The 2009 era SMT (Sequential MultiTone Hellschreiber)- which completely filled a 08M- perhaps could benefit for starters. Perhaps shuffle your way thru' this near overwhelming swag !Įxtra: Given the increased 'M2' horsepower it may be worth re-considering digital & fuzzy modes that previously challenged basic PICAXEs. I've found MMTTY suitable for my PC soundcard based decoding needs in the past, but haven't kept up with such offerings as FLdigi. I must have another look it -any comments first appreciated. 2009 circuitry (below)? This should really be more widely promoted- that's if it's kept working reliably! My initial trials with such approaches,but using Jaycar's Keymark/Spiriton 433 MHz tx, were unsatisfactory.
MFB: It's assumed the rocket's AFSK encoder is still based around your ~Aug. Typical have been ST Hell and even VLF seismic precursors. I continue to swear by Spectran,as it's powerful but intuitively easy to drive,and have used it for all sorts of insights.
Although such superior soundcard software as Spectrum Lab exists,it's use can be complicated & with a steep learning curve.
