Hi, I have a couple of 12MHz TCXOs that I think must have come from the LF community, probably they are ex Decca. I am trying to find the pinout and required supply voltage, and I am hoping that some

There is a Google ground view shot of Mal's house, and you can see the two masts in an adjacent field. I nearly missed them at first, but if you go to the highest magnification they seem to be there.
Exactly, it was an experimental system (MB7LF) that we ran for a while and demonstrated at the HF convention, which received on 136KHz and did a linear translation to 144MHz. This was use to overcome

73, Roelof, pa0rdt The only BFQ19s that I was able to source were SMT. Did you get them in another package? Did you need to use a heatsink with this transistor? 73 Stewart/G3YSX
