Amateur radio enthusiasts are always on the lookout for ways to improve the performance of their equipment. In this blog post, we will be discussing a modification made to an SSB transceiver using the Easy Bitx kit for 40m. The modification involved replacing the IRF510 with an IRF150, resulting in an increase in RF power output from 3-5 watts to an impressive 20 watts.

 The Easy Bitx Kit

The Easy Bitx kit is an amateur radio transceiver kit that is designed for easy assembly by hobbyists. It is a popular kit due to its simplicity and affordability. The kit operates on a voltage of 12 volts for both the main exciter board and the power amplifier (PA), and provides 3-5 watts of RF output.

 The Modification

The modification made to the Easy Bitx kit involved replacing the original IRF510 PA transistor with an IRF150, which operates on a voltage of 35 volts. To achieve this, a Chinese voltage booster module was used to boost the input voltage to the PA transistor to 35 volts. The main exciter board still operates on 13.8 volts.

 The Result

The modification resulted in a significant increase in RF power output, from 3-5 watts to 20 watts. This is a considerable improvement and can make a significant difference in the quality of communication for the user. The video linked in the introduction shows the modified transceiver in action.


Easy Bitx kits are readily available from amateurradiokits.in and inkits.in. These kits are an excellent choice for beginners and experienced hobbyists alike, as they are easy to assemble and offer good performance. The modification described in this post is just one example of how these kits can be customized and improved to meet the user’s needs.


In conclusion, the Easy Bitx kit is an excellent choice for those looking to get into amateur radio or for those looking to build a simple yet functional transceiver. The modification described in this post shows that with a little bit of knowledge and some tinkering, significant improvements can be made to these kits. It is also worth noting that caution should be exercised when working with high voltages and that proper safety precautions should always be taken.
