I'm not that C100 is still in this set. It has the Sherwood audio
board in
it already.
The hiss definitely decreases when the RF GAIN is reduced and is
affected by
the NOTCH.

Steve -
I found the 'C100 mod' to be more effective than the Schottky diode
mod in
reducing 'hiss'.

I'm considering it, Lee. This receiver is nowhere near stock as it
is,
so I'm not wrecking a museum piece. It already has the Sherwood
audio
amp and a homebrewed version of the power supply mods.
I'm going to try the simple mod first to see what I think. The
experimenting is half the fun.
Thanks for the input -

While some of the mods may not be that complex...some certainly are.
Considering the quality, components used and all the design
work...they
are a bargain. Also, installation is not in all cases a walk in the
park...and will take a lot of time.
The roofing filter setup is complex and the parts are not cheap to
buy.
Also, the AGC/filter selection switch fits nicely into the rx and
is a
specially designed switch.
Have you guys really looked at what these several kits are??
So. I have a nice stock line for rag chew & original Drake
design..And
I have a DX killing, contest capable C line that works as well or
better
in some cases as a modern DSP high end rig. (less all the bells,
whistles and some neat interface features)
If, all you care about is fixing the 3rd mixer...issues..maybe you
could
roll your own....or $59.00 a couple hours and it's done?
Just Call Rob and ask him about the 3rd mixer...he can explain all
the
issues and how he solved them. Also...the power supply and audio
amp mod
gets lots of heat out of there and I the stability is superb then.
IMHO, I still think a Hot Rod C line and a comletely stock B line
is the
best of the Drake world....

Hi Don, All,
Yes, that's probably the reason why I did not want to buy the kits.
It may be even more fun figuring out something like that
myself......

Henry,
If we saw the schematics, we probably wouldn't pay the price for
the
kit, hi. That's his way of selling more.
