With 2 rtls, Unitrunker and DSD+ you can monitor multiple systems at once. Unitrunker allows each rtl to run as 3 receivers- your choice of voice receiver or control channel. The only issue to deal with is the frequencies need to be within about 2mhz. So for example Hennepin 2-001 has 851-853 and 857-860 frequencies so you need 2 rtls to cover it. I just redid my setup and have it setup so 2-001 and 1-009 control along with 1 voice receiver are on rtl 1 and 1-001 control and 1 voice are on stick 2. Each voice receiver needs it own session of DSD+ running.

Could you Post your Unitrunker file? so i can take a look at how it should be setup proper

Also are there any good guides out there to set two of them up?

This is the guide I used to learn the setup basics - written for older versions of the software but the basics are still the same http://www.rtl-sdr.com/rtl-sdr-tutorial-following-trunked-radio-unitrunker/

You should be able to Monitor Carver and Anoka with 2 dongles. Carver Cx channel is 852.07500 and Anoka is 853.38750: well within range of one another to monitor the signal channels on one dongle. You will need a second dongle for voice.

I have limited experience in the metro with SDR units, but the experience I have tells me that there is a ton of traffic on any one site. You will certainly want to prioritize your TGs so that you aren't stuck listening to Light Rail traffic at the expense of cooler stuff like MTC operations.

The simulcast issues I experience in Hugo make the dongles basically useless for monitoring ARMER here.
