Expanding the frequencies on amateur radio is not permitted in many countries, however there are times when it falls into a grey area example NOV’s (notice of variation) temporary frequencies that HAMRADIO operators can experiment on. when this happens there is often only one way of getting access to the band up for grabs, and that is a simple temporary change in the band edges of an existing radio. DO CHECK WITH YOUR LICENCE!!
Why not use one of the most flexible radios on the market that also happens to be as cheap as chips, the Xiegu X6100 SDR QRP portable.
- Grab the radio and its power cable, get the radio plugged in..
- Grab a USB C cable insert into the dev port and plug the other end int a PC..
- Download Tera Term https://osdn.net/projects/ttssh2/releases/
- Install Tera Term
- Get your port numbers from device manager you can see mine here 10 and 11 your will be different.. make a note of them!
