Some have five conductors in the Mic cord and some have three conductors. I got one yesterday that has me stumped. With per say amplification I could talk all kinds of places. See the inset in Figure 3. It only takes three connections. You may also see this in the unkeyed position.
Draw another sketch and mark both those pins. The order is: 1, 4, 2, 5, 3 The following chart will tell you what pin does what in a Radio Shack rig. It Worked the last time I used it!!

Touch the other Ohmmeter test probe to all the mike socket pins. Wiring color code or symbols, wiring harness, radio and audio wiring, circuit diagram, light switch wiring diagram. Not any ground wires or shielded. The obvious way is to look at the main chassis for a relay.
Check the pins in the radio for damage as well. Its high output voltage was characteristic of crystal elements and its high impedance allowed for direct grid input. You can see the connections below and some notes. Manufacturers use the cheapest parts they can find. Generally speaking, its much better to buy a mike wired for electronic switching. It is a 4 pin, the colors of wire are red, white, black, yellow, green. Mark it on your sketch.
I hope that this is very helpful for you Best regards Michael These Astatic D-104 microphones are all vintage. Crazy thing was that the leader and the guy between me and him were not able to talk to each other directly, and I could talk to both of them. This will have the shield wrapped around it. Determine which color wire on the new or repaired mike performs that same function. A quick Ohmmeter check after you find the mike line will reveal that you get a complete circuit continuity between the two remaining colored wires, rather than one color and the shield. The d104-M6 has easily accessible rear control for volume adjustment so that the correct modulation level can be set for each operators voice. If it doesnt, cut back another inch or so of covering; youll find it.
Each pin timer has wiring diagram. Solder and tape all your connections. On a power mike with the battery installed, the resistance may vary anywhere from a few ohms to several thousand ohms, depending on the setting of its gain control. Start by jumpering any two mike socket pins together and see what happens. On a 4-, 5-, or 6-pin socket thats relay switched, those remaining pins are either unconnected, or possibly also grounded. Also if your radio keys up when you plug mic in reverse the black and red. To say that it worked the last time they used it is a good use of for the seller but bad for you the buyer.
It has a small transformer, no markings. Continue jumpering around until you hear a normal receive signal in the speaker. The word common as were using it means the same thing as Ground or shield wire. Youre looking for the wire that shows a kick power mike or a fixed resistance reading standard mike between it and the shield when keyed. I bought a Singer sewing machine foot pedal switch and will wire that in as the reason I did not want to use the mic was the grip switch. Youll find one or two pins that make the meter deflect all the way over to 0 W.
They stand for Relay and Electronic. Following are some typical examples. In any case, only four wires are actually needed.

Image is not clear enough to determine more information. Its usually done because the manufacturer was too cheap to use a switch with enough contacts on it to begin with. Cheers, Peter Mar 01, 2013 This works for any mic.
For extra filtering protection, also connect a. Your email address will not be published. Use your Ohmmeter to touch the remaining three colors with both test probes. The cure is cheap and simple. If you can still hear something, its relay switched. Check for breaks or damage to the plug and cord. So, try that and see if you get lucky, if they don't have it, then it could be difficult indeed.
I still have four D-104 microphones including a Bicentennial 18kt Golden Eagle in the original box and packing and paperwork… never wired. These will easily fit inside the mike. I hope you find this useful and best of luck. How To Cure The Squeal Refer to Figure 3. These Mics were made a long time ago and Astatic has a rich history going back to 1933. Now attach a clip-lead or a piece of bare wire to the common pin you found in Step 2.
