Glenn,
>>I looked at smd parts but there are two problems I think.? Poor Q generally and non standard values. The losses will be high in the filters. Might need some gain stage in there also.<<
For an interum board look at CoilCraft at the larger but not huge parts.? I have the
20M slopbucket and the band pass filter for TX is SMT and the RX Inptut filter is SMT.
It works well (no tune for TX).
Keep in mind if you knock the spurs and harmonics down my 20DB that may just be enough.
That and the power amp needs help anyway.? If the best it can do on 20M is 5W it would least?
be nice if it were reasonably clean.
Allison
