RCI 2995

Can talkback be installed in the rci 2995 DX thanks RAY oldgoat (525)

Talkback and roger beeps and echo and blue lights and frozen drink machines can be installed inside any radio....well maybe not the frozen drink machines

Remove D67 from the board. Or install a switch to bypass it so you can turn it on and off.

I'm going to try this is my 2995DX and see how it goes. Mine is a current late model. Will post back how it does.

Also have an older 2970 non-DX that the sites say do the same deal to D78 but I have looked and looked and I can't find D78 on the board anywhere. Has anyone done this and can tell me exactly where to look for it? I've even seen it on the schematic but can't spot it on the board.

Good idea, tie one end of the switch to the diode and the other end back to the board, I wonder if a small pot installed in that circuit would give a guy a volume control?

It's a no go so far on the 95DX. Surface mount components and the SMT diodes are not marked on the board. There are a few leaded diodes but none of them are D78.

It should be just in front of T1 on 2950 board.

Thanks but it's not a 2950

Right, it's a 2970 non DX. It should still have an EPT295013Z main board, it just has a single final and the amplifier section attached to the bottom.

But you're not following the thread. It's 2995DX's that are being discussed.

Oh I am following the thread, and my apologies to the OP, but did you forget that you had posed this question?

Gotcha Warbird, didn't realize you were responding to the 2nd item. Next time I'm in the 2970 I'll look there for D78.

Thank you

Did anyone ever locate d67 on the newer dx boards to add talk back?
