There was once a kit available from Tentec for this, now long gone.  WB5JNC and I have been bouncing ideas around on this subject for a couple of months. I finally implemented some of them and modded my Omni D for 10 MHz transmit last week. (Yes - this is the same Omni that quits on me after an hour or so!) I have started writing up the mod at the Tentec Wiki, keep an eye on this page:

I have only had time to make a couple of QSOs on 30m so far, but signal reports were good. As far as I can tell without a spectrum analyzer, the output is clean. I listened for likely spurs with a general coverage RX, and the ones that were there were weak, with the receiver sitting basically right under the antenna. Power output is consistent with the bands surrounding it - that is, 20m and 40m. My Omni is a little bit lower-powered on those lower bands, higher on 15m and 10m.

> Perhaps one of you  old time TENTEC gurus that lived through the birthcycle of this rig can help me.    It is a Model  545   S/N  0025  . Early production . The front panel has a 10.0 Mhz position on it  , but there is noapparent  circuitry in the radio for  generating output on that band. Is there someone aboard the  net here  , that can advise me of sourcesfor obtaining materials / info / tips / etc on executing the necessarysteps to take to get this rig fired  up on  30 Meters.  Thanks to anyone who can offer help   ,  in advance. 73  Dave W1DWZ
