Im using a Superstar360 with a variable power mod hooked up to a RM KLV350 amp. The proplem i have is when i adjust the power from the radio to 4 watts i key up and the relay in the amp starts to click rapidly and will only stop if i switch it back to stand-by. this happens not only on am + fm but also on ssb.
now the weird thing is if i use the amp with a standard 40 channel 4 watt rig it works like a dream.
i have checked my coax, antenna (a99) and power supply (20 amp max) and all seems ok.
Can anyone please help with a possable solution

Have you check the SWR each side of the amp with the amp off and on.

The KLV350 amp will take an input of 1 to 10 watts.

If the amp is new take it back and have it tested it may have a fault.

try turning up your carrier about a watt or 2 it seems its not high enough as if you dont put in enough wattage the relays will click rapidly try that and let me know how it goes 3s

cheers for the tips i've sorted it. it seems that the problem with the superstar was that too much rf was being reflected back through the coax making the relay in the burner lose its mind. to stop this all i did was fit a standard pl259 connecter in the coax between the rig and burner. its working like a dream now and im absolutly booming out. i can vary the power output from the rig up to 15 watts. using 10 watts i can push about 180 watts on fm out of the burner no problem.

i have had a couple of rm mobile amps and they both had issues. the first did the same as yours and i switched for another with higher wattage, might have been a 350, i'm not sure. anyhow , i did not have any luck with that one either. i sold it and put my texas star 500v back in. i'm not saying they are not good amps, i was driving otr and didn't have time to fool with all that mess as it was my busy season. it's always busy season.
