[PVRCNC] [PVRC] W3NQN Band Pass Filter kits

[Rob Katz]

Hi Vasily,

Yes, these BPFs are designed for additional isolation beyond what is built
into the radio.  I am going to use them for an SO2R setup.  The W3NQN
filters are reported to be at the top in terms of filter design.

The price is not finalized yet, but it looks like it will be somewhere
around $300 for boards, parts, custom capacitors that are hard to source
here, and a custom designed case.  You can buy any or all of these (for
example, you can buy only the PCBs, all but the case, etc.)  This does not
include the toroids which can be ordered elsewhere for $44, nor the wire for
the coils.  Array Solutions sells a similar design as a finished product for
$975.

73,
   Rob  K4OV
