[1000mp] 4 kHz roofing filter

[Mihail Mateescu]

Very interesting news concerning the new Inrad roofing filter. I will
certainly install one in my Field, however I don't see it advertised on
Inrad web site. There is a problem though: in case the first LO is not
shifted when changing modes (and why would it with a 12 kHz roofing?) then
one must also give up 2.4 kHz SSB in addition to FM and wideband AM. No big
loss in my case, but it might be a problem for some users.

Anyone having more detailed information? Perhaps some info concerning
insertion loss? (normally should be bigger when reducing the bandwidth)
