keying my Kenwood TS-530s
I have a question about keying my Kenwood TS-530s. I want to key this
directly from my computer but am having problems finding an interface. What kind of circuit does the ts530s use? Is it a grid block and if so can I use a grid block adapter and a normal serial interface? Thanks |

I believe that the keyer line voltage is negative on the tube rigs. Very easy to measure directly on your hand keyer and design appropriately. 73 ...
