[R-390] Call for measurements - 100dB carrier reading

Hi Dave

I can confirm that I used a DVM with a 10 Meg input impedance.

Can you clarify; do you want the 150uV applied to the input of the IF module?

If so, would you like me to arrange the 150uV across a fifty ohm
through termination and assume the loading of the IF is negligible? I
ask this because I can't easily measure 150uV in other than 50 ohms.

Graham
