Brian Cook came to check the radios and avionics radios fine, nav antenna a beit weak and might need tweaking
DME partly worked, but didnt autotune with Com frequency.
Pins 18 and 20 on GTN750 plug 1004 look like they are reversed. Bitch of a job to change as the d-sub connector was jammed tight between the baggage wall and GTN rack... almost impossible to get at, and I thought id have to take the panel out completely... not good!
Eventually managed to lever the d sub off the connector block, and remoave the wires and add an extension to allow me to swap the leads at the dme dispaly. took ages , and ebevne longer to reassemble... Not impressed..... Continuity checks fine, but need to get Brian back next week to check it
