RM Italy LA 250V VHF 2 meter Linear Amplifier with Fans: $635.00
The New RM Italy LA 250 VHF 2 meter Amplifier, the replacement of Popular VLA 200v . The LA-250 is a 200W 140-150MHz amplifier, at 1 to 20W input (13.6V 30A). It uses 4 Mitsubishi RD70 Mosfets mounted on a copper heat spreader (200x60x3mm). It is available in two versions one with and one without top mounted fans. There is an external PTT input but it can be used also without due to the built-in HF-VOX. The front panel features an LCD display which shows input power, output power, heat sink temp and output VSWR. There is the ability to change the intensity of the backlight. The CPU keeps an eye on input power, temperature and VSWR and will if necessary disable the amplifier from transmitting if there is fault. Any errors will also be recorded and will be available for later recall for diagnostic purposes by either the manufacturer or his distributors. Weight is approximately 4kg. Dimensions are approximately 240x420x70mm for the non fan version and an extra 10mm of height, 80mm, for the fan version.
