Supplied accessories

 DC power cord x1

*1  60 m band: Refer to applicable Amateur Radio regulations to your country.

Electronic specifications apply only to amateur bands. Receive sensitivity drops in the vicinity of the 1st IF frequency (8.248MHz) due to IF trapping.

Internal beat may occur during amateur band receive. Band scope (waterfall) screen may also display spurious signals other than receive signal.
