Hello, is possible to use it higher frequencies for WSPR ?

Hi Ondra,

I appreciate your interest in the project.

Indeed, it is a key parameter. I'm working on this issue, trying to extend upper frequency limit. Today I'm aiming to ~26...33 MHz limit in order to cover upper portion of shortwave band. The bottleneck is CPU clock value (270MHz). So, the jitter becomes an issue.
