Inexpensive Cross Band Repeater using 2 HT's
We had a successful run with the $30 RPT-2D repeater cable using two Baofeng HT's. One radio was set to talk on 446.000, the other was set to talk to our local repeater on 146.805. The cable links the mic/spk ports of the two radios. Had 6' of separation between the radio's to prevent the 2m side from locking in TX. Worked perfectly!
