Morse trainer kit?
Guys,
I just developed a new board kit for a domestic customer and I am wondering if you guys will be interested as well. It draws 13 mA and 4x AAA size batteries will last quite long time. You can adjust tone from 600 to 1000 Hz and volume as well. You can plug in headphone or connect a small speaker. The buzzer will not be a part of the kit for worldwide as it is magnetic. Thanks, Adam |
yes that is bwtter AAA batteries because 9v batteries are expensive

开云体育Thanks for your interest. Please hold on. I am designing a set of 3. They can work together to make a complete FM band radio to support both voice and CW.Thanks, Adam 在 2024年12月7日,14:37,n7rgw via groups.io <larry.lovell@...> 写道:

Adam, I would be interested in a practice oscillator so I can practice CW keying on the go. Thanks, Sean Harrington On Mon, Dec 9, 2024 at 3:19?AM Adam Rong via <rongxh=[email protected]> wrote:
