[Premium-Rx] Racal RA6840 manual.

[vk3xyz]

Hi Tom,

Apologies for the bouncing email - all sorted now, the WIA changed service
providers recently and they reset all email forwarding. 

 

Haven't attempted a turn on as yet - I prefer to get as much info as I can
before doing that - plus I need time, trying to sort a power supply issue in
a comms tester at the moment.

 

Neither 6840 work from the what the seller told me, and one is missing both
the power supply and an A8 module (which he didn't tell me).

 

I note Federico  suggests contacting American milspec. I've sent them an
email.

 

Thanks

Greg
