spring reverb

[Fort Knox]

I'm picking up an FM radio station app. thru
a Pioneer SR-202w reverb unit when it is
hooked in to my system ...any ideas???

I'd try some different interconnect cables first. And clean the connectors with de-oxit or something similar.

...any ideas???

Yeah, but I'm not going to say it. :p

Generally, such things are AM stations - like WTOP - which in the old days was AM only, but they also have an FM simulcast these days at 103.5 - tho you will NOT be decoding an FM signal off a reverb spring. Most likely its the AM side - used to be any microphone type input in the area would pick up the AM side of that local station ... We'd hear it on the audio system at Church all the time ...

Probably an AM station that mentioned their FM side ...

digital reverbs ..from my exp. .also have continuity problems w/front pnl mech sw.
trying to operate in micro voltage circuits...so ..what works??

I used tube amps and spring reverbs and mics in my rock band
in the 60's and I don't recall hearing am ....radio interference
back then? could it be my present day tuner... in the circuit??

I have the same reception issues with the fillings in my teeth. I hate it when that happens.

But - its the basic difference between Amplitude Modulation and Frequency Modulation -
FM requires a much more sophisticated circuit to get the sound from the signal -
AM is a more brute force method that's hard to keep the sound OUT of a circuit ...

This reverb plays radio unplugged (from the wall..that is)....(RCA's still in the circuit)
(I guess that means.... Mr. Wornears wasn't kidding....

thanks for the advise..my patch bay looked atrocious ...
...and for what its worth ..
the coil reverb is good on the ears....I can hear more
music....:)

Well, you must be near some kind of powerful AM transmitter to make the springs oscillate harmonically ...
With that much power punching through the aether, I'd wonder what else is getting too much juice.

We'll I quit drinkin in 06' ...and toke up Water and Biking...
But..... I did find a fix ..another in line digital reverb circuit
(defeat button) did the job...by the way it was am1580 sports
radio....

Hmmm I sure haven't kept up with all those noisy old AM stations ...
Back in the 60s our church would pick up WTOP-AM (1500 kc) from Wheaton, MD

But yours?
Wow - its the old WPGC-AM! (aka radio Prince Georges County)

https://en.wikipedia.org/wiki/WJFK_(AM)

... 1580 kilohertz

On April 14, 1955, WPGC was issued a permit to raise power to 10,000 watts. It also moved its offices from Morningside to a facility in Hyattsville, Maryland. It later moved to Southeast, Washington, D.C. (https://en.wikipedia.org/wiki/Southeast,_Washington,_D.C.) in studios formerly used by WBUZ (95.5). In 1958, the station started simulcasting its programming on 95.5, by then renamed WRNC; the station is now WPGC-FM (https://en.wikipedia.org/wiki/WPGC-FM), which it became after WPGC-AM bought 95.5 outright.
On April 9, 1979 the FCC granted WPGC a permit to raise power from 10 kilowatts to 50 kilowatts directional.
The station subsequently changed their call sign on January 29 2013 to WJFK, matching call signs with sister station WJFK-FM (https://en.wikipedia.org/wiki/WJFK-FM) "106.7 The Fan."
