In the cold season I finally got around to further developing my DIY CW TRX.
Here are the key data:
-60m, 40m 30m and 20m CW
-5 watts out
-7.4V operating voltage for 2 LiPo cells
-Voltage, SWR and Power display
-One hand operation
-Reflective display suitable for sunshine
The TX is ready, now it goes to the receiver.
-4 band filters, one for each band
-Analog CW band filter
There is no comprehensive documentation yet. I will provide the circuit diagram and the source code.
I’m not thinking of a kit for sale, but maybe someone is interested to do the job?
Here is a video clip of the current status, unfortunately only in German so far.
