FT-817 Filter Module SSB/CW

LASERBEAM-817 Audio Filter Module (also works 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

• RAZOR-SHARP SKIRTS CUT OUT QRM
• SUPERB SSB AND CW PERFORMANCE
• IMPROVES PERFORMANCE WITH OR WITHOUT THE OPTIONAL MECHANICAL FILTERS
• TWO GREAT FILTERS FOR LESS THAN HALF THE COST OF A SINGLE MECHANICAL FILTER

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-817/818. 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.

Note that these are bandpass filters only, so will not do anything about noise inside the passband. However, they should be very effective at eliminating noise and signals outside the passband.

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 does require some work to fit, but should be 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.

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 unnoticeable. 

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

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

Can the module be used in the FT-818?

The FT-818 is virtually identical to the FT-817, so yes the module should be compatible and the installation procedure should be very similar.

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 sharper 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!

 What is the purpose of the button on the module?

In older versions of the firmware, if the button is pressed while powering up the module, then it will show the software version by flashing the LED. It has no other purpose in the FT-817 module, so can be removed if you wish.

It should not be held down at power on, as otherwise the module may just keep flashing the LED instead of processing any audio. In later versions of the FT-817 module firmware, button presses are ignored in order to avoid this problem.

***IMPORTANT***

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.
