Anyone have any ideas?

If you need a replacement the other poster gave you the details. But if
you want a MUCH more powerful keyer chip, for less, try

Thanks to everyone.. I called MFJ and they didn't have a replacement chip...
This is for a 422 keyer I bought off E-Bay Of course, it was suppose to be
working .. But it had a blown keyer chip.. It's on it's way back for a
refund.. shrug

Yeah, I used the K-10 chip in a QRP rig a while ago. They have a nice
product and it's small.. Actually I have the battery version of the K-12,
(using a watch battery) mounted in a mouse that I use for QRP.. Talk about
cool and easy to do!...

Well MFJ did not tell you the whole story (typical of them BTW)

They do have the Curtis 8045ABM (28-pin chip) that can be adopted to the
product. Some older 8044 chips (14-pin) do appear from time to time.

Ah, old memories. A quick google search brought up:

http://users.ox.ac.uk/~malcolm/radio/8044print.pdf

Should give you some information on the chip. No idea of where you
could get one, though.

I think it's another opportunist, via google groups.

It sounds like he's finally going to try to get the keyer going, and if
he can't, he's offering to sell the IC to the previous poster, who I
guess was looking for one.

Since there isn't much more involved than the IC, I'm not sure how one
determines that the rest of the circuitry is at fault (but can't be fixed)
but the IC isn't.

But since he didn't quote the message he was replying to, and the original
message must be quite old, who really knows?
