Albrecht AE-540 2-Meter Amateur FM Mobile Transceiver Service Manual

Problems with AE 540 -

Factory preset USA frequency range

Problem:

In transmit mode the frequency limits are only between

144 and 148 MHz, while reception is still tunable between 136 and 174 MHz

Solution:

On the inner side of the front PCB (opening of speaker-side cabinet necessary) is a zero-Ohms SMD resistor as jumper, which is nowhere mentioned in the documentation. The jumper is between

CPU and channel switch, situated between R 206 and R 203/207. Please see photo and markings.

After deleting this jumper (unsolder carefully!) the radio operates in the whole frequency range TX and RX

126 - 174MHz.

Note: European regulations about radio amateur service do not allow use of extended frequency range transceivers n restriktiver als in all countries! Please read national instructions before using extended transceiver equipments !
