Hi Neville, The HP 5090A was made before the change from 200kHz to 198kHz by Radio 4. Unfortunately they are not easily changed to suit the new frequency (Lumped LC tuned circuits, 200kHz crystal and discrete divider). As far as I know this was a UK only product, hence the scarcity of information. I've only ever seen one! R4 is still going but has moved from Droitwich. B.T.W I've just listed a quartzlock 2A 198kHz locked standard on eBay item No. 260104635410

I can not find any technical information on this receiver, can anyone tell me is Droitwich still active as a stable frequency reference, and where can I find a manual for the receiver? cheers, Neville Michie _______________________________________________ time-nuts mailing list [email protected] https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts -------------------------------------------------------- Genetix Limited - Queensway, New Milton, Hampshire, BH25 5NN Registered in England No. 2660050 www.genetix.com Any opinions expressed in this email are those of the individual and not necessarily Genetix Ltd (Genetix) or any company associated with it.
