Thank you for your interest In the Sony XDR-F1HD. My work on them is higher quality than my horrible website! Ha.
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.
As a supporter of public radio I was happy to donate a specially-modified XDR to Eugene public radio station KRVM to help improve the quality of their rebroadcast signal in the small mountain community of Oakridge, about 40 miles from Eugene (KAVE 88.5 Oakridge). They had been using a DaySequerra broadcast-grade HD receiver in Oakridge to receive KRVM-HD1 over the air from Eugene, then rebroadcast it locally. The DaySequerra died and would have been very expensive to repair or replace, so they were using a backup analog FM receiver that couldn't get a clean signal from Eugene. I offered the Sony XDR for them to try and it works great! It has a solid lock on KRVM-HD1, which then feeds the KAVE 88.5 transmitter. That XDR has been in continuous service since August 2014.
