Found space near the speaker to fit an open frame switched 2.5mm chassis
socket. Just a bit of grinding back of the socket and the radio housing
to fit it. Whether running wires up to the other end , to switch in and
out the external will destroy the headphone "clothes-hanger" reception
we will see.

I have one of these units and I think yours might be underperforming on
DAB - with mine Iv had a play, whereas I need about 2 feet of earphone
lead (rest wrapped tightlu around the unit) to get2 thick bars on FM I
can get full reception on DAB with only about 20 Cm extended. So hence
think your unit may be faulty. With the DAB bars I think it measures
quality rather than power; seems to go straight from 0 thick bars to
full bars in an instant with little inbetween! C+


Similarly 0 or 1 bar or 4 or 5 bars so perhaps decoded quality rather
than rf power. Makes sense I suppose as easier to grab the data without
adding anything to the rf stage and covers multipath interference which
simple rf strength would not.
