But if you want to preserve the lifespan of both your transceiver last stage and amplifier, drive this latter with 80 W in. Said another way in reverse, the difference between running watts and a kilowatt is also 10dB. I took the example of a kW class amplifier as it is widespread in the ham community among hams who have the chance to be allowed to use so high powers. This, assisted by several fans and a sophisticated thermal management system, allowing the channel temperature of the LDMOS device to remain within limits which should ensure extended life, even with with heavy usage and yet quiet in operaiton with fans only operating when required. Imagine that all your ham shack is invaded with rigs and accessories, that your antenna, beam, vertical or wire is performing, proved by your hundreds QSLs received from far DX stations. So consider the biggest bargain in top brand 4 KW CW output linear amplifiers. But don't be offended by the ham telling you that you have a big mouth, because there are some good objective reasons in using such a power.

Just add power supply and go. Some of the parts included are: Some parts like rectifiers, oil cap and bleeder resistor are not included. The amplifier incorporates a pair of ARF RF Mosfets that are easily capable of supplying the required output power, they are mounted on a very large solid copper heatsink. I doubt anyone will purchase one of these tanks for it's intended use but what a plethora of dandy amplifier parts. One meter continually displays the power forward output.

A unique feature in all Emtron amplifiers is the overdrive control circuitry. Replacement of equipment in these circumstances is not an option. Maybe now I can get my computer fixed and my taxes done This is very close in color scheme to the one at the bottom, which is a light gray powder-coat finish, as is the one on the top right. It is virtually impossible to produce a broad distorted splatter signal in a Emtron amplifier.
