I've tried numerous times over the years to obtain a verification from CHIN, alas with no luck. On October 13 my SDR-IQ recorded several hours from MW, and when playing back I noted that CHIN was running "Caribbean Connection" with Jai Ojah-Maharaj with excellent strengths at times. The program was very enjoyable indeed, and I emailed Ojah-Maharaj attaching a good quality MP3 file. A most friendly reply came last night.
Another interesting facet of using SDRs like the IQ, SDR-14, Perseus etc: The spectrum you record can not only be DX-ed, but actually enjoyed, during playback. You never have time to do that in a DX session.
