These instructions will explain how install BHI NEDSP1901-KBD module to Icom IC-736 / 738 tranceiver:

  • Remove both upside and bottom cover.
  • Turn radio upside down so that bottom side is up and front panel is toward to you.
  • Detach four coaxial cable, two coming PLL unit and two is near backpanel.
  • Detach white ribbon cable coming from front panel.
  • Unscrew all main unit screws ( 8 pcs ) and one what hold regulator near front panel.
  • Locate C217 which is placed between notch board and larger metal shield.
  • Pull main unit from chassiss and turn solder side up so that you can remoce C217.
  • Find thin audio cable ie. PC CD ROM audio cable and solder it point wher C217 was.
  • Round point on C217 marks audio from preamp ( audio to DSP module).
  • Reassembly main unit. Screws and cables.
  • Solder red wire to regulator (which is near front panel) right side leg. That is +8VDC to DSP module.
  • Now, turn radio “right” side.
  • Find appropriate place where install DSP main unit.
  • Because original cables is actually too short, you have to remove those audio and supply wires longer. Use desolder sucking wick or other and remove audio and supply wires from DSP module.
  • Check where you install DSP module and cut those wires proper lenght.
  • Solder wires to DSP module and check that audio wires is correct way.
  • Original supply wire has protect diode but if you are sure that you connect plus wire right it can be removed.
  • Install ground connections where is best place.
  • Check that all is ok and connect power supply and antenna to the radio.
  • Now you can refer BHI NEDSP1901-KBD manual to set proper audio levels.
  • When all set you can now test how it works and if it works thats fine.
  • Remove radio connections and find place where install DSP unit and check if you have to put longer wires to the keyboard/LED board. (I have to make so).
  • Measure upper cover where you can install keyboard/LED unit. Dont forget radio signal meter place on inside. Few mm. From s-meter is plenty place to attach this unit.
  • Next, measure from front panel how far it keyboard unit can placed. It might be 14-15mm on upper cover front side. Then measure keyboard and LED hole and drill approriate holes.

I glue keyboard/LED unit to upper cover a hot glue. This DSP module can install any radio if you have schematic diagram and can find right place in radio. I no take any liability for this modification. You take you own risk. And if your radio have guarantee, any modification or so. Cancel guarantees. If you don't know what you are doing, don't do any.

Our noise cancelling products for amateur radio enthusiasts

ParaPro EQ20-DSP noise cancelling unit with 20W audio and parametric equalisation

The ParaPro EQ20-DSP is an invaluable tool for ham radio operators. Its high-powered 20W dual channel amplifier provides plenty of clean audio for base station speakers, while the parametric equaliser lets you customise the audio to match your hearing and room acoustics. This level of customisable sound shaping isn't found in regular radios. But what makes the ParaPro EQ20-DSP truly special for hams is its adaptive DSP noise reduction technology. The advanced digital filtering can wipe out up to 40dB of ambient background noise and interference that typically interferes with transmissions. It automatically cleans up signals in real-time for noticeably clearer conversations.

Tips for selecting the right noise reduction products

With advanced noise elimination technology, clear amateur radio calls are finally possible even in extreme noise environments. But with various products available, how do you choose what’s right for your specific radio and needs?

The type of setup you have should guide your selection. For example, if you primarily use an extension speaker and/or headphones connected to your radio then one of our In-Line modules would be more suitable.

If you just listen to the radio via its own internal speaker then one of our standalone amplified DSP noise cancelling speakers would work well.

Also consider your audio setup. The ParaPro EQ20-DSP stands out for amateur radio enthusiasts needing amplification to drive larger speakers or headphones while sculpting tones to match hearing loss profiles. Its high power handling equips it for big rooms. For field or mobile setups using handheld transceivers, compact inline devices shine.

Determining the root of your noise woes and matching that with the right product features ensures the best fit. And don’t hesitate to discuss your radio activities with us to dial in the perfect noise-free solution.
