[ICOM] Icom 706MKIIG on low bands

[n5fnh at muckleroy.com]

That is what I was thinking.  I use the RF gain all the time to remove
noise.  Sometimes it is the only way I can understand what the transmitting
station is saying.  This is usually on signals that are about the same level
as the noise.  I'm using my 706 mobile, so there is always some sort of
noise I must deal with.

That's what the "attenuator" function is for, John.
If that isn't what you are looking for, simply turn your RF gain down.

Here is a kind of unusual question I have:  Is the Icom 706mKIIG too
sensitive to really use for low band DXing?

Let me explain.  I currently have an Icom 706 original.  The QST review
shows a MDS of -124dbm on 80 meters with the preamp off.  This seems about
right to me.  I run it with the preamp off on 30, 40 and 80, and it sounds
pretty good.  Not real noisy, but I can hear the DX well, and it didn't
overload very badly in last weekends contest on 80m.

For the 706MKIIG the QST review shows a MDS of -136 dbm with the preamp off
on 80m.  It seems to me that it is too sensitive.  At -136 DBM, 80 meters
will probably sound noisy as heck.  You can turn on the attenuator, but they
you are down to -116, which might be too low.  I did use a 706MKII last year
in the IARU contest and on 40m I had to run it with the attenuator due to
overloading and band noise (it shows a MDS of
-134 dbm on 80m).  With the attenuator on, I heard a couple of loud EU
stations, but not that many.

So, those that use it, what is the 706mKIIG like on the low bands?  Is it
almost too sensitive?  Will it still do ok with the attenuator on?
