Customer states: It was packed poorly and shipped to me with damage. Just the volume control and mode switch.

Right. If someone says this to you, make the Dracula sign, then run don't walk the other way. I seem to remember the DX979 40-channel radio having a similar construction behind the front panel. Haven't seen one of those in years.

This is a repair so labor intensive that I intend to turn down the next one of these, unless there's a darn good reason. A damaged volume control and mode switch would not be all that intimidating in an older radio with a simpler front-panel construction. But the construction of the DX98VHP makes it a laborious expensive long, strange trip.

All the front-panel controls are glued together in one big multistory assembly. Here is the penthouse with the channel and counter display. The Mezzanine level with the slide switches is visible below it. The basement where the rotary controls are soldered is mostly hidden here.

Even if there's nothing wrong with the channel/counter display it will have to be removed. No other way to gain access to the layers below it.

Now you can see the solder side of the rotary-control board. The control shafts are pointing away, mostly obscured here.

So here's the new rotary-control board from Barkett ready to install.

So here is the broken mode selector. Just wasn't any way to piece it back together in place.

The new one still has a plastic sleeve on the lever. Has to be removed so it will fit the front-panel opening. This is a double-sided plate-through circuit board. All precaution should be observed before pulling the old switch loose from the pc board. If any of the pins still has solder bonding it to the metal sleeve that lines each hole, the sleeve may be damaged or completely removed from the pc board. Bad juju, that.

The challenge now is to get the display board and the control board lined up, and properly perpendicular before soldering them back together.

It is NOT as easy as it looks. The Panavise pc board holder helps. So does a steady third hand.

Almost done.

Of course, the last step after all the plugs are moved from the old board to the new is to line it all up with the holes in the metal front panel. First bit of advice. Don't tighten any fasteners at first. Just start the thread, don't tighten until all of them have had their threads started.

Also found this out.

There will be folks who asked why I replaced the entire control board. Only the one on the left looks damaged. It's not bent a lot, but this is after we tried to straighten it. Was worse before. Getting access to just one control takes the same labor as changing them all. Less, actually since we just install the new control board without trying to extract a part from it. Mostly this was to prevent finding out that one of the other four controls had hidden damage from the same impact. Sure don't want to have to do this twice to this radio.

And until my attitude improves, I don't want to do it again . At all.

I have never had a Galaxy radio on my bench. After seeing this I hope I don't ever have one. Designed for disposal, not repair.

And that's really all I can say without risking a banning for language.
