LASERBEAM-817 Audio Filter Module (not tested in the FT-818)

"This Laserbeam digital audio filter has turned my FT-817 into the CW transceiver I was hoping for when I bought the rig" Peter - W2BEW. June 2016

***Fitter for hire in the UK!***


Building on the success of our range of LASERBEAM Filter Modules, the LASERBEAM-817 digital audio filter module is the perfect addition to your FT-817. Unlike analogue filters, digital filters provide near-perfect characteristics. Because of the way that the filters are implemented, they are better than analogue filters in almost every way!

The LASERBEAM-817 Module has been designed to specifically compliment the FT-817. It has a new filter line-up, optimised gain for this application, revised switching and a filter select LED. The LASERBEAM-817 greatly improves on the performance of the stock ceramic SSB filter and has a far superior shape-factor when compared to the aftermarket Collins Mechanical Filters. The LASERBEAM-817 module is an amazing value upgrade whether you have extra filters installed or not.

The LASERBEAM-817 Module has two superb digital filters: a 300-2700Hz SSB filter and a 450-950Hz (500Hz) CW filter. These filters have been specifically optimised for the FT-817. The filter switching is fully automatic - no external switches required.

Each LASERBEAM-817 Module is supplied with a special integration kit which includes the main parts that you will need to complete your installation.

Installing your LASERBEAM-817 module

The LASERBEAM-817 module is easy to fit - no harder than installing an after-market noise reduction unit. We provide detailed instructions that can be downloaded by clicking here.We recommend reading the instructions before purchase. Last update 11-May-16.

What are the advantages and disadvantages of a LASERBEAM-817 module compared to fitting a normal CW filter?

The LASERBEAM-817 modules provide near perfect filter characteristics - far better than a crystal/mechanical filter. They also work on both CW and SSB. They are far cheaper than crystal/mechanical filters.

LASERBEAM-817 filters are more complex to install than plug-in filters. They do not sit within the IF AGC loop of the radio, so in some circumstances you may need to use your FT-817's RF gain control to get the best results. All DSP filtering introduces a low level of white noise. This is typically more than 60dB down on the wanted audio and is generally unnoticable. 

What models of the FT-817 can the module be used in?

The LASERBEAM-817 works with all known models of the FT-817. 

I have the optional narrow SSB filter in my FT-817. Can I use a LASERBEAM-817 to add a narrow CW filter?

Yes you can do this. The LASERBEAM-817 is a better filter than the Yaesu YF-122S filter so we recommend setting Menu #38 (OP FILTER) to "CW" which will mean you have the benefit of better SSB filtering all the time with the added bonus that you now have a CW filter too.

 I have the optional CW filter in my FT-817. Will a LASERBEAM-817 make any difference?

Yes: a LASERBEAM-817 will make a big difference. The optional filters for the FT-817 have very poor skirt selectivity. The LASERBEAM-817 will improve both CW and SSB performance. The difference has to be heard to be believed!

 Is the LASERBEAM-817 filter the same as a noise reduction module?

After-market noise reduction systems reduce noise in the passband of the radio and are primarily effective on phone modes only (SSB/FM). The LASERBEAM-817 is effective on both phone and CW modes and removes unwanted signal that are outside the passband of the filters. Both systems have value - but they are different.

I have an aftermarket noise reduction unit installed in my FT-817. Can I also install a LASERBEAM-817 Filter?

It is unlikely that you can install a LASERBEAM-817 if you have a noise-reduction unit installed.

 Can I save some money and install your General Purpose Filter Module in my FT-817?

The software on the LASERBEAM-817 has been designed specifically to complement the FT-817 and make the installation simple with automatic switching. Our General Purpose Module has different filters and different switching.

 Does the LASERBEAM-817 Module have any other effect on the FT-817?

The LASERBEAM-817 filter is always in circuit - on all bands and in all modes. For example, on the broadcast VHF FM band (WFM) the audio frequency range will be limited by the module, the same will apply to the "DIG" mode or FM.

 Will you be producing other versions of the LASERBEAM-817 with different filters?

We have no current plans to produce additional versions for the FT-817. This could change is there is sufficient demand for another combination of filters (wide and narrow SSB for example). Let us know!

 Can I use a LASERBEAM-817 Module in my FT-857D/FT-897D?

The FT-857D/FT-897D radios already have DSP filtering so there is unlikely to be much to be gained by installing a LASERBEAM-817 Module. Please refer to the user manual for your radio for details. The module may be suitable for fitting in older "non-DSP" versions of this radio but we do not directly support this type of installation. If you do it successfully, let us know!


LASERBEAM Module Specification

Typical supply current: 30 mA @ 12 Volts

Filter type: Multi-tap FIR

Module size: 36 x 36 mm (approx 1.4 x 1.4 inches) Fits inside your FT-817

Weight: 5.5 grams

Ultimate rejection: better than 60 dB

Passband ripple: <0.15 dB

Installing a LASERBEAM-817 Filter may invalidate the warranty of your radio.

Experience and skill in working with with surface mount components (SMDs) is desirable.

Installed at owners' risk! This is not a "plug in" unit and requires similar skills to installing the various after-market Noise Reduction systems that are available for the FT-817.

    I'm > REALLY < happy !!

    Posted by Adriano on 22nd May 2016

    Hello, please let me say something about this "bit of kit" . The performances on CW raise at top and i really doubt You will get anything better. Not with the "common" mechanical filter nor with "the other brand", from US. The SSB also IS greatly improved and I just can't believe to my ears, honest. Please keep in mind that i don't have any businnes with Sotabeams so if i had to say "bad things" ...but this NOT the case. The installation gone fine even if i never had to put my hands on that tiny SMD technology. Just follow the CLEAR instructons, get relaxed and you won't fail. Last but not least i"had" to ask something and Richard answered even if Sat evening - Sun morning. Two GREAT filters at HALF cost of just one. A GREAT PRODUCT , for (very) little money.

    A really great addition to this little rig.

    Posted by Anthony Enright on 17th May 2016

    Fitting this module is not for the faint hearted as mentioned in the instructions if you are not comfortable with Surface Mount components then get it fitted by someone who is. It took me about an hour or so to fit with the aid of a very fine tipped soldering iron and a pair of magnifying specs. The removal of one Surface Mount capacitor is probably the most difficult task but I had a suitable de-soldering bit for my iron which made its removal simple.

    If you follow the instructions to the letter you won't encounter any problems though great care is needed refitting the PCB to the unit so as to not damage the inter connecting pins on the main unit. I did replace the speaker with an RS unit Part Number 719-1964 which enables you to refit everything using original fittings. This speaker is only 7mm thick and poses no interference to the new module and sound as good as the original.

    The filter does exactly what it should and is really terrific especially on CW very sharp indeed. I am really delighted with the performance and am so pleased I didn't spend a lot more on a mechanical filter.

    Well Done SotaBeams. Tony EI6DT

    FT817: significant audio improvement

    Posted by Roger G7RUH on 30th Apr 2016

    Installed the kit in an 817ND without extra filters, SSB audio greatly improved. Much less hiss which used to be very wearing on the ears. Voice sounds richer and has improved clarity. CW filter is sharp and clean.

    Instructions are clear and the modifications are easy as long as you have some surface mount experience. If you are not sure, ask someone to fit it for you, it is worth the expense and effort.

    Very good value for money and works as described on the SOTABEAMS web site.

    The FT 817 has needed a low cost SSB filter for a long time and this one does CW too, thanks SOTABEAMS.
