selective measurements
Plastic tuning screwdriver
Notes:
•
Level measurements during tuning & checking frequency response of P4RX are relative. Hence any ordinary
wide band or selective level meter with a frequency range 10 kHz to 1000 kHz can be used. Normally a wide
band level meter will be sensitive enough. If more sensitivity is required, use a selective one. Be careful when
using a wide band meter, as unwanted signals may disturb the measurement.
•
The same Rx tuning adapter P4LM used for ETL 41 and ETL500 can be used for ETL600. However, if two
shorting wires are present on the P4LM, they must be removed. The position of these 2 shorting wires - if
present - will be across C1-C9 & C2-C10, under the sub-board.
