Re: [Elecraft] KPA500+KAT500 interfacing.
The answer may be no, but you're not responding to the question asked. The KPA500 can be switched with Serial or BCD data, in addition to the Elecraft Aux Bus. I simply want to know: 1) does the KAT500 also switch with BCD data and 2) if so, can those data come from a KPA500 that is being controlled with serial data.

Re: [Elecraft] KPA500+KAT500 interfacing.
I can answer this. I believe the answer to the first question is yes. The KAT500 can follow the BDC band data. The answer to the second is definitely no. The KPA500 does not output (nor does it have the capability) BCD band data. The port has input, but does not have output drive. To go further, while the KPA can talk over the Auxbus, the KAT does not have capability to decode the data. In fact the only devices with the capability to decode KPA500 Auxbus data are the K3, K3S and K4. While both can follow Kenwood-format serial data, and both will respond to a short transmission burst, there is an advantage to having the KAT500 follow the transceivers receive frequency since it keeps the antenna properly matched for the received frequency. In order to do this you really need to have the KAT receive the transceiver frequency stream. As others have noted, it can listen to Kenwood FA responses (which the KPA can poll for). Several folks have created rather interesting boxes that can receive band data from transceivers and communicate it to the KPA500 and KAT500. You might want to talk with Andy, K3WYC about his rather interesting project. 73, Jack, W6FB > On Nov 17, 2020, at 8:27 PM, Wes wrote: > > The answer may be no, but you're not responding to the question asked. > > The KPA500 can be switched with Serial or BCD data, in addition to the > Elecraft Aux Bus.

Re: [Elecraft] KPA500+KAT500 interfacing
I received a bit of further information this morning. The KAT500 only uses the band data to validate that the received frequency (from the K3) is on the indicated band. It does not use it for anything else. Further, the KPA500 only uses band data to select the band. In general, the KPA doesn’t care about the frequency - it really has no frequency-sensitive elements. The KPA does not receive frequency from the K3, and only uses the Kenwood data (or Icom band voltage) to select a band. Thus there is no data to be sent. I believe you are searching for a solution that gathers transceiver frequency and sends it to the KAT500. Or, allow the KAT500 to use its built-in frequency measurement system to select the bin.

Re: [Elecraft] KPA500+KAT500 interfacing
Mostly the cable is a pass through. The KAT500 has a relay to interrupt the amp key line during ATU tuning, and the KAT500 can observe (but not change) the exciter-controlled band lines. The ATU needs the frequency. The amp needs the band. Both amp and ATU have TX freq counters. Both amp and ATU have publicly documented mechanisms to be controlled by external automation to return to freq-appropriate settings before transmission. We provide automation from K3, K3S, and K4 when you use the optional 15-pin ACC cables and select the appropriate settings in exciter, amp, and ATU. These are convenient, but not the only way the amp and ATU can be used. If the amp were able to set band lines for the ATU, it would be of marginal utility. The ATU could return to the last used setting on that band. As soon as you QSY, the ATU would probably need to move, based on the tx freq count. 73 de Dick, K6KR > On Nov 18, 2020, at 10:18, j...@kk9a.com wrote: > > So what does the HD15 cable do from the KAT500 to the KPA500?

Re: [Elecraft] KPA500+KAT500 interfacing
Two things. First, you are right, it passes the signals through from the radio. The second is that it can break the PTT line (in that pass-through) when the KAT needs to tune or otherwise change the relays while the system is transmitting (PTT being active). Note that both the KAT and the KPA use many of the signals on the AuxIO. These include the BAND lines, PTT, and importantly, the AuxBus line. The KPA500 talks on the Auxbus (but does not listen), while the KAT listens on the Auxbus. Because of the way the KPA encodes its data, the KAT cannot receive any data from the KPA, but only that coming from the transceiver. That is kind of an important point - there is no communications between the KPA500 and the KAT500, which eliminates the ability to do really close control between the two. 73!

Re: [Elecraft] KPA500+KAT500 interfacing.
From the KAT500 manual: When the KAT500 is used with an Elecraft K3 transceiver, the K3 can be configured to cause the KAT500 to follow changes in the K3’s VFO frequency during receive. This requires frequency, not band data. Tuning the K3 big knob results in a change of tuning solutions for antennas that require those solutions. After stopping tuning for a brief moment, one can hear the relays change. 73, Bill, K8TE -- Sent from: http://elecraft.365791.n2.nabble.com/ __ 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 Message delivered to arch...@mail-archive.com
Re: [Elecraft] KPA500+KAT500 interfacing
Some people seem to get quite hostile when I carefully distinguish between "band data" and "frequency data". For that reason I didn't emphasize that KAT500 needs FREQUENCY not BAND. The cable for "KPA500 polls Kenwood and KPA500 and KAT500 listen to Kenwood" can be cobbled together for probably under $10 assuming you don't have the connectors and cable in the junk bin. You can also buy the cable from Elecraft. It works fine as long as you accept that KAT500 can only follow VFO A (limitation of current firmware). I was not satisfied with this (and other limitations) so I launched on a long, educational, rewarding, and sometimes frustrating, project to build a controller that made the Kenwood/KPA500/KAT500 interface work the way I though it should (I don't claim it works correctly , only that it works the way I want it to).

Re: [Elecraft] KPA500+KAT500 interfacing
I would like to see an Icom CI-V interface for the KPA500/KAT500 combination. This is built into the KPA1500 which is a combination amp/tuner/antenna selector switch. The KPA1500 "speaks" Elecraft, Kenwood, Yaesu, and Icom. The KPA500 can use Icom "band data" voltages but that doesn't support the WARC bands. There is also no communication with the KAT500 to tell it what band/antenna to use. Yes, the KPA500/KAT500 combination switches perfectly to the proper band, frequency, and antenna on *transmit *but does nothing on receive. When just listening it is necessary to manually press the ANT(tenna) button on the KAT500 to select the proper antenna for the selected frequency (band) on the Icom radio. If you are trying to scan memories that doesn't work at all. Having the ability for the KAT500 to follow the receiver so it could select the proper band/antenna would be very helpful. Has anybody built such an interface or know of an existing commercial device that will perform the above function? 73, Ken WA2LBI On Wed, Nov 18, 2020 at 4:01 PM Andy Durbin wrote: > Some people seem to get quite hostile when I carefully distinguish between > "band data" and "frequency data".

Many years ago, a homebrew CI-V to RS232 interface was published in QST, and about 15 years ago, I bought two at a Chicago area hamfest that a ham had made a small business of building and selling. It worked fine with the IC746 that I owned at the time. 73, Jim K9YC __ 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 Message delivered to arch...@mail-archive.com
