Hello,
I¡¯m thinking about M0YYT¡¯s project ?bitx:
i want to do it from 0 to 100%
I have a couple of questions and comments:
1) Can you give me the value of the Tunning potentiometer in Kohms. How many turns? I can¡¯t find a model with a push button, quite to add one. Have you a part list for it.(Look on your ?bbitx)
2)I saw the need to replace the relays for an Axicom model. No pb for that.?
3)I saw that it is also necessary to modify the power supply of the Nextion display.(I want put one 3.2")? Put an inductaance, FT 114-43 with 70 turns. For arduino, modify the alim and add a resistance of 10 ohm + capacitors.
4) I saw a post that said we can get better performance by replacing transistors on the 45MHZ filter. Which model do you recommend for discrete components. (Transistors with 3 legs)
2n 3904 are good for AF section, replace all others, with??
Do you have any additional comments on other hardware changes.
thank's for your answers
