Mosquito's to Oberhausen 21-1-1944 ?

[Dave Wallace]

I don't know how many channels they could jam at one time. In the earlier days I believe they were only operating on one or two Oboe channels. I have some D-Day information that shows they were using 5 different channels simultaneously on a single target, a mix of Mk.I & Mk.II Oboe. That meant there were 10 ground stations assigned to track the 5 Mosquitos who were making their target runs at the same time. If the Germans could only jam a single channel at a time then it would be an effective solution to use more channels on any op to improve the results. PD failures were probably happening 25-30% of the time from what I can see in the ORBs. The more important the target, the more aircraft they assigned to ensure that some got through to mark or bomb.
Any ideas on how many channels they could jam at one time?

Hi Dave,
I think it depended on the number of jammers. Since the jammer had to be in sync with the signal, it would mean one jammer pr. signal. On the jamming sites I have seen on photos there were up to six jammers. When the war ended the LW had about 70 Oboe jammers, distributed among about 15 sites.
Especially on D-Day and the subsequent days the crews were complaining about jamming.

Hello Dave,

Thanks again for your valuable remarks and addktions: there is indeed a lot to think over!

Another option taken into consideration is Operation Steinbock, a renewed Luftwaffe bombing campaign against Great-Britain which started that evening.

Have a nice weekdnd! Marcel
