Strange lack of audio when it shows on the Screen ?

[Ben Town]

Found something strange and I could not change it.
Built the coin "cherry picking coin program" like in Andys 3030 book.
It worked fine in the test garden ,but when I bench tested some coins I don't have in the garden I got a strange lack of audio
Sen on auto, fast off, deep on, Fe coin, target trace and pinpoint on, audio in combined.
Was bench testing with a clad 50 and Morgan Silver dollar.
They would register in the accepted open areas and I could " draw" them with target trace, and the accept icon was on the screen but no sound on either when swiped with the coil.
I could put a silver dime or clad quarter and they would register and sound off just like you would expect.
I know if you have it set in anything besides Fe coin they will register up in the 1-2 Fe line instead of the 12 line when in Fe coin.
I did notice similar results with no audio sounds but that was when the coin was in the middle of nails in my one test, no sound but you could draw the coin with target trace .
Just curious as to what's happening there? Anyone see this before?
It's to cold to do anything but spend a little time in the test garden and bench test in the warm garage ;-)

Just guessing since you I'm not sure what pattern you are using but if it's the one I think it is you need to be sure the 01 to 04 lines are open from the low 30's on up.

It's the one in Andys 3030 book.
CTX 3030 Old US Coins Pattern set up just like the book.
I can try your recommendation and see if it allows thenm to sound off like I would expect.
Thanks

Also in looking at the patterns again your suggestion was recommended if Ground Coin was selected? I was testing in FE Coin . Maybe it will make a difference in both patterns.
I'll test it out tomorrow on the bench
Thanks

That worked, after opening the 1-4 lines as suggested the half and silver dollar ring they.
Bench testing is fun but it's going to be a long winter.

Hi Ben..........

You are using CLAD coins......Ferrous percentage..???...nickel is ferrous.....

Switch over to the OPEN screen...(NO DISC).....Getting the audio now...???

QED.

Matt.

P.S.

Cherry picking disc pattern may be ' Too tight' for clad....needs more open FE ...13 to 27.

I don't have Andy's book at hand to check pattern settings.

That is exactly the right answer.

And the bigger the silver stack, the more it pushes the CO numbers down towards a 1:34 (ish).

Ben, it's great that you're testing with actual coins you'd like to find...
I hope you have a short winter!

(Earlier this week we had snow and highs in the low teens...today it was in the mid 60's ???)
hh,

It was just two coins that would not respond in audio, 50 clad and Morgan silver dollar everything else I had to test worked and responded in the mode I was testing.
They would always sound off in an open screen , I wanted to get them to sound off in the old us coin mode and after opening the 1-4 line 30 and over did the job.
Not sure if and where I would use this mode but for me it's more of a learning experience with the new CTX to learn how to get it to do what I want and kinda understand it.
Thanks to all the responders
I know there will be more questions

What if you run with that pattern but Edit the Disc screen with the detector set for AutoAccept. After hearing the target, press the trace button to save it. Now what is the difference in the pattern?
Oh, have edit grid set to 1x1.

 

[amberjack]

block out any of the top right 1/4 of the screen at your own risk I think is the moral to this story

I'm beginning to realize that you may have something there!
I opened that area back up and solved my problem.

Build you a pattern with the screen dark from Fe 28 down and the rest open , run auto 3 , conductive tones and dig every solid crisp signal for a couple of weeks,,,,
epiphany will occur!
