The wide-band setting works OK, but the "Selective" channel can't be calibrated, and is 15 dB low in gain. Looks like a popped front-end or a damaged input circuit. I've opened up the case, but all the innards are in screened metal boxes. Is this a common fault with this unit, and does anyone have experience of this fault? (and managed to fix it!) 73, Dave G3WCB IO91RM
