Hi all, I have an end-fed antenna with some random wire. The UNUN at one end of it has three sockets to plug the random wire in: 1:4, 1:9 and 1:16. My KX3 has the built-in ATU. I now want to find out on which band I best use which one of the sockets. As a first step, I wrote a simple program

Using the menu entry PREAMP, you can actually select 10 dB, 20 dB or 30 dB. According to the manual, 30 dB is the default for 6m. The 10 dB preamp is also the isolation amp. The 20 dB preamp has a better noise figure than the 20 dB one. The 30 db preamp is just the concatenation of the two

Re: [Elecraft] Vedr: [KX3] Does the KX3 support the Kenwood Master/Slave connection?

But the post only describes what to do on the controlling KX3, what needs to be done in order for the KX3 to receive frequency information? I'd say ... nothing. If the baudrates match and the NULL-modem cable is correct, then the KX3 sends just normal commands whenever something changes.

The KX3 can send and receive on any frequency, not only on HAM frequencies. As always, it's the responsibility of the operator to stay the legal, frequency-wise, power-wise and bandwidth-wise. The rig doesn't have some way of chanellizing. You have either to setup the exact frequency (and make
