Hi Arthur, Thanks for the extra information, it sounds like you may well have answered my question:-) As I commented to Bob, I was hoping I might be able to find an option that didn't require any internal access, I knew that was a long shot anyway but I quite liked the idea of a plug and go solution. Anyway, I can assure you that what you did wasn't just black magic, or at least that if it was the magic still works:-) Regards Nigel GM8PZR In a message dated 02/11/2014 01:27:18 GMT Standard Time, [email protected] writes:
Keep in mind that I made the modifications to my RFTG-u REF 1 almost 4 years ago and the details of why I did what I did are kind of foggy today. It was a pure hack but I *believe* that the circuitry as well as the jumpers were required, or at least I thought so. The big problem with getting something like this to work is that after spending a lot of time on it I generally go on to the next project and as long as what I did works, I forget about it because it is a one of a kind thing. The photo link below shows the 5Mhz buffer amp I connected to the TP in front of the oscillator that uses a mounting bracket that is secured by the BNC connector that outputs the 5Mhz. The 24V/2A power supply that I mounted on the back connects across the diode on the circuit board as shown. The transistors and other components of the modification that are mounted free form on the back of the J5 connector get the +5VDC from the header directly in back of J5. The wire on the left goes through an existing hole on the circuit board to connect to the fault LED. I was hoping that someone else would duplicate the modification just to reassure me that what I did wasn't black magic. It looks like Nigel is doing just that-thanks. http://i906.photobucket.com/albums/ac262/rjb1998/RFTG-uREF1_zps546e4c82.jpg _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
