Will the same IF connection work with a Tecsun PL-310?
The IF circuit should not be problem, but DRM still need tuners with GOOD phase noise property. Radios from Tecsun are notorious for this character.
Any kind of audio drop-out is worse than any kind of low quality audio: No audio, No log report.
