[CQ-Contest] Wideband noise

[zl1aih at ihug.co.nz]

Hi All,
For CQWW CW next week end, I checked an IC-
746PRO in a Multi-Single arrangement.   Listening 
with an IC-781, the 746 generated severe wideband 
noise during key-up condition. 
Reversing the rigs, the 781 was undetectable other 
than on the harmonic freqs.  

Has anyone else experienced this problem in a Multi 
operation with the 746PRO?
