[TenTec] Frequency accuracy...

[Gary Tuck]

While the band was nothing to shout about here today and my 
neighborhood noise was bad--I thought I'd see where my readout was 
compared to WWV.

This is the method I've used in the past----

I tune WWV on USB with AGC off.  If the signal is strong enough, you 
can hear the background noise "whoooshing" as zero beat is approached.  
I then check against LSB to make sure it is the same.   I get this 
zerobeat at 9999.953 for 10 mhz WWV and 14999.927 for 15 mhz WWV after 
a two hour warm up period.

Now if this method is OK--my first question, then my Orion seems to be 
aging in the wrong direction.  It used to be off by about 25 hz at 
10mhz.  I read a post by K6SE a couple of years back about adjusting 
the TXCO.  Any thoughts or wisdom appreciated.  Now I know this might 
be a very small nit to pick but thought I'd ask if any are interested 
or bored enough to reply....
