Hi Gary, I think I think that Maplin kit was covered in one of their old
magazines....I will have a look through the few I have. I wondered at first
whether it was a version of the the old R&EW project (CirKit) which was
called the Rubicron. That was a thing with two pcbs about Euro sized I
think. I definitely have all the gen on that as I have all the old mags in
archive. I also keep some Maplin cats as a source of data so there may be
something in them.....all you want then is a way of getting the time data to
your PC to reset the clock regularly. I think the first IC fell foul of
finger trouble I suspect it is a TL081CN which is an op-amp. that should be
enough to identify the diagram (the 567 is a tone decoder PLL used for
demod) It looks like the decoding was done in the PC where as the Rubicron
had a microcontroller chip on the 2nd pcb.

Subject: LF: Maplin kit
Hi all at LF,
A couple of weekends ago I visited the G-QRP Club Annual Mini Convention
at
Rochdale. On one of the junk stands I was rooting on I came accross a
Maplin
kit (or part of) for a Rugby Rx PCB No 1 & No 2, it cost me the princely
sum
of 20 pence. It consists of one board with a ferrite rod antenna, IC
(TL018CN), trimmer etc with 4 solder pinouts & one with 2 IC's (LM567CN &
TC4093BP), an LED, 9v regulator & preset control etc with 15 solder
pinouts
(several being GND. Does anyone know anything about this kit ? as I can't
find any info for it at tghe Maplin web site or on the internet.
Regards
Gary - G4WGT
