Fix: In Settings > Radio , change Serial Baud Rate to 115200 and set RTS to "High" and DTR to "High". Then uncheck "Force Control Lines".
73 and happy weak-signal hunting.
Whether you are a casual weekend operator or a hardcore 160m DXer, delivers tangible benefits. The combination of better weak-signal decodes, faster multi-threaded performance, and ADIF 3.1.4 compliance makes it the most polished JTDX release in two years. jtdx 22160 new
The only caveats are the minor waterfall glitch on some Windows configurations and the experimental nature of multicore decoding. However, the developers have been responsive—a bug report thread on Groups.io shows three patches released within 10 days of launch. Fix: In Settings > Radio , change Serial
