Hi, I would check for something shorting the PA around where the PCB touches the rail or the screw puts down pressure on the PCB. This problem can

for the AFT05MS003 since it is no longer available. Please search this group for the details of that change: https://groups.google.com/g/hermes-lite/search?q=AFT05MS004N 73

The additional cable should have no effect on the output signal. It does, however, damp the input signal by about 3 dB since the feedback is parallel

Hi All, The BOM generation scripts are working for PDFs. These scripts allow me to create custom BOMs for different build options, different suppliers,

Hi List, I've dropped the TX LPFs from the first prototype and am going with a 10x10 cm board at first. It still may take several prototype
