I have been using my DX7 with a new Swallow 90 over the last two weeks, which has performed faultlessly. However during the initial installation there was the odd occasion when there was apparently no radio link between the transmitter and the model even though eveything looked okay at the receiving end ( both receiver led's glowing steady).The link was restored by turning the receiver off and back on. It would seem once the link is established there is no problem. Any idea's ???. Very pleased with the set, but wish it was more like my FF9.
