Thanks for you reply. What I am hoping to achieve is a continuous search creating constant white noise. I am told that if I disable the mute wire/pin, I could achieve this?
I could achieve this? If not this radio, do you know any that may be "hackable"?
Sir Martin mildon . . . . .
I have not yet been told of the need of muting the units speaker ?, but if that is the case / need
plugging in the headphones should accomplish the muting of the units speaker.
If no headphones, an 1/8 inch by 1 inch long round wooden dowel rod should also accomplish
the headphone jacks muting switch action.
HOWEVER . . . . .should this mute action be related to between station audio RUSH, I am afraid that you might just have a tiger by the tail there . . . .accomplishment wise.
Otherwise unshown . . . . . HEADPHONE JACK:
Hi thanks for your help and sorry for the late reply.. I think the ic number is bk1088e6056c
BK1088 ....

there appears to be no external control for muting
I suggest getting a more basic radio that doesn't have microprocessor control ... it would make modifying it easy
Yea that's it.. I'm trying make a spirit box but can't find any radios in the UK that I can hack but found loads in the US, not sure what type of radio to buy which easy to hack.ill take alook at this radio now.. thanks.

Nope . . . looks like that units u/p interfacing complexity would be modifying a continually refreshing digital stream from the u/p into the AM-FM radio block, with particular emphasis on the 15th data bit.
I then thought of the FM units that I got at the Dollar store, a decade in the past, but looks like they have almost dried up.
In looking up their potentiallly simpler chips being utilized, I accidentally found this gem, aside, which is a GOOD read anyhow.
Its very last 6 readers feed back comments revealed one extra thought.
Now, since you were commenting on disabling the muting to get white noise bursts between scanned stations, and it seem that you were suggesting CONTINIOUS scanning between stations.
Whereas, I was thinking of stopping on an unused frequency to get a continuous white noise output.
Now is there any chance that this units ACTUAL end use, is related to being a snake oil smathered " Franks box " as was stated by SHAWNA.

If so , no need for my submission of a zener diode generated , CONTINUOUS white noise source circuit.
