Salutations to the Playmobil Frogman - I salute you.
Darwin speed my flippered friend!
This afternoon, The Register's Low Orbit Helium Assisted Navigator (LOHAN) team will assemble in Blighty's Baikonur (aka Brightwalton, Berkshire) ahead of tomorrow's flight of the Special Project Electronic Altitude Release System (SPEARS) control board. Specifically, this is a test flight to check that the aforementioned …
the frequency in use IS within the 70cm ham band which is allocated to ham radio on a secondary basis (the primary user is the military) another secondary user is ISM (Industrial, Scientific & Medical) which are allowed to operate from the air, license free but have a max power limit of 10mW.
those of us that launch balloons and hold ham licenses have to make sure that the balloon does not identify itself using our callsign while it is in the air since that would be an instant breach of our ham license conditions
As I contributed quite a few ideas for this.
Just a thought, but how hard would it be to hack a TV Rx module rinsed from a broken LCD as a makeshift 434Mhz receiver?
I am led to believe that they work fine at this frequency if the tuner is slightly modified by changing the voltage going to the tuning diode below or above the typical 33V used with a trimpot.
