Now that the x36 scanners support NXDN, is it going to be possible to set a 3.125KHz step size in Sentinel so that extra-narrow NXDN frequencies can be correctly identified and entered?
Also, will the SDS100 support NXDN with a 6.25KHz channel width option? I would think that if any arbitrary IF filter width can be set in SDR#, that correctly supporting 6.25KHz channels could be done in software, if not via a physical crystal filter.
The x36HPs seem to support it now Jon, somewhat.
When I was messing with that site this morning that was spewing out Alias's, I found the sites frequencies were wrong.
When I went in to the site to edit, Sentinel and the radio let me enter the first four digits right of the decimal point but it would truncate the last two digits for a 3.125 channel.
At least it does take them but who knows if the radio rounds the missing last two digits or not.
Actually, Sentinel does take all six digits right of the decimal point but the radio will truncate anything more than four digits.
The radios follow NXDN just fine like this and I doubt the radio has the selectivity to use say 454.4218750 instead of a strong signal on 454.4250.
At least that is what I'm seeing with a NXDN signal on 454.271875 and a neighbor P25 CC on 454.4250.
The radio is decoding the NXDN site but when I tune it to 454.4250, the audio sounds horrible and I do lose NXDN decode. I've not tried to see if it will decode the P25 signal that lives there or if I must purposely tune it 3.125 higher or 454.428125.
