[Elecraft] K2 4 MHz Osc Calibration with RWM Moscow [C1]

Good morning all. 

Not being able to receive WWV here in London, England, and not having an 
equivalent domestic service ourselves any more, I have been looking around 
for a signal against which to calibrate the 4 MHz oscillator. RWM (Moscow) 
may be suitable in that they transmit time info., on 4996, 9996 and 14996 
KHz and I can receive them hear loud and clear.

But I wish to check my logic as their signal is A1X at 1000 Hz so there is 
no carrier or voice against which to tune. Can I do the following ?

Set K2 to LSB (i.e. not CW in order to remove the CW offset)
Set SPOT (STP) tone to 1KHz
Zero beat with SPOT tone against RWM signal and then proceed with the N6KR 
method for setting the 4MHz oscillator (by setting the difference between 
the BFO and VFO to exactly 9996 with C22)

Comments gratefully received.

Many thanks
