This is a QRP radio that likes traveling. Mine has even been on a small boat ride in Adriatic sea... Or working DX SSB in a contest big time (with 9A1A antennas). If only a USB charge can be added. I am afraid that the radio will survive only so many case openings... Ignacy, NO9E -- Sent from: http://elecraft.365791.n2.nabble.com/
