Default Danby Mirowave Oven = lousy faraday cage

I would think 10mW-ish (+10dBm) leakage around the seal of an oven
would be reasonably safe, this is down from 1kW (+60dBm) output from
the magnetron.

50dB attenuation should have a marked impact on range for a cordless
phone.

Still all rather inconclusive, but maybe time to buy a leakage
detector just to be safe...

Next time you try this, put the oven in defrost mode for about 30
seconds. The "problem" should resolve itself. };^}

Your Motorola phone is 2.4 GHz model the results are interesting, but
not conclusive since the seal is probably only effective for some 10's
of dB's and your phone system has an effective path loss of perhaps 100 dB.
