Thank you for your interest In the Sony XDR-F1HD.
Update 5/28/20: I apologize for not responding to all emails and requests for upgrades over the last couple months. Due to all the general craziness, I've temporarily stopped taking in individual tuners for upgrade. Most of my time is being spent on other things. This may change as things evolve though. I will probably continue working on the few tuners I already have and offer them for sale, but I can't give a specific ETA for getting them done. It's "when I get to them". Sorry. I do appreciate your interest though.
Update 6/10/20: I have both a Level 1 and a Level 2 in progress. The Level 1 also has the Forced Analog Switch and Display Shutoff mods from the Level 2 features. No firm ETA yet.
I've upgraded, modified, and repaired nearly 500 Sony XDR-F1HD tuners since 2013. I'm proud of my work and I stand behind every tuner I work on with a "Fix It or Replace It" warranty: If something isn't right, tell me and I'll make it right. Your satisfaction is important to me.
Thanks to K6STI, K6JRF, and many others for sharing what they know about the XDR! I try to add something useful to the pool of XDR-F1HD knowledge and to extend the tuner’s service life for owners.
