Found this old, battered thing packed away the other day! ...Who remembers them?


Don't think I ever saw one of these. Bit of a stab in the dark - without knowing the crystal frequency.teckniqs wrote:What frequency was it set to??
I missed one. Eyes or brain fart - not sure. I'll second your guess after a recount.Analyser wrote:Sure I have one of these in my drawer of pirate history and I'll guess the frequency as being 106.5MHz. Shame it's so battered or you could check!
8.192MHz crystal (removed), 500Hz loop reference frequency ?builtinashed wrote:I missed one. Eyes or brain fart - not sure.

Actually think I had a brain fart on the crystal frequency too. If any of what I said before is right, I think it should have been 4.096MHz (not 8.192MHz). Output from the 4060 looks to be on pin 2, which I think is Q13. If I remember rightly, that means divide rate of 2 to the power of 13, or 8192, so if the loop reference frequency is 500Hz, it should be 4.096MHz. If you've got one in your back pocket, you could put it in and try it out......teckniqs wrote:I was given it about 15 years ago from somebody in south London, maybe it came out of an old Hyper FM rig.
....the crystal has broken away and was not removed.
Who, by the power of google, seem to have been on 106.5 at one time........teckniqs wrote:maybe it came out of an old Hyper FM rig.
