[Yaesu] FT-817 DIY Dual-Filter Installation

[Barry Johnson]

For almost four years, W4RT Electronics has been installing the One-Board 
Filter (OBF) in the FT-817 which allows FT-817 owners to enjoy having both 
the CW and SSB Collins Mechanical Filters.  The OBF utilizes Collins 
Mechanical Filters that are the same as used in the optional Yaesu filters 
for the FT-817. The bandwidth of the 7-pole CW filter is 500 Hz and the 
10-pole SSB filter is 2.3 kHz. See eHam.com reviews at 
http://www.eham.net/reviews/detail/1784.

The One-Board Filter has NOT been available for installation by FT-817 
owners until NOW as a "do-it-yourself" option.  For those that want the 
One-Board Filter installed by W4RT Electronics, that option remains 
available.  In other words, both DIY and W4RT installed versions are 
available.  This is especially important to hams not located in the USA 
since the shipping issues are significant.

Installation is not trivial, so you should be confident that you have the 
skills, tools (SMT level), and experience needed to do the job correctly. 
Please read the OBF Instruction Manual (on the W4RT web site or at 
http://www.w4rt.com/obf/OBF_FT-817_Manual.pdf) BEFORE ordering to 
understand  what is involved and the terms.  The total difference in price 
of DIY and W4RT installed is about $50.  No technical assistance is 
provided if you DIY, so be sure before you attempt an installation.

DIY price is $239 + S&H.  W4RT installed is $269 + S&H and turnaround is 
almost always just one business day.

The One-Board Filter for DIY is available now and will be at Dayton too.
