27MHz & 458MHz-using-AX5043

Preliminary routine to test out Arduino Nano connected to the AX5043. My thanks to Jonathan (C-3PO) for all his help and to the author of: https://www.notblackmagic.com/bitsnpieces/ax5043/ The TX is set for ON for 8 secs and OFF for 2 secs. 7 July. Latest version PLL locks OK and transmits on 27 MHz CB radio) band. Antenna matching circuit from: https://www.onsemi.com/forum/t/faq-how-to-operate-ax5043-at-27-mhz-custom-matching-networks-for-ax5043/274 Very puzzling but TX circuit does not transmit on full power. (Module current about 2mA, should be about 50mA from data sheet.) Very slow progress on this project - still not sent any data or transmitted at usable power. I am still not sure that I have the hardware working properly (ax5043 connections and RF filter.) but I'm sure that an Arduino based approach is right for our r/c model submarine application. (Need for small size and low power. Raspberry Pi doesn't really fit the bill.) To add to the problems with this project, I see that the AX5043 device is to be discontinued at the end of 2022 so I am not going to do any more development. What a waste of everyone's time!
