    I replaced an analog Nessie SWR meter with this one and I am very happy with the upgrade. I no longer have to set the Xmit level and the display is large and very easy to read.

    I like that it will support SSB and DMR level measurements. I added power pole connectors.

    Two Way Radios were quick to ship the unit and it was packaged securely. I am very happy with them and their service.
