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.
