In my view, the GPS feature is absolutely worthless for DTRS. IMO, in the absence of a scanner with dynamic site roaming based on relative RSSI & BER values from adjacent sites (which you won't find in any scanner), the only viable option with DTRS is to manually test signal levels of each nearby site, at each and every location where you wish to use your scanner.
One of the things I really like about these scanners is that Group Quick Keys (GQK) can be used for sites and departments.
They have also increased the number of GQKs you can have in the BCDx36HP radios to 100 (10 with the 396T, 396XT, 996T, & 996XT)
I am planning using GQKs 1-70 for Departments and 71-99 for sites. DTRS Programming example:
GQK 1 = Arapahoe County Law agencies
GQK 2 = Jeffco Law
GQK 3 = Adams Law
GQK 10 = MACs & Network First
GQK 71 = Chevron Site (164)
GQK 72 = Lookout Mtn Site (108)
GQK 74 = Admin Site (101)
GQK 73 = Thorodin Site (105)
GQK 75 = Adams County Simulcast Site (322)
When I want to listen to Arapahoe Law I would use the following GQKs:
1, 71, 72, 74
For Jeffco:
2, 72, 74
Adams County:
3, 73, 75
MACS & Network First:
10, 71, 72, 73, 74, 75
The GPS is great if you are a new to the hobby or traveling. As a power user I am going to love having the ability to quickly turn sites on/off! Hoping my 536HP comes this week....
