Last Wednesday for the HF sked, I was hoping to get the Tracker Scout up and running.
It almost worked! But the transmitter is playing up. It would just send a burst of signal then stop. I thought it may be the 12V power supply overloading, and that may still be the problem, but when I put it onto the bigger 13.8V supply, it did not like it.
The receiver behaved very well.
I will be changing the display to a 2x16 LCD, not the OLED that is mounted.
There are 8 channels of coil sets on the board, but I will need to remove then to rewinding for other bands,
At the moment, they are 2.020Mhz, 4.010Mhz that was tuned to 3.630Mhz, 4.055Mhz, 5.300Mhz, 5.41Mhz, 7.97Mhz and 8.165Mhz.
I should be able to tune 160M, 80M, 60M, 40M and 30M bands with the coils there, but 20M may be too far.
And I do not know how high the transmitter will go.
As it is a single conversion radio, higher frequencies may be a problem anyway.
The original oscillators are all on a plug in board so that makes the mod an easy one.
Included is the 1.650Mhz crystal as well as the channel ones.
This in the Arduino proto version.
And a view of the main control board.
If folks are interested, I'll post a circuit of the mod as well as the Arduino code.
