Kenwood TS-590 official ALC mod

30w-alc120

Thanks to the yahoogroup of this transceiver, finally is available the mod to eliminate the dangerous power spike generated at the start of every transmission. The power spike can reach two times the power selected for few milliseconds, in the best-case this can trigger the input protections of several linear amplifiers.

Kenwood performs the mod for free also on the units out of warranty, but here in Italy the official Kenwood lab has asked me the purchase bill. I don’t have that bill because my rig was bought used from another OM and it already was out of warranty.

Here the doc: ts590-alc-fix
