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

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

I have thoroughly enjoyed my KXPD2 iambic paddle. I do not consider the finger spacing “bizarrely wide”. My Kent dual lever paddle which I used happily for decades, is spaced about the same. We all have our own preferences, so when I ordered my N3ZN paddle some years ago I did opt for a

[Elecraft] KEYOUT_LP issue

Hello group. I have some issue with KEYOUT_LP. I have use KEYOUT_LP as PTT for my transverters and PA, but have problem when powering OFF my K3S. All equipment connected to the circuit controlled by KEYOUT_LP going to transmit mode (PTT is engaged) then receive mode(PTT disengaged ) 3-5 times

Wes, The answer is NO. The KAT500 and KPA500 take their AUX commands from the K3(S). On 11/17/2020 1:11 PM, Wes wrote: I have a K3S interfaced to the KAT500 and KPA500 using the Aux cables. If I was to replace the K3S with a rig with only RS232 control of the KPA500, will the Kat500 still

"If I was to replace the K3S with a rig with only RS232 control of the KPA500, will the Kat500 still follow along using the Aux cables." I'm pretty sure the answer is "No". AUX cables don't do anything unless connected to an AUX compatible rig. It is, however, easy to feed the KAT500 with

I have a K3S interfaced to the KAT500 and KPA500 using the Aux cables. If I was to replace the K3S with a rig with only RS232 control of the KPA500, will the Kat500 still follow along using the Aux cables.  The Xcvr and Amp connections on the KAT500 seem to be more or less a pass through. I

Replacing the final output MOSFETs in my K3's low power amp appears to have fixed its transmit power issues. Thank you everyone on the K3 forums for your shared advice and experiences. The "3 screw" tests were pointing to a bad output transistor in the LPA. The idle current increase on the K3
