posticon Re: RM KL203 linear amplifier


Hi to all
This can use wide hf bands also, there is some mods to do it, I recall that most impotant is change better ferrite what can tolerate wide hf frqs. Also some parts is good to replace??, but that was most important, if find any info I'll put it in here.

Re: RM KL203 linear amplifier


They are illegal to use on 27MHz, as the max power in the UK IS 4 WATTS FM.

Depending on where you are you may be allowed 12 watts SSB, but no more.

As for amateur band operation, technically it would be allowed but the harmonic radiation would be suspect. In any case, most decent HF transceivers will output more power than this.
