In addition to dimension generators, most dimensional travelers at
Progress Level 8 and beyond carry dimensional transceivers, which
A dimensional transceiver permits two-way communication across dimensions, although
dimensional static can sometimes hinder or block communications. The somewhat bulky PL 8 transceiver can be carried like a backpack; a handheld version is available at PL 9.
A dimensional transceiver must be calibrated to transmit signals to a given dimension. Assuming the coordinates have already been plotted using some kind of dimension generator (see above), calibrating the transceiver takes a
full-round action and requires a successful Computer Use check (DC 15), The PL 9 version can store the coordinates of up to five different dimensions.
