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.

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!
What is the purpose of the button on the module?
In some 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 revisions of the FT-817 module firmware, button presses are ignored in order to avoid this problem.

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.

Although not complex, this is not a modification for a beginner ! I found the instructions very clear. Adding a table with all reference voltages at pt. 21 would be my suggestion. I my case Off: 6,6V; SSB 60mV and CW 6,6V. In operation CW signals are enhanced the most. I find the SSB filter too narrow, it certainly works, but is a bit uncomfy to listen to for long periods.
My ssb and cw reception has now improved dramatically, fitting was straight forward although you need to use a fine tipped iron and fine solder . Just remember to enable the narrow filter in both menus.
I installed one of these filters in a FT-817ND that I have had for a few years and it has, quite simply, transformed the receiver. The SSB performance has become exactly what the radio should have been from the beginning! Installing the kit was pretty straightforward but I can see that someone without enough experience of working with modern small electronics could find it daunting and possibly difficult. Basically, this is a superb unit for any 817 and transforms the performance of the receiver.
Be kind with yourself, drop that thing in your FT-817. It's cheap, easily installed and work like a charm. You will be wondering why you didn't installed it earlier. 73's François
Assembly into the FT-817 was easy, most complicated for me was the refitting of the speaker. The most easy way is to lay the speaker on the main board, close to the Laserbeam, fitting it into the lowest spot. Then take measures of the center of the speaker from front of 817 and from side. Use the measurements to mark a cross on the inside of the lid. Place the speaker and fix it either with tape. Now it should fit snugly. The two screws which held the loudspeaker bracket before can be secured with hot glue from underneath the lid. So they stay in place without bracket and cover the holes as before. The supplied red wire was about 2cm short, but I still had a longer one in the shack. The kit works like a charm. I measured a bandwith for Cw ~ 600 Hertz, SSB ~ 2,3kHz. vy 73, Matthias DF2OF
What an excellent filter very impressed it has turned my 817 into the radio it should have been in the first place, it's a shame it's not in the AGC line. The instructions are clear and took my about an hour to complete. Looking on my spectrum analyser the bandwidths are spot on and very sharp. It's the best digital band pass filter I've heard there is none of the ' water dripping ' or distortion and for its price it can't be beat. The only drawback for me is the data output line isn't going through the filter, so the AFSK modes will have to go out of the headphone socket, but it's handy to see the comparison of the filter for testing. Thank you Sotabeam for an excellent product..73 Chris Cherry 2E0BUJ
Well, the Laserbeam 817 is a real good upgrade for the FT-817, I had no CW filter installed so I wonder how this kit would do the job and I was very impressed from the result in CW, it´s like you have an CW filter installed, even in SSB, the signals are sharper than before. I can recommend this Laserbeam unit for FT-817.
I don't own a KX3; but a friend came round and we made a comparison test with his KX3 and my filter fitted old FT-817ND. Not much between them - apart from the fact that the old Yaesu really, really did sound better on its internal speaker - (I've done the Mylar/Massoth mod) than the KX3! And costs so much less; and is so dented; and still works! Steve, M0HET was a real wonder at fitting the filter; a turnabout of hours!!!! He is to be commended - first class! This is a real winner - I'm not a CW fan out on SOTA; so this is one mod I would heartily recommend to all FT-817 owners! 73.
I took the plunge and installed this filter myself. After some initial trouble after I accidentally stripped one of the PCB pads on C1338 (audio in) I was able to recover by simply soldering a separate piece of shielded cable to a nearby via. Richard supplies more than enough of this cable in the kit to correct any mistakes during the installation. After taking it out for an activation of Mt. MacKenzie (VE7/CP-073) today I can say that the difference is very noticeable and makes operating much easier, especially in busy parts of the band. Terrific performance improvements at a very reasonable price!
The difference the filter made was immediately apparent. Very quiet, highly recommended!
