[hpsdr] Icom 7300 ADC and frequency range

[Helmut]

Hi Ton,

 

As I didn't see an extra conversion unit in the schematics,  Icom is
probably using the 2. Nyquist zone  for the 4m Band.

Betreff: [hpsdr] Icom 7300 ADC and frequency range

 

Hi all,

 

My understanding is that the Icom 7300 uses the LTC2208-14 with a clock of
124 MHz.

The frequency range is specified to 74.8MHz

 

Does anybody know what trick Icom used to achieve that frequency range?

 

73,

Ton pa0tbr
