:(I am in South Africa and the Proud owner of the Ten Tec Orion 1.
I was given the radio as an non working unit, and worked through it step by step to get it operational.
I wrote to TT several times to obtain an Alignment manual or procedure as you would get with the Japanese rigs to do an complete alignment.
Sad to say no amount of begging , coercing got any sort of result. Yes there are basic schematics on the TT web, but no PCB overlays or alignment instructions.
So it would seem at the time, by not making this info available , you were forced to ship it to the manufacturer for repair, something that is not worth the 16000Km of shipping or the crazy expense!.
Yesterday I read the TT service and repair dept. is closed due to the "global chip shortage".
WTF!.. So all TT users are now stuck with rigs which they have little info on and of which no parts are available for.
So sad since besides the quality / reliability flaws of the Orion, it was a darn great rig!.
TT how about making PCB overlays and service instructions available for these rigs?.
How come the Japanese are still churning out rigs and supporting them?.
Maybe time to go back to basics and use readily available garden variety parts , and allow users to fix their own equipment.
