[Scan-DC] Pro651

My PSR800 has an option to skip the encrypted TG or play a tone (mine is a busy signal) when an encrypted TG is active, this gives me a chance to lock it out (or if in Wildcard mode, to lock in the TG,  and then lock it out) so I can track new TGs. Whistler has come out with an equivalent unit to the PSR800.

Side by side, I find my PSR800 a little more sensitive to weaker signals than any of my Unidens, but I cannot speak for the Whistlers.

1.  As of now I recommend using the Uniden 536.  GRE/Whistler scanners 
will drive you nuts if the target signal is encrypted as GRE/Whistler 
scanners do NOT mute the audio.  Uniden models do mute encrypted audio. 
The Uniden 536 is more RF input sensitive than the Uniden XT models. The 
decoded P25 audio is good quality and decodes P25 Phase 1 and 2.

2. Presently I am importing my Uniden 996XT files to Butel's ARC536PRO 
and using the KISS method creating 100 Favorite's Lists which will 
include most of the monitorable radio systems in VA (95 counties/35 
Independent cities, STARS, federal, etc.).  I finished FL-48 yesterday 
and have 51 to go.  Favorite Lists can be selected "on the fly" by 
entering the desired FL number to select to monitor or if previously 
selected to monitor deselect to stop monitoring. So far so good.  It is 
working as planned and sounds good. Interfaced with a GPS receiver with 
all the systems selected to monitor it is hands free monitoring when mobile.

3.  There probably will come a time when some radio system you want to 
monitor has converted to a DMR, i.e., MOTOTRBO. NXDN/NEXEDGE baseline. 
Currently there are no DMR scanners.  DMR users in the public safety, 
local govt, medical and private sectors are increasing monthly. A DMR 
receive system is not difficult to configure but it does take time and 
money and it will not be a scanner but one selected DMR frequency to 
monitor.  I have configured 3 DMR systems so far and all work great.  
There is no audio background noise on a  DMR received signal just 
silence until someone speaks.  The audio quality to me is comparable to 
commercial WBFM radio. Digital reception is unforgiving regarding 
peaking of the target frequency.  I recommend using an earlier vintage 
ICOM R7000 analog receiver modified for unfiltered audio or an analog 
scanner which supports offset frequency tuning.  R7000s have been 
available on EBAY and a few ham radio websites. A digital scanner can be 
used if it has an unfiltered audio output chassis connection.  A 10-15K 
resistor is inserted in output audio cable connected to the computer's 
Line In, not Mic,  audio connection. An external audio sound system is 
required.  DSDPLUS , a Windows level free software, is used. DMR Decode, 
also free, can also be run and will id the talkgroup of the user and 
talkgroup log histories are supported in csv format.  Installation help 
is available on the Radio Reference website in the Digital Software forum.
