Google research indicates that there was a company called Whistlewood Audio in the UK, about 10 
years ago and earlier, that made add-on boards to the Sony PCM-F1, 501 and 701 EIAJ digital recorder 
adapters. These boards grabbed the PCM stream and fed it to a cable, which then interfaced with a 
SPDIF transmitter box that was external to the Sony device. The 75-ohm SPDIF stream could then be 
converted for playback, dubbed to DAT or captred to DAW.

More Google time revealted a Paul Phippen was the brains behind this Whistlewood operation, but I 
can't find any sign of him or his products today.

Do any UK Listmembers know anything about this? Does anyone else make a SPDIF adapter for the PCM-F1 
or 501 boxes?
