Galaxy DX 2547 Service Manual Excerpts
Support, support, support...The Galaxy support department was gracious enough to send the Galaxy Noise
Filter schematic with out a request! This is what is missing in most instances these days with large consumer
electronics companies. Their either to big to follow up on details, don't know were to get the information, or
plain don't care. Another reason for the lack of support for many radios is that the radios are designed, built
and documented off shore and shipped directly to the distributor. The distributor doesn't understand radio
technology nor do they understand end user customer support. All they see is the chance to make higher
profits by cutting out the important link between the factory over seas and themselves. Most of these radios
end up in yard sales or the trash soon after the purchase. Sure you can save a few bucks, but what do you
do when the thing quits or there is a technical design flaw. Who's out their to follow up on it. Don't think the
distributor or mail order company will. They'll drop it like a hot rock and find a new product to make profit on.
Not at Galaxy, they support their product 100% and beyond. To be honest there are a few companies that
support their products, but increasingly I see more products that are not supported at all. Have you ever tried
to get a service manual for the Uniden Washington base radio? They haven't supplied them for many years!

This transceiver has been aligned at the factory and does not require any adjustments at installation. The
required test equipment listed is used for the test setup or alignment shown in Figure 4-1 Transmitter Test
Setup and Figure 4-2 Receiver Test Setup. This test setup is used in part or total during the following
adjustments. Refer to Page 43 for adjustment location.
The Galaxy service manual has many more diagrams including circuit board layouts, block diagram and
schematics. Only a small sample have been included in this issue to give the reader a feel for how good
the manual is. The manual is professional in every way and will be an valuable asset to anyone who works
on the DX 2547.
I don't know for a fact, but judging by Galaxy's past history, much of the manual will probably be available
on their site before you know it. ©
