Default Re: 4 Metre Converter - but which design?

Go for it. It could be most interesting if you have good paths to the East.
Holland have had the band for a few years and the Dutch are always keen.

They are just beyond my range for the most part but from where you are it could
be very good!

Just a question - what is your LO crystal and IF?
The 68.4MHz shown in one of the articles above surprised me slightly.

A good choice is 49MHz and 21MHz IF. Most designs for 4m use a 28MHz IF which is a particularly bad choice.
