[hpsdr] Cooling Requirements?

[kd5byb at bellsouth.net]

Not a problem.  I'll set it up in a spreadsheet where I can vary parameters such as the room air temperature, power input, airflow, etc...

I know at least one HPSDR user wanted a case that could be portable, so I think its very realistic that some HPSDR's may be operated in 100 deg F or 110 deg F conditions...

thanks and 73,
