Why should you consider purchasing and using the ME series QRP rigs when there are so many other modern ones with lots more features? The ME series rigs are simple thru hole boards with easy to find parts. There is no microprocessor or surface mount parts that are hard to find and replace. The sensitivity is unsurpassed. The circuitry is simple to understand. You can add many mods to it such as frequency display, RIT, keyer, 10 turn tuning, speaker amp, zero beat indicator, PWR/SWR meter, antenna tuner, etc. The low receiver drain is excellent for solar operation and portable use.
