General HP-40

The General HP-40 (often referred to as the General HP-40W) is a high-power 10-meter amateur mobile radio transceiver. It is widely considered the high-power version of the popular General Lee radio, featuring an integrated amplifier section to significantly increase output.
Key Technical Specifications
Power Output: Typically delivers 100+ Watts PEP (Peak Envelope Power) through four IRF-520 MOSFET finals.
Operating Modes: AM, FM, and PA (Public Address).
Frequency Range: Covers 28.015 to 28.585 MHz across six bands.
Power Requirements: Draws approximately 30 Amps at full power; it requires a direct connection to a strong power source (like a vehicle battery) and a low SWR reading (ideally below 1.5).
Notable Features
Audio Controls: Dual-stage variable echo controls and switchable talkback for monitoring your own transmission.
Noise Management: Includes a Noise Blanker (NB) and Automatic Noise Limiter (ANL) to reduce interference.
Aesthetics: Known for its blue LED channel display and meter lighting, with a built-in dimmer switch for night driving.
Comparison with General Lee
While the layout and features are nearly identical to the General Lee, the HP-40W includes a large heat sink on the bottom to cool its internal amplifier. It offers more than double the modulation power of the standard General Lee, which typically outputs around 45–50 watts.
