4K00F1D Emission Designator

[zerg901]

Bellingham Washington FD just licensed portable radios with 14 emission designators. The narrowest is 4K00F1D. Anyone know what that would be? peter sz

A quick google search sent me back to the RR wiki with this.

4K00F1D 6.25 kHz single channel digital data

It is very likely that they are covering all their bases by throwing every emission designator in there that they "might" use

There is a big NEXEDGE vs P25 discussion underway at the 'Project25' group at Yahoogroups.com right now. Peter Sz

4K00 indicates a 4 kHz channel - to me anyhow. 6K25 would be a 6.25 kHz channel. Thats nearly a 50% difference. Maybe its close enough for govt work. Peter Sz

Channel width and occupied bandwidth are two different things.

Sort of like assuming your car is the same width as a lane on the interstate.

The FCC ULS shows "emission designators" for each frequency assignment. IIRC 4K00 indicates a 4 kHz wide channel, and technically 95% of the signal energy has to lie within that 4 KHz wide channel. Peter Sz
