Hi Gerald,
Its around 40 Khz? (HDSDR limitation - I have not found a way to enlarger this)) - example? -if the LO is set to 7110 the range will be 7090 - 7130.? Obviously you can scroll up and down the band as you like and with cat control, this is all automated.? On the monitor screen, you will however only see the 40khz part of the band.
