OS456 Full - need pics

[N8YX]

All,

Does anyone have an OS456 w/ tone decode capabilities who could snap a few high-res pics of the middle of the board, where the 44-pin QFP is located? I want to compare it to my Lites and see what was omitted.

Thanks much - 73

Here you go...
I hope this helps.
I am a big fan of the OS456/556 + Probe for airband scanning, they are hard to beat even after 20 years!

Bagmouse,

Can you get a closeup of U13?

Thanks!

I had to cut the picture down to 50% because it was too big to post.
I will figure out a way to get you the original.
Thanks
