Troubleshooting, Problem Possible Cause Remedy | Radio Shack PRO-92

To convert MHz to kHz, multiply the number of mega- hertz by 1,000:

30.62 (MHz) ⋅ 1000 = 30,620 kHz

To convert from kHz to MHz, divide the number of kilo- hertz by 1,000:

127,800 (kHz) ⎟ 1000 = 127.8 MHz

To convert MHz to meters, divide 300 by the number of megahertz:

300 ⎟ 50 MHz = 6 meters
