¿ªÔÆÌåÓýHi Dave, more to help with your testing rather than the L-R issue. The TX "failure" for such MFSK audio as
Olivia/Contestia/Thor/MFSK/Domino/IKFP/FSQ/RSID is "fixed" by
reducing the QDX (and I assume QMX) minimum samples from the 480
default to something like 120-180. I also reduce the rise/fall
times (2/40) to stop the raise cosine PTT inhibit, otherwise the
TX chops on and off. FM picture sub modes are generally not pretty
with random like line shifts. Minimum samples at 120 is however not low enough for Thor 56 or faster/wider. I have a series of command buttons on flrig to change this and the audio level as needed. The TX audio still sounds a little ragged, but I have had some
successful Olivia 8/250 QSO's VK>EU. One day I'll do some SDR
s/n threshold testing to see of there is any decode degradation. Cheers Bob VK2YQA
