Re: Ultimate3S v3.12 firmware release


Since there are provisions on the PA to control the power output, it’s a given that we will ask for automated staged power levels output to go with beacons. It’s only a matter of time.

Hi all


Firmware v3.12 was released yesterday at the same time as the new 5W HF PA kit. The main new feature is the code to send the raised cosine envelope shaping coefficients to the 5W HF PA kit. If you want to use the 5W HF PA kit with the Ultimate3S and you want to use the raised cosine envelope shaping then you MUST use v3.12 for it!


Features list:


- new parameter "Shaping {ms Max}" to configure raised cosine generation when using PA kit (see AN004)

- Convert Si5351A configuration and tone step algorithms to integer only

- Changed Backlight parameter to {Bright Timeout}, timeout specified in seconds, 1..999 seconds (0 means no timeout)

- When in extended WSPR mode, send the two WSPR pieces sequentially, not one each alternate cycle

- Write EEPROM version ID last when doing a factoryReset, so that if interrupted it repair at next power up 

- Removed flicker during GPS calibration when backlight control used and at full brightness

- Reference frequency defaults to 27,004,000 to be close to the usual crystal frequency
