I am a B class Amateur licence holder. I can operate in VHF 144 - 148 MHz under 10 Watts of transmitting power.
I am using a Motorola AP73 portable radio. I access the Penang Hill repeater 9M2RBB most of the time using the orignal, 14 cm plastic coated antenna. I have a quarter-wave ground plane antenna on the top of my roof.
Motorola AP73, World Toughest Two Way Radio!
Check out the AP73 User Manual.
I have special interest in portable antennas.
