Hi all,

PA3AKE, has just updated his website.

Please look at the following:

in particular the release of the front-end board with
additional 500Hz CW roofing filter. This update is

Thanks Gian. It might be of interest to people in Europe who homebrew as
well as buy rigs that contrary to popular wisdom and based on 'on air' use,
the high IMDDR3 at 1 kHz spacing of Martein's front end and roofing filter
is worth having when working SSB DX zero beat with or among the 40m BC
stations. To date AM BC transmitter phase noise does not appear to be a
limiting factor, their modulation can be sometimes.

73,
