BG4EOH If I just want to expand the bandwidth and don't need shortwave, should I use the original equipment or a separate expansion unit?
BG2GFC BG4EOH For example, some firmware, such as the egcn190 I am currently using, can receive frequencies from 18 to 1300 MHz. However, the performance was very poor. I recommend either using a shortwave receiver or modifying the SI4732 chip.
