Hello All,

   When I moved from V11 to V12, I did not take apart my V11 boards, or cannibalize them in any way.  Now, I might have a use for them.

I've been a ham since 1970, and I have a weakness for the rigs I drooled over back then and could not dream of affording.  My current acquisition
in that vein is a Signal/One CX7A.  In 1970, this was the fanciest ham rig you could buy.  It was ahead of its time, and really too expensive.  The
radio is big, sized for adults, lots of knobs.... Of course, time has caught up with it, and any old IC7300 will blow it out of the water, feature-wise.

   One big thing that any radio of that vintage lacks, is a spectrum scope and waterfall.  Simply not doable with 1968 technology.

   The radio does an initial upconversion to 39-40MHz.  There's an RCA jack on the back that outputs that signal.

  Just for yuks, I hooked up my T41 V12 to that output - it showed a beautiful spectrum.  Waterfall & everything.  Only the frequencies were backward -
lowest frequency at the left, highest at the right.  And no pip showing to where the radio is tuned.

  I'm thinking that my V11 boards could be repurposed into a spectrum scope for the Signal/One.  I'd just need the Main board and the RF board and a
display.   I don't remember if the V11 will go that high...

My V11 doesn't work beyond about 32 MHz...

Jerry,

We are developing a new website featuring the T41. There will be a page highlighting User rigs. Would you possible send me a pic of the T41 and a short blurb about your implementation to include in the site?

Thanks,

Al
