'Kari? What level tacnet is Conductor going to be carrying? I think my character can manage a level 2, maybe a level 3...since the requirement is level*2 sensory channels
She's carrying Level 4, but as far as I know there's nothing stopping you from running a Level 4 as a Level 3 (just the lower "bonus cap", of course) if that's the most the members of your team can manage. Though, for most non-mages running 8 sensory channels is pretty easy (for a mage you might need to do something weird like run with a simrig active, which would provide your 5 meat-senses as channels). As a reminder, some of the common and inexpensive things that can act as channels:
*Biomonitors, including the 300 nuyen non-implant version
*Practically anything you can put in cybereyes. The recorder that comes free with them counts as one, as does Vision Enhancement, Vision Magnification, Low-Light, and Thermo. They don't specify whether or not Microscopic and Eye-Lights count.
*Practically anything you can put in cyberears. Again, in addition to the ear recording unit itself, the Select Sound Filter, Audio Enhancement, Improved Sensitivity, and Spatial Recognizer all apply. Not sure about the Balance Augmenter (it is technically a sensory upgrade, and I suppose it could tell other TacNet users what body position/orientation the person is in).
*Ultrasound sensors (non-implant or cybernetic)
*Drone sensors of all kinds (with each drone potentially be a different set of channels)
*Guncams, or for that matter, normal non-implant cameras linked to your PAN
*Recording devices, including radio scanners built into your PAN
*Geiger counters, chemsniffers, MADs, etc.
There's also the option (especially for mages) of not trying to participate at the level necessary to count as a subscriber in the network (ie, provide Rating x2 channels) but to just provide a few basic channels for pure data purposes. (The biomonitor being probably the most important one. If nothing else, everyone subscribing to the network will be able to see if you get shot, and hopefully we know where you are!)
