The
RRDB Check For Changes feature is coming along very nicely.
I see a few benefits in using this tool such as:
1. This will show duplicate conv. frequencies, TGIDs, and trunking frequencies in the RRDB and I've seen many. Image 1 shows duplicates
Here's how the channels are compared to determine duplicates.
Conv Freq - Freq & Tone (CTCSS, DCS, NAC, Color Code, RAN/Area)
Trunk Freq
EDACS, LTR - Freq & LCN
MotoTRBO - Freq & LCN & Color Code
NXDN - Freq & LCN & RAN/Area
DMR One Freq - Freq & Color Code
NXDN One Freq - Freq & RAN/Area
TGID
DMR One Freq. - TGID & TDMA Slot
2. Sometimes a frequency or TGID may be rejected by the scanner because the frequency is out of band or the TGID is out of range. In that case the frequency or TGID will show all zeros.
3. Sometimes a frequency will be altered by the scanner. I'm guessing because it's not on a step and the scanner will round it to the nearest step. Image 2 shows that.
