How is the slug in the r-4B notch adjustment adjusted. From the rear of the
can? Can’t see in there, and haven’t found a tool yet that will grab anything.
Or is it done with the little spring tail that connects to the notch control?
Thanks … Grant NQ5T

I suspect it means the final nail in the coffin of one of a long list of ham
radio's great companies (and great products). It's too bad, although Drake has
been out of our business for a long time. Their legacy will live on for a long
time to come. I've passed on my B-line and C-line, and was

That's true. But if one has an amplified stand it will work fine, too.

Why wouldn't you use the preamp? While there may be better preamp circuits out
there, even the preamp in an amplified Astatic stand sounds decent if it's used
properly. Turn it all the way down. Set the rig's mic gain at about 10:00, and
then SLOWLY advance the gain of the preamp for normal mod
That sounds perfectly normal. You shouldn't expect to see much more than 30-35
watts AVERAGE power with normal speech. So unless you're using a peak reading
watt meter, there may be no "low modulation".

Started about the same way. 1959. DX-40, one 7198 crystal, and a borrowed

After passing the General the next year I was rewarded with a 2nd hand SX-100.

Interesting in the different perspectives. I always found my R-4C to have a
noise blanker that was a "standard of comparison" for anything else. At least
on the noise here, it worked very well with a GUF-1 installed.
Dynamic range is another issue, but the NB was outstanding.

I'd have to pull mine out and open it to be sure, but my recollection is that
there are no slugs in those antenna coils.

No schematic that I saw, but there's a bit of information here:

Looks like the MN-75 may be a little lighter weight in terms of power
handling capability -- by just a little, not enough to matter.

I purchased a 1-A several years ago (probably in the late 90's), and
overall it is one of my favorite "collectible" radios. It worked
reasonably well -- seemingly -- so until yesterday I had actually
never even bothered to take it out of the cabinet. Just used it

I agree. I think the 2-B is a great receiver, chassis corrosion and all.
