Re: [Elecraft] K3 no transmitting

Jorg, you can have your K3S repaired by Lutz Electronics in Switzerland. He supports all Elecraft radios and has a comprehensive workshop. That would save you some shipping costs and hopefully some time. https://lutz-electronics.ch https://lutz-electronics.ch 73, Alan - G4GNX South Coast UK

No TX power is a common problem, especially on DXpeditions. Other than power supply issues, it is usually one of three things: 1. Intending to use the BAND button, one holds down the right MODE button by mistake, putting the K3 into TX TEST mode. The "TX" icon flashes. But, since you

In the middle of ARRL DX CW, my K3 stopped transmitting. It did not shut off, it would go into transmit and there were small flickers in ALC when the meter was in that position, but no power out. Pushing the TUNE button resulted in the display saying "0 watts". I played with it for several

Just felt that a word of reassurance may be worthwhile. My older K3 (#228) has now worked about 35000 QSOs in Africa with appalling power problems - switching off the rig before the PSU would be a luxury indeed. Also losing power while transmitting has been quite frequent (and unavoidable). The

Joe, Many thanks for your help. I had been toying with the idea of buying a K3 for use at another QTH, but there the mains supply is not 100% reliable. If bad things can happen if the 13.8V supply shuts down as the result of a mains outage, that is serious. 73, Geoff GM4ESD Joe Planisky
