And what are the changes, reading the documents doesn't really state them.

This document at the linked site does indeed state the changes... End Of Life assembly components being replaced with newer ones, a very common filing.

So Uniden wants to change the 536HP. Do you know why? Will the requested changes merely help their bottom line by swapping out something with something that will do the same thing but cheaper? Or possibly alow it to be marketed elsewhere in the world where presently it is not? Or, are there improvements to the scanner a user will benifite by? The documentation reads the 436HP originated in 2013... gives me cause to wonder why they would even bother to make improvements...

If components used in the original build are no longer available, they have to be replaced with newer components that are currently available to continue manufacturing the units.

Thanks missed it

What @fxdscon wrote in Post #3 indicates a good thing (potentially). Sometimes when components reach their End Of Life (EOL) a product is simply discontinued. Since Uniden has filed for a revision with replacement parts tends to indicate that the BCDx36HP series of scanners will continue to be produced (pending FCC approval of this action).

Didn’t see the “end of life” notation but it makes perfect sense. Thanks.

Has to do with RF radiation specifications ,AKA FCC Part 15 Certification. Changing the radio frequency components in the receiver.

And that makes better sense... I don’t believe the swapping of “like” components would require an updating with the FCC unless there were adverse changes relating to RF radiation. But even then, as long as the radiation pattern did not get larger than prescribed by the FCC by frequency, I wonder why the notification or request was even necessary. The scanner is not a transmitter. Next they will be testing anything containing electronic controls. Do refrigerators, toaster ovens, Electric dishwashers have to be submitted for approval? They all emit a small amount of RF.

Has anyone figured out how to adjust the TCXO in the BCD536HP?

@n1chu, we were not implying that EOL components drove this request. It was obvious that the Phase Lock Loop (PLL) circuit was slightly redesigned by the referenced letter. EOL components drove the redesign or the product line would have been sunsetted.

For those inquiring minds that want to know about an "FCC Class II Permissive Change" as this one is, see:

Even though I have an SDS200, I would never want to part with my 536. I'm glad Uniden is apparently continuing that unit. In as much as the 200 has a real "eye-candy" display, the 536 is has an excellent form-factor--- great size and shape for mobile mounting. And I think in some respects it can be a more solid performer that any Uniden scanner ever produced. Uniden's apparent decision to keep it in the current product line also means a higher resale value for folks looking to sell their units on the used market.

Ding ding ding! We have a winner. Exactly correct. Updates for EOL components. It is affecting most current models.
