I emailed ranger tech support last week. And chip sent me all the info that they had right now regarding the rci2970n2. I hope this info will help others. I will let Jeff put this were he thinks it should go.
Sorry for the delay. They are still working on a service manual for this model.
The 2970DX manual can be used for alignment as it is the same with exception of the driver and final transistor alignment which is as follows.
Turn carrier and mic gain control on front to minimum.
Turn mode switch to SSB
Key transmitter and set the following voltages measured on the gate of each transistor
Driver gate voltage 3.6VDC +-.1VDC
Final gate voltage 3.4VDC +- .1VDC
Bank 1 VR-2 gate voltage 3.5VDC +-.1VDC
Bank 2 VR-3 gate voltage 3.5VDC +-.1VDC
Please note also same alignment as in service manual except higher wattage listed below.
Carrier should be set to no more than 100 watts at max power AM
should be set to no more than 200 watts PEP at max power SSB
