Anyone know what firmware version is needed to support the new narrowband channels for the JT1000 ? Looking for same thing on MTS2000 as well, thought this would be part of the flascode on the MTS but looking at the decoder nothing found.

With the MTS I believe it has to be 6.xx or higher, JT1000...not sure, but my JT1000 made in 2001 has ver 3.02 and does narrowband including the 2.5KHz steps.

Thanks,
Have ver 03.00 in my JT and appears to take 2.5 KHz steps, anybody got one lower that's working with 2.5 steps ? (with what they're running for on the Bay lately I'm looking for a couple more but need that 2.5)
