when using the software, and setting it to HF mode (10M) the channels are in 5K steps. that is why i was asking. thank you.Why would you think that? True amateur HF radios do not tune in steps but rather in smooth, usually 10Hz steps. The frequency display may only read out to 100Hz but the processor usually tunes in 10 Hz steps. 5 KHz steps is a CB/freeband thing. On the amateur bands a frequency of 28.573.8 is perfectly valid.
