Si4737 I2C Arduino Radio Breakout
hello
have designed breakout board arduino radio based on si4737, it's similar si4735 breakout improved , using i2c. sure it's 101% functional having difficulty running, modified 2 arduino libraries of si4735 compatible breakout , tried write own code without library power , tune station having same issue:
radio power-up command works won't tune, status request si4737 0x80 (clear send) , seems normal except won't tune.
when send power-up command hear small pop in speakers , can read 0x80, seek station won't work or auto seek, , no sound. please running got 40 of them , can't make work, spend days figure out, know it's simple, can't find it.
to first person helps me solve mail 1 of radio breakout boards free appreciation.
actual circuit , board shown below

ok,
so questions : sorry if spoon feeding, trying judge level.
are familiar rf signal lay out , requirements ?
have scope , spectrum analiser,
do have 1 of evaluation boards
