RM KL703 Reviews?

[gmham]

No I don’t get any swr issues at all 1.12 at 300w

Miss match on the patch leads probably

This is another owner mention about the high swr problem, can’t find the other owners post on FB but this is someone else reporting similiar. Yours okay ? Possibly just a batch that were built having this particular issue ?

HIGH SWR ON RM KL703......The RM KL703 is a great Amplify very well built in my opinion. Only One Snag is the high SWR it shows the Radio on high Power. To remade this add a chunky verible Capacitor (marked with Yellow Circle) to the input of the first Inductor to Ground. Then monitor the SWR on the Radio & adjust the Capacitor until SWR comes down & it's possible to get a standing Needle. . You could use fixed value Capacitors but you would have to experiment with different values. Sorry i don't know the value of the verible Capacitor but obviously RM didn't use enough Capacitance in the surface mout Capacitor that's installed.

Perfect as I say hopefully just a bad batch and possibly corrected on later built models.

You tested out the swr on the radio side when using linear ? one owner reporting a 2.0 swr with the linear .

Any chance of a proper guide with pics?
