Finally BBC is loud & clear

.....and with no pauses, crackles, or complete loss of picture. Thankfully the Swisscom electrician cam eround this morning to try and resolve the continuing problems with Bluewin TV (see here) and despite speaking no English we managed to maintain communication as he explained the klein problem. It transpired that the connection between the entrance point for the apartment block and our apartment had an extra wire which was "shorting" and acting as an extra "antenna". So far (touch wood) the electrician's work has had the desired effect.
