Stations all over the world have asked him what he is using to sound so good. Our thanks to N4FZ for making this recording. Notice the dramatic improvement in signal to noise talk power when the EQplus compressor is activated. Listen to the fascinating procedure and the stunning results. If a picture is worth a thousand words, these recordings are worth a thousand pictures. Please take a few moments to listen to these awesome audio demonstrations.

Good deal! Un-smug-a-licious Contributing Member Offline Posts: JavaScript seems to be disabled in your browser. As Ralph points, this info has been floating around for almost 30 years. Moderator Member Offline Posts: Nothing new. Most icoms are horrible on AM and really yank the power back if you try to run any audio at all. My FTD does pull back a bit but carefull setting of the knobs and you do not need it. My FT for example does not do this so its not needed. It should work on any solid state transciever that pulls back the carrier when modulated on AM. I have been here a few years and cant remember it.

Just curious, didn't that mod box also apply to the Kenwood TS as well? It may have been posted here. Pretty cool little project and no need to open radio up. Now you can turn up your audio and the radio never pulls back the power. Then adjust the carrier using the pot on your new alc box. I slapped resistor across the pot to lower it to K. We used cheap radio shack plastic project boxes and 1 meg pots. A friend came over and we built two of these ALC boxes.

This is pretty cool until you start having RFI problems, but we shall ignore that possibility for now.April 10,PM Welcome, Guest. Of course, the voice signal is AC, so DC flows one direction while AC flows the other direction - all on the same cable. The receiver also has a great equalization circuit so adjust the treble and bass to your listening preference.īorrowing technology from the recording studios, DC power is applied via the mic line to energize the electret elements used in stock Icom microphones. You will want to listen to your signal in a second receiver and make small minor adjustments to tailor the audio you desire. The PRO 7-iC has the appropriate cable included and will sound wonderful with a Usual mic gain will be set between 65 to Pay attention to the ALC.

Great receiver, full coverage through 6 meters.
Truly a game changer in the amateur radio transceiver market. Just contact your dealer to get the HSTA Adapter Cable, and the Traveler should work perfectly using the factory default settings on the rig. Set the Transmit Bandwidth to Wide Hzand you will be the talk of the band! The iCM is the perfect match for the iC Set the microphone gain to 70 and with the stock bandwidth of 2. The supplied hand microphone - as ALL hand mics, sounds hollow and mushy. Always adjust mic gain by watching the ALC meter. Monitoring of your signal is particularly important when setting Menu item Q4, which has a huge effect on your transmitted tonal quality. When using a dynamic element on rigs like iCOMS, which were designed for electret microphone elements, one must not be afraid to do two things: 1 utilize the full range of Mic Gain available, and 2 turn on the Compression, using the Compression Level control as a secondary Mic Gain control if necessary. Click here to view pinout information for hundreds of rigs, mics, and connectors. This voltage must be blocked for use of Heil Sound dynamic elements. Heil Sound recently introduced the model PR dynamic microphone, which sounds simply wonderful on modern Icoms. Diagram based 2007 cobalt stereo wiring diagram If you try to use the ADiC or ADiCM adapter cable on a dynamic-element microphone, the lack of a blocking capacitor will cause the element to seize up, and no output will be heard.
The ADI and ADIM include blocking capacitors that prevent the phantom power supplied by the radio from affecting the performance of the dynamic elements. These had no microphone preamplifier, it was built into the microphone. For more on the iCOM settings, see below.
