[ARC5] NFBM IF Chip and a question

[Leslie Smith]

Hello Robert,

>From an earlier posting you mentioned your interest in single chip FM devices such as the MC3357, MC3359 and TDA7000.  I would be interested to read your experiences in using these.  My interest in these is this: simple 6m receivers or transceivers.  Homebrew gear for 6m is scarce, and commercial gear is expensive.  6m is an interesting and often underpopulated band.  

You may find me as "LNSmith" at OperaMail dot com.

Thanks

Les
