I'm also fabricating crystal cans to contain the components that are interacting with others in a field effect manor.

Not yet, but adding it.

Also take note that C131 is emitting its own field effect. Sounds like C130, C131 and D49 need to be shielded and isolated from one another.

More local talk today. No Dx. Still no drift. There is no longer a heat problem. Thanks for the heads up on the typo. Yes, it is C-130.

The two things that no one else caught was the interaction between C130 and D49. That was causing a major drift problem. The other thing that no one caught was that Ranger on the 2950 put the 5p cap across the crystal terminals to lend some stability to the Circuit. Both of which are major.

I focused my investigation on Galaxy DX Series radio because I own a few of them and always have. I was aware of the drift problem and constantly reading and studying and working through different radio problems I decided to tackle this one. I've learned a few things in regards to the DX series...

I wasn't that crazy about this radio straight out of the box. But after a series of upgrades and improvements I am very pleased with this radio.

Special note. C-130 will interact in a negative way with D49 if it stands up straight against D49. Gently bend it to the left toward the brown connector. It contributes to the instability of the circuit. You will have to realign after you bend it.

I don't see that helping. But I highly recommend very carefully retinning all the connections Associated on the underside of the board of the entire oscillator circuit.

Another day of light dxing and locals. Still no drift.

There are three sets of vents on the Galaxy DX 2547.

You don't want to use the fan to draw the air out because the air will seek the path of least resistance. You always should force the air into the unit.

Forcing air in

Installed fan and grill on under side of my dx2547, same board as dx959b. Installed 5p cap across xtal3 pins. Touched up all solder points associated with that section. Covered section, to include xtal3 with hot glue as an insulator. Realigned. This will get you to the point to where your...

I eliminate the temperature change by cooling the unit. If I keep the unit cool, it never produces heat, consequently doesn't create a drifting problem due to heat. It also helps to touch up all the solder points for that section and to cover that section, using some wisdom of course, with hot...

No Dx but lots of local talk. Still no drift.

Talking with my locals all day on sideband and the radio still has not drifted one iota.

Any Galaxy. Shoot DX on it for 2 hours and see if it doesn't get hot as hell. The only cure is a heat sink with a built-in fan. And since I am serious about my dxing and I expect my radio to perform for long periods of time, I need to take it upon myself to make sure that it runs as cool as...

Yeah it's fine idle. But when you're on it for 2 hours talkin DX it changes and the radio gets hot as hell and that's running legal wattage.

I don't believe anyone's going to completely stop the drift on a Galaxy DX radio. However, there are several things we can do that very much minimizes any drift.it's still very much an upgrade to my Galaxy radios.
