Ten Tec 1210 Transverter
Can anyone help me with an operators manual/circuit diagram of the Ten Tec 1210 transverter, I suspect mine has a problem with the front-end, many spurious signals seem to be getting through, although it works ok otherwise. Screen shot shows IC7300 screen.

Re: Ten Tec 1210 Transverter
If you can't get your hands on an original manual, QST magazine for May 2001 had an article about converting it to 222MHz.
The full circuit is there with only a few (highlighted) component values changed. Terry |

Re: Ten Tec 1210 Transverter
Thanks Terry, I've already seen that QST mag for May 2001, it doesn't show the full diagram, I'm tempted to assume that Q12 is the receive rf amplifier, a BF988, and replace it.
