Link: YouKits HB-1B MK3 4 band QRP CW transceiver

New updated model features CW transceive on the 40/30/20/17/15 meter bands (previously 80/40/30/20).   Receiver sensitivity on 17m is reduced from other bands as it shares a common bandpass filter with 15m, which is why we are referring to this as a 4 band radio rather than 5.   Think of 17m as a free add-on accessory.   Transmit purity meets FCC requirements on all 5 bands.  Extended receive coverage beyond ham bands.   SWR meter added to display.   Sold fully assembled and ready to use.
