RM ITALY HLA305V PLUS  HF linear amplifier 300W ventilator

RM ITALY HLA305V PLUS HF linear amplifier 300W ventilator. A full range HF amplifier with automatic or manual band switching.

It is specifically recommended for use only with transceivers up to 15W (e.g. FT-817/818, SUNSDR2 QRP and PRO, or handheld transceivers).

It works great with the Flex Radio or SUNSDR, you can use this amp for flex-1500 makes QSOs world wide.

Also works great on Elecraft KX3 radio, It will work well with all the QRP rigs plug and play.

The built-in protection circuitry automatically sounds and or bypasses the amp in situations where damage could be caused to the circuitry or when spurious emissions are excessively high due to incorrect band selection.

Note: Unfortunately the HLA series amplifiers were not originally designed for high speed CW operation. The problem is due to the fact that the bias is switched on with incoming RF and there is a rise time of about 25ms. However with a small modification this can be reduced quite effectively. Ask us a quotation for this modification!

Warranty: The unit is covered by a two-year manufacturer's warranty, except for end transistors, if failure is due to causes such as: indirect or secondary effects of lightning, overheating, poor ventilation, exceeding specifications such as: overvoltage, high drive power, poor antenna SWR or antenna breakage. To avoid controversy, it is important to note that end transistors are not usually destroyed by other causes. By ordering you accept these warranty conditions, if not, we recommend not to order the device.

It is not recommended for old model FT-897 because of the transistors in the radio power control circuit.
