 +In my case (I am located in Europe) I have used RWM at 14996 which is a time reference from Moscow transmitting clean carrier and the code is simple CW. 2 x each hour it also transmits for 10 minutes a continues wave which makes it very easy to zero beat.

 +You can also check with a accurate SDR receiver the 44.55 Mhz. I have used a sdrPlay and you can pick up the TXCO when the antenna is near the orion. Just switch to DSB and zero beat on the 44.55Mhz is easy to find.
