I tried any possible power supply configurations to be sure that the internal switching regulator does not affect this. And it is absolutely unambiguouslyfor me - the problem is in STM32F1.
I've also tried LisaM with only a led test programm on it - same result. Ublox5 GPS receiver has noticeable worse receive nearby the board.
I found yet one forum topic about it
The solution could probably be to switch off the HSI after HSE and PLL init. As I see, the HSI is switched on in rcc_clock_setup_in_hse_12mhz_out_72mhz function and stays on from that point.
By adding rcc_osc_off(HSI) at the end of this function could probably help.
