I have built, installed and tested a keying circuit and followed the instructions to interface the KXPA100 with the "Basic Operation with any Transceiver". My KX3 requires PA Mode to be On allowing all antenna matching to be done by the KXPA100. With the K2 and its KAT2 ATU, I cannot identify how to bypass the ATU and allow the KXPA100's ATU to do the antenna matching. I have previously adjusted the KXPA100's ALC to accommodate an FT817.
Or, use J4 Ant on the RF Board as the interface to the KXPA100. The relays in the K2 will click and have no effect on the matching to the KXPA100. In this configuration, a 1.5 Watt unattenuated by the 3db KXPA100 Switch, shows a power output of 60 Watts on all KXPA100 modes. Any comments and/or observations are most welcome. 73, Mark G3XYS MacBook Pro NNNN ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
