I reviewed the DJ-X2000T (USA version) in June 2001 Monitoring Times.

I had fun with the limited range Flash Tune feature, but found
some drawbacks in the scanner I tested:

First, I very much appreciate your feedback on this.
How did the flash tune feature work for you? What is its limited range, and how
sensitive did it seem to be?


An annoying audio hiss was present even on the strongest of signals.


I understand that the "early" model X2000s had this hissing problem. I'm not sure,
but I think I may have read somewhere that this hissing problem had been corrected to
a degree on newer models. Have you heard any such tell?

The 110 millisecond squelch tail noise at the end of each transmission
was too long and grew tough to listen to.

I remember reading that as well. Primarily I am going to use this scanner for
listening on known, more continuous frequencies ... as opposed to doing a lot of
scanning for active frequencies. So in this instance, I could find it somewhat
acceptable to deal with a slow scan rate and longer squelch tails.

Probably my main concern would be whether or not the hissing problem has been
corrected, and just how well the flash tune feature works.

From my DJ-X2000T review in MT:

"...The "Flash Tune" feature is amazing.
Set the mode (e.g., AM, NFM, WFM), initiate the Flash Tune,
and the DJ-X2000T sits quietly until it detects a
strong signal (approx. -30 dBm, approx. 7100 uV)
within the 50 - 1300 MHz range.
At that point, the display changes shows the approximate
signal frequency and lets you hear the action.
You must set the mode (e.g., AM, NFM) ahead of time.
We used it to find and monitor 470 MHz transmissions
from someone using a walkie-talkie 25 feet away,
though it didn't detect a low power 170 MHz
wireless microphone at 5 feet."

"Our DJ-X2000T's Flash Tune also finds portable
cellular phone transmissions, but it displays 823 MHz
because the USA version is cellular disabled...."

I read that, but I don't know if it is true. Sorry.
