Jim,
Huh?
I don't see any of the MODS I have on my Sherwood R-4C as roll your
own...I guess if you can design and build printed circuit boards and
get all the parts including those neat front end filters you could.
Another way to get a Sherwood r-4C is get one from someone selling
thiers.
They do sell the kits so you can install them yourself..(Maybe a couple
at a time) I did a couple...I am a pretty good technitian and it was
not all that easy to do...it's pretty tight in most of the RX.
Anyways...Glad I already have it...just today I used the C line
including the L-4B, and had a great time....just nice & quiet and
signals just pop out when you get to them. I have the 2.4 KC frony end
roofing filters and it's cool to have weal signals nearby that do not
de-sense the weak ones.
73,
Lee

I can see your point, and I generally stay away from "feature-ism"
mods, but
I'm not opposed to technically sound mods that address design
deficiencies.
Arguably that audio output stage and low voltage power supply were not
state-of-the-art when the radio was manufactured, nor was the product
detector
and that mixer stage that picks up noise on AM, but we can assume that
Drake
was designing to a price point. Sherwood mods are only expensive when
purchased
from Sherwood, it's easy enough to roll your own for most of them if
you have
the skills. I don't care for most of the modern radios out there at
all, and
can't justify the expense - especially when I can spend a sawbuck or
two now
and then on some parts and make what I have the equal of anything
that's out
there in performance or listenablility.
Just my opinons.
