IC706mkIIG attenuator	Reply
by G4IJE on December 28, 2003	Mail this to a friend!
I find that the 20dB of attenuation offered by the attenuator in the IC706mkIIG is bit too much most of the time. I reckon I would find 10dB more useful. I wonder if anyone has tried to modify the attenuator and if the components are reasonably accessible. I don't have a service manual so maybe someone can point me in the direction of the attenuator circuit (presumably a Pi or T resistive pad?). I'm reasonably handy with a soldering iron and would tackle surface mount components if necessary. Any help would be appreciated. 73 and Happy New Year, Paul G4IJE.

Since posting the above I have found an IC706 service manual PDF so I should be able to find the info I need, although if anyone has modified the attenuator in the IC706 I would still be pleased to hear from you. 73, Paul G4IJE.

20 dB is just over 3 S-units, which isn't much in my experience, especially when strong signals are almost always over S9. I've never used an IC706, but doesn't it have an RF gain control? Best rx es 73 de kt8k - Tim
