QCX freq/display calibration

 

Greetings all;
? So I put my QCX-20 on the air last night to check calibration. I am using my Yaesu FT-920 as my frequency standard. I noticed both TX/RX freq are a few kHz. I don’t recall anything written about calibration other than using the GPS RX to calibrate the XTAL.?

Has anyone else had a calibration issue? I haven’t seen any discussion about this unless I missed something.

You need the PPS signal to calibrate the crystal frequencies. The serial data is for time and info only. The calibration takes a few seconds and you should see a new value that most probably don't end in a lot of 0's.

Virus-free.

 

In the alignment menus look at 8.5 that tells you how to align the frequency without a GPS.

Jan is right.? Use the instructions in the manual.? I was able to bring mine right on frequency in just a few minutes.?

20m QCX msn 612
 

I would like to say thanks to those who suggested I RTFM.? I just did... Menu 8.5 Ref frq default is 27,004,000.? So once I figured out which way to go I found my actual oscillation is 27,004,750. +/-.? This gets me close enough where both TX/RX freq are just about right on with my Yaesu FT-920.? It may not be 100% but maybe 99%.? I am pleased.? At this point my rig is complete.I just need to figure out what I'm going to do with a case for it.? I am so happy.? I'll be doing my happy dance after my first QSO.??

Now I just wish I can get some quality time on the air when 20m IS open...lol
