[UK-CONTEST] Band-switched W3NQN transmitting Band Pass Filters

[Bob Henderson]

A post I made earlier in the year led to the establishment of a very 
successful project (TXBPF) geared to building high performance 
multi-band transmitting band pass filters based upon the W3NQN designs.

The project was geared to the professional production of a six filter 
motherboard and separate filter PCBs.  To date I have completed four six 
band sets for P3F and a further 35 sets are under construction by other 
participating group members.

As a contingency against transit loss or damage, I personally invested 
in a few additional sets of PCBs.  We have now arrived at a point where 
all group members have received their PCB kits without either loss or 
damage.  Consequently those few remaining PCB kits can be made available 
to other interested parties.  A photograph of a completed remote 
switched six band filter set, together with details and performance 
plots can be found at www.5b4agn.net.  Just follow the link on the home 
page.

Custom made cases may be available along with guidance and help with 
parts procurement and build.  Anyone interested is invited to contact me 
directly for further details.
