2) Apply a CW signal at the low end frequency for RF Frequency Band 1, (0.009
MHz), at an input level of +40 dB(µV).
3) Tune the receiver for a maximum indication on the front panel analog meter,
the front panel digital meter should in40 dB(µV) ±2.0 dB. If not, refer to
Table 4.6 and adjust the component listed under the "Low" column for "RF Ad-
justments" for +40 dB(µV) ±2.0 dB.
4) Apply a CW signal at the high end frequency for RF Frequency Band 1 (0.035
MHz) at an input level of +40 dB(µV).
5) Tune the receiver for a maximum indication on the front panel analog meter,
the front panel digital meter should in40 dB(µV) ±2.0 dB. If not, refer to
Table 4.6 and adjust the component listed under the "High" column for "RF Ad-
justments" for +40 dB(µV) ±2.0 dB.
6) Repeat substeps 1 thru 5 until RF Frequency Band 1 meets the stated frequency
range amplitude specification, ±2.0 dB.
e. Repeat Steps b thru d for RF Frequency Band 2-9 using the respective high, mid-
dle, low frequencies for each RF Frequency Band.
