Re: [Elecraft] PR6-10 Poser, Cont'd
If you have the KAT3 installed remember to set DIGIOUT1 control line for each antenna port, 1 and 2.

Re: [Elecraft] PR6-10 Poser, Cont'd
Ed, You may have too many variables to determine what is causing the problem. Try a few things first to isolate where it is failing. First connect a BNC jumper between RX ANT OUT and RX ANT IN. Does the K3 hear a signal at the same strength with RX ANT set on as it does with it set off? It should. If not, there is a problem with the K3 RX ANT, contact support. Then connect the PR6-10 to the RX ANT jacks on the K3 and connect it for power at all times (no selection from pin 11 - install jumper P2 in PR6-10) - when you select RX ANT, the signal strength should increase. If it does not, you may have a faulty PR6-10, contact support. Lastly, remove jumper P2 from the PR6-10 and connect using ACC pin 11 - connect only the PR6-10 to the ACC connector. Does it work as expected? If not, check the menu settings for DIGIOUT1. Should the menu settings be correct and it still does not work, measure the voltage on the white wire with the preamp selected and not selected. It should be zero when selected and greater than 3 volts when the preamp is not selected. If all the above work as expected, start putting the rest of the cabling in place - one cable at a time. Stop if the preamp stops working because you just installed the cable that makes it fail. 73, Don W3FPR On 6/16/2014 1:03 PM, Dauer, Edward wrote: Thanks Mike, Fred, and others . . .

Re: [Elecraft] PR6-10 Poser, Cont'd
Have you tried it in manual mode where power is applied at all times so you know the pre amp is working as expected? On 6/16/2014 11:03 AM, Dauer, Edward wrote: Thanks Mike, Fred, and others . . .

Fred points out that pin 11 would keep the preamp on rather than off; second, having used a KAT (and a KPA) with the K3 since the KAT first came out, I've worked through the cabling business and had it all solved so far as the KAT is concerned. And most convincing, one of my attempts was done with the K3 a cappella, so to speak -- I disconnected everything except the power supply and the antenna and the PR6-10, connecting only the unique 15-pin cable that was supplied with the PR6-10-- with the same result. Fred's book (2d Ed.) shows the block diagram of the PR6 (same as the 6-10, I assume) and the KVX3, but the examples use a separate antenna in ANT 2 for the preamped band. I have but one coax line coming into the shack for every band -- the antenna switch is remote, out where the antennas are. (Reduces the number of holes you have to drill in the house.) That feed line is in the K3 at ANT 1, and ANT 1 is selected. The plan was to keep just one feed line and select the preamp in for ten meters and out for everything else. Am I trying to do something that's not possible? Nothing I've seen in the Elecraft papers says anything about not using ANT 1 for everything including what the preamp is supposed to be preamping . . . Any further ideas? Tnx! Ted, KN1CBR Hi Ted, If you are using a KPA500 and a PR6 you will have to remove pin 11 from the cable that goes to the KPA500. It has popped up on this reflector once or twice but it is not mentioned in either the PR6 or the KPA500 instructions. If you wonder if this will work just pull the 15 pin cable off of the KPA500 and you'll see that the PR6 works as you would expect it to work. 73, Mike K2MK Dauer, Edward wrote I need to ask for help configuring a PR6-10 on the K3. Installed OK, removed the internal jumper per instructions and am using the control line on a Y splitter to allow the KPA and KAT to connect to the K3 as well. Physically, all seems fine, and the K3, P3, KPA and KAT work just as they always did. Then to operate the pre-amp I configured digout1 to ?on? for 28 Mhz on the K3, per instructions. OK so far. The PR6-10 manual says ?Tap RX ANT to enable preamplifier.? When I do so the noise level goes way down and the signals disappear, as if there were no antenna connected to the receiver. Removing the power plug from the preamp made no difference in either mode ? RX ANT on or off. I recall when building the K3 that there were elections to be made about antenna configurations when installing the sub receiver and/or the KXV3. I also remember that there are a myriad of ways the antennas can be routed via the configuration menus. I have a feeling that the elections and internal configurations I originally made in the K3 are not compatible with getting the PR6-10 to work simply by pressing RX ANT, but I can?t reason my way through it all.

Re: [Elecraft] PR6-10 Poser, Cont'd
I just hooked mine up this weekend. I was using Ant2, but I don't see that being a significant difference. Initially, I was seeing the same symptom but it went away. I am thinking that a power cycle might have enabled something, but I am only guessing. I was doing some contesting on 6M(local) this weekend and it worked like a champ. I also have the sub, and it was also on Ant2 at the time.

Thanks Mike, Fred, and others . . . I will try the pin 11 mod though I fear that's not the problem, for three reasons. Fred points out that pin 11 would keep the preamp on rather than off; second, having used a KAT (and a KPA) with the K3 since the KAT first came out, I've worked through the cabling business and had it all solved so far as the KAT is concerned.
