Trig – completion and testing

Well, after many hours of careful preparation and meter continuity testing of the two prime D plugs it came to the time to connect up. Realised I had managed to run out of positive bus connections so a brief pause whilst I change the behind the panel bus bar to give me up to 10 locations.

I also changed from the screw type connector block to a crimped ring connector with a handshake fly lead .. This means I can isolate and fully remove any powered item without affecting any others.

First power up and bingo .. All lights up … Default frequencies were changed to add 134.67 the ATIS for Jersey and then 119.45 (Tower) and

Engine cooling

They say 98% complete only 20% left .. But it does really feel nearer 5% now !!!

Another little but key job to get completed the rubber cooling duct bleed surround on the intake shrouds. Once glued I aim to secure every say 5 cm or so with a rivet and backing washer


Trig set up and test

Having setup the Trig Radio and Transponder it was time to final pin check and then setup for power only to realise id run out of main bus power points.

A short delay whilst I extend the bus bar to have a new setup .. Allowing for up to 10 points each with ringed connectors in preference to screw fit and also handshake fly leads meaning I can disconnect any power source in isolation of other elements.

Locate and temporarily connect the headphone mic sockets and crackle and we have life !


Then first power up and set the Jersey ATIS 134.67 and loud and clear …

Then press and hold the Function button on the transponder to setup the Config .. Very straightforward .. What fantastic equipment this is … Worked from first connect


I now have my imbedded call sign in G-SWAB 😃😃
