New FW release: various errors in FM modulation corrected


 

New FW release
Version v1.1-5

Changes:
- Solved a crash in the frequency menu
- Corrected various errors in FM modulation. (shifting, wrong deviation)

FM modulation should now work correctly for both low and high mode over the entire frequency range.
Be aware: In low mode around 46MHz and in high mode around 480MHz the fm modulation way deviate a bit due to complex PLL switching.


 

Erik,

Eagerly awaiting delivery of my TinySA. Where can I find the firmware?

Please go to the website indicated on the label inside the nice box that protected the tinySA


 

Arghhh. You are still waiting. http://tinysa.org


 

Thanks. Haven't received the unit yet.

Hi Erik

Now it is perfect and audio sound very good in a radio.

LOW OUTPUT 50MHz

AM: ?1000Hz=991HZ?? 5000HZ=4770Hz? ???At 1000Hz modulation 32% and CCIT distortion 2.4%

NFM: Audio tones spot on. ????At 1000Hz modulation deviation 5.4KHz and CCIT distortion 0.3% ?

WFM: At 100Hz tone modulation deviation 30KHz

HIGH OUTPUT 300MHz
NFM: Audio frequencies spot on.?? ?At 1000Hz modulation deviation 5.3KHz? CCIT distortion 1%

WFM: At 100Hz tone modulation deviation 30KHz

Con gratulation

Kind regards

Kurt
