You may have to experiment to find the proper value resistor. This indicates a normally closed audio line, a very undesirable feature. For electronic switching this is exactly the same as described above but without the benefit of already knowing the common connection. We look forward to seeing you soon! Contact us by email: click. Some older relay switched rigs used a small shielded cable between the mike socket and main chassis, a dead giveaway that those are the Mike line and Ground. Otherwise if you cut back an additional inch or so from the main cord cover, youll most likely see one wire thats wrapped with the shielded wire.
The cure is obvious: tune or fix that antenna! One color should show a short; i. Note: Many power mikes will show a mike line reading of a few ohms all the time until you key it. We thank you for your support! Make sure you visit my for advice and technical tips, such as repairs and mods! We recommend anyone interested in old receivers join a local vintage radio club as well as a national club such as the Antique Wireless Association. You may also see this in the unkeyed position. In these rare cases, there will be voltage to ground on two pins instead of just one; touching either of those pins to common will make the lights go out or blow the fuse. For example, the red wire on an Astatic mic is the Transmit wire, on Turner mics it's the common, and Cobra uses it for the audio lead.
But what if the mic is on it's third cord, who knows what color code the last owner used, and what if your brand of mic isn't listed. Some older relay switched rigs used a small shielded cable between the mike socket and main chassis, a dead giveaway that those are the Mike line and Ground. And it shows a few ohms of resistance. Registration is quick and easy and 100% free, so today! On a 4-, 5-, or 6-pin socket thats relay switched, those remaining pins are either unconnected, or possibly also grounded. You can also confirm this in Step 4 below. In any case, only four wires are actually needed.
I tried taking it apart and looking online for info, and for some reason this mic is a mystery, not 1 video from anyone on how these mics are wired or how to wire them. These will easily fit inside the mike. Use the Rx1 resistance range. Youll need a real antenna or a Dummy Load, a clip-lead or a piece of bare wire, and possibly an Ohmmeter. Solder and tape all your connections.
Note: Turner mobile mikes dont have the internal switch, although some of their base mikes do. Solder and tape all your connections. This link will open in another window To the Members Area. You should discover that two of the three colors will short show continuity when keyed, and two of the three will short unkeyed. On a power mike, the battery must be installed before trying any Ohmmeter tests. If you are told you are spam when registering contact us at the contact us menu link above!! And is also more expensive. Start touching the other end of the wire or clip-lead to the remaining pins briefly and watch what happens.
To begin, figure out which pin on the mike socket does what. All Turner mobile mikes work this way. Check for breaks or damage to the plug and cord. In many cases, installation of a resistor of about 4. The cure is obvious: tune or fix that antenna! The remaining wire you aren't testing is your transmit lead.
Hey my mic only has 4 wires! You may also see this in the unkeyed position. Its usually done because the manufacturer was too cheap to use a switch with enough contacts on it to begin with. Immediately draw a sketch of the socket, using its notch as a reference point. We will continue to try to get all the information that we can listed on this page. Start touching the other end of the wire or clip-lead to the remaining pins briefly and watch what happens. See the inset in Figure 3. Use your Ohmmeter to touch the remaining three colors with both test probes.
The remaining color is obviously the Mike or audio line. By the way when looking inside the radio, you can just as easily find the common or Ground by noting which pin the shield of that audio cable is attached to. Those models are specifically designed to let you hear yourself in the speaker so you can adjust an Echo or some other audio feature in the radio. If it doesnt, cut back another inch or so of covering; youll find it. Step 3: Strip back that common color and twist it together with the shield, making this a single wire.
