Re: [Elecraft] TCXO drift and calibration

[Wes]

Your first number is bogus, but generally speaking if your other numbers are 
correct, that does seem excessive.  That said, crystals do age and some of this 
depends on power on/off cycles.  I'm now to the point of leaving my K3S powered 
continuously.


I recently ran some drift tests and found that it takes about 25 minutes for my 
reference to settle to a point limited by measurement jitter.  There is an 
initial positive increase of a few Hz at power up (at room temperature) then a 
non-linear decrease of about 25 Hz.

Subsequently, I used method 2 and WWV, as described on page 53 of the Elecraft 
K3S manual.  The REF CAL frequency was lowered from 49.999.996 to 49.379.448.  
That seemed to make the signals on the 6 meter calling frequency sound like 
they should.

A few days ago, I caught a six meter opening and signals on 50.125 sounded 
higher pitched again.  I repeated the reference oscillator calibration again, 
using method 2.  Now, the REF CAL frequency is set to 49.379.110.  I have not 
had the opportunity to hear any six meter signals, since I changed the 
reference oscillator.

I am wondering if the REF CAL frequency change that I have seen in less than a 
year is normal, or whether I have a TCXO problem.

Any thoughts would be most appreciated.  Thanks in advance for any time taken

Re: [Elecraft] K3 Banner Question

[Dick Dievendorff]

As I am sure you’ll hear from others, it’s a K3 Utility configuration function. 
 The K3 Utility is free software on our web site.  

Follow the “support” link to software for the K-Line.  The same K3 Utility is 
used for K3 and K3S.

Banner is on the Configuration tab.

Just got a K3/100 (used).  Previous owner’s banner plays on power up.  I’ve 
looked through the owners manual and I can’t find how to change it.

Can someone give me a pointer on setting the banner?

[Elecraft] How to connect to KAT & KPA with the remote programs

[Howard Sherer]

I can connect OK using the KPA-500, & KAT-500 remote programs using the
host mode.

If I would like to use the connect mode, how do I determine the TCP server
port, and host /IP of my KPA & KAT devices?
