BCD536HP can miss traffic under certain conditions
I am monitoring the TxWarn system in Harris County, TX and the surrounding counties.
I created a personal favorites list that has one system (TxWarn), 13 entities (departments), and 15 sites (towers).
I only wanted to monitor my local PD so when a transmission came up on my local PD I hit
the DEPT button so the scanner would only monitor my local PD.
I did not turn off any of the 15 sites using quick keys.
I found the 536HP would be silent for several seconds and then the scanner would
say "ten four" or "clear 107." The dispatcher was responding to a transmission that
the scanner never heard.
To verify this I broke out the PSR-800 with the same scan list (department) and talk group id's
that are in the 536HP. The only difference is the PSR-800 was set to monitor one specific
site only. The 536HP apparently was still scanning all 15 sites.
Sure enough, even though only one DEPT was being monitored, the 536HP missed several
transmissions that the PSR-800 picked up. Eventually the 536HP got "caught up" and was
in sync with the PSR-800 but it always lagged about 2 seconds behind. Some short
transmissions were missed entirely, and the longer ones lost the first 1 or 2 seconds.
Apparently, if you do not turn off any sites, and even though it is monitoring only one
department, the 536HP will still monitor all sites even though some of those sites
will never carry my local PD traffic.
So, if you wish to monitor a single entity via the DEPT key, it is best to turn off some
of the sites that do not carry that dept. You do this by use of the quick keys.
Does this sound like a feasible explanation of the problem?
