Hi everyone,
I am trying transmission with ESP8266 and Si5351 modules and everything works fine with 10mW following the instructions at:
https://antrak.org.tr/blog/esp-wspr-simple-and-inexpensive-wspr-transmit...
Has anyone tried in the 2m band?
In CW mode Si5351 works well, in WSPR mode I have problems, the frequency entered in the program is very different from the one that comes out (I have to put 139.962 MHz to get 144.489) also the modulation is not correct, it seems the JT9 signal.
Some idea?
Thanks.
