Did take a look. The switch is on external and I don't think they added a 10 MHz source. Though when I start my 5370 without a source the right digit blinks 0 and stops after 5 seconds. Just blank. The ole forgot to turn the distribution amp on Regards Paul WB8TSL On Tue, Jan 7, 2020 at 5:34 P

OK, I tried the AD8055A op-amp in the buffer. Output now looks exactly like the output of the OCXO (square wave). Unloaded output is 3.2Vpp. Output into 50 ohms is +10dBm, nice and clean. So, if you buy one and want to add the components to get 10MHz sq-wave output, you need to add a TBA 1-1219 is
