Gents, Please forgive me if this isn't the correct way or place to ask the following question, but I've pretty much exhausted all other possibilities... After almost 40 years of HF DXing, I finally decided to try QRSS and WSPR reception on 137 KHz. Knowing that my stock FT-920 isn't the best at frequency stability, I decided to find a dedicated rig - something simple, inexpensive, and yet stable enough to serve the intended purpose. I chose the IDC-136II direct conversion "receiver" from ICAS Enetrprises in Tokyo. I put the quote marks around the word receiver, because the unit is really just a down-converter, with the
lower mixing product at audio frequencies. I've read that people (VK2XV and others) have devised modifications for the IDC-136II, but I haven't been able to get any details. I'm wondering if anyone here is using one of these units, and (if so) what their experience with it has been. I'm especially interested in chasing down details on any modifications that have proven useful for enhancing dynamic range or sensitivity. Thanks very much.
