Using DSD Plus v1.101 and SDR#, I came across what could best be described as a "choppy" Capacity Plus Rest Channel.
It has the same sound and timing as a Capacity Plus rest channel idle burst, but the burst itself is chopped up in the waterfall display. DSDPlus v1.101 recognizes it as DMR Cap+ with DCC 10, but then mistakes the bursts for MS DATA and voice frames and tries to decode it as encrypted voice. It also does not display the LSN of the current frequency and just gives a "? CC" symbol. The rest channel idle burst stays put on one frequency for a couple minutes, then broadcasts the FCC CW ID and rotates to the next frequency in the system, so other than the odd decode it behaves like a regular Capacity Plus system.
In a few of the attached screenshots the channel activity window shows it as Connect Plus, however that was an error on my part not resetting DSDPlus between monitoring a nearby Connect Plus control channel and this rest channel.
I have no experience with Capacity Plus with RAS, but I thought that DSDPlus v1.101 could recognize it. Could that be what I'm seeing causing the erroneous encrypted voice decode?
I also caught a CW ID of "WPMS97", which was a typo in CPS by some radio tech who was trying to type WPMS976.
That license belongs to Fisher Wireless and the system appears to be located on Mt Otay near San Diego, CA (and sharing the same license as Fisher Wireless' Teamtalk Connect Plus site 119-1 also located there).
I've seen the "choppy" rest channel on the following frequencies, all DCC 10 and all are on the WPMS976 license:
451.2625
451.9125
452.2125
452.2375
452.3875
463.4375
463.9000
Anybody know what this is? Thanks for any help you guys can provide!
