Stupid but known error in KX2: ATU stopped working - transmit power halved on bypass

Hi Armin,

The link you posted goes to a Gali-4 device. The devices in your photo are marked ‘84’. Are they Gali-84?

Are these equivalent devices? The circuit diagram shows them as SGA-7489

Thanks for the info, I am experiencing the tuning problem intermittently, perhaps when the radio is running warm. I’d suspected a cold solder joint but now I’ll check the comparative V on the resistors as you suggest.

Mark,
There is an upgrade for the tuner in the KX2.

That was a year ago. If only Colin had a better crystal ball. Several hundred at most? True for the first 24 hours after release, I hear.

All I can tell you is that I ordered this brick based on KK4DF’s advice… and it works. Unfortunately I can’t say anything about comparable types. I don’t know why it has such a print on it either.

The 84 is on the original brick… the replacement part has no print at all.
