Many of the units showed up in the early 90's on the European surplus market when Droitwich switched to 198 KHz as part of a global frequency realignment plan. I bought one and tried to convert it to 60 KHz. Not much luck. Still have it some where, got spoiled by Loran C and still use my Tracor 599 and an eight inch ferrite antenna here in Miami on 60 KHz.

Hi David, I had one of these years ago. As others have said, its a UK 200kHz receiver. full of pot core transformers. I decided it was not worth the effort to convert it to 198kHz. In the end I put a OCXO and divider in the case. Robert G8RPI. --- On Thu, 14/10/10, David C. Partridge <[email protected]> wrote: From: David C.

What is it for? I found nothing searching the archive, and Google didn't help much either. The Agilent site disclaimed all knowledge! I suspect it MIGHT be an off air frequency standard as it has 1MHz and 100kHz outputs and an aerial input. Any clues - or pointers to documentation?
