Adam, thank you for sending this helpful information about this receiver kit. I assume that R2 can be my band of choice according to what Ohms I have on my Resistor (According to the chart).? Neat!

I am excited to build this and see what it will do. Thank you for giving us this privilege to try the beta version at minimum cost.

Thanks for sharing. Nice blue box. The final 2N2222 might help the RF output if you QSY to 20m band.

Thanks,

Matt,

Thanks. Shipped and the tracking number is updated in PayPal. Congratulations on the new article on CQ-DL. At the same time of February next year, Japan QEX will publish a long long article about ADX-S too, if I may disclose here.

Thanks,

Beta testers worldwide, your kits will be shipped Monday. For those who ordered 2 or more kits, you will get a tiny whip antenna for free. I haven’t decided if the whip antenna will be a part of the kit. The whip antenna is convenient but performance is not as good as a regular antenna.

Adam, I am not a technician but enjoy experimenting with circuits. I would check out the LED with your multimeter. Maybe it is defective. It sure looks like you did a great job in soldering.

I am still enjoying your version of the pixie and will send you a picture when I make a few more changes in the tin box I found at the dollar tree store.?
