Yaesu M-90D Desktop Microphones
Yaesu M-90D Desktop Microphones utilize a finely tuned dynamic element to deliver rich low to mid frequency response, desirable for a clear and concise conversational sound that is pleasing to the ear of the listener. The oversize dynamic microphone element and windscreen of the M-90D is designed to accentuate voice input from the front and limit ambient noise and sounds from the side. The attractive desk stand base of the M-90D features a large PTT bar switch, a PTT lock button, and both 8-pin modular and round connectors at the back. By swapping the orientation of the supplied coiled cord cable with 8-pin round and modular connectors at either end, the M-90D may be used with virtually any Yaesu HF transceiver*. For difficult band conditions, a built-in, low-cut filter creates clear and crisp audio characteristics by shaping the low frequency response (cut off at 340Hz, -6dB/octave). An integrated isolation transformer enhances the audio quality of this fine microphone, which also uses three air cylinder tubes, similar to the M-1 Reference Microphone, to provide a lifetime of solid, smooth, and noiseless PTT operation. Yaesu M-90D Desktop Microphone specifications: Microphone type: Dynamic element, preamplified Supply voltage: 5.0 V DC ±10 percent (supplied by most Yaesu transceiver mic connectors*) Frequency response: 30 to 17000 Hz Sensitivity: -60 dB (1 kHz 0 dB=1V/1Pa) Microphone impedance: 600 ohms Dimensions (WHD): 4.17 x 7.56 x 4.98 in. (106 x 192 x 126.5mm) Height maximum when microphone head position is flat Weight: 18.70 oz. (530 g) without cable NOTE: The M-90D Mic head does not disconnect from the desk stand base for other uses. (See M-90MS Mic Head for boom or mic stand applications.) The M-90D is directly compatible with the FTDX101 Series, FTDX10, FT-991A, FT-891, FTDX5000 Series, FTDX3000/D, FTDX1200, FTDX9000 Series, FTDX2000/D, FT-950, FT-450/D, FT-897/D, FT-857/D, FT-818ND, FT-817/ND, FT-900, FT-847, FT-920, FT-1000MP, FT-1000MP MARK-V and FT-1000MP MARK-V Field. *Optional Power Supply Kit ABB19X001 required for M-90D use with Legacy Yaesu FT-1000/D, FT-990, FT-890, FT-840 and FT-747 transceivers.

Heil Sound Pro Set Elite Headsets
Heil Sound Pro Set Elite Headsets are the ultimate boom-mic headsets designed for Amateur Radio operators using the Heil HC 6 wide-response microphone element. The microphone technology of the Heil HC 6 is designed for full-range commercial AM or FM network broadcasts, or it may be adjusted for bright, articulate audio to cut through Amateur Radio noise and signal pileups. Pro Set Elite headsets contain specially-designed high-performance dynamic elements that compliment advanced audio adjustability of modern Amateur Radio transceivers. The -3 dB points are fixed at 80 Hz and 12.5 kHz. Pro Set Elite Headsets offer round, over-the-ear cushioned pads with highly efficient speakers mounted in acoustically-tuned chambers. They seal the ears into their chamber and facilitate a high rejection of outside noise. An exclusive Heil phase-reversal switch allows the user to move the signal acoustically, which creates a spatial widening of the sound field. That makes it easier to 'see' a signal inside of a pileup while helping to remove listener fatigue during prolonged use. The headphone's speakers fold up for easy transportation and storage. Field-replaceable cushioned ear pads also come with cotton covers that can be easily removed for washing. Their 6 ft. coiled cable terminates in a 1/8 in. mono plug for the microphone and a stereo 1/8 in. plug for the headphone speaker connection. A 1/8 in. to 1/4 in. headphone jack adapter is also supplied. Note: Whenever the DX Engineering "Documentation" tab is available, please look at the associated files for additional product information. Pro Set Elite Headsets work with all Heil AD-1 adapter cables, which mate with just about every type of amateur radio transceiver. Purchase an AD-1 series Headset Adapter Cable (sold separately) for a simple connection to the transceiver mic input. The adapter is 6 in. long and has a 1/8 in. female input jack for the headset boom microphone and a 1/4 in. female for the PTT (push to talk) line for the Heil foot or hand switch. The headset stereo plug goes into the headphone jack on the transceiver front panel. You deserve the quality and versatility of superior headsets. Heil Sound Pro Set Elite Headsets from DX Engineering will help you log the rare ones!

Heil Ham Radio BM-17 Lightweight Headsets
The redesigned Heil Ham Radio BM-17 Lightweight Headsets are excellent for portable operations, with several updates including the new swivel-mounted boom that allows operators the flexibility of positioning the microphone on the left or right side. These headsets are available as either the BM-17S single-side or BM-17D dual-side model and are now only available in standard black, with "Heil Ham Radio" brand. To accommodate different transceivers, both models of the BM-17 are available with either a Dynamic element or an iC Electret element. The speakers used in the BM-17 headset are extra sensitive, so they do not require much AF drive from the transceiver. Their frequency response is 200 Hz – 5 kHz with exceptionally low distortion and each features replaceable ear pads made of acoustic foam. Heil Headsets feature two different mic elements, so they must be paired with the appropriate Heil AD-1 series transceiver mic adapter cable (not included). • The BM-17 Dynamic headset uses the dynamic element designed specifically for communications use, with an operating frequency response of 120 Hz – 10 kHz. This 500 ohm dynamic element will work on most amateur radio rigs requiring a Low-Z input impedance (usually between 150 ohms and 4k ohms). Legacy transmitters and transceivers that require a high impedance microphone input of 10k to 30k ohms can be accommodated with a Heil XT-1 impedance matching transformer. • The BM-17 iC Electret element works with virtually all Icom rigs and were specifically made to provide the best audio solution for the low microphone gain audio characteristics of most "pre-PRO" and basic Icom rigs. The iC element has an operating frequency response of 35Hz – 12kHz. The -3 dB points are fixed at 100 Hz and 12 kHz with the sensitivity of -57 at 600 ohms output centered at 1 kHz. The iC element requires + 5 Volts DC bias power to operate. The microphone audio for the BM-17 series terminates into a red 1/8 in. mono plug while the headphone terminates into a black 1/8 in. stereo plug (1/8 to 1/4 in. adapter included). The use of the AD-1 series mic adapters allows simple interface with popular transceiver inputs. The AD-1 series adapters are 6 to 8 in. long and has a 1/8" female input jack for the headset microphone while the 1/4" female that exits the adapter is the PTT (push to talk) line for a Heil foot switch or hand switch. The 1/8" or 1/4" stereo plug goes into the headphone jack on the transceiver front panel. The stainless steel band inside the padded top can be reshaped for a comfortable custom fit. NOTICE: Some state laws prohibit the use of headsets while operating a vehicle. Please check with your local regulations and restrictions prior to usage of this product while operating.
