After installation, Menu #38 is set to CW (and never needs to be
changed again). You never have to select the SSB filter because it is
always in the circuit anytime the former MuRata filter was selected.
To select the CW filter, you simply press the NAR Key (Function Row
7, Key C) when desired (and you are in a valid Mode).
The One-Board Filter is now available for installation by FT-817
owners that have adequate skill and equipment to work with SMT
components. The One-Board Filter can also be installed by W4RT
Electronics, which requires that you ship your FT-817 to W4RT
Electronics. The installation will take place and the radio will be
shipped typically within one business day of receipt of your FT-817.
As you likely know, the suggested retail price of the Yaesu CW and
SSB filters are each $170 and the equivalent filters from
International Radio (INRAD) are $125 and $145, respectively. The
One-Board Filter for W4RT Electronics is priced at $269 installed and
$239 for user installed. Frankly, this is a rather good value.
· Who is responsible for packing, insuring, and shipping the
radio to W4RT Electronics? The radio's owner. You are encouraged
to pack the radio very well and to insure it appropriately. A
tracking number is also strongly suggested. Use good quality shipping
materials. (The original factory carton packed in a strong outer box
· Should the radio be shipped with the batteries or battery
pack installed? No, unless it is the W4RT OPP.
· Should the radio be shipped with the Optional Yaesu or
INRAD filter installed? It is okay to leave it installed.
· How is the radio shipped back after the OBF installation?
The return shipment will be by UPS Ground and insured for $1000. (US only.)
· Is shipping included in the price? No. The charge will
be $12.50. (US only.)
· Will I know when my radio is shipped? Yes, you will be
emailed the date of shipment and the tracking number.
· Do I just send my radio after I place the order for the OBF?
No, please wait till we notify you we would like to receive your
radio. Typically, there is no delay. Our intent is to have your radio
away from you the minimal time practicable.
· I don't live in the USA. Can I still have the OBF installed
in my radio? Best to purchase the user installed version of the
OBF. Some non-US hams had the installation performed during their
visit to the US. W4RT Electronics will attempt to work with you.
· Does the OBF interfere with the installation of the
optional TCXO? No.
· I have the FT-817ND. Does the OBF install the same as in
the FT-817? Maybe, but some of the FT-817ND units have two
very-small SMT resistors placed in the filter circuit where SMT
capacitors were used before. If your FT-817ND has the resistors, they
need to be preplaced with the proper capacitors. This requires proper
SMT skill and equipment. If you don't have both, then we strongly
urge you to have W4RT Electronics perform the installation for you.
Please see the manual.
· Does the SSB filter really improve the performance of the
FT-817 on SSB? Yes, in our opinion. This is based upon both
laboratory and on-the-air tests. The passband is much better defined
and is very flat. Talk power and speech clarity are improved. On
receive, you will not hear significant improvement with the built-in
speaker; however, if you use a higher quality speaker or good
headphones, the difference will be obvious.
· Does the OBF affect the use of an external DSP like the
HEAR IT, bhi, or ClearSpeech units? No, except that the results
will likely be better due to the higher quality audio from the receiver.
· Are there any adjustment to the OBF? No and yes. There
are none on the OBF, but the FT-817 does provide the control of the
carrier insertion point on both transmit and receive (see Menu
#54-57). These can be adjusted for your voice characteristics (to
maximize talk power) and best listening.
· I already own the Yaesu or INRAD CW
and/or SSB filter(s). What do I do with it (them)?
We suggest that you try to sell it (them) to a friend, on eHam.com,
QRZ.com, eBay.com, etc. Alternatively, we will accept your filter,
test it, remove it from its mounting, and use it in your OBF. You
will be given a $50 credit for each filter. Contact W4RT for details.
· Can I have a 300-Hz Collins Mechanical Filter? Yes you
can. The 300 Hz is generally selected by those working contests and
PSK. For PSK, the 300 Hz and the 2300 Hz are a good pair since the
transmit uses the 2300 Hz filter. The stock filter rolls off from
center frequency and means you decrease ouput power as you operate
away from the band center. The Collins 2300 Hz fillter is very flat
and resolves the aforementioned problem.
· Why is the business called W4RT Electronics? Simple.
W4RT is the call sign of our club station (Tornado Amateur Radio
Club) in the parent company, the PanTechne Corporation.
· Is W4RT Electronics now or has it ever been a part of RT Systems? No.
· Can I call you on the telephone to discuss the OBF? No.
We don't have an incoming customer telephone line. Please send
question by email or fax. They are handled quickly.
Thank you for your interest in W4RT Electronics products; the entire
W4RT Electronics Team sincerely appreciates your support. We are
confident that you will find the OBF to be an outstanding addition to
the FT-817 that will enhance your operating enjoyment for years to come.
