[TenTec] Omni VI TCXO

[Steve Hunt]

Folks,

For anyone who may be interested, TT still carry the TCXO mod kit for the Omni VI - $66 shipped.

With the pound so strong against the dollar I couldn't resist :)

73,

  Sounds right to me.  However, I made the change primarily to have better 
  start-up stability without having to leave the power supply running 24/7. 
  >From a cold start, the OCXO's frequency makes a relatively large excursion 
  until it comes up to temperature.  That said, I found Ten Tec's TCXO to be 
  significantly more stable than the OCXO ever was.  After the mod, I don't 
  believe I saw more than a 20 Hz change in frequency at 14 MHz -- even from a 
  cold start.

  If Ten Tec no longer carriers that particular TCXO, many inexpensive 
  replacements are available with 0.5 ppm accuracy or better.  The difference 
  in price is generally a function of the TCXO's phase noise spec and absolute 
  stability required.
