-This is a scheme I use sometimes at home with my base station in crossband mode: I tune one receiver to our local repeater, and the other to a simplex UHF frequency.  I can then use my handheld around the house and the yard with the "power" of my base station and antenna to get into the repeater.+This is a scheme I used to use at home with my base station in crossband mode: Tune one receiver to our local repeater, and the other to a simplex UHF frequency.  Then use the handheld around the house and the yard with the "power" of my base station and antenna to get into the repeater.

-One thing to keep in mind with crossband repeat is that the radio doing the repeating is transmitting every time someone transmits.  Using this scheme to listen to an hour long net means that the radio would transmit at <fc #ff0000>close to 100% duty cycle</fc>, which it may or may not be designed to do.  It would be best to use the lowest power setting and/or keep the use to a minimum.+The biggest flaw with this setup is that the radio doing the repeating is transmitting every time someone transmits, which means that the radio could transmit at <fc #ff0000>close to 100% duty cycle</fc>, which it may or may not be designed to do.  So it's best to use the lowest power setting and/or keep the use to a minimum.
