Racal Feild phone UK PTC 404 in Other Radio Equipment Posted September 21, 2021 Hi, I've recently acquired a pair of PTC-404's. One is working fine but he other hums on whisper mode and is dead on normal. Just wondering if this thread is still active and if there are any more flow charts available, thanks
