I bought a DJ-596T handy at Dayton that won't transmit.
(Not that it was misrepresented, both the seller and I discovered it had
a problem.)

Anyway, it visually appears to work, that is to say when keyed down the
red TX light and the LCD bar graph come on but there is no transmission
made. This is true for both 2m and 70cm.

It receives perfectly on both bands.

I downloaded the service manual from Alinco but it's description of the
TX circuit is limited at best. I'd like to take a try at fixing it
before sending it off for repair. Anyone here able to suggest where I
should be looking for the offending component?

Thanks for reading!
