Re: [Elecraft] KPA500-KAT500 tuning settings

Why is it obvious?  Actually, I don't. I have a tri-band Yagi that I also tune for 12 and 17.  So each band has a different tuning solution, which has nothing to do with a different antenna spigot.  And note I said, "for instance", i.e. for example. K3WYC has pointed out the pitfall of

Re: [Elecraft] KPA500-KAT500 tuning settings

"You can only connect a maximum of three antennas to a KAT500." Any time you use a KAT500 with multiple antennas connected, and you also use a KPA500, you run the risk that the band change RF blip will fault the tuner, or the amplifier, or both. This happens because the RF pulse gets to the

Re: [Elecraft] KPA500-KAT500 tuning settings

So you obviously have a different antenna on 10m than you do on 20m. Do you have different antennas on every band? You can only connect a maximum of three antennas to a KAT500. I use a Top Ten band decoder to automatically switch an external coax relay box, no TX is necessary. John KK9A

Re: [Elecraft] KPA500-KAT500 tuning settings

Though it works, best practice when using a K3 is to use AUX cables. The AUXBUS line (pin 2) in the AUX cable provides notification to the K3 as the amp switches from standby to operate, so drive power can be adjusted automatically AUXBUS also lets you use the band buttons on the KPA500 to

Re: [Elecraft] KPA500-KAT500 tuning settings

Well, to me it wasn't easy.  If the KPA500 and KAT500 are used together and the KPA500 is turned on, then the tuner tracks (VFO A only) but I found it necessary to fuss with some timing to keep the KAT500 from changing tuning states during a transmission.  If the KPA500 isn't tuned on, then the
