Notch or Boost. The Heil Sound GM-4/GM-5 microphones, Pro Set 4/5 and similar boom sets, and other such mics using built-in enhancement of treble and roll-off of bass may not need any adjustment on the high-frequency side for local rag-chewing; however, depending on your voice and the degree of fidelity desired, you may want to add some bass response for local work. I used a PROC level of 25 and the mic gain to the 11 o'clock position. Parametric Eq frequency/level/bandwidth settings are; 200/9/5, 1500/5/5, 2700/5/5. With the trend to ever-smaller living spaces RF feedback rears it's ugly head. 'Bandwidth' control set to a wider setting (say 10), the filter will encompass the audio frequencies from about 100 Hz to 400 Hz. The K3 also has provision for direct connection of the mic cable from a Heil Sound headset, with no adapter required (! The 7300 is a terrific value. As mentioned above, be sure the main switch of the MD-100 is set to THRU to bypass any in mic settings and to use only the rig's settings. DSP Setting Example: Yaesu FT-920. Transmitter IMD specifications on most amateur transceivers were never all that great. A Parametric EQ is just as the term implies. Now set the transmit bandwidth (either with compression on or off) to Wide, and transmit while you listen to yourself in the monitor receiver. Menu 091 Frequency DSP and Carrier Point SettingsYaesu has, since the 1980s, provided means for adjusting the carrier insertion point (identical to IF SHIFT used on receive, only this is on your transmitted signal). Try moving Menu 102 to 300, Menu 119 to 300 HZ, Menu 128 to 300. IMHO, it is a good idea for hams to have some sort of quality monitoring setup as part of their shack. Of course, the voice signal is AC, so DC flows one direction while AC flows the other direction all on the same cable. Flex and Apache units do very well or a real spectrum analyzer. Last, Heil's cables contain a small jumper wire from mic shield pin of the connector to the shell of the mic. The table that follows details starting points for operation using two main categories of mics: the articulated elements (HC-6, HC -7 and HC-5.1 based mics), and the wide range elements, typified by the iCM, Handi Mic iC, PR 781 and the PR 20/30/40 genre. Then select multiple frequencies between 10 and 5000 Hz to get enough data to plot the filter shape on graph paper [frequency verses power output]. As for the suggestion of a 1000 Hz boost, seeing how male voices center around 500 Hz and females around 700 Hz, there's little to be gained there. This will keep the DC factor into the mic preamp circuitry. Mic gain: 30. Suddenly, there were just 3 pots! Sign In Upload. "Yaesu has recently had several reports that the 950 is VERY sensitive to RF. By Dave De Coons, WO2X wo2x@arrl.net Yaesu FT-2000 Set the radio menu's for the following settings: Menu Value 85 1-30 125 100 126 2 127 1 . The first thing to set is the frequency that you need to affect. Setting Up The YAESU FT-950 TX EQ - eHam.net The same button turns the Compression On or Off also is used to adjust the Transmit Bandwidth Filter. Set the TX BW to 400 -2600Hz for DX/Contest work. Since I can't actually HEAR your transmitted signal, these are just starting points. The coupling capacitor is NOT installed in our new high-impedance GM VINTAGE microphone, as this model should never be used with ICOM low impedance inputs. Borrowing technology from the recording studios, DC power is applied via the mic line to energize the electret elements used in stock Icom microphones. Great piece here! 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. This will roll off some of the extreme low frequency response. Looking for "Parametric" Equalizer and "P Parametric" Equalizer settings for my Heil Proset 6 headset with the HC-6 element. Also, you dont have the benefit of hearing all the net effects of AGC, etc., like other stations receivers, are employing. There is no "perfect" setting, it's all subjective. Then, 'plot the spectrum. In my case I've added the reference point that I started out from and with some adjustments in the processor I'm at a point where I'm happy and get good reports. That should move your bass setting up 100hz. In the menu go to Radio Settings. Yaesu ftdx1200 EQ settings & W2IHY. Do you have a wide range studio or broadcast microphone, or perhaps one of Heil Sounds high-articulation microphones using the HC-4 or HC-5 elements? 8 Band EQ settings for the Yaesu FTX9000. HF/50 MHZ TRANSCEIVER. Why not just buy a Goldline series mic and use a GM5 element and save a ton of money? All ICOM transceivers utilize phantom power on their microphone inputs. And then someone tells you, 'You have RF on your audio', and you start checking everything over again! Boost it with that adjustment but it is best to reduce (notch) that low end a bit for cleaner and clearer audio. Interesting and well written article. You will perhaps want to change the frequencies of the first two filters if you are using an HC 4 or HC 5 element which is much narrower in response than the above microphones but start hear and see how this affects your transmitted signal. Edit: Yaesu MD-100: Main->Filt, High emphasis->on, low cut->off. You may get by with a .68 F or a .47 uF, but anything less (.01 F, .005 F, etc.) I run the gain at 12 o clock, and the switch on the back of the mic to the right when looking at the back of the mic. In other words, the lower number seems to have a lower Q, so the filter affects more frequencies. To increase high-frequency articulation, without rolling off lows or mid-range, use selection 4.See page 81 of the Operating Manual for details. You only have control to either cut or boost the filter frequency they build into the transmitter. Set EQ3 Frequency to 2100 Hz, EQ2 Level to +10, and EQ3 Bandwidth to 2. Already in the battery box is a load resistor & 1 uF capacitor.The headset can be plugged directly into your PC without the battery box. DSP Setting Example: Yaesu FT-950/2000 and FTdx9000 Series. Oftentimes OFF is best.Menu 8-9: Generally, you dont need to touch this one. Also go out buy yourself a Audio Technica ATR-30 for 18 bucks on amazon. Sad. To build the largest and most complete Amateur Radio community site on the Internet - a "portal" that hams think of as the first place to go for information, to exchange ideas, and be part of whats happening with ham radio on the Internet. There are too many external path things which can botch up your signal, and those issues can't be corrected on your end. Do you want some big boomy low end? With my Heil GM-5 I has the mic gain on the FT-950 set at 14 percent. Or leave it off. eHam.net provides recognition and enjoyment to the people who use, contribute, and build the site. Press the (PROC) button momentarily so MIC EQ shows up on the display. Again, these are necessary starting points for operation, and it should be noted that, when using the HC-6, HC-7, and HC-5.1 elements, the equalizer may be left at its default setting of 0 across the board, since equalization is already taking place in the mic element itself. If you try to use the AD-1-iC or AD-1-iCM 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. Voices are like snowflakes, no two are alike. You will want to listen to your signal in a second receiver and make small minor adjustments to tailor the audio you desire.The receiver also has a great equalization circuit so adjust the treble and bass to your listening preference. Sounds terrible on the product detector as well. The iCOM 7300 has been updated to work with all Heil Sound iCM. You then set the Bandwidth of that filter and finally you tell the filter if is notches (cuts, reduces) or boosts that filter frequency. Again YOU have to make the final decision by listening to your own signal. If you have more than three frequencies which need attention you have more problems than an equalizer is going to fix! You then know exactly how you sound to the outside world. You simply select the needed frequency, boost or notch that frequency and set the bandwidth as to how wide you need to affect. All of my Icom friends got the same headset when they tried mine! Several Kenwood rigs have DSP and other settings that will allow the operator to adjust the response of the radio to your speech input from the microphone. You set the frequency of the filter. See the FTDX10 FUNC > OPERATION SETTINGS > TX AUDIO settings. Welcome to Yaesu.com You want to boost that frequency, you adjust it to + 10dB. One for processor off and one for processor on. The supplied hand microphone as ALL hand mics, sounds hollow and mushy. Kenwood rigs present relatively few problems in interfacing to Heil products. This HAS to be shown as it turns the parametric EQ on. This voltage must be blocked for use of Heil Sound dynamic elements. We have notched some low end out by setting the transmit bandwidth in the beginning then with the EQ, we reduced some low end (menu 091) and this is always a major problem. There are certainly many other methods of setting up the mic and processor, but I learned a lot by doing it this way. The iC element also works tremendously well with the modern types of Icom rigs, making it an ideal all-around microphone. Big enough that it could also cut the second filter, even with a Q of 5. I personally LOVE audacity for QC and monitoring purposes. Now we move onto the Parametric. PDF Yaesu Parametric EQ - K9ROD Bandwidth of 5 Menu 093 Bandwidth These rigs use a three-band parametric equalizer system. Set the TX Equalizer to 2 for local rag-chews, 9 for DX work (1 is also good), and use the 4 setting when using mics with the HC-4 element. There is usually some craziness that happens around 400 Hz. We highly suggest our dynamic element microphones (HC-7, HC-5.1 , HC-6, Goldline GM series or PR-781 type). Problem solved. Once you get the Wide bandwidth set, press and hold in the COMP key to try the MID bandwidth, then the NAR bandwidth. I don't particularly care for using the hand held mike and have ordered an MD-100a8x so these settings might help with that mic, but as my grandfather always said, if it ain't broke, don't fix it, so I will be leaving the EQ and Processing off until I need to refer to this article for setting up the EQ when I get complaints instead of compliments on my audio.
