Actually no. I've now heard this false information too many times.
As somebody who has prepared over 40 applications for FCC Type
Acceptance, and submitted monitoring equipment for FCC Type
Approval, I have first-hand experience. If somebody was so dumb as
to disclose to the FCC that a hacker could make the equipment unsuitable
for its intended use, the FCC would not allow the equipment to be used.
No certification would be forthcoming. On the other hand, if part
of the "turning-on" process was to load some bits from a bucket, this
disclosure must be part of the approval process. The FCC just might
require that the bits be checked for integrity, perhaps a checksum
or CRC.

Also, you can't adjust a milliwatt transmitter to produce a megawatt,
no matter how hard you try. The power output is allowed to be reduced
by software below the authorized maximum for that class of service.
You'd do much better at getting more power out by designing a custom
antenna coupling circuit so that the fixed output voltage could be fed
to a lower output impedance. Then you'd eventually run into fold-back
and overheating of those tiny RF transistors.

It's most likely, however, that a complete disclosure of the device
to be operated has not been made at all! Disclosing that a complete
disclosure has not been made, when in fact it's required, could
result in not only the loss of approval, but in fines as well.

Further, you can look at the disclaimer (the FCC Label) on any item
that had to be approved. It states quite clearly that modifications
render the device unapproved.

As for frequencies, the pseudo-random frequency-hop needs a center-
frequency that's pretty much set in stone (actually a quartz one).
Anybody can change quartz crystals. Again, modifications remove
approval. The typical user can operate unapproved equipment at
his own peril. However, it's unlikely that they will be caught
unless they leave their modified device on the lawn of the FCC's
standards office in Laurel, MD.

It's all moot. The device manufacturers don't want the competition
to know what's in those bits so their nature is not going to be
disclosed. Further, even if they provided the FPGA "source-code"
it's unlikely that most people would be able to use it at all.
Single-seat licenses for much of that stuff costs over US$500.00 -just
a bit too much to hack a US$39.99 device.

However, if you are a (choose your country) clone manufacturer,
it would be a pretty good deal to buy a US$39.99 board as a sample,
buy a US$500.00 software license, then clone 10,000 of these, selling
them at US$29.99 a pop. That's a US$300k profit for a US$539.99
investment and that's why you are not going to get the source-code!
