Can you help please.

Have just received a new HPD-07RH receiver and 72.070 dual conversion crystal to use on my existing Eclipse 7 QPCM transmitter.

Have connected battery & servo leads (earth wire on lower [bottom] pins) - but no response from transmitter. The receiver has no identification of pin use other than 'angled' corners at one end of pin panel and 'square' at battery end.

Turned on transmitter before receiver. Servos 'shivered' when power applied to receiver, but no response from transmitter.

Have switched crystal from an existing (working) receiver, but no success.

What should I be doing? Much appreciate your assistance and advice.

If this is your first QPCM receiver, then your Eclipse probably has all models in memory pre-set on PPM. Refer to Eclipse 7 Addendum for instructions on how to reset TX. Memory for each model using a QPCM receiver must be reprogrammed individually.
