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.

Tennessee red oak rig stand with satin lacquer finish is available as an accessory.
