Combine the 2 tones together and the receiver has been zero beat. Older radios required warming the tubes and stabilizing the oscillator before zero beat could be achieved. It used to be interesting talking to a ham whose radio tubes were not quite warm enough and you had to chase their slowly shifting signal up or down the band until their radio was stabilized on frequency. Fortunately, modern radios have little to no receiver drift thanks to state of the art components and improved circuit design. Usually right on frequency out of the box. 73 OM de K3WR.
Quick Question, I have the IC-7300 and on the display right below band display I keep getting a flashing "OVF". Sometimes it is solid and a lot of times it flashes on and off. I tried tuning the frequency which the frequency did get tuned but I still get the flashing "OVF". What is wrong and how to I fix this? Have you ever experienced that on your IC-7300?
It means the RX is swamped with strong signals. If you have a preamp on turn it off, if you're on one of the low bands, such as 40/80/160m and especially at night turn on the attenuator. If that doesn't work reduce the RF gain.

thanks for that instructional video.
Thank you, I hope it helps
Very useful these wwv "clock", i was 63 hz off frequency on my icom 706
Glad it helped
Fantástic !

Cool, thanks!
