Anyone 6666 not keying up

[TheRATT]

So my good ol' Quad 6 has stopped working.

When I key up, it looks like I'm keying and unkeying rapidly, about twice a second. Chunk chunk chunk chunk.

It is unmodified and I've tried a brand new mic and it didn't change things. I've reset it via the software.

Any ideas?

Maybe the supply voltage is too low?

The early made quad 6 had an issue where they burned a ground trace on the board before it went into the mic socket.

Are you using the oe stick mic replacement?

Sad to see such a great workhorse radio not operating so we need to get it back up. Even the best need a doctor sometimes I guess.

It was a brand new out of the bag stock mic. I'll take this sucker apart and take a look at that mic trace. It is at least 6 years old now!

Thank you for the tip, Eldorado!

(Terminus Eldorado by Ted Nugent now in my brain).

It is straight to my car battery and it powers my Yaesu FT-840 just fine?

It could be that you have your co-ax connections hooked up backwards. Try switching and see if that fixes the problem. Other than that it could be to low a deadkey or insufficient power supply. Good luck

It's been hooked up the same way since new, same antenna, same power.

The antenna has been used to work half the world so I'm sure that is OK!
