[R-390] Alignment

[Jim Temple]

Hello to the group,

I did the alignment, before my latest excapade, and it went well.  However,
I estimated the 150uV needed to obtain the 7volts diode load.

The signal generator is a Heathkit that has no meter, so the output is not
calibrated.  I measure the frequency with an HP freq counter, so I have
accurate frequencies.  I know that a calibrated output is not needed for any
of the alignment, except to set the 7volts at 150uV.

Can the 150uV output be accurately measured with a VOM??  I think the output
to be measured is RF voltage, so would a small RF detector, such as what is
in the ARRL handbook be suitable and accurate enough for the purpose.

Well, the receiver is still stable after 20min's burn in.  He. He.

Thanks for any input.

Sincerely,

Jim Temple
