The TS-590SG is a lovely radio. I felt it needed more accuracy on the higher HF bands, which could have been calibrated I suppose without this TCXO but at least now I am cock-on when it comes to frequency accuracy. Also the military looking side plates are a cool addition. Looking forward to getting out and about with this and seeing how it performs.
Here are the side-plates: https://www.ebay.co.uk/itm/325234490051
