Testing / demonstrating the Wouxun KG-UV920P's Two-Way Cross Band Repeat functionality (X-TWRPT mode). This test was done while inside a car, parked about 5 kilometers away from the repeater's physical location.
Actual cross band repeat in action:
VHF to UHF
• Field Test 1: KG-UV920...
UHF to VHF
• Field Test 1: KG-UV920...
The toy walkie talkie was used to demonstrate proximal UHF-UHF communication and also to demonstrate distal VHF-UHF and UHF-VHF communication via the repeater. Unfortunately, the toy walkie talkie does not have enough power to reach the repeater 5km away from its current location.
Here's how it works...
VHF to UHF
Transmission from Baofeng VHF radio (145.040) on high-power TX level (around 3-4W) is picked up by the VHF side (listening or RX side) of the KG-UV920P repeater system (5km away). The same transmission is simultaneously relayed to the UHF side of the repeater system and re-transmitted to the UHF frequency of the setup (462.700) using 30-35W (High) transmit power then finally, the Baofeng UHF radio receives the transmission.
