, I should have said that this would be just on the outside of my
    house, so little distance involved. I was thinking of a wired electret
    with the wire fed to a small amp, or something I can throw together
    myself. I have a spare set of amplified PC speakers I'm not using.

    No recordings, I just want to be able to hear what is going on just
    outside my house. With the dynamic and guitar amp turned to the max, I
    can hear the coyotes when they howl at the remote set up. The idea is
    to go change out the SD card of the H2 should the coyotes howl.
    Unfortunately, I can't use VOX on the H2 as they don't get close enough.

    I have a couple of GMRS radios I don't use, but I think that would be
    the wrong band for continuous monitoring. Maybe a sensitive FM
    transmitter that I can tune in at the bottom or top of the FM band.
    Just outside the house will mean it doesn't have to have much power at
    all, but would the electret be sensitive enough is the question.

    I used to design radio equipment for use in spacecraft, and also TV
    networks during a break. 300 feet across a field is trivial, and the
    receiver can be stood in a window so there are no building parts to
    kill the signal. Worst case the receiving antenna can be replaced
    cheaply with a directional one, which will have masses of signal gain.

    I should have been more specific before. I just want something outside

    kill the signal. Worst case the receiving antenna can be replaced

    The transmitting aerial in most radio mics is pretty inefficient and you
    would be very lucky to get a reliable signal more than 150 metres away,
    even across an open field. You would probably get some sort of signal a
    lot further away, but it might be noisy and subject to fading, or the
    positions of the transmitter and receiver might be very critical.

    That was why I suggested using a proper transmitting dipole to make the
    best use of the available 9mW. [I was assuming this was in the 175 Mc/s
    band.]

    In that case, just add a cheap mic preamp and your guitar amp will cope
    fine. Guitar amps are high impedance, which doesn't matter, but are
    designed for a higher input voltage, which can be done by using a single transistor in common emitter mode, which needs four resistors, two
    capacitors, one transistor and a couple of AA cells or other small
    battery for power. The diagram will give you an idea, but you will need
    to work out the values to go with your available power supply voltage. I
    have all the parts in my junk box....

    A cheap shotgun mic will give you a bit of directionality, but no extra
    gain.

    gain as I have to turn the amp all the way up for results, but it does
    sort of work with a lot of hiss of course because the match is so poor,
    plus the whole set up is unwieldy.  So, looking for something simpler, a lot smaller, sensitive and cheap to monitor the outside from indoors.
    Does not have to be perfect as I won't be recording from it.  What would you use?  Thanks.

    So.... my neighbor had a nearly brand new baby monitor she gave me for
    free! It is a Vtech dm1111. I just tested it and it seems sensitive,
    but I wonder if there's a way to increase mic sensitivity? There's
    certainly no way to do it externally. I won't know for a few hours
    whether or not it will be sensitive enough to pick up the coyotes, but
    will find out. It's far more quiet than the guitar amp and dynamic and
    takes up far less space!

    Well, babies and Coyotes sound pretty much identical to my ear, so it
    should be pretty good.

    Pried it open, all surface mount. Thought I might find an internal gain control but no. It's probably going to be ok though. I think it has
    similar sensitivity to the other setup but far less noise is the reason.
