[hpsdr] Cooling Requirements?

[Eric Ellison]

Ben

Like Field Day in GA! However, don't forget the interminable discussions on
Flex regarding 'noisy fans', physically and electrically!

Thanks
Eric

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,
