microair receiving extra channels

[hihosland]

I have been flying a new microair installation and when the unit "wakes up" in response to receiving a signal on the selected primary frequency it also receives transmissions on other frequencies.

 

this with the "monitor" function switched off and the extra recieved signals are not on the standby frequency.

 

Any thoughts

I don't understand how that is possible. It is a single channel receiver, albeit that with the "Monitor" feature it samples a second channel periodically and will switch to it during a detected transmission.

 

The behaviour you describe does not seem possible. After all, it is receiving one channel, whether the mute is open or not. That is only an audio switch, triggered by received carrier level.

 

If it were "scanning" (which isn't an advertised function), then you would expect it to change channels only while the mute is closed. You should hear a complete transmission on whatever channel has broken the mute.

 

Perhaps a more detailed description of the behaviour may help.

 

You don't say whether the "other channels" are concurrent or one at a time and the mute behaviour between

It sounds like you have the scan function enabled..... (Yes it can scan!)

The extra channels you heard are programmed into the unit?
