Kept this for a backup/just in case radio when I got the K4. Love the K4 and have a KX3 as a backup just in case the K4 does have an issue and needs to go back. K3S, ser # 11231 100W option Tuner Gene

Look at the bottom of page 43 of the K3 assembly manual. It shows where that switch is at. The next page shows the switch in more detail. Ken WR7D

Problem solved. I once again studied the schematics and wrote out a logic table for the various signal paths for P3 enabled/disabled and USB enabled/disabled. After that exercise, it looked like P3 En

Henk, thanks for that explanation. I was particularly interested in this statement: However in both cases there is Pin 1 grounded, indicated that the P3 is being used (meaning RS232 should be routed e

Thanks Paul. That's a very good description. I had pretty much deduced that after going over the manuals and schematics the past two days. It's good to see my thinking confirmed. The specific problem

Yes, it completely latches. The springy fingers are on the jack and the other cable works. They do look good though. After digging through the manuals and schematics, I'm still not sure if the E980297

I just did a continuity check of the E980297 cable and it's fine. I'm not sure what else to check. I suppose there could be some issue with the KIO3B, but if that's the case, why is the other cable wo

Elecraft has changed the wording on the K3s page for options/accessories. It says they've closed the window for ordering, but there may be extras because of minimum part orders from suppliers. It says

I'm trying to figure out if I have a configuration problem or a bad cable. I'm trying to set up a K3s/P3 for remote ops using the RCForb software. I have the K3s set to RS232: 38400. When I connect th

Thanks. I did find some references to one, an MFJ-950K3 / MFJ-950K. I couldn't find any place that had them for sale. I did find a couple of reviews so I'm guessing they produced them at one point. Th

Just acquired an Elecraft K3S, but it doesn't have the internal tuner. If you've got a spare laying around or have one installed but don't operate barefoot, I'm interested. Thanks Ken WR7D

Thanks. I thought the KAT500 manual said 7 watts. Is 20 watts a more practical, field tested power? I know the short document that talks about integrating the K3S/KPA500/KAT500 says to set the K3S to

Thanks. I was thinking about this from a remote control standpoint. I guess I can just make a table of K3S readings to KPA500 readings for remote ops. Unless there is a different way to accomplish thi

Thanks. I was going to ask this question also, but forgot. It doesn't look like the K3S will display the power level from the KPA500 like the KXPA100 and KX3 combo does. Is that correct? Ken WR7D

I have a new to me KPA500/KAT500 combo to go along with my K3S. I understand the standby and operate modes of the amp and the different power levels for each that the K3S can use. My question is will

I haven't found much information on this subject. Most things I've found deal with using the KX3 to control a remote K3(S). I would like to remotely control a KX3 and still have good CW performance us

Looking for a KRX3A sub receiver for my K3S. With or without filters is OK. Would also consider a radio that has the sub receiver installed. If a K3, it would need to have the upgraded KSYN3A synthesi

I have a workable solution thanks to everyone. I am using both RemoteRig boxes. It took a bit of effort to get them to talk to each other between the house and shop, but I got that sorted out. I basic

Thanks for the info so far. That's a shame about the Win4K3Suite, but that wasn't a necessary requirement. I really don't use the logging software for CAT control. I mainly just use that connection so
