i have a cobra 29 ltd classic that as far as i know nothing ha been done to it except the limiter ( d-11 ) is cut .. i am using it as a base station and it has been barefoot and working very decent . but im just trying to get out there just a little bit more . i saw this amp for sale for 70 bucks , it says ( super mod) on the front i will add a picture , but the guy i got it from said that its a great little amp and it had 2x22sc2290 pils. but he was selling it , lol . i hooked it up to a battery and turned the switch to the receive preamp from what the guy said and the radio speaker got louder . so i next tested my swr . on channel 20 its 1.8 and on channel 1 its 2.1 , channel 40 its 2.1 ....before installing the amp i had a 1.2 -1.4 across the channels , i am running the starduster antenna from the 70"s so i cant tune the antenna .. when i keyed the mike ( this hole time i have the power dial in the middle ) the antenna warning light came on .. so i let go right away , i then turned the dial all the way down , light still cam on.. so i then turned the power all the way up ..and the light does not come on anymore.
i made a contact a decent ways away and he said i sounded good , but when i turned the amp off he said i sounded better .
i know i have seen some posts about your dead key having to be low to run a amp ( that's why i did not key my down for more then 2 seconds ) . and maybe the radio needs some adjustment ?? anyone have any ideas ???
thanks in advance ,,,
