This unit is a part of the UK's Diplomatic Wireless Service's "Piccolo" HF RTTY network.
I have acquired one of these & am trying to get it working. It accepts a 10MHz (or 1 or 5) reference & the output can be set to any frequency between 3MHz & 29,999,900Hz, in 100Hz steps. My unit is showing a "Fault" LED on the display, which I believe is inhibiting the output. I can see a varying frequency at the o/p socket, but only a few mV, not the 1v into 50R as is normal. I suspect that the fault indication is because there's nothing plugged into either the "Keying Frequency Control Input" nor the "Carrier Frequency Control Input" sockets. (There's also a "V.F. Inputs" & "Carrier Output (BCD)" sockets.) Can anyone help with a manual or connection details for the 2 input sockets, please? Many thanks, Mike M0MLM _______________________________________________ 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.
