[TenTec] Orion Bottom Cover

[WILLIAM MANSEY]

Hole or NO hole - don't forget to take ambient room temperature into account when making adjustments to the Orion's TCXO.  In my case - - - My Orion now starts off about 20 Hz. low when first turned on.  This gradually moves up to about 5 Hz. high and it tends to stay there BUT! If I put the central air conditioner on the frequency gradually drops to about 10 Hz. low and then stays around THERE!    SO - IF you are wondering why you can not get your Orion to stay EXACTLY on frequency this is why.  A word, or two, about holes;  If you DO make an access hole in the bottom of your Orion - please take precautionary steps to protect against shorting any nearby connections should your alignment tool (if it has a conductive tip) misses the mark. There is quite a distance between the cover and the TCXO and this makes it hard to aim the alignment tool.  I have opted not to make any "ILLEGAL" holes in MY Orion.  73, Bill
