[amsat-bb] Source of Mode S downconverters ?

I am looking to get another Mode S downconverter. I remember seeing one from Italy I think that could convert to either 2m or 440 for the converted signal but cant find the link anymore. I exchange emails with K5GNA but he is out of stock and may not have anymore for a while.

Any help/suggestions would be appreciated.

Thanks,
