This Chinese radio can be windebanded to cover these frequencies, but what would it need to avoid spurious emissions? The 80,40,20,and 10 meter bands are filtered as standard. Any help would be gratefully received! I am in the UK, so would like to use the amateur 2km band (135-137 khz band). We can transmit at 1 watt, the output would also need a slider from 5 watts. How to do that would also be a help.
