Hi, gang,
I have a SW4 that I listen to the local AM broadcast stations from time to time. The other night in the shack, I had it playing in the background and when I called it a night, I noticed the receiver was dark. Long story short, it popped a fuse, replaced said fuse, popped it again. Replaced the 1000mf@16v caps. Replaced diodes, some were shorted, and one open.
Life is good. Receiver powered up, I¡¯m listening to the local 1480kHz station.
However!!
When I peak the preselector, the audio distorts like it¡¯s being overdriven, back the preselector down a bit and nice clean audio. I for the life of me don¡¯t remember if the radio distorted on strong signals before or not. I¡¯m talking 20+ over S-9 signals from radio talk 1480. I tested the tubes, clean contacts, did the usual things.
So, before I start chasing my tail down the rabbit hole, is AM broadcast overload an issue with the SW4?

It's been some years since I had an SW4A, but I certainly don't remember overloading issues on the AM BC band (or anywhere else).? When I first got it, I lived in the NY City area, and later in Washington, DC, both of which have no shortage of high-power AM
stations.

One would think RL Drake would not produce a receiver that overloaded with any reasonable signal strength. By that I mean any signal within the range of the S-meter.
I'd look at the AGC string.

I suspect the AGC, too but haven¡¯t figured out how it works. I don¡¯t have a full size schematic, and have to flip between three iPad pages to see the schematic.

It should not overload you have another issue with the AGC, my guess.
Good luck

1480 is a regional frequency, 5KW maximum and possibly less. ?There are no 50 KW clear stations at least within the US.

Also 50KW, many clear channel:
Power Legend: U=unlimited time, D=daytime power, N=nighttime power, CH=?power. Class A unless otherwise specified. Omnidirectional antenna unless otherwise specified. A comma after the power indicates sunset. Whatever is after the comma is the night-time authorization, to avoid interfering with other, higher priority stations. Another comma indicates if it's a directional antenna system. DA means the station uses a directional antenna system. DA1 means the pattern is always directional, with the same pattern, day and night. DA2 means the station has two different patterns (protecting different stations), one for Day, and one for Night. DAN means the station broadcasts omnidirectionally (equal in all directions) Day, and directionally at Night. | 1090?kHz | Little Rock, Arkansas | 50?kW U, DAN | | 700?kHz | North Salt Lake City, Utah

KSL indeed may be 50 KW day and night non directional, but its not
clear channel any more.
There are no more clear channel frequencies in the US any more.?
Not sure when the clear channels were licensed to other stations.
It was a REAL SHAME when this happened!
Just to name a few:

Power
Legend: U=unlimited time, D=daytime power, N=nighttime power,
CH=?power.
Class A unless otherwise specified. Omnidirectional antenna
unless otherwise specified. A comma after the power indicates
sunset. Whatever is after the comma is the night-time
authorization, to avoid interfering with other, higher
priority stations. Another comma indicates if it's a
directional antenna system. DA means the station uses a
directional antenna system. DA1 means the pattern is always
directional, with the same pattern, day and night. DA2 means
the station has two different patterns (protecting different
stations), one for Day, and one for Night. DAN means the
station broadcasts omnidirectionally (equal in all directions)
Day, and directionally at Night.

"On May 29, 1980, the FCC voted to limit the protection for all clear-channel stations to a 750-mile (1,207 km) radius around the transmitter. Stations on those frequencies outside the area of protection were no longer required to sign off or power down after sundown" The implication is that Class A are still considered clear channel stations, just not as clear as they used to be. See also 73 -Jim NU0C On Sat, 16 Dec 2023 23:23:54 -0600 "Jim W7RY via groups.io" <jimw7ry@...> wrote: KSL indeed may be 50 KW day and night non directional, but its not clear
channel any more.
There are no more clear channel frequencies in the US any more.
Not sure when the clear channels were licensed to other stations.
It was a REAL SHAME when this happened!
Just to name a few:

otherwise specified. Omnidirectional antenna unless otherwise
specified. A comma after the power indicates sunset. Whatever is after
the comma is the night-time authorization, to avoid interfering with
other, higher priority stations. Another comma indicates if it's a
directional antenna system. DA means the station uses a directional
antenna system. DA1 means the pattern is always directional, with the
same pattern, day and night. DA2 means the station has two different
patterns (protecting different stations), one for Day, and one for
Night. DAN means the station broadcasts omnidirectionally (equal in
all directions) Day, and directionally at Night.

Hey, Guys, I read this list in Digest mode. I have lost count of the number of times that I have had to scroll through that entire list of stations in this thread.
When you reply to someone, please trim your back-quotes.? Thanks very much!

When I worked at KOA for 18 years, before all the dropins on 850 kHz, we covered 38 states at night. For decades WHDH protected KOA, but now nighttime AM radio has been ruined by the FCC policies. ?Follow the money.?

Not sure when the clear channels were licensed to other stations.
It was a REAL SHAME when this happened!
Just to name a few:

Also 50KW, many clear channel:
Power Legend: U=unlimited time, D=daytime power, N=nighttime
power, CH=?power. Class A unless otherwise specified. Omnidirectional
antenna unless otherwise specified. A comma after the power indicates sunset. Whatever is after the comma is the night-time authorization, to avoid interfering with other, higher priority stations. Another comma indicates if it's a directional antenna system.
DA means the station uses a directional antenna system. DA1 means the pattern is always directional, with the same pattern, day and night. DA2 means the station has two different patterns (protecting different stations), one for Day, and one for Night. DAN
means the station broadcasts omnidirectionally (equal in all directions) Day, and directionally at Night.

I think all the big money left AM...? just religious and conservative talk shows now.? Car manufacturers are not even
putting in on car radios anymore.
?
Just another thing we've lost.? ?I remember when I was young AM dxing late at night.? Clear channel KSL was nice
and clear in CA.

Not sure when the clear channels were licensed to other stations.
It was a REAL SHAME when this happened!
Just to name a few:

Power Legend: U=unlimited time, D=daytime power, N=nighttime power, CH=?power. Class A unless otherwise specified. Omnidirectional antenna unless otherwise specified. A comma after the power indicates sunset. Whatever is after the comma is the night-time authorization, to avoid interfering with other, higher priority stations. Another comma indicates if it's a directional antenna system. DA means the station uses a directional antenna system. DA1 means the pattern is always directional, with the same pattern, day and night. DA2 means the station has two different patterns (protecting different stations), one for Day, and one for Night. DAN means the station broadcasts omnidirectionally (equal in all directions) Day, and directionally at Night.
