[hpsdr] Pandora's Box

[Giuseppe Campana]

Hi Eric,

I can start to get some ideas about Pandora's Box

Can you point me to get the ATLAS/OZY/ecc ecc 's accurate dimensions ?

I know, here in Italy, a box maker for any equipment, from HIFI.....to WIFI

Do you remember my 3 years old SDR1000's Box ?
