Hi. I have a Ranger SCI 69FFb4 radio that I would like to modify to operate on 11 meters. You tube had one short video on this, but it was not clear enough for me to follow. Hoping someone out here knows the steps for this and will give me directions. I would also like a owner and service manual if possiblr?
Thank you Silver Bullet

Hi...the b4 will need 75+ amps. Mega Watts sells some 50 amp units you can combine easily for 75-100amps. You will want a dedicated 20 amp 120VAC out to run them or two dedicated 15 amp 120VAC outlets (1) for each.
