+ | ==== Extra tests : electronics heat importance ==== | ||
+ | After the conclusion of the calibration, I wanted to test if the heating of the electronics could have a noticable impact upon the deviation of the frequency. | ||
+ | |||
+ | So, I've tested my Ubitx with a WSPR spotting just after a cold boot (after at least one day without turning it on) and after a while, at least 30 minutes. | ||
