[Premium-Rx] Sayrosa 607B Drive Unit

[gandalfg8 at aol.com]

Ok, so not quite a Premium Receiver, and probably restricted to the UK, but I figured if anyone was to have one or more of these they might well be a PremRX member.


The 607B was a very nice 2 to 30MHz synthesiser used as the drive unit in the UK Diplomatic Service Piccolo radio system.

Both Sayrosa and Piccolo are long gone, and information has always been hard to come by, but I've just scanned the 607B Training Manual and 607B Technical Handbook and uploaded PDF versions of both to Mediafire.


This documentation is quite limited but so far is all I've ever seen for the 607B.


Both can be found in a single file at....

For what it's worth, my experience with these has been that by far the most common fault is the familiar shorted tantalum syndrome.
