The missing L3 has arrived and after installing it I now have transmit output when the subrx is activated

Thanks to information from Charles Allen (who suffered the same issue) and help from Dale at elecraft, the problem has now been identified as a subin board production defect The inductor (L3) that supples bias to switch the tx/rx pin diode to the tx path on the board was not, and had never been fitted, hence drive doesnt get switched to the tx path The missing inductor is on its way from CA The board was supplied with the subrx last november. Wayne assures me all subin boards are now 100% tested Dave ww2r Message: 11 Date: Sat, 14 Feb 2009 02:09:47 -0500 From: ww...@g4fre.com Subject: [Elecraft] K3: activating sub receiver disables tx ?

(and what the cure was?) In a k3 with atu xverter interface and subrx. Ant 1 is selected vfo a is set to cw mode and receives OK. Keying it shows rf output on the k3 power meter and the external power meter vfo b is set to cw mode on the same band. Doing an a/b swap and it receives OK, Keying it shows rf output on the k3 power meter and the external power meter if I activate split (rx a tx b) using the above settings, keying shows rf output on the k3 power meter and the external power meter however if I activate the subreceiver with split (still) enabled keying shows NO rf output on the k3 power meter and NO rf on the external power meter. A signal can be heard on a monitor receiver. Also if I leave the subreceiver activated and turn off the split (no split) keying still shows NO rf output on the k3 power meter and NO rf on the external power meter. A signal can be heard on a monitor receiver using <bset> <ant> changes the subrx receive path as expected but doesnt affect the tx output I was using the 2.82 software. I rolled back to 2.76 but still have the same issue Dave ww2r ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
