[Elecraft] K2 interface with steppIR and computer
I built my serial cable for the K2 to talk to my SteppIR controller from the Elecraft manual. Works just fine. It also talks to my computer for HRD, N1MM etc. So I decided to work on having the two interfaces work together like they did with my IC 746 Pro. However, building a Y cable doesn't seem to be working out the way I want! Each device works fine when I have it plugged into the Y cable by itself but when I plug in both at the same time, One or the other will freeze up. I am simply using pins 2, 3 and 5 from the K2 serial port wired straight through to the female DB 9s at the device end and have 7 and 8 jumpered at the external device end. What am I doing wrong? My KPA500 arrives on Monday so I'd like to get this resolved before my next project!

Re: [Elecraft] K2 interface with steppIR and computer
Got it! It didn't make sense to me but once I inserted the "S13" cable from the K2 to the Y cable, removed the TXD from the SteppIr DB9 and changed the jumper from pin 8 to pin 9 per SteppIR and Don, it all worked. Whew! Ok, only the S13 cable didn't make sense but it works so I guess it doesn't have to make sense to me.

[Elecraft] KPA500
Received KPA500 #636 yesterday afternoon. Took an hour for inventory and then a bit over 5 hours to assemble it. No missing parts and it worked just fine the first time I fired it up.

[Elecraft] 5 watts to KPA500
Hi, Out of curiosity ... those fortunate owners of the KPA500 could take a look and let me know what output they produce when the input to the amp is exactly 5W Into a 1.3-1 SWR on 7250 I get right at 50 watts output for 5 watts input. My dummy load is on back order from MFJ or I could be more accurate!

[Elecraft] footswitch and amp
So, then, this begs a question. I have a K3 with an Ameritron AL-811H. I key the K3 with a Heil foot switch connected to a Heil ProSet 5. When I tried keying my amp off the red cable on the foot switch, I didn't get any amp keying. When I connected an RCA phono cable between the K3's key out jack and the amp's relay, everything works fine and dandy. Is there some setting on the K3 I missed to allow the amp to key from the foot switch instead of from the rig's TX? Thanks and 73, Ian Kahn, KM4IK Roswell, GA I'm not sure why you want to key the amp instead of the rig. I ran an 811H for years with my Icom 746 Pro and my K2s with a footswitch to the radio connected to my ProSet 5.. Same way I now run my K2 and my KPA500. Since I don't have a K3 (yet) I guess I might be missing something but since the amp, whether the 811H or KPA500 doesn't key until the radio does, I wouldn't think this would be an issue. And, I'm not sure how it would work keying the amp without the radio. Maybe because the KPA500 and K3 are basically symbiotic its not an issue but I certainly wouldn't have been able to use the IC 746 Pro or my K2 by keying the amp. What am I missing?

[Elecraft] K3 sub receiver
My K3/100 kit arrives tomorrow. I did not order the sub receiver. I have only a vertical here and have some antenna restrictions (height) I use a SteppIR BigIR and it works great for me with my height restriction. So, unless one of you can explain to me why I should have the sub receiver with only one antenna, I'm leaving it the with one!

[Elecraft] sub receiver
I've had my ticket since 1974 (WN4IKG) I have owned over 25 rigs but never had one with two receivers. I 've always worked split with two VFOs but after a few emails from you guys and thinking about it (brain taxing) I can see where the second receiver would be useful. When I was working the HK0NA group, I just transmitted where they said they were listening but they had about a 10 kHz spread so it was a guess whether they would hear me or not. It would be nice to know exactly where they are listening. Thanks for the advice. Love the reflector. Shipped my K2 off this morning and sold my IC 7000 last weekend. I am sans rig until this afternoon when UPS comes! I haven't been without a rig in I don't know how long! Its lonely. John KE4D My K3/100 kit arrives tomorrow. I did not order the sub receiver.

[Elecraft] tuners

If you willl only be using it with the K2/10, I highly recommend the Elecraft KAT2. It will remember the settings for 2 antennas per band and works seamlessly with the K2. If your need is for a remote tuner that can be located at the antenna feedpoint, then the LDG or other similar tuners are the best choice I've had a couple of SGC tuners in antenna restricted environments. They worked pretty well and I never had a failure. I've also had I think 4 Icom AH-4s. I have one on my RV right now tuning an Eagle One 30 foot collapsible mast. To get the Icom to work with most non Icom rigs requires a small construction project but its not a big deal. Those AH-4s have been super in the RV over the years.

[Elecraft] KPA BRacket and top cover
Yes Chuck. Mine does the same thing. T thought loosing the side a bit might make it "pop" back flush and then retighten the screws but that didn't help. Your right, it does detract a bit cosmetically from the amp (which is a great product) I now have my month old KPA500 interfaced with my day old K3. Nice combination.

The result is that the top cover protrudes above the front panel in the center by a small amount, perhaps 1mm. At the rear the top cover is flush with the rear panel in the center...no protrusion at all.

[Elecraft] serial to USB
I have zero serial ports on the computer in my shack. I use Elecrafts Serial/USB converter for one connection, Another FTDI unit I bought on Amazon for the other and piggy back my SteppIR controller with a Y cable to the main rig/computer interface. I have no issues at all. I'm quite happy with the way they work. I've used a lot of Serial to USB converters since serial ports started disappearing and these FTDI ones seem to work just fine.

[Elecraft] k2/100 fuse holder
I never use those fuse holders. My power cord for the K2 goes from a fused (blade type) in an MFJ DC outlet to the rig.However, you and I discussed the issue with those MFJ Outlets a week or so ago!

[Elecraft] K2 DOA at second power up test
Ok, I've done a lot of dumb things in 37 years of amateur radio but when constructing my second K2 a few weeks ago, I dropped a piece of component wire on the RF board while doing the second power up test on the receiver. Bam, no power at all, no lights, no relays nada. I thought I blew D10 on the RF board but Elecraft tells me it leaks anyway. I changed it nonetheless, no joy. I get 12 volts on the main bus on the RF board until I hit the power switch. Then the voltage drops to 2.5 or so. I lifted the 5 and 8 volt regulator output leads, still low voltage there. Changed them also but still no joy. I'm at a loss where to look next. I cannot find anything that warms up, looks bad, measures the wrong resistance, just low voltage. Low enough that the relays don't activate and the display is a dismal green with no power to it. Any suggestions other than buying another Icom or Kenwood? I could say the rig is KOA instead of DOA since I killed it!

Re: [Elecraft] K2 DOA at second power up test
Thanks Don, Elecraft told me the same thing. However, as I told them, I'm on the second power up test in the manual, there is no T3 or PA transistor in on the board at this time. I've built the front panel, the control board and the receiver, no transmitter yet. I'm pretty sure its something in the 12v line, I just can't find it. I wondered about F1 but I show 12 volts on both sides of it so I guess its ok. And the power supply is fine, I have 12 volts on the RF board until I push the on switch on my front panel. Then the voltage drops to about 2.5. I figure something is pulling it down, I just need to find it!
