[Kenwood] Passband Relays in TS-430S

Wed Jan 28 10:57:34 EST 2015

Now I do not know if this method suggested for the 430S would fix your 
radio or not. Maybe the Pro's here on the list can say?
I know as simple, and scary sounding as that fix is. for this 430S it 
was incredible!!! 10 Meters was intermittent Like Robert said below 
here, sometimes it worked some times not. And as an also SWLer The 49 
Meter bad absolutely did not exist! It was sooo bad that not a single 
carrier from those megawatt broadcast stations couldn't even be 
detected in SSB mode it was that deaf.
But after running that fix, WOW 10 meters works great all the time now, 
and 49 meters has signals that actually peg the meter sometimes! What 90 
db over S9?
I'm just worried about scanning with this and the relays constantly 
clunking around.
