Re: [drakelist] Drake Twins On CW
Garey Barrell <[EMAIL PROTECTED]> made an utterance to the drakelist gang -- Eddy - The mic amplifier came about primarily because of the solid-state transmitter. The D-104 and other similar mic's were designed to drive very high input impedance (i.e., tube) mic amplifiers, typically 500 k ohms. These mics generated several volts of audio at these impedance levels with no additional amplification. Solid state amps, on the other hand, had input impedances of 500 ohms or so, and these mics were unable to drive them. So some mic manufacturers installed amplifiers, not so much for gain, but to allow them to drive low impedance loads. A secondary effect was that the "bare" mic's frequency response was highly dependent upon the actual load impedance, and of course the internal amplifier was able to reflect an "ideal" load for the mic element. So the amplifier was a good solution all around. The gain control allowed the amplified mic to drive BOTH the low impedance radios at the relatively low level needed (typically hundreds of millivolts) AND the high impedance radios at the high level needed (typically a volt or more) simply by adjusting the gain. The constant input impedance of the internal preamp allowed the mic element itself to have a constant frequency response regardless of the radio it was connected to. You can either use the amplifier or not, as long as you adjust the preamp control correctly. Bypassing the preamp completely is one option, and the input impedance of the T-4X results in a good frequency response from the D-104. Depending upon your voice characteristics, you might want to add a resistor in series with the mic input to tailor the response somewhat. If you leave the preamp in place, you can set the mic gain appropriately by setting the GAIN control on the T-4X to about 10-11 o'clock, and then adjusting the preamp control so that normal speech kicks the Plate meter to about 100 - 150 mA on peaks. 73, Garey - K4OAH Glen Allen, VA Drake 2-B, 4-B, C-Line & TR-4/C Service Supplement CDs Hi Dan, Sounds like "...sound advice" (pun intended!) to me...

The D 104 I use currently works well with the 4 C line and the TR-7. Like the other guys, I rewired the mic and bypassed the preamp in the base of the stand. The reports are usually better than the Shure 444. 73 de W4DL Mike ex AK7P * WA9SWF * WN9SWF

This was also a trend in the commercial radio market. I'm not sure why they went that way, but perhaps because it made dynamic mics interchangable with electret. There's also the possibility that they did it because it's easier to keep induced noise out of the mic cord when the mic circuit is run at a higher lever. I've got some old GE Phoenix radios that have a dual input, pre-amped and non-preamped. >The CB version was that "power mics" were good and the louder you were >the, uh, louder you were. This was not a completely untrue thought. Good >modulation is, . . . good, but easily abused. CB ops tend to like to keep the mic sitting on the table and just reach over and push the button. Of course, this creates a signal-to-noise ratio issue. You could always tell what they were watching on TV, how many dogs they had, whether or not the wife and kids were home, etc. You were a big dog if people could hear your click-click rotor box turning while your were talking. The effect is even worse with compressor mics like some of the Turner models. And then, there's the concept of "swing" - turn the mic up and get more "swing" - the more the better, right? Splatter?

Let us know how it works out, Eddy. Amplified microphones became popular in the late 70's and early 80's, concurrent with, and perhaps because of the "CB Craze": The amateur radio version of all this was that some of the "ricebox" rigs, needed higher audio input to operate . They started using preamplifiers at the microphone input to get it. Some did it by putting the preamp in the microphone (Icom) others put it in the rig. The CB version was that "power mics" were good and the louder you were the, uh, louder you were. This was not a completely untrue thought. Good modulation is, . . . good, but easily abused. In any event, the Drake transmitters (and probably transceivers, but I've never use one) responded well to some of the then current microphones, including the unamplified Astatic D-104's. That's what I use on my T4XB, with good results. I use a Heil 781 microphone through a Behringer 802 preamp/mixer.eq on my Icom 740 to get an equivalent result. Clearly Drake had a better idea!
